[FFmpeg-devel] [PATCH 6/6] avcodec: add vvdec H.266/VVC decoder

[Nuo Mi]

Hi Chen,
Glad you can try it.

Since hevc, the interlaced encoder is not supported.
Encoder always encoder a frame, use an SEI to tell the user it's top/bottom
filed or it's a frame.
It's named Adaptive Frame Field (SAFF).
Current ffmpeg can't support this very well for even hevc, I think we can
put this later.
