[FFmpeg-devel] [PATCH 1/3] libavfilter/scale2ref: Add constants for the non-ref input

[Kevin Mark]

Thank you, I was not aware there was a ticket already for this issue. I
wouldn't be comfortable calling this a bug fix (or that ticket being a
bug/defect) considering the current functionality, while not particularly
intuitive, is consistent with the documentation. Patch 3 helps clarify the
scale2ref documentation a tad but there's still more room to clarify the
wording, no doubt. It's not explicit that "as basis" means all the scale
variables will be set to that of the reference input. I'll consider
submitting another patch for that after this is applied/discussed.
