[FFmpeg-devel] [PATCH v12 0/9] DNxUncompressed decoder

[Martin Schitter]

This is a reworked 11th version of my DNxUncompressed decoder contribution.

I added many new pixel formats and swscale input support variants for all
those payload types that do not need any format specific unpacking.

Most pixel format variants found in the specification are now supported.
Unfortunately I don't have samples to test all of them.
At least all export options supported by DaVinci Resolve should work.

Combined Components and mixed RGB + Alpha content is still not supported.

Please check the code and merge it.
