Super hacky workaround enabling blackmagic raw decode support into ffmpeg based on the reverse engineered 2019 implementation patch floating around, compiled and merged to form a working codebase; the caveat is the 2019 patch is semi broken with the output being super dark and green tinted; looks very similar to a problem Magic Lantern had a while back (something about the rggb16le using 12bits in a 16 bit container maybe?).

So to duct tape a solution I just added a bunch of filters and offsets to the output pipeline and a custom gamma curve to approximate gen 5 color science. These are the commands I used with differing r,g,and b values based on the color temp and tint:

./ffmpeg -i /mnt/l/input.braw -vf colorchannelmixer=rr=0.98:gg=0.62:bb=0.8,tonemap=linear:param=300,tonemap=gamma:param=1.4,curves=psfile='BRAWHLRolloff.acv' -acodec aac -vcodec prores_ks -pix_fmt yuv444p outputProRes.mov

./ffmpeg -i /mnt/i/input.braw -vf colorchannelmixer=rr=0.78:gg=0.58:bb=0.86,tonemap=linear:param=300,tonemap=gamma:param=1.38,curves=psfile='BRAWHLRolloff.acv' -acodec aac -vcodec prores_ks -pix_fmt yuv444p outputProRes.mov

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

• libavcodec provides implementation of a wider range of codecs.
• libavformat implements streaming protocols, container formats and basic I/O access.
• libavutil includes hashers, decompressors and miscellaneous utility functions.
• libavfilter provides a mean to alter decoded Audio and Video through chain of filters.
• libavdevice provides an abstraction to access capture and playback devices.
• libswresample implements audio mixing and resampling routines.
• libswscale implements color conversion and scaling routines.

• ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
• ffplay is a minimalistic multimedia player.
• ffprobe is a simple analysis tool to inspect multimedia content.
• Additional small tools such as aviocat, ismindex and qt-faststart.
