I can't concat 2 mkv files.

[Ivan]

Summary of the bug:
I can't concat 2 mkv files.
How to reproduce:

% ffmpeg -i "concat:1.mkv|0.mkv" -y -c copy concat.mkv

I have to transform them to mpeg-ts and then back to mkv

ffmpeg -i 0.mkv -y -an -vcodec copy 0.ts
ffmpeg -i 1.mkv -y -an -vcodec copy 1.ts
ffmpeg -i "concat:0.ts|1.ts" -y -an -vcodec copy concat.mkv

The concat protocol cannot work for all file formats, use the concat filter or the concat demuxer.
