Was looking for xing media software, found this little open-source utility
printing info on mpeg audio files, including this rare multichannel
extension!

just found this accidently

but commit history says it only works on Windows (where other DCC tools

after installing mctoolame and pcm2aiff from iso-dist10 (also on my
github) I can run such line:
encode2mpeg -svcd -mp2 mctoolame -mpegchannels 6 -n p -imageonly
/dev/shm/matrixbench_highdivx_ac3.avi -o /dev/shm/svcd_test.iso

Header: it seems that default mplex can mux 3 min test multichannel
mpeg audio (mp2) audio just fine ...

so I basically did DVD with cinelerra-gg from matrixbench clip (w/ ac3
sound from samples .mplayerhq.hu)
then I rendered out audio
Not really full patch, but just something I hacked together for
compiling cinelerra-gg on termux (linux terminal emulator AND
distribution for running on Android 7+ devices).
I wonder if this functionality can be (or should) be rolled into
mjpegtools ? Or it better remain as separate patch for
So, I was having a blast hacking old en/decoder.
My own hacks do not work on 64-bit yet (they run, just sounds wrongs
:) ) but this one was tested on aarch64 Termux install, so should be
better

According to this source (vlc) lpcm dvd audio supports lower frequencies
like 44100/32000 hz - useful for direct dv transcoding for example

see lines 524, 608
Does this mean that libavcodec/pcm-dvdenc.c can be trivially
Hello!
I am trying to develop procedure for making DVDs with LPCM audio using
Linux NLE Cinelerra-gg [1]
