Mplayer doesn't detect PCM in ts/m2ts

[qkthr]

I'm looking to convert a BR to a 720 mkv, while keeping the audio lossless.

I've extracted the video and PCM audio streams into a single .ts file for experimenting with, as I couldn't get mplayer to detect the PCM stream from the m2ts.

So, I have a file: track_4113.264.ts

ffmpeg reports both streams:

Why can't mplayer see Stream #0.1[0x1100](eng): Audio: pcm_bluray, 48000 Hz, 5.1, s32, 6912 kb/s that ffmpeg sees?

mplayer detects this exact audio stream fine if it's just inside a wav:

I'm sure there's something simple here that I'm not doing..... any ideas?

Cheers!!

Probably going to require eac3to . I don't know enough about the app, but if you just want to play your file I'd tell eac3to to convert the 6 channel PCM to 5.1 AC3.

Got it sorted

I just needed to pass in - -demuxer lavf (referenced in a similar problem, http://lists.mplayerhq.hu/pipermail/mplayer-users/2009-July/077284.html)
