 |
|
| Righty... I have my lovely working webcam. And, of course, I can take snaps at regular intervals, upload those, etc, etc... just like a 'real' webcam. However, what I would like to do is really RECORD and AVI with that webcam, or MPG or whatever, but video format anyway, not snapshots. I can't seem to find a program for that, though....... anyone? |

I encode into a divx avi with mencoder (distributed with mplayer) using the following command:
| Code: | | mencoder -tv on:driver=v4l:adevice=/dev/dsp2:width=640:height=480 -o webcam.avi -ovc lavc -lavcopts vcodec=mpeg4 -oac mp3lame |

Okay, what I understand here is that I need to get the encoding type supported and that /dev/video0 is in use. But /dev/video0 isn't in use. When I start "camstream" it runs fine. I shut it down, try mencoder and I get this error. However, trying "camstream" again works without problems.
Sorry I'm so much trouble, I'm just pretty much a noob when it comes to video. I can setup my webcam to take the pictures with for example camstream and all, but that's about it.  |

ok, sorry adevice is the audio device (my webcam has a builtin micrphone) from the command you entered mencoder was probably trying to encode audio from your video input - not gonna happen! You probably don't need to specify a device, this should be detected, try something like:
| Code: | | mencoder -tv on:driver=v4l:width=640:height=480 -o webcam.avi -ovc lavc -lavcopts vcodec=mpeg4 -oac mp3lame |
hope that helps,
Herbie. |

Give | Code: | | v4lctl -c /dev/video setinput Composite1 |
You will probably have to replace /dev/video with the appropriate device.
Disclaimer: I haven't used this for a while. I _think_ this was the right command! |

| damn.....close but no cigar I guess. What is does is still try to record from the tv channel I think but it does seem to record. Audio is seemingly not there....I am using the linein on the sound card so should I specify another adevice option for that recording command? Im going to try to consult the mplayer page for more info since the man files for this stink. |
