[FFmpeg-user] FFMPEG - area of desktop to record

eGreetings FFMPEG list,

I am trying to create a desktop recorder - so far have this cmd line:

ffmpeg -video_size 1024x768 -framerate 25 -f x11grab -i :0.0+100,200 -f 
alsa -ac 2 -i hw:0 output5.mkv

the recording of sound does not work - maybe someone can give me a 
pointer on this?

The main thing I'd let to know is - "is there a entry/ code that will 
make the area being recorded

be a specified area of the desktop?"

A big thanks for any help,
