Hi all

I want to record myself to see the expression on my face on average through the USB webcam .

I use mencoder for recording from USB webcam .

Code:

mencoder tv:// -tv driver=v4l2:width=640:height=480:device=/dev/video0:forceaudio:adevice=/dev/dsp -ovc lavc -oac mp3lame -lameopts cbr:br=64:mode=3 -fps 16.2 -o test16.2.avi

The problem is that the audio is not synchronized with the video.

what can i do ? help!

I had the same problem, and switched to ffmpeg:

Code:

/usr/bin/ffmpeg -f oss -i /dev/dsp -f video4linux2 -s 640x480 -i /dev/video0 \
                -threads 8 -target ntsc-dvd -aspect 4:3                      \
                -b 1500k -minrate 1500k -maxrate 1500k -bufsize 1835k        \
                -acodec libmp3lame -ab 128k                                  \
                webcam.mpg
