Re: .cube lut problem

This is both EXR decoder (which does not decode to float) and lut3d filter (which does not work with floats) problem, and is caused by whites/blacks being out of [0 - 1] range.

Re: ffmpeg errors when using ShareX

Do not use mp4 at all. It is bad container as you found out.
It writes crucial info at end of file, and when error happens that info is not provided, resulting in broken file.

Re: Can FFmpeg be used in bare-metal embedded?

FFmpeg as utility needs file system.
On other hand FFmpeg libav* libs do not depend on it so everything can be handled in memory.
