[FFmpeg-devel] [PATCH 0/9] avformat: Use s337m subdemux inside wav

[Nicolas Gaullier]

This is a new version of my previous patchset reviewed by Tomas.
http://ffmpeg.org/pipermail/ffmpeg-devel/2019-August/247677.html

It takes into account the last feedback from Carl Eugen,
I mean that the integration of s337m in wav is now similar to the existing one for spdif,
main differences remains that :
- s337m is not enabled by default (activated by the 'dolbyeprobe' AVOption)
- container bit resolution is checked (DolbyE stream bit resolution = WAV PCM bit resolution)
- takes data_end into account (see my latest patch here below: 'Fix s337m last packet parsing'),
but this one could also be 'forwarded' to spdif
- verbose detection and phase (I think it is a broadcast requirement)

Fate samples can be found here:
- 512.wav : http://0x0.st/zdW-.wav
- 512.mxf.pcm : http://0x0.st/zdWo.pcm

Thank you for this new review...
