I want to create some screencast, I am using avconv (recent ffmpeg counterpart) for doing so.
This is the reference for command I used. I also referred the avconv manual pages. Due to some reason I am unable to record audio from microphone into the screencast.
What is the
-f switch for audio from microphone? I tried
-f jack but it gives an error message.
I am not sure whether the microphone audio drivers are installed on my PC. Command I used is as follows:
avconv -f x11grab -f jack -s hd1080 -r 30 -i 0:0 screencast.mov
Error message I get is:
Cannot connect to server socket err = No such file or directory Cannot connect to server socket exec of JACK server (command = "/usr/bin/jackd") failed: No such file or directory jack server is not running or cannot be started [jack @ 0x9b6dc80] Unable to register as a JACK client 0:0: Input/output error
