[FFmpeg-devel] [PATCH] Add enable_keyframe_filtering option for libaom-av1 encoder.

[Bohan Li]

Hi Jan,

Thanks for the suggestion! I believe that is a good idea. I am not super
familiar with this part, though, so will probably need to propose this to
the Aomedia issue tracker.
Meanwhile I think it is also useful to expose useful options (like this
one, enable-keyframe-filtering, which is discussed quite a few times in the
community as far as I know) to the users as well. So I think we should
still apply this patch, and if once the mentioned API is working, we could
maybe re-consider which ones are more needed.

Best,
Bohan
