I wouldn't be surprised if the xlib code has some PTS issues and schedules
downloading a frame late.
I'm far from being an expert, but I would be surprised if that had issues
considering it's the main Linux screen capture we have?
The xcb calls to grab a frame are quite simple/straightforward (both shm and
non shm versions).
The avdevice polls to get new frames. If it polls too late, it will miss a
frame. I think that's where a possible issue is.
This is a good point. As far as I see I can greatly improve the smoothness
of captured frames of xcbgrab by changing the av_usleep(delay) line in
xcbgrab.c to av_usleep(delay/2).
