Reading Dolby Vision RPU from m2ts #401

Closed YomikoR closed 2 years ago

YomikoR commented 2 years ago

I built FFMS2 on Windows with FFmpeg 5.0.1 for the latest feature in master. When indexing a blu-ray m2ts with DV profile 7, FFMS2 adds global parameters to frame properties but not the frame-dependent DolbyVisionRPU. unknown Things work as expected if indexing the output of MakeMKV instead. unknown (Same frame in my previewer btw)

I think MakeMKV may be merging the MEL/EL and base layer - IIRC UHD Blu-rays have their RPUs in a separate stream (the MEL/EL stream), so opening the m2ts directly with FFMS2 would require you to use that stream to get the RPUs.

Yes, with m2ts you have to use the second video track. I don't know if the plugin allows track selection.

If it does, then you only have to copy the prop over to the first video stream clip.

Thanks. The data can be found with track=1.
