In this YouTube video, I go through how to screencast with FFmpeg. The configuration at first may look a little bit confusing but once you know what each parameter means, it becomes easy to apply any changes or improvements.
In case you don’t want to watch the video, I explain the parameters here briefly,
-f x11grab– records from screen-s 1920x1080– video size (here full HD)-r 30– frames per second-i :0+1366,0– record from display:0with starting X offset of1366and Y offset of0. If you have a single monitor no need to setXandYoffsets-f pulse– records voice from Pulse Audio-i default– uses default input device for recording Pulse Audio-c:v libx264– setting video codec-c:a flac– setting audio codec
There are also some other useful commands that I explain here as well.
To get display number run,
$ echo $DISPLAY #example output :0To get the display dimension,
$ xdpyinfo | grep 'dimensions:'|awk '{print $2}'That’s all for this video. If you are interested don’t forget to check out my YouTube channel or check the YouTube section of the site.
Happy weekend!
