Sorry, I'm not sure how I missed this one...

The patch looks good to me.

Are there any potential issues with this if the chosen pix_fmt's bpp
is greater than bits_per_raw_sample? I don't know if you should set it
to comps.prec or sum the precision of the comps. The docs on
bits_per_raw_sample make it sound like it's the number of bits in a
single pixel (implies summing precision of comps) but ffv1.c certainly
doesn't use it like this. I trust you or someone else will know better
than me what to do with this.
