full screen PAL video capture under linux....


Performed a search on the forums, nothing found.

Posted on videolan forum......does not help

...here you can read what I got...

The question is: I have tested both VideoLan Client and XawTV packages for analog video capture....and the results are excellent......up to 384x288

So I made a dive into videolan documentation and a quick reading of the man page of xawtv

It seems I cannot find my way into capturing to full screen 768x576 PAL resolution.....
BT848 drivers succesfully loaded into kernel 2.6.8-2-k7...everything running on an AverMedia TV Phone analog TV, composite and s-video capture card....

....are there any other tools out there, or am i missing something....???

Many thx in advance to you linux rulers out there....

I use mplayer/mencoder to do this. See the examples in the mplayer documentation.

Quick start guide for TV recording at 768x576 to MPEG4 video/MP3 audio:

mencoder -tv driver=v4l:width=768:height=576 \
-ovc lavc -lavcopts vcodec=mpeg4:vbitrate=900 \
-oac mp3lame -lameopts cbr:br=64 \
-vf pp=lb -o output.avi tv://

Nobber: as for the mplayer try......::

I want to record via the composite-video rca input; from an analog Video8 handycam...

I type

Code:
mencoder -tv driver=v4l2:width=768:height=576 -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=900 -oac mp3lame -lameopts cbr:br=64 -vf pp=lb -o capture.avi tv://
...but just a green screen outputs. Chances are that I did not tell mencoder to record from the analog 'composite' video input, instead of the tuner inputs, as I suppose it thinks by default.

How could I point mencoder to capture the signal incoming from the composite video input of the card??

Any clues....?

Yes, there are. Simply including -tv input=1 solved the whole stuff....

If you type
Quote:
mencoder -tv driver=vl4l2:width=768:height=576 -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=900 -oac mp3lame -lameopts cbr:br=64 -tv input=1 -vf pp=lb -o capture.avi tv://
...you get a full color 768x576 @25fps mpeg4 footage right into the file you specify right after the -o option....


As easy as abc.....once you get it, of course....

Greeetings...!!
