Hi Carl,

I'd be glad to test this, but I'm no exactly sure how to do this.  Do I
just replace the code from this git commit:
with the code at the same location in ffmpeg_opts.c ?  Do I need to
recompile afterward?

Or if none of the above, could you point me to some resource so that I can
learn the procedure?
