Chris,
I looped the output of the 350 into the input of the 350 and it worked
without any problems. Picture quality is ok but as far as I can see I
miss the last GOP of my input file. When I tried to use the 150 S-Video
it only gave black and white pictures as reported earlier on the list.
This is much faster than using software transcoding and it does not use
any CPU time.
Thanks for the good working drivers.
Regards,
Michel Verbraak

You can loop the output to the input, of either the 350 into itself or to
the pvr150, it should degrade a little as expected with any transcoding,
but it is the best you can do at the moment since we don't know how to
use the hardware (or if possible) to transcode.
Thanks,
Chris

I have the following question:
Is is possible to change the bitrate of a recorded mpegstream by using
the hardware on a PVR-350 and or in combination with a PVR-150?
Explanation:
I have recorded a movie with my PVR-350 with a bitrate of 8000000 and a
bitrate_peak of 8500000. This movie is just a bit more than 2 hours long
and 4.6GB large. It will not fit on one DVD.
I can use avidemux2 to make a new mpeg stream with a lower bitrate but
on my machine it takes about 8 hours to do so.
Now I thought to use my hardware, I have a PVR-350 and a PVR-150. This
should only take me the 2 hours of the movie.
1st question:
Can I use only the PVR-350 to do the above? Something like "cat file.mpg
/dev/video16" and in another proces "cat /dev/video0 > newfile.mpg".
How do I have to setup the card to enable this? Currently I cannot find
any control options to set de decoder to output to the encoder. Or am I
missing something?
2nd question:
Do I need to hook the PVR-350 output up to the PVR-150 input for video
and audio? I have not yet tried this option because I do not have the
right cabeling at home right now.
Using: kernel 2.6.10 and ivtv-0.3.2p

Michel
