Hauppauge PVR-HD and IPTV plugin

Rob Davis <rob@xxxxxxxxxxxxxxxxx> · Mon, 08 Feb 2010 09:53:14 -0600

Hi, I have a Hauppauge PVR-HD which works but creating an h264 ts stream 
from a set HD component inputs and does quite a nice job of it.

The ts stream is available on /dev/video0 and a simple cat /dev/video0 
>file.ts will create a watchable high quality dump..

I have got this working with freevo (after a little hacking) but would 
prefer to get the input into vdr as I can then watch it around the house 
through streaming.

Using vdr-iptv I can get some of the way, but not all of it.. Playing 
around with different options I get either jerky video or ffmpeg just 
stops transcoding after a few seconds, and I'm not sure why...

I can put a 2 minute ts stream somewhere if it would help but I think it 
will decode a file before decoding from /dev/video0

Then it just freezes...

Any ideas?
