So run: rmmod ivtv
and then: modprobe ivtv

Also, it seems that the case where mplayer would stop playing from /dev/video0 was when I attempted to execute: mplayer pvr://

And as you’d expect, upon reloading ivtv - the input settings are reset to defaults.

I used v4l2-ctl, it’s actually pretty easy. I wanted the Composite 1 input selected, so for me, I just ran:

v4l2-ctl -i 2

Just run the v4l2-ctl –help command and you’ll see your options. The highlights to me are:

-n -> Displays video input sources
-i -> sets video input source
-I -> shows current video input source
–get-audio-input
–set-audio-input

So now when I run mplayer pvr:// I get:

Playing pvr://.

Still have that failure, but at least it’s using the sources I wanted.

I also would really like to know how to change the video input sources. Seems this is something that should be do-able from mplayer, however perhaps I have to use some other control for v4l2 or ivtv to make that change?

Also, when I first boot my machine and run mplayer /dev/video0 - get a window of static.. After awhile (not sure what triggers it) that ceases to work. All I get is mplayer seemingly hanging with the message “Playing /dev/video0.”

help would be deeply appreciated.

Thanks

It shouldn’t be too hard to make a patch to fix this?

I think it is an ivtv 0.9.1 / svn problem?

I bought my PVR when I was in Korea and live in a PAL country so it will be fun to get an IR blaster to control my DVD player to use as an external tuner.

I’m also running ivtv-svn .. I’ll post my success / failure shortly!

Hans Verkuil can be thanked for this as he designed the api and afaik coded the whole thing.
