[FFmpeg-devel] [PATCH 0/3] avformat: Use s337m subdemux inside mxf/wav

[Nicolas Gaullier]

In case of an mxf or wav file having stereo tracks, the new 'dolbyeprobe' flag
enables detection of dolby_e.
The probing is done on the first sample and its guard band must be clean (to avoid wrong detection).

Tests samples for fate-suite/dolby_e uploaded here:

Thank you for the review
