Hi, I'm working on adding support for HEVC 4:2:2/ 4:4:4, 8/10 bit, in vaapi decoding. And I'm aslo thinking of add some new pix_fmt for packed FourCC: 444 8 bit : AYUV 444 10 bit: Y410 422 10 bit: Y210 So if I'd like to add these new pix_fmts, some modification is necessary too as far as I got from relevant threads: 1. add support in swscale for being able to convert to and from a format, including up and down scale; 2. add test.(maybe a query is needed too) 3. bump a new minor version. Any other concerns should be followed? I'm trying to make sure I understood this correctly. Thanks in advance.
