Screencasting with FFMPEG in Arch Linux

After toiling around the Internet I have found a solution to my problem with screencasting. This line of code gives my perfect synchronization with audio and video every time! Make sure you read the ArchWIKI covering codecs and the installation thereof otherwise this command string may not work!

ffmpeg -f alsa -ac 2 -i plughw:1,0 -f x11grab -r 15 -s 1360x768 -i :0.0 -acodec pcm_s16le -vcodec libx264 -preset ultrafast -threads 0 output.mkv

Does it work in ubuntu?

[LinuxSpatry]

@Armydude771 it should but you may have to alter the command to fit your needs... This is covered in detail on Ubuntu forums. The latest kazam has just been released and that may be a better option.

actually you use as much threads as possible, not 0. The second thing, regardless how complex does it look (or is) its not a code, just a command call with a lot of arguments.

@ClansmanAliasTool I stand corrected... thanks!
