can't detect lpcm in ts?

~18 mb sample I made with (hacked) ffmpeg 4.4 with backported bluray-pcm encoder from ffmpeg git.

May be I did it wrong, but at least mplayer plays it...

fixed in ffmpeg git... sorry, really not your bug

[jcdr428]

@Randrianasulu so no more issue in tsMuxer with the commit in ffmpeg.git ?

[Randrianasulu]

yeah, it works - tsmuxer recognizes stream and xine can play (renamed) iso...
