Screen recorder - jiyong - 02-23-2020
I am trying to record the screen of the Pinebook Pro with audio from the webcam mic.
I tried Kazam, but it can only record in AVI (huge file and audio died after 30 seconds!) and not with h264.
I'm testing with FFMPEG, but I get audio drops and the image quality is not what I hoped for.
This is the command I'm using at the moment:
ffmpeg -video_size 1920x1080 -framerate 30 -f x11grab -i :0.0 -vcodec libx264 -c:v h264_rkmpp -thread_queue_size 32 -f alsa -ac 2 -i hw:0 output.mkv
Anyone has a working solution for recording the screen, or knows how to tweak FFMPEG?
I also installed the package x264 from the Synaptic Package Manager.

I was watching a Youtube video from LearnLinuxTV and I noticed he used SimpleScreenRecorder.
That one gives a decent result.
It reports around 13 fps, so I guess 30 fps isn't possible, until we get hardware encoding running.

ffmpeg can also do it, see x11grab in the man page. Not exactly a GUI user-friendly program but I've done it a couple times. You can grab just part of the screen I think. But computer screens with mostly low numbers of colors and sharp contrasts don't work well with mpeg which is a little like jpeg that way.
