DVD subtitle palette is YUV. However, when stored in modern formats such as
matroska or MP4, the "convention" is to store in RGB.
In fact, mp4/mov muxer has a similar routine.

Hi Leo,
Thank you for the feedback and review. I will work through the code style
issues. Please do let me know what else you find - I will fix.
Here is some responses on the conceptual issues,

Make sure when you generate the second version of a patch with git
format-patch you pass the -v2 argument, e.g.
git format-patch -v2 -o outgoing/ master
Otherwise
This confused me for a long time, hopefully this is helpful to others.
The definition in avformat.h says "Ignore DTS on frames that contain both DTS &
PTS"

With the way the runtime checks are currently set up, every single
openh264 release, no matter how minor, is considered an ABI break and
requires ffmpeg recompilation. This is unnecessarily strict because it
doesn't allow downstream distributions to ship any openh264 bug fix
version updates
