[FFmpeg-user] Problems with concat demuxer

[Gabriele Greco]

I have some problems with concat demuxer when the input files has audio
encoded as "pcm_bluray", the output file ends up with a "bin_data" stream
that ffmpeg itself does not recognise.

(I used master version updated just before writing this e-mail)

Here is what I get when I clone this MTS file (that can be recognised
without problems by ffmpeg and played by VLC and by my avcodec based
player):
