Hi,
I'm trying to index the BlackMagic Raw Codec, which basically is a lossy video codec with PCM audio muxed in ".braw".
Inside the .braw, I can see a PCM audio file and a brlt video file which is supposed to be a 4K file shot in RGB, log as color curve, 12bit, at 23.976fps.

Using MKVMerge (MKVToolnix) I managed to remux it to .mkv

however when I tried to extract the video stream only with MKVExtract it failed:

I tried to index both the remuxed mkv and the original .braw file and both ffms2 and LWLibav I tried to DirectShowSource as well, but I don't have any codec for .braw files, so it clearly failed to open it (just like MPC-HC, PotPlayer and MPV):

I tried with ffplay.exe with the latest build ffmpeg-20190411-3e10223 but it failed:

Of course, I could just use their proprietary player and play it and I can also import the files in Davinci Resolve and export them, but I was wondering whether there's support for Avisynth or ffmpeg.
This is their SDK, so it shouldn't be so hard to make a decoder in the future: Link (https://www.blackmagicdesign.com/uk/support/latest-download/braw-sdk/windows)
Thank you in advance,
