[FFmpeg-devel] [PATCH v4 0/9] avformat: wav-s337m support + new probe_stream option

[Nicolas Gaullier]

Because of the dependencies, I had to group all the patchs in a serie, but they are 3 functionnal parts :
* patch 1 is necessary to fix dolby_e pts that will be part of the test in patch 8
* patch 2,3,4,5,6,7,8 : s337m support in wav
    this is a rework of a precedent serie (https://patchwork.ffmpeg.org/project/ffmpeg/list/?series=106)
* patch 9 : AVOption to disable codec auto-detect : it seems it is a general request from many users, and it
is also critical here for dolby_e as many broadcasters will still need to just pass-through dolby_e data as they already do.
Thus, the patchset 2,3,4,5,6,7 should not be applied without the last patch 9 applied quickly behind...

Here are the updates on the s337m serie since the last revision:
* an error message has been removed in s337m_get_offset_and_codec because it could never be seen in the actual implementation and thus seemed useless
* the decoding test has been replaced by a demuxing test (Tomas review)

The test sample 512.wav can be downloaded here :

Thank you for the review!
