Canno't record fullscreen games

Gumboherpy · 04-16-2013, 09:20 PM

I want to record myself recording World of Padman through Desura, I use ffmpeg through the commandline to record my desktop, this is the command I use.

Code:

ffmpeg -f x11grab -s `xdpyinfo | grep 'dimensions:'|awk '{print $2}'` -r 25 -i :0.0 -sameq output.mkv

But when I launch the game it stops and I get this error.

Code:

X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  139 (MIT-SHM)
  Minor opcode of failed request:  4 (X_ShmGetImage)
  Serial number of failed request:  269
  Current serial number in output stream:  269

Any ideas as to what is going on?

What does the command

Code:

grep SHM /var/log/Xorg.0.log

give you?

If you don't see

Code:

Initializing built-in extension MIT-SHM

then that's part of the problem.

[    55.623] (II) Initializing built-in extension MIT-SHM

IT shows up.

It's definitely possible. I had a script once upon a time where I could record my desktop playing SCII in wine and stream it to justin.tv.

I have lost the script but it was made after fiddling with the suggestions in these threads..

Found a work around. I use glc which is the fraps for linux, it records games very well.
