I managed to make video with amr_nb codec in openCamera (android 11)
mediainfo /dev/shm/VID_20240215_064913.mp4
General
Complete name: /dev/shm/VID_20240215_064913.mp4
Format : MPEG-4
Format profile :
I was looking into https://trac.ffmpeg.org/ticket/1258#comment:12
(mpeg2 multichannel audio in HDV) and reading documents linked in
this ticket.
I still have very vague understanding on where ffmpeg audio (PES?)
headers read by ffmpeg
somewhere in ffmpeg/libavformat/mpeg.c ?

According to this source (vlc) lpcm dvd audio supports lower frequencies
like 44100/32000 hz - useful for direct dv transcoding for example
https://github.com/videolan/vlc/blob/master/modules/codec/lpcm.c

Does this mean that libavcodec/pcm-dvdenc.c can be trivially

well, there
For announcement writer(s) - can you please at least list API changes with
pointer to documentation section?
As someone who tries to co-maintain software (cinelerra-gg) relying on
ffmpeg AND other libraries fishing out changes and examples out of git log
exhaust me and makes me sad.

well, I am not sure if anything can pull 2000 filters ON TOP of each other

but applying dynamic
FFmpeg today support some opencl filters (but I was unable to use them
freely in Cinelerra-gg probably because they require not just
initialization of hw device but also manual up and download of data ...)
but I wonder if same opencl infra can be used in decoders and encoders too?
