  • Trouble with the ffmpeg -ss flag when capturing one frame from a Macbook iSight webcam

    31 août 2011, par Andy

    For about five years I've used ffmpeg in a shell script to grab one frame from my linux'd-up Macbook's iSight :

    ffmpeg -f video4linux2 -s 640x480 -r 15 -i /dev/video0 -an -vframes 1 -vcodec mjpeg -y -sameq -ss 1.5 snapshot.jpg

    I just upgraded my Ubuntu distro from Lucid to Natty (ffmpeg ver. 0.6.2-4:0.6.2-1ubuntu1).
    Now that syntax turns the iSight on but hangs indefinitely.

    [output snipped, ending with:]
    
frame=    0 fps=  0 q=0.0 Lsize=      -0kB time=10000000000.00 bitrate=  -0.0kbits/s    
    
video:0kB audio:0kB global headers:0kB muxing overhead -inf%

    Without the '-ss' flag it seems to successfully grab the first frame and exit immediately - the only difference in output being :

    frame=    1 fps=  0 q=0.0 Lsize=      -0kB time=0.07 bitrate=  -2.6kbits/s    
    
video:16kB audio:0kB global headers:0kB muxing overhead -100.132730%

    However, the '-ss 1.5' was necessary to delay the frame capture by 1.5 seconds to allow the cam sufficient time to adjust the exposure.

    The -itsoffset flag seemed promising, but doesn't seem to change ffmpeg's behavior (ie doesn't hang, but no delay).

    Any ideas ?
