Haven't had time to bisect, but I can't screengrab to mkv any more.
kmsgrab + playing with vsync etc. give the same error as this example,
mp4 works OK.
ffm -loglevel debug -vaapi_device /dev/dri/renderD128 -f x11grab
-video_size 1920x1080 -i :0 -vf 'format=nv12,hwupload' -c:v h264_vaapi
I would like to know how to perform smooth and continuous transmissions,
that is, I would like ffmpeg to allow connections even if it has no
currents, I would also like to be able to indicate new video entries that
are transmitted one after another without stopping the server, I do not
want to use
