Further fuzzing has found more problems in ffmpeg code. I have opened
two tickets:
https://trac.ffmpeg.org/ticket/11344
https://trac.ffmpeg.org/ticket/11345
No problems have been found in my changes.
Does this mean I have done sufficient testing to have my changes approved?
I asked for guidance
Fuzzing has discovered one crash bug so far. It's not related to my
changes.
The crash has some potential to be exploitable so I've emailed
ffmpeg-secur...@ffmpeg.org. Email includes a sample and repro
instructions.

Hi all - what do I need to do to progress this?
I'm not sure, but it sounds like Tomas thought patch 1 might need
someone with experience with Bayer taking a look.
Thanks

ffmpeg has existing support for MLV raw video files; libavformat/mlvdec.c.
Since this was added, MLV has been extended to support LJ92 compressed
image data. These patches build on lossless DNG support in 7.2-dev to
enable handling LJ92 MLV via existing libavcodec/mjpegdec.c code.
Sample LJ92 MLV
that only happens when
we're confident the pix_fmt is Bayer.
