From a02f6ca3367e1fd3cbd14e8798af90b8b667bbbe Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Tue, 18 Jun 2019 12:45:25 -0400 Subject: [PATCH] media: coda: only set the stream end flags if there are no more pending output buffers If there are still queued output buffers pending to be copied into the bitstream ring buffer, setting the stream end flag should be deferred until the marked last output buffer is written into the bitstream ring buffer.
