[FFmpeg-user] Transcode 5.1 Flac to 5.1 LPCM in ffmpeg

[Zamar Acadia]

Thanks Carl,

Here is the printout. You said ffmpeg doesn't support encoding Bluray PCM,  
but there seems to be such codec included below? Which codec should I  
choose to transcode 5.1 Flac to 5.1 LPCM audio in ffmpeg, and how the  
command line would look like?

If none, what these PCM codecs are for - any link with description? What  
other program would someone suggest for the task? I tried eac3to, but the  
resulting file can't play on any player supporting LPCM playback like Daum  
Potplayer or VLC, despite it can be imported and play correctly in  
Audacity. Probably, the header is wrong. FFPlay says: "Invalid data found  
when processing input".

Also, what media info program can decipher media info from multichannel  
LPCM file? I tried MediaInfo and Gspot with no success.  FFMpeg -i gives  
the same above error.
