Current version: 0.10.35
OS: Ubuntu 12.10

I used this commandline:

ffmpeg -f x11grab -s 1920x1080 -i :0.0 -r 30 -qscale 1 -vcodec mpeg4
/home/peter/test.mp4


Why I think it's a problem by gstreamer?

Long story ... true.

Half a year ago I also thought it's a problem/bug by ffmpeg but then i tried
other programms like Kazam, Eidete and XvidCap. But they produced so bad videos
(like recorded with 2fps). I searched long time but didn't find anything. Then
I started to ask in forums (www.ubuntuforums.org; www.ubuntu-forum.de → I'm
German; FFmpeg's forum). There I didn't get answer which could help me. Then I
found the programm recordmydesktop producing nice videos but I don't prefer
because it's no longer supported and it just need so much time for finishing
video after recording stopped (1 min for 10s recording). I also found another
programm but only able to record games, GLC. This one also gives me really good
results but only for games I don't need. Between all these "steps" i found
someone recording the game "Minecraft" using ffmpeg on Kubuntu.

→ It can work fine but not for me :(

Then I had the idea that it's maybe a bug of the graphiccard driver. So I
started asking the Nvidia Support. They also couldn't help me. We also started
testing with one of their machines. They also had such bad results. Then I
stopped the thing with the support, because I found this:

https://bugs.launchpad.net/kazam/+bug/910654

There someone has/had the same problem but with an ATI card not Nvidia like me.
So the thing with the driver wasn't anymore possible in my opinion.

Now I report a bug because in my way of understanding the bug report (link 5
lines above); I got the information that the recording most programms use
gstreamer to capture screen. And now I'm here ... That's why I think it could
be a gstreamer problem!


Here are my system specs.:

- AMD II X4 945 Processor x 4 → 4 x 3.0Ghz
  - had same results with 2 core-processor, 2.8Ghz

- Geforce GTX 550Ti by Club 3D → 3GB DDR3 Ram

- 8 GB Ram

- Ubuntu 12.04 / 12.10
