Changes the results of the following tests: - matroska-flac-extradata-update The test reencodes two input FLAC streams into three output FLAC streams. The last output stream is limited to 8 frames. The current code results in the first two output streams having 12 frames, after this commit all three streams have 8 frames and are the same length. This new result is better, since it is predictable. - mkv-1242 The test streamcopies one video and one audio stream, video is limited to 11 frames. The new result shortens the audio stream so that it is not longer than the video. --- fftools/ffmpeg.c | 6 ------ fftools/ffmpeg_mux.c | 10 +--------- fftools/ffmpeg_opt.c | 18 +++++++++++++++--- fftools/sync_queue.c | 13 +++++++++++++ fftools/sync_queue.h | 7 +++++++ tests/ref/fate/matroska-flac-extradata-update | 16 +++++----------- tests/ref/fate/mkv-1242 | 3 --- 7 files changed, 41 insertions(+), 32 deletions(-) diff --git a/fftools/ffmpeg.c b/fftools/ffmpeg.c index 8674f52047..e46554ddf4 100644 --- a/fftools/ffmpeg.c +++ b/fftools/ffmpeg.c @@ -3412,12 +3412,6 @@ static int need_output(void) if (ost->finished || of_finished(of)) continue;
