RE: [mythtv-users] PVR-350 TV Out

It is possibly the alpha setting. The x driver does not reset the alpha setting so if global alpha is 0 then you wont see anything but in that case you would normally see a black image so that probably isn’t very likely.

 

Does the image change when you start X.

 

You could also try running

 

ivtvfbctl /dev/fb0 –prepdma

 

This writes to the frame buffer an image that gradually  changes from black to white.

You should run that instead of X to see what happens.

 

If you don’t get anywhere you could enable more debugging

 

ivtvctl –D 0xBF

and then start X.

If you could then post your messages file including the sections about ivtv starting till it ends its initialization and then the section when X starts  I may be able to spot something. Since It may be large either post it on a web site or mail me directly if you like

 

Which version of ivtv are you using?

So I can pump video captures (mpg or live from /dev/video0) manually, dd,  out the TV Out.

 

I try to bring up X through the TV Out and no luck, I seem to get a bunch of lines and color. The image is fixed, no motion or changes.

 

I have tried many variations on the xorg.conf

 

Anybody have suggestions?
