Hi,

I'm getting issues with OpenGL with VLC.
I thought it was an OpenGL issue, but mplayer can stream fine with it, and glxgears is working fine.

I'm using 0.8.6i, but tried with 0.9.1 which gives similar results.
I'm using Gentoo, with everything up to date and seemingly in order.

It used to work fine with a NVidia card, then I changed to an ATI which I never really got working with any acceleration, then installed a new NVidia (GeForce FX 5500) and did a major software upgrade (about a years updates on a Gentoo system).

Audio works fine, but when it tries video, it dies with the following message:
[00000286] main private debug: looking for opengl provider module: 1 candidate

Below is the full output. If anything else would be useful, then I can provide. I'm savvy with Linux, but not above the occasional silly mistake
If it's any help, here's the output when I tried it quickly with 0.9.1. I've tried it with different videos, and another user.

Any help would be greatly appreciated.

Thanks

Our video output module need some love ... nobody's been coding on them for a few years now

Doesn't the xvideo module work?

Yeah, it works, but with blue lines on the top and left.

Is there a magic way to get rid of these instead? They get REALLY annoying when watching a movie. So I've had to go over to mplayer, which has problems of its own

Blue lines on top and left sound weird indeed Maybe something to do with your xorg.conf ...

(Does the x11 video output also have those?)

Thanks for the replies.

I don't think it's an issue with the xorg.conf, I've tried various ones, and I don't have this problem with anything else. If there's anything specific I should be looking at, I can check.

OpenGl - Crashes
Xvideo - Blue lines
X11 - Slow, not great quality
Caca - Don't even go there.

x11 quality should be good in 0.9.x (but slow ...)
If you know anyone with good xvideo or/and opengl coding skills with a bit of time to spare, we'd gladly welcome him/her in the team

I didn't really test x11 in 0.9.1, was mainly trying to get OpenGl working when that was installed, but may try it.

Thanks for your help. It's a great piece of software that covers everything I need, it's just unfortunate that I've managed to break it

I'll be changing my graphics card on the off chance it's something silly with that, but think I'm at a dead end otherwise.

Thanks again.

Hope this isn't resurrecting an old thread, but with any of 3 different NVidia cards, I kept getting the same OpenGL error.

However, only the GF FX5500 showed the blue lines using xv, the two other geforces worked fine with xv. So all is good and working, but still slightly confusing.

Cheers all
