2 years ago - nvenc/h265 tested on Linux and windows
- msdk h264/5 tested (included because way better quality than VAAPI on Intel)

2 years ago Do you have access to these encoders and did you test them? Just wondering whether gop-size is really being used on both since they usually don't share the same names for their options.

2 years ago At least gop-size is mentioned by gst-inspect-1.0 as an element property for msdk. It could be there for compatibility reasons though.
