-Description
------------
-
-This system call opens a named audio device (e.g.

-succeeded, the device will be ready for use. The significance of
-blocking or non-blocking mode is described in the documentation for
-functions where there is a difference. It does not affect the semantics
-of the open() call itself. A device opened in blocking mode can later be
-put into non-blocking mode (and vice versa) using the F_SETFL command
-of the fcntl system call. This is a standard system call, documented in
-the Linux manual page for fcntl. Only one user can open the Audio Device
-in O_RDWR mode. All other attempts to open the device in this mode will
-fail, and an error code will be returned. If the Audio Device is opened
-in O_RDONLY mode, the only ioctl call that can be used is
-AUDIO_GET_STATUS. All other call will return with an error code.

-
- - int id
-
- - audio sub-stream id
-
-Description
------------
-
-This ioctl selects which sub-stream is to be decoded if a program or
-system stream is sent to the video device. If no audio stream type is
-set the id has to be in [0xC0,0xDF] for MPEG sound, in [0x80,0x87] for
-AC3 and in [0xA0,0xA7] for LPCM. More specifications may follow for
-other stream types. If the stream type is set the id just specifies the
-substream id of the audio stream and only the first 5 bits are
-recognized.
-
-Return Value
-------------
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.

-Digital TV Audio Device
-#######################
-
-The Digital TV audio device controls the MPEG2 audio decoder of the Digital
-TV hardware. It can be accessed through ``/dev/dvb/adapter?/audio?``. Data
-types and ioctl definitions can be accessed by including
-``linux/dvb/audio.h`` in your application.
-
-Please note that some Digital TV cards don't have their own MPEG decoder, which
-results in the omission of the audio and video device.
-
-These ioctls were also used by V4L2 to control MPEG decoders implemented
-in V4L2. The use of these ioctls for that purpose has been made obsolete
-and proper V4L2 ioctls or controls have been created to replace that
-functionality.

-****************
-Audio Data Types
-****************
-
-This section describes the structures, data types and defines used when
-talking to the audio device.
-
-.. c:type:: audio_stream_source
-
-The audio stream source is set through the AUDIO_SELECT_SOURCE call
-and can take the following values, depending on whether we are replaying
-from an internal (demux) or external (user write) source.
-
-
-.. code-block:: c
-
- typedef enum {
- AUDIO_SOURCE_DEMUX,
- AUDIO_SOURCE_MEMORY
- } audio_stream_source_t;
-
-AUDIO_SOURCE_DEMUX selects the demultiplexer (fed either by the
-frontend or the DVR device) as the source of the video stream. If
-AUDIO_SOURCE_MEMORY is selected the stream comes from the application
-through the ``write()`` system call.
-
-
-.. c:type:: audio_play_state
-
-The following values can be returned by the AUDIO_GET_STATUS call
-representing the state of audio playback.
-
-
-.. code-block:: c
-
- typedef enum {
- AUDIO_STOPPED,
- AUDIO_PLAYING,
- AUDIO_PAUSED
- } audio_play_state_t;
-
-
-.. c:type:: audio_channel_select
-
-The audio channel selected via AUDIO_CHANNEL_SELECT is determined by
-the following values.
-
-
-.. code-block:: c
-
- typedef enum {
- AUDIO_STEREO,
- AUDIO_MONO_LEFT,
- AUDIO_MONO_RIGHT,
- AUDIO_MONO,
- AUDIO_STEREO_SWAPPED
- } audio_channel_select_t;
-
-
-.. c:type:: audio_status
-
-The AUDIO_GET_STATUS call returns the following structure informing
-about various states of the playback operation.
-
-
-.. code-block:: c
-
- typedef struct audio_status {
- boolean AV_sync_state;
- boolean mute_state;
- audio_play_state_t play_state;
- audio_stream_source_t stream_source;
- audio_channel_select_t channel_select;
- boolean bypass_mode;
- audio_mixer_t mixer_state;
- } audio_status_t;
-
-
-.. c:type:: audio_mixer
-
-The following structure is used by the AUDIO_SET_MIXER call to set the
-audio volume.
-
-
-.. code-block:: c
-
- typedef struct audio_mixer {
- unsigned int volume_left;
- unsigned int volume_right;
- } audio_mixer_t;
-
-
-.. _audio_encodings:
-
-audio encodings
-===============
-
-A call to AUDIO_GET_CAPABILITIES returns an unsigned integer with the
-following bits set according to the hardwares capabilities.
-
-
-.. code-block:: c

- #define AUDIO_CAP_DTS 1
- #define AUDIO_CAP_LPCM 2

-/* Budgetpatch note:
- * Original hardware design by Roberto Deza:
- * There is a DVB_Wiki at
- * https://linuxtv.org
- *
- * New software triggering design by Emard that works on
- * original Roberto Deza's hardware:
- *
- * rps1 code for budgetpatch will copy internal HS event to GPIO3 pin.
- * GPIO3 is in budget-patch hardware connectd to port B VSYNC
- * HS is an internal event of 7146, accessible with RPS
- * and temporarily raised high every n lines
- * (n in defined in the RPS_THRESH1 counter threshold)
- * I think HS is raised high on the beginning of the n-th line
- * and remains high until this n-th line that triggered
- * it is completely received. When the reception of n-th line
- * ends, HS is lowered.
- *
- * To transmit data over DMA, 7146 needs changing state at
- * port B VSYNC pin. Any changing of port B VSYNC will
- * cause some DMA data transfer, with more or less packets loss.
- * It depends on the phase and frequency of VSYNC and
- * the way of 7146 is instructed to trigger on port B (defined
- * in DD1_INIT register, 3rd nibble from the right valid
- * numbers are 0-7, see datasheet)
- *
- * The correct triggering can minimize packet loss,
- * dvbtraffic should give this stable bandwidths:
- * 22k transponder = 33814 kbit/s
- * 27.5k transponder = 38045 kbit/s
- * by experiment it is found that the best results
- * (stable bandwidths and almost no packet loss)
- * are obtained using DD1_INIT triggering number 2
- * (Va at rising edge of VS Fa = HS x VS-failing forced toggle)
- * and a VSYNC phase that occurs in the middle of DMA transfer
- * (about byte 188*512=96256 in the DMA window).
- *
- * Phase of HS is still not clear to me how to control,
- * It just happens to be so. It can be seen if one enables
- * RPS_IRQ and print Event Counter 1 in vpeirq(). Every
- * time RPS_INTERRUPT is called, the Event Counter 1 will
- * increment. That's how the 7146 is programmed to do event
- * counting in this budget-patch.c
- * I *think* HPS setting has something to do with the phase
- * of HS but I can't be 100% sure in that.
- *
- * hardware debug note: a working budget card (including budget patch)
- * with vpeirq() interrupt setup in mode "0x90" (every 64K) will
- * generate 3 interrupts per 25-Hz DMA frame of 2*188*512 bytes
- * and that means 3*25=75 Hz of interrupt frequency, as seen by
- * watch cat /proc/interrupts
- *
- * If this frequency is 3x lower (and data received in the DMA
- * buffer don't start with 0x47, but in the middle of packets,
- * whose lengths appear to be like 188 292 188 104 etc.
- * this means VSYNC line is not connected in the hardware.
- * (check soldering pcb and pins)
- * The same behaviour of missing VSYNC can be duplicated on budget
- * cards, by setting DD1_INIT trigger mode 7 in 3rd nibble.

-/* OLD (Original design by Roberto Deza):
-** This code will setup the SAA7146_RPS1 to generate a square
-** wave on GPIO3, changing when a field (TS_HEIGHT/2 "lines" of
-** TS_WIDTH packets) has been acquired on SAA7146_D1B video port;
-** then, this GPIO3 output which is connected to the D1B_VSYNC
-** input, will trigger the acquisition of the alternate field
-** and so on.
-** Currently, the TT_budget / WinTV_Nova cards have two ICs
-** (74HCT4040, LVC74) for the generation of this VSYNC signal,
-** which seems that can be done perfectly without this :-)).
-*/
-
-/* New design (By Emard)
-** this rps1 code will copy internal HS event to GPIO3 pin.
-** GPIO3 is in budget-patch hardware connected to port B VSYNC
-
-** HS is an internal event of 7146, accessible with RPS
-** and temporarily raised high every n lines
-** (n in defined in the RPS_THRESH1 counter threshold)
-** I think HS is raised high on the beginning of the n-th line
-** and remains high until this n-th line that triggered
-** it is completely received. When the reception of n-th line
-** ends, HS is lowered.
-
-** To transmit data over DMA, 7146 needs changing state at
-** port B VSYNC pin. Any changing of port B VSYNC will
-** cause some DMA data transfer, with more or less packets loss.
-** It depends on the phase and frequency of VSYNC and
-** the way of 7146 is instructed to trigger on port B (defined
-** in DD1_INIT register, 3rd nibble from the right valid
-** numbers are 0-7, see datasheet)
-**
-** The correct triggering can minimize packet loss,
-** dvbtraffic should give this stable bandwidths:
-** 22k transponder = 33814 kbit/s
-** 27.5k transponder = 38045 kbit/s
-** by experiment it is found that the best results
-** (stable bandwidths and almost no packet loss)
-** are obtained using DD1_INIT triggering number 2
-** (Va at rising edge of VS Fa = HS x VS-failing forced toggle)
-** and a VSYNC phase that occurs in the middle of DMA transfer
-** (about byte 188*512=96256 in the DMA window).
-**
-** Phase of HS is still not clear to me how to control,
-** It just happens to be so. It can be seen if one enables
-** RPS_IRQ and print Event Counter 1 in vpeirq(). Every
-** time RPS_INTERRUPT is called, the Event Counter 1 will
-** increment. That's how the 7146 is programmed to do event
-** counting in this budget-patch.c
-** I *think* HPS setting has something to do with the phase
-** of HS but I can't be 100% sure in that.
-
-** hardware debug note: a working budget card (including budget patch)
-** with vpeirq() interrupt setup in mode "0x90" (every 64K) will
-** generate 3 interrupts per 25-Hz DMA frame of 2*188*512 bytes
-** and that means 3*25=75 Hz of interrupt frequency, as seen by
-** watch cat /proc/interrupts
-**
-** If this frequency is 3x lower (and data received in the DMA
-** buffer don't start with 0x47, but in the middle of packets,
-** whose lengths appear to be like 188 292 188 104 etc.
-** this means VSYNC line is not connected in the hardware.
-** (check soldering pcb and pins)
-** The same behaviour of missing VSYNC can be duplicated on budget
-** cards, by setting DD1_INIT trigger mode 7 in 3rd nibble.

------------
-
-This system call opens a named video device (e.g.

-
-When an open() call has succeeded, the device will be ready for use. The
-significance of blocking or non-blocking mode is described in the
-documentation for functions where there is a difference. It does not
-affect the semantics of the open() call itself. A device opened in
-blocking mode can later be put into non-blocking mode (and vice versa)
-using the F_SETFL command of the fcntl system call. This is a standard
-system call, documented in the Linux manual page for fcntl. Only one
-user can open the Video Device in O_RDWR mode. All other attempts to
-open the device in this mode will fail, and an error-code will be
-returned. If the Video Device is opened in O_RDONLY mode, the only
-ioctl call that can be used is VIDEO_GET_STATUS. All other call will
-return an error code.

------------
-
-This ioctl is for Digital TV devices only. To control a V4L2 decoder use the

-
-This ioctl call suspends the live video stream being played. Decoding

-playing process of the video stream using the VIDEO_CONTINUE command.
-If VIDEO_SOURCE_MEMORY is selected in the ioctl call

-Description
------------
-
-This ioctl is for Digital TV devices only. To get events from a V4L2 decoder
-use the V4L2 :ref:`VIDIOC_DQEVENT` ioctl instead.
-
-This ioctl call returns an event of type video_event if available. If
-an event is not available, the behavior depends on whether the device is
-in blocking or non-blocking mode. In the latter case, the call fails
-immediately with errno set to ``EWOULDBLOCK``. In the former case, the call
-blocks until an event becomes available. The standard Linux poll()
-and/or select() system calls can be used with the device file descriptor
-to watch for new events. For select(), the file descriptor should be
-included in the exceptfds argument, and for poll(), POLLPRI should be
-specified as the wake-up condition. Read-only permissions are sufficient
-for this ioctl call.

-The Digital TV video device controls the MPEG2 video decoder of the Digital
-TV hardware. It can be accessed through **/dev/dvb/adapter0/video0**. Data
-types and ioctl definitions can be accessed by including
-**linux/dvb/video.h** in your application.
-
-Note that the Digital TV video device only controls decoding of the MPEG video
-stream, not its presentation on the TV or computer screen. On PCs this
-is typically handled by an associated video4linux device, e.g.
-**/dev/video**, which allows scaling and defining output windows.
-
-Some Digital TV cards don't have their own MPEG decoder, which results in the
-omission of the audio and video device as well as the video4linux
-device.
-
-The ioctls that deal with SPUs (sub picture units) and navigation
-packets are only supported on some MPEG decoders made for DVD playback.
-
-These ioctls were also used by V4L2 to control MPEG decoders implemented
-in V4L2. The use of these ioctls for that purpose has been made obsolete
-and proper V4L2 ioctls or controls have been created to replace that
-functionality.

-Video Data Types
-****************
-
-
-.. _video-format-t:
-
-video_format_t
-==============
-
-The ``video_format_t`` data type defined by
-
-
-.. code-block:: c
-
- typedef enum {
- VIDEO_FORMAT_4_3, /* Select 4:3 format */
- VIDEO_FORMAT_16_9, /* Select 16:9 format. */
- VIDEO_FORMAT_221_1 /* 2.21:1 */
- } video_format_t;
-
-is used in the VIDEO_SET_FORMAT function (??) to tell the driver which
-aspect ratio the output hardware (e.g. TV) has. It is also used in the
-data structures video_status (??) returned by VIDEO_GET_STATUS (??)
-and video_event (??) returned by VIDEO_GET_EVENT (??) which report
-about the display format of the current video stream.
-
-
-.. _video-displayformat-t:
-
-video_displayformat_t
-=====================
-
-In case the display format of the video stream and of the display
-hardware differ the application has to specify how to handle the
-cropping of the picture. This can be done using the
-VIDEO_SET_DISPLAY_FORMAT call (??) which accepts
-
-
-.. code-block:: c
-
- typedef enum {
- VIDEO_PAN_SCAN, /* use pan and scan format */
- VIDEO_LETTER_BOX, /* use letterbox format */
- VIDEO_CENTER_CUT_OUT /* use center cut out format */
- } video_displayformat_t;
-
-as argument.
-
-
-.. _video-stream-source-t:
-
-video_stream_source_t
-=====================
-
-The video stream source is set through the VIDEO_SELECT_SOURCE call
-and can take the following values, depending on whether we are replaying
-from an internal (demuxer) or external (user write) source.
-
-
-.. code-block:: c
-
- typedef enum {
- VIDEO_SOURCE_DEMUX, /* Select the demux as the main source */
- VIDEO_SOURCE_MEMORY /* If this source is selected, the stream
- comes from the user through the write
- system call */
- } video_stream_source_t;
-
-VIDEO_SOURCE_DEMUX selects the demultiplexer (fed either by the
-frontend or the DVR device) as the source of the video stream. If
-VIDEO_SOURCE_MEMORY is selected the stream comes from the application
-through the **write()** system call.
-
-
-.. _video-play-state-t:
-
-video_play_state_t
-==================
-
-The following values can be returned by the VIDEO_GET_STATUS call
-representing the state of video playback.
-
-
-.. code-block:: c
-
- typedef enum {
- VIDEO_STOPPED, /* Video is stopped */
- VIDEO_PLAYING, /* Video is currently playing */
- VIDEO_FREEZED /* Video is freezed */
- } video_play_state_t;
-
-
-.. c:type:: video_command
-
-struct video_command
-====================
-
-The structure must be zeroed before use by the application This ensures
-it can be extended safely in the future.
-
-
-.. code-block:: c
-
- struct video_command {
- __u32 cmd;
- __u32 flags;
- union {
- struct {
- __u64 pts;
- } stop;
-
- struct {
- /* 0 or 1000 specifies normal speed,
- 1 specifies forward single stepping,
- -1 specifies backward single stepping,
- >>1: playback at speed/1000 of the normal speed,
- <-1: reverse playback at (-speed/1000) of the normal speed. */
- __s32 speed;
- __u32 format;
- } play;
-
- struct {
- __u32 data[16];
- } raw;
- };
- };
-
-
-.. _video-size-t:
-
-video_size_t
-============
-
-
-.. code-block:: c
-
- typedef struct {
- int w;
- int h;
- video_format_t aspect_ratio;
- } video_size_t;
-
-
-.. c:type:: video_event
-
-struct video_event
-==================
-
-The following is the structure of a video event as it is returned by the
-VIDEO_GET_EVENT call.
-
-
-.. code-block:: c
-
- struct video_event {
- __s32 type;
- #define VIDEO_EVENT_SIZE_CHANGED 1
- #define VIDEO_EVENT_FRAME_RATE_CHANGED 2
- #define VIDEO_EVENT_DECODER_STOPPED 3
- #define VIDEO_EVENT_VSYNC 4
- long timestamp;
- union {
- video_size_t size;
- unsigned int frame_rate; /* in frames per 1000sec */
- unsigned char vsync_field; /* unknown/odd/even/progressive */
- } u;
- };
-
-
-.. c:type:: video_status
-
-struct video_status
-===================
-
-The VIDEO_GET_STATUS call returns the following structure informing
-about various states of the playback operation.
-
-
-.. code-block:: c
-
- struct video_status {
- int video_blank; /* blank video on freeze? */
- video_play_state_t play_state; /* current state of playback */
- video_stream_source_t stream_source; /* current source (demux/memory) */
- video_format_t video_format; /* current aspect ratio of stream */
- video_displayformat_t display_format;/* selected cropping mode */
- };
-
-If video_blank is set video will be blanked out if the channel is
-changed or if playback is stopped. Otherwise, the last picture will be
-displayed. play_state indicates if the video is currently frozen,
-stopped, or being played back. The stream_source corresponds to the
-selected source for the video stream. It can come either from the
-demultiplexer or from memory. The video_format indicates the aspect
-ratio (one of 4:3 or 16:9) of the currently played video stream.
-Finally, display_format corresponds to the selected cropping mode in
-case the source video format is not the same as the format of the output
-device.
-
-
-.. c:type:: video_still_picture
-
-struct video_still_picture
-==========================
-
-An I-frame displayed via the VIDEO_STILLPICTURE call is passed on
-within the following structure.
-
-
-.. code-block:: c
-
- /* pointer to and size of a single iframe in memory */
- struct video_still_picture {
- char *iFrame; /* pointer to a single iframe in memory */
- int32_t size;
- };
-
-
-.. _video_caps:
-
-video capabilities
-==================
-
-A call to VIDEO_GET_CAPABILITIES returns an unsigned integer with the
-following bits set according to the hardwares capabilities.
-
-
-.. code-block:: c
-
- /* bit definitions for capabilities: */
- /* can the hardware decode MPEG1 and/or MPEG2? */
- #define VIDEO_CAP_MPEG1 1
- #define VIDEO_CAP_MPEG2 2
- /* can you send a system and/or program stream to video device?
- (you still have to open the video and the audio device but only
- send the stream to the video device) */
- #define VIDEO_CAP_SYS 4
- #define VIDEO_CAP_PROG 8
- /* can the driver also handle SPU, NAVI and CSS encoded data?
- (CSS API is not present yet) */
- #define VIDEO_CAP_SPU 16
- #define VIDEO_CAP_NAVI 32

+Digital TV Audio Device
+#######################
+
+The Digital TV audio device controls the MPEG2 audio decoder of the Digital
+TV hardware. It can be accessed through ``/dev/dvb/adapter?/audio?``. Data
+types and ioctl definitions can be accessed by including
+``linux/dvb/audio.h`` in your application.
+
+Please note that some Digital TV cards don't have their own MPEG decoder, which
+results in the omission of the audio and video device.
+
+These ioctls were also used by V4L2 to control MPEG decoders implemented
+in V4L2. The use of these ioctls for that purpose has been made obsolete
+and proper V4L2 ioctls or controls have been created to replace that
+functionality.

+Audio Data Types
+****************
+
+This section describes the structures, data types and defines used when
+talking to the audio device.
+
+.. c:type:: audio_stream_source
+
+The audio stream source is set through the AUDIO_SELECT_SOURCE call
+and can take the following values, depending on whether we are replaying
+from an internal (demux) or external (user write) source.
+
+
+.. code-block:: c
+
+ typedef enum {
+ AUDIO_SOURCE_DEMUX,
+ AUDIO_SOURCE_MEMORY
+ } audio_stream_source_t;
+
+AUDIO_SOURCE_DEMUX selects the demultiplexer (fed either by the
+frontend or the DVR device) as the source of the video stream. If
+AUDIO_SOURCE_MEMORY is selected the stream comes from the application
+through the ``write()`` system call.
+
+
+.. c:type:: audio_play_state
+
+The following values can be returned by the AUDIO_GET_STATUS call
+representing the state of audio playback.
+
+
+.. code-block:: c
+
+ typedef enum {
+ AUDIO_STOPPED,
+ AUDIO_PLAYING,
+ AUDIO_PAUSED
+ } audio_play_state_t;
+
+
+.. c:type:: audio_channel_select

+ AUDIO_STEREO,
+ AUDIO_MONO_LEFT,
+ AUDIO_MONO_RIGHT,
+ AUDIO_MONO,
+ AUDIO_STEREO_SWAPPED
+ } audio_channel_select_t;
+
+
+.. c:type:: audio_status
+
+The AUDIO_GET_STATUS call returns the following structure informing
+about various states of the playback operation.
+
+
+.. code-block:: c
+
+ typedef struct audio_status {
+ boolean AV_sync_state;
+ boolean mute_state;
+ audio_play_state_t play_state;

+ audio_channel_select_t channel_select;
+ boolean bypass_mode;
+ audio_mixer_t mixer_state;
+ } audio_status_t;
+
+
+.. c:type:: audio_mixer
+
+The following structure is used by the AUDIO_SET_MIXER call to set the
+audio volume.
+
+

+/* Budgetpatch note:
+ * Original hardware design by Roberto Deza:
+ * There is a DVB_Wiki at
+ * https://linuxtv.org
+ *
+ * New software triggering design by Emard that works on
+ * original Roberto Deza's hardware:
+ *
+ * rps1 code for budgetpatch will copy internal HS event to GPIO3 pin.
+ * GPIO3 is in budget-patch hardware connectd to port B VSYNC
+ * HS is an internal event of 7146, accessible with RPS
+ * and temporarily raised high every n lines
+ * (n in defined in the RPS_THRESH1 counter threshold)
+ * I think HS is raised high on the beginning of the n-th line
+ * and remains high until this n-th line that triggered
+ * it is completely received. When the reception of n-th line
+ * ends, HS is lowered.
+ *
+ * To transmit data over DMA, 7146 needs changing state at
+ * port B VSYNC pin. Any changing of port B VSYNC will
+ * cause some DMA data transfer, with more or less packets loss.
+ * It depends on the phase and frequency of VSYNC and
+ * the way of 7146 is instructed to trigger on port B (defined
+ * in DD1_INIT register, 3rd nibble from the right valid
+ * numbers are 0-7, see datasheet)
+ *
+ * The correct triggering can minimize packet loss,
+ * dvbtraffic should give this stable bandwidths:
+ * 22k transponder = 33814 kbit/s
+ * 27.5k transponder = 38045 kbit/s
+ * by experiment it is found that the best results
+ * (stable bandwidths and almost no packet loss)
+ * are obtained using DD1_INIT triggering number 2
+ * (Va at rising edge of VS Fa = HS x VS-failing forced toggle)
+ * and a VSYNC phase that occurs in the middle of DMA transfer
+ * (about byte 188*512=96256 in the DMA window).
+ *
+ * Phase of HS is still not clear to me how to control,
+ * It just happens to be so. It can be seen if one enables
+ * RPS_IRQ and print Event Counter 1 in vpeirq(). Every
+ * time RPS_INTERRUPT is called, the Event Counter 1 will
+ * increment. That's how the 7146 is programmed to do event
+ * counting in this budget-patch.c
+ * I *think* HPS setting has something to do with the phase
+ * of HS but I can't be 100% sure in that.
+ *
+ * hardware debug note: a working budget card (including budget patch)
+ * with vpeirq() interrupt setup in mode "0x90" (every 64K) will
+ * generate 3 interrupts per 25-Hz DMA frame of 2*188*512 bytes
+ * and that means 3*25=75 Hz of interrupt frequency, as seen by
+ * watch cat /proc/interrupts
+ *
+ * If this frequency is 3x lower (and data received in the DMA
+ * buffer don't start with 0x47, but in the middle of packets,
+ * whose lengths appear to be like 188 292 188 104 etc.
+ * this means VSYNC line is not connected in the hardware.
+ * (check soldering pcb and pins)
+ * The same behaviour of missing VSYNC can be duplicated on budget
+ * cards, by setting DD1_INIT trigger mode 7 in 3rd nibble.

+/* OLD (Original design by Roberto Deza):
+** This code will setup the SAA7146_RPS1 to generate a square
+** wave on GPIO3, changing when a field (TS_HEIGHT/2 "lines" of
+** TS_WIDTH packets) has been acquired on SAA7146_D1B video port;
+** then, this GPIO3 output which is connected to the D1B_VSYNC
+** input, will trigger the acquisition of the alternate field
+** and so on.
+** Currently, the TT_budget / WinTV_Nova cards have two ICs
+** (74HCT4040, LVC74) for the generation of this VSYNC signal,
+** which seems that can be done perfectly without this :-)).
+*/
+
+/* New design (By Emard)
+** this rps1 code will copy internal HS event to GPIO3 pin.
+** GPIO3 is in budget-patch hardware connected to port B VSYNC
+
+** HS is an internal event of 7146, accessible with RPS
+** and temporarily raised high every n lines
+** (n in defined in the RPS_THRESH1 counter threshold)
+** I think HS is raised high on the beginning of the n-th line
+** and remains high until this n-th line that triggered
+** it is completely received. When the reception of n-th line
+** ends, HS is lowered.
+
+** To transmit data over DMA, 7146 needs changing state at
+** port B VSYNC pin. Any changing of port B VSYNC will
+** cause some DMA data transfer, with more or less packets loss.
+** It depends on the phase and frequency of VSYNC and
+** the way of 7146 is instructed to trigger on port B (defined
+** in DD1_INIT register, 3rd nibble from the right valid
+** numbers are 0-7, see datasheet)
+**
+** The correct triggering can minimize packet loss,
+** dvbtraffic should give this stable bandwidths:
+** 22k transponder = 33814 kbit/s
+** 27.5k transponder = 38045 kbit/s
+** by experiment it is found that the best results
+** (stable bandwidths and almost no packet loss)
+** are obtained using DD1_INIT triggering number 2
+** (Va at rising edge of VS Fa = HS x VS-failing forced toggle)
+** and a VSYNC phase that occurs in the middle of DMA transfer
+** (about byte 188*512=96256 in the DMA window).
+**
+** Phase of HS is still not clear to me how to control,
+** It just happens to be so. It can be seen if one enables
+** RPS_IRQ and print Event Counter 1 in vpeirq(). Every
+** time RPS_INTERRUPT is called, the Event Counter 1 will
+** increment. That's how the 7146 is programmed to do event
+** counting in this budget-patch.c
+** I *think* HPS setting has something to do with the phase
+** of HS but I can't be 100% sure in that.
+
+** hardware debug note: a working budget card (including budget patch)
+** with vpeirq() interrupt setup in mode "0x90" (every 64K) will
+** generate 3 interrupts per 25-Hz DMA frame of 2*188*512 bytes
+** and that means 3*25=75 Hz of interrupt frequency, as seen by
+** watch cat /proc/interrupts
+**
+** If this frequency is 3x lower (and data received in the DMA
+** buffer don't start with 0x47, but in the middle of packets,
+** whose lengths appear to be like 188 292 188 104 etc.
+** this means VSYNC line is not connected in the hardware.
+** (check soldering pcb and pins)
+** The same behaviour of missing VSYNC can be duplicated on budget
+** cards, by setting DD1_INIT trigger mode 7 in 3rd nibble.

+
+This system call opens a named video device (e.g.

+
+When an open() call has succeeded, the device will be ready for use. The
+significance of blocking or non-blocking mode is described in the
+documentation for functions where there is a difference. It does not
+affect the semantics of the open() call itself. A device opened in
+blocking mode can later be put into non-blocking mode (and vice versa)
+using the F_SETFL command of the fcntl system call. This is a standard
+system call, documented in the Linux manual page for fcntl. Only one
+user can open the Video Device in O_RDWR mode. All other attempts to
+open the device in this mode will fail, and an error-code will be
+returned. If the Video Device is opened in O_RDONLY mode, the only
+ioctl call that can be used is VIDEO_GET_STATUS. All other call will
+return an error code.

+
+This ioctl is for Digital TV devices only. To control a V4L2 decoder use the

+
+This ioctl call suspends the live video stream being played. Decoding
+and playing are frozen. It is then possible to restart the decoding and
+playing process of the video stream using the VIDEO_CONTINUE command.
+If VIDEO_SOURCE_MEMORY is selected in the ioctl call
+VIDEO_SELECT_SOURCE, the Digital TV subsystem will not decode any more data
+until the ioctl call VIDEO_CONTINUE or VIDEO_PLAY is performed.

+
+This ioctl is for Digital TV devices only. To get events from a V4L2 decoder
+use the V4L2 :ref:`VIDIOC_DQEVENT` ioctl instead.
+
+This ioctl call returns an event of type video_event if available. If
+an event is not available, the behavior depends on whether the device is
+in blocking or non-blocking mode. In the latter case, the call fails
+immediately with errno set to ``EWOULDBLOCK``. In the former case, the call
+blocks until an event becomes available. The standard Linux poll()
+and/or select() system calls can be used with the device file descriptor
+to watch for new events. For select(), the file descriptor should be
+included in the exceptfds argument, and for poll(), POLLPRI should be
+specified as the wake-up condition. Read-only permissions are sufficient
+for this ioctl call.

+#######################
+Digital TV Video Device
+#######################
+
+The Digital TV video device controls the MPEG2 video decoder of the Digital
+TV hardware. It can be accessed through **/dev/dvb/adapter0/video0**. Data
+types and ioctl definitions can be accessed by including
+**linux/dvb/video.h** in your application.
+
+Note that the Digital TV video device only controls decoding of the MPEG video
+stream, not its presentation on the TV or computer screen. On PCs this
+is typically handled by an associated video4linux device, e.g.
+**/dev/video**, which allows scaling and defining output windows.
+
+Some Digital TV cards don't have their own MPEG decoder, which results in the
+omission of the audio and video device as well as the video4linux
+device.
+
+The ioctls that deal with SPUs (sub picture units) and navigation
+packets are only supported on some MPEG decoders made for DVD playback.
+
+These ioctls were also used by V4L2 to control MPEG decoders implemented
+in V4L2. The use of these ioctls for that purpose has been made obsolete
+and proper V4L2 ioctls or controls have been created to replace that
+functionality.

+****************
+Video Data Types
+****************
+
+
+.. _video-format-t:
+
+video_format_t
+==============
+
+The ``video_format_t`` data type defined by
+
+
+.. code-block:: c
+
+ typedef enum {
+ VIDEO_FORMAT_4_3, /* Select 4:3 format */
+ VIDEO_FORMAT_16_9, /* Select 16:9 format. */
+ VIDEO_FORMAT_221_1 /* 2.21:1 */
+ } video_format_t;
+
+is used in the VIDEO_SET_FORMAT function (??) to tell the driver which
+aspect ratio the output hardware (e.g. TV) has. It is also used in the
+data structures video_status (??) returned by VIDEO_GET_STATUS (??)
+and video_event (??) returned by VIDEO_GET_EVENT (??) which report
+about the display format of the current video stream.
+
+
+.. _video-displayformat-t:
+
+video_displayformat_t
+=====================
+
+In case the display format of the video stream and of the display
+hardware differ the application has to specify how to handle the
+cropping of the picture. This can be done using the
+VIDEO_SET_DISPLAY_FORMAT call (??) which accepts
+
+
+.. code-block:: c
+
+ typedef enum {
+ VIDEO_PAN_SCAN, /* use pan and scan format */
+ VIDEO_LETTER_BOX, /* use letterbox format */
+ VIDEO_CENTER_CUT_OUT /* use center cut out format */
+ } video_displayformat_t;
+
+as argument.
+
+
+.. _video-stream-source-t:
+
+video_stream_source_t
+=====================
+
+The video stream source is set through the VIDEO_SELECT_SOURCE call
+and can take the following values, depending on whether we are replaying
+from an internal (demuxer) or external (user write) source.
+
+
+.. code-block:: c
+
+ typedef enum {
+ VIDEO_SOURCE_DEMUX, /* Select the demux as the main source */
+ VIDEO_SOURCE_MEMORY /* If this source is selected, the stream
+ comes from the user through the write
+ system call */
+ } video_stream_source_t;
+
+VIDEO_SOURCE_DEMUX selects the demultiplexer (fed either by the
+frontend or the DVR device) as the source of the video stream. If
+VIDEO_SOURCE_MEMORY is selected the stream comes from the application
+through the **write()** system call.
+
+
+.. _video-play-state-t:
+
+video_play_state_t
+==================
+
+The following values can be returned by the VIDEO_GET_STATUS call
+representing the state of video playback.
+
+
+.. code-block:: c
+
+ typedef enum {
+ VIDEO_STOPPED, /* Video is stopped */
+ VIDEO_PLAYING, /* Video is currently playing */
+ VIDEO_FREEZED /* Video is freezed */
+ } video_play_state_t;
+
+
+.. c:type:: video_command
+
+struct video_command
+====================
+
+The structure must be zeroed before use by the application This ensures
+it can be extended safely in the future.
+
+
+.. code-block:: c
+
+ struct video_command {
+ __u32 cmd;
+ __u32 flags;
+ union {
+ struct {
+ __u64 pts;
+ } stop;
+
+ struct {
+ /* 0 or 1000 specifies normal speed,
+ 1 specifies forward single stepping,
+ -1 specifies backward single stepping,
+ >>1: playback at speed/1000 of the normal speed,
+ <-1: reverse playback at (-speed/1000) of the normal speed. */
+ __s32 speed;
+ __u32 format;
+ } play;
+
+ struct {
+ __u32 data[16];
+ } raw;
+ };
+ };
+
+
+.. _video-size-t:
+
+video_size_t
+============
+
+
+.. code-block:: c
+
+ typedef struct {
+ int w;
+ int h;
+ video_format_t aspect_ratio;
+ } video_size_t;
+
+
+.. c:type:: video_event
+
+struct video_event
+==================
+
+The following is the structure of a video event as it is returned by the
+VIDEO_GET_EVENT call.
+
+
+.. code-block:: c
+
+ struct video_event {
+ __s32 type;
+ #define VIDEO_EVENT_SIZE_CHANGED 1
+ #define VIDEO_EVENT_FRAME_RATE_CHANGED 2
+ #define VIDEO_EVENT_DECODER_STOPPED 3
+ #define VIDEO_EVENT_VSYNC 4
+ long timestamp;
+ union {
+ video_size_t size;
+ unsigned int frame_rate; /* in frames per 1000sec */
+ unsigned char vsync_field; /* unknown/odd/even/progressive */
+ } u;
+ };
+
+
+.. c:type:: video_status
+
+struct video_status
+===================
+
+The VIDEO_GET_STATUS call returns the following structure informing
+about various states of the playback operation.
+
+
+.. code-block:: c
+
+ struct video_status {
+ int video_blank; /* blank video on freeze? */
+ video_play_state_t play_state; /* current state of playback */
+ video_stream_source_t stream_source; /* current source (demux/memory) */
+ video_format_t video_format; /* current aspect ratio of stream */
+ video_displayformat_t display_format;/* selected cropping mode */
+ };
+
+If video_blank is set video will be blanked out if the channel is
+changed or if playback is stopped. Otherwise, the last picture will be
+displayed. play_state indicates if the video is currently frozen,
+stopped, or being played back. The stream_source corresponds to the
+selected source for the video stream. It can come either from the
+demultiplexer or from memory. The video_format indicates the aspect
+ratio (one of 4:3 or 16:9) of the currently played video stream.
+Finally, display_format corresponds to the selected cropping mode in
+case the source video format is not the same as the format of the output
+device.
+
+
+.. c:type:: video_still_picture
+
+struct video_still_picture
+==========================
+
+An I-frame displayed via the VIDEO_STILLPICTURE call is passed on
+within the following structure.
+
+
+.. code-block:: c
+
+ /* pointer to and size of a single iframe in memory */
+ struct video_still_picture {
+ char *iFrame; /* pointer to a single iframe in memory */
+ int32_t size;
+ };
+
+
+.. _video_caps:
+
+video capabilities
+==================
+
+A call to VIDEO_GET_CAPABILITIES returns an unsigned integer with the
+following bits set according to the hardwares capabilities.
+
+
+.. code-block:: c
+
+ /* bit definitions for capabilities: */
+ /* can the hardware decode MPEG1 and/or MPEG2? */
+ #define VIDEO_CAP_MPEG1 1
+ #define VIDEO_CAP_MPEG2 2
