Hi,
Is there a way to test the composite and SVideo inputs on the
PVR-150/250 family from the command line like we do when we capture
test video from the tuner?
Thanks,
Mark
I wrote a script...
It takes an argument which can be file to play or "composite" or
"svideo" or any tv station name which "tune" can tune to.
My tune script only translates sender names to IDs ptune.pl understands.
The script is killing a running mplayer instance. This was necessary at
the time when the driver was not as good as it is now. At that time
mplayer froze when the PVR150 was tuned to another channel.
I've wired my VCR to both s-video and composite inputs and I have not
made sure that the audio I select is definitely s-video or composite.
I could check by unplugging one or the other, but I didn't bother yet.
However, if you measuring the signal quality is what you want, this
obviously is not what you are looking for.
