Description
Summary of the bug:
Muxing two working files (AC3 stream + DVD sub stream and a freshly encoded ffv1 stream) into a mkv produces a broken file: seeking around can break (mute) audio.
Reproducible with both mpv and ffplay (example: seek to around 5.5s).
It seem like http://ffmpeg.gusari.org/viewtopic.php?f=11&t=2713 is related.
On the longer sample, I also get:
-Audio being muted without having to seek
-"Starting new cluster due to timestamp" matroska warnings during mux
-"[mkv] Too many packets in the demuxer packet queues" errors in mpv
How to reproduce:
ffmpeg -y -i 20s.mkv -i ffv1.mkv -map 0:a:1 -map 0:s -map 1:v -c copy out.mkv >ffmpeg.log 2>&1

Yes, I tried with the Van Sickle git build. Also, mkvtoolnix (9.6.0) produces a valid result.
comment:4 by , 7 years ago
Could you explain how I can reproduce the issue?
I downloaded the two samples, used your exact command line and played the output file with ffplay: No matter how often I seek, sound always plays fine.
comment:5 by , 7 years ago
I gave an example because of size of the sample. Seek around 5.5s and there's no sound.
comment:6 by , 7 years ago
This is actually exactly like the link said.
ffmpeg -i 20s.mkv -map 0:v:0 -c:v ffv1 ffv1.mkv ffmpeg -i 20s.mkv -i ffv1.mkv -map 0:a -map 0:s -map 1:v -c copy out.mkv ffmpeg -i 20s.mkv -c:a copy -c:s copy -c:v ffv1 out2.mkv
out.mkv fails while out2.mkv works; when the operation is fundamentally the same.

Regression since 3adb5f8d / d9ae1031
Note that ticket #429 to which this is related was not reproducible with 6a4cc509.
comment:8 by , 7 years ago
Hello, is there any progress on this? Maybe the title or something should be
changed since the problem isn't mkv muxing by itself, but using multiple sources
instead of one. The URL I gave in the OP is clearer than me.

- This is similar to #7064; but it is not a duplicate (this issue happens because the second input file isn't read at all until the first file has been completely read because no subtitle packet has been found in the first; in #7064 the problem is that the external subtitle files are immediately available and increase the length of the muxing queue beyond what is permitted by max_interleave_delta, forcing output of packets which results in suboptimal interleavement).
- It has indeed nothing to do with mkv muxing; the problem can also be seen with e.g the framehash muxer alone. Here is a shortened output of the framehash muxer:

- The url in the OP doesn't work anymore, but it's available via archive.org. It's not very enlightning.
- The subtitle track from file 20s.mkv that is to be merged doesn't contain any packets. Here is what happens because of that:

To sum it up:
a) The first input file is read; a few audio packets are demuxed, but no subtitle packet is found. Therefore it continues to read this file until the delay between the first and the last packet in the muxing queue is bigger than 10s. As soon as this happens, a packet of the audio track is output (so that the delay between the first and the last packet in the muxing queue is below 10s again). After that 20s.mkv is read again (probably because no subtitle packet has been found) and a new audio frame is demuxed, making the delay between the first and the last packet in the muxing queue longer than 10s again and forcing the output of another audio packet. This goes on until 20s.mkv has been completely consumed. The last audio packet of the audio track that is to be muxed has a timestamp of 19.995s in the input file, for some reason the demuxer applies an offset of -16ms making it 19.979. Accordingly the last packet to be output at this stage has an (output) timestamp of 9963ms.
b) After a) the muxing queue is almost 10s long and its highest timestamp is 19979ms. Now ffv1.mkv is read. The first packet has a timestamp of 0 and is automatically output because the muxing queue length is longer than 10s after said packet has been added to it. This goes on until the length of the muxing queue is less than 10s (the last video packet whose output is forced has a timestamp of 9960ms; the next timestamp is 9980ms).
c) Then the length of the muxing queue is less than 10s and the rest of the output packets are interleaved properly.

MKV muxing is "not broken" ? - that is bullshit.
try codec copy in any random combination to mkv destination...

also had just run into this problem by using a input mkv with video and audio stream and replacing that audio with a external track (even if it is literally the same audio stream extracted into its own file), using "-max_interleave_delta 0" fixed it for me
