well, but mpv (and vlc?) supports it ....

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

Does this mean that libavcodec/pcm-dvdenc.c can be trivially extended to support those ?
Same question for mplex. (it only supports 48/96 khz lpcm audio).
I also found this table via mjpeg-users archives:
https://dvd.sourceforge.net/dvdinfo/lpcm.html
it lists dynamic range/gain (?) setting equations.
Not mplex nor ffmpeg support setting this to anything but hardcoded 0x80
This might be source of my "too loud" lpcm dvd experiments because I was making lpcm file via cinelerra-gg's raw pcm output format (using libsndfile internally). _______________________________________________ ffmpeg-user mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-user
