When you concatenate (with concat demuxer) matroska files which were
created by ffmpeg in streaming mode (i.e. written to non-seekable file),
it fails.
The error is this:
{{{
[concat @ 0x3dfa1a0] file:1 stream:0 pts:0 pts_time:0 dts:NOPTS
dts_time:NOPTS -> pts:-9223372036854776 pts_time:-9.22337e+12 dts:NOPTS

[matroska @ 0x3e33f80] Timestamps are unset in a packet for stream 0. This
is deprecated and will stop working in the future. Fix your code to set
the timestamps properly
[matroska @ 0x3e33f80] Starting new cluster at offset 8519 bytes, pts

[matroska @ 0x3e33f80] Can't write packet with unknown timestamp
av_interleaved_write_frame(): Invalid argument
}}}
How could this be worked around in concat demuxer? How is it supposed to
be worked around in any libavformat application? As far as I rememeber
matroska always used to have such NOPTS frames.
How to reproduce (https://gist.github.com/andrey-
utkin/d24f2fa744bd18a2067a):
{{{
ffmpeg -loglevel debug -f lavfi -i testsrc -t 1 -vcodec libx264 -f
matroska - >1.mkv
ffmpeg -loglevel debug -f lavfi -i testsrc -t 1 -vcodec libx264 -f
matroska - >2.mkv
echo "ffconcat version 1.0
file 1.mkv
file 2.mkv
" > clips.concat
ffmpeg -loglevel debug -f concat -i clips.concat -c copy -y concat.mkv
}}}
