Well, the check's been in there for quite a while; that's not new.
(isPlanarYUV(pix_fmt) && desc->comp[1].plane == desc->comp[2].plane);
So, any planar yuv format where component 1 and component 2 are on the
same plane. Except for semi planar formats, you expect either all
components on the same plane (packed, so not planar) or every
component
on a separate plain (normal planar).
Yes, I understand that. I mean: can you list all formats that function
matches?
For formats that swscale understands:
NV12, NV21
P010(BE|LE)
P016(BE|LE)
and now NV24, NV42.
There are also NV16 and NV20(BE|LE) formats which are not supported by
swscale.
