Trouble with recording IP Camera.

djmentos · Feb 2, 2013

Hello!

I bought last time IP camera which transmit video using mjpeg codec. I'd like to record it using FreeBSD with multimedia/mencoder, and here is the problem.

Could you look for it?

Code:

root@siemens:/home/me/Wideo# /usr/bin/mencoder -prefer-ipv4 -fps 15 -demuxer lavf "http://192.168.1.131/videostream.cgi?user=admin&pwd=admin&resolution=32&rate=25" -nosound -oac mp3lame -ovc xvid -xvidencopts pass=1 -o /home/djmentos/Wideo/camera/test.avi

Why it's not recognize mjpeg?

I've had good results using multimedia/vlc for this purpose. cvlc will run without any X11-components if that's what you're after.

Tanks OH, multimedia/vlc works for me fine.

Do you know is there any way to include time caption on video while transcoding?

Usually this is a job for the camera.

I know, but my camera comes from China and was very cheap, it is not possible

I must do it using software.
