Hi all!
My OS - opensuse 11.3 with KDE 4 (FFmpeg version SVN-r25756)
I have a problem, connencted with ffmpeg(I have installed it from source). I try to grab video from my desktop, but when i run ffmpeg grabbing:

ffmpeg -t 120 -f x11grab -r 25 -s sxga -i :0.0 -f oss -i /dev/dsp -f avi /home/stalker_m6/Файлы/видео/desktop.avi

I get very bad quality, so i try to run grabbing with another codec - h264 :

ffmpeg -t 120 -f x11grab -r 25 -s sxga -i :0.0 -f oss -i /dev/dsp -vcodec libx264 -f avi /home/stalker_m6/Файлы/видео/desktop.avi

and get second problem:

x264 [info]: using cpu capabilities: MMX2 SSE2Fast SSSE3 Cache64 x264 [info]: profile High, level 1.0 error segmentation

So, i understand that my processor is not suitable with ffmpeg :’(

Who know how to solve this problem please reply me! Or say alternative of grabbing video from desktop.

I seem to have several such files loaded from Packman, they end with -72, -88, -98 and -107. You know I have a script file you can download to check your multimedia setup located here:

MMCHECK - Check Your Multimedia in 10 Steps - Script File, as proposed by RedDwarf

Message #40 has the most recent script you can download. Check it out.

Thank You,

I get very bad quality

Use the -b option to set a decent bitrate. The built in default is much too low.
