ffmpeg/libav works well for capturing input from webcams, at least if |
14 |
the driver uses the video4linux (v4l) framework (I haven't encountered |
15 |
any other kinds). For instance, to capture one frame and store it as a |
16 |
png image (using libav's avconv, ffmpeg would be similar), you can use |
17 |
avconv -f video4linux2 -i /dev/video0 testframe.png |
18 |
|
19 |
mplayer (and its descendants) also play well with v4l, to directly |
20 |
display the webcam's input you can use |
21 |
mplayer -tv driver=v4l2:device=/dev/video0 tv:// |
22 |
(The -tv switch and its argument are probably redundant as the default |
23 |
detection is very good.) |
