Screen Recording Issues

I've used both simplescreenrecorder and recordMyDesktop. I'm using MATE display manager using Gala window manager. When I record my desktop, the output is a black screen, however, the mouse is rendered.

When I run 'marco --replace' to swap back to marco rather than gala, it records fine. I don't mind swapping just to do screen casts, but I would like to show off my system when recording rather than having to move to a fallback.

Any ideas?

Extra Info: I am using the AMD catalyst drivers, not the ATI alternative.

Re: Screen Recording Issues

If you're going to use compositing in your WM, you need to turn flipping off (video driver settings, to avoid flickering window effects) and you also might need to turn off indirect rendering in your WM for better results (compiz can do that, don't know about Gala).

I didn't get the two tools you mentioned to work well either, as an alternative I've been using ffmpeg's x11grab feature:

ffmpeg -f x11grab -s 1920x1080 -i :0.0+0,0 out_video.avi

Might need some fiddling to get audio working, this one works fine for me

ffmpeg -f alsa -i pulse -f x11grab -s 1920x1080 -i :0.0+0,0 -strict -2 output.avi

( which audio to record can be changed with pavuconstrol, I used the monitor for the combined sink. The audio stream might needs to be active though or ffmpeg will halt & wait for it )

This is the least buggy solution I found. Also lets you can encode / start uploading / watch the video (for weird mirror effect ) while you're still recording and is easier to start than most GUI tools once you're set up.

Re: Screen Recording Issues

recordMyDesktop is useless. For SSR: Did you try to capture OpenGL, because that will not work most of the time.
