I try to make screencast using avconv and I facing a problem. I finally succeed to record both pc output and microphone input , the problem is that they're not merged in the output file. (I saw they're an option filter_complex amix=inputs but its only in early release)

Is there any other way i can merge them (even if it's post production i don't care)

here the command line i use

avconv -f alsa -ac 2 -i pulse -f alsa -ac 2 -i hw:2,0 -filter_complex amix=inputs=2 -f x11grab -r 30 -s 1366x742 -i :0.0+1369,25 -map 0:0 -map 1:0 -map 2:0 -acodec flac -vcodec libx264 -preset:v superfast -crf 18 -threads 0 output.mkv
