Allow recording a region by recording the compositor proxy window / nvfbc window and copying part of it.
|
||||
Use nvenc directly, which allows removing the use of cuda.
|
||||
Handle xrandr monitor change in nvfbc.
|
||||
Add option for yuv 4:4:4 chroma sampling for the output video.
|
||||
Implement follow focused in drm.
|
||||
Support fullscreen capture on amd/intel using external kms process.
|

Support amf and qsv.

||||
Set audio track name to audio device name (if not merge of multiple audio devices).
|
||||
Add support for webcam, but only really for amd/intel because amd/intel can get drm fd access to webcam, nvidia cant. This allows us to create an opengl texture directly from the webcam fd for optimal performance.
|
||||
Reverse engineer nvapi so we can disable "force p2 state" on linux too (nvapi profile api with the settings id 0x50166c5e).
|
||||
Support yuv444p on amd/intel.
|
||||
fix yuv444 for hevc.
|
||||
Do not allow streaming if yuv444.
|
||||
Support 10 bit output because of better gradients. May even be smaller file size.
