Subject: media: coda: only set the stream end flags if there are no more pending output buffers Author: Philipp Zabel <[email protected]> Date: Tue Jun 18 12:45:25 2019 -0400 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.
