Subject: [gentoo-user] Questions about recording webcam+mic on netbook
Date: Fri, 5 Oct 2012 03:19:46 -0400 [thread overview]
Message-ID: <20121005071946.GA1248@waltdnes.org> (raw)
I'm getting really ambitious with my 3-year-old Acer netbook, now that
open source Poulsbo video support exists. After tweaking the kernel,
I've got the webcam+mic recording with the command...
ffmpeg -y -f alsa -i plughw:0,0 -f video4linux2 -i /dev/video0 -f avi -vcodec mpeg4 output.avi
mplayer plays the output file fine with the command...
mplayer -vo x11 output.avi
Any suggestions for better options? Would x264 be an improvement? Is
there a way for the video to be displayed on the screen as it's being
recorded? Should I be looking at a program other than ffmpeg? BTW,
here is output from "emerge -pv ffmpeg mplayer" in case anybody has
ideas for improvements in my USE flags...
