From: Andriy Gelman <andriy.gel...@gmail.com> V4L2 api can indicate that flushing of the capture buffers is completed by setting the V4L2_BUF_FLAG_LAST flag. Use guards because the flag was only defined in Linux v4.2.
Reference: linux/Documentation/media/uapi/v4l/dev-decoder.rst "The client must continue to handle both queues independently, similarly to normal decode operation. This includes: ... - queuing and dequeuing CAPTURE buffers, until a buffer marked with the V4L2_BUF_FLAG_LAST flag is dequeued" Signed-off-by: Andriy Gelman <andriy.gel...@gmail.com> --- libavcodec/v4l2_context.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/libavcodec/v4l2_context.c b/libavcodec/v4l2_context.c index f0ecc18ebd..da802405e4 100644 --- a/libavcodec/v4l2_context.c +++ b/libavcodec/v4l2_context.c @@ -400,6 +400,10 @@ dequeue: ctx->done = 1; return NULL; } +#ifdef V4L2_BUF_FLAG_LAST + if (buf.flags & V4L2_BUF_FLAG_LAST) + ctx->done = 1; +#endif } avbuf = &ctx->buffers[buf.index]; -- 2.25.1 _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
