Sundtek MediaTV Pro (Europe) / Capturing with mencoder
« am: Mai 05, 2011, 01:42:40 Vormittag »
I'm trying to capture from composite with mencoder.

This is the command I'm using

mencoder -tv driver=v4l2:input=1:width=720:height=576:device=/dev/video1:fps=25:amode=2:norm=PAL-BG tv:// -oac lavc -ovc lavc acodec=ac3:vcodec=mpeg4 -o test.avi
Then what happens is that I can hear the audio from the source and receive some errors aswell. Mencoder also just outputs a 0byte file.

What am I doing wrong?

Sundtek MediaTV Pro (Europe) / few questions
« am: August 16, 2009, 03:24:38 Vormittag »

My understanding is that the MediaTV PRO is fully supported by linux, does that just mean plug and play on a 2.6.28-14 kernel or do I need to install some driver?
Have you had any reports of linux users not being able to get your cards working?

Could you ship to iceland?
