[FFmpeg-devel] [PATCH 5/5] kmsgrab: Add more supported formats

Mark Thompson sw at jkqxz.net
Sat Aug 1 20:57:35 EEST 2020


X2RGB10 tested on both Intel Gen9 and AMD Polaris 11.  NV12 tested on
Intel Gen9 only - since it has multiple planes, this requires GetFB2.

Also add some comments to split the list up a bit.
