xawtv seg fault

I am trying to get xawtv running on my machine. I had it working on my old machine, but it just wants to be stubborn now ...

I am using xawtv 3.85 on slackware 8.1 kernel 2.4.20. Has anyone else encountered this?

What output do you get when you load the bttv drivers for your card? Erm.. I guess you should also post info about which tv card you're using.

Sorry, it's a Hauppage WinTV card (the kind everyone has).

well there doesn't look like there's anything wrong there. xawtv 3.86 came out yesterday, try upgrading for the sake of it. segfaults are very rarely down to somethign like that, normally complaining about glibc upgrades or something.

mcleodnine · 03-19-2003, 06:18 PM

Is this a source build?

lackluster · 03-19-2003, 07:26 PM

This is xawtv-3.86, running on Linux/i686 (2.4.20)
Segmentation fault

ACK! Source build, yeah. Maybe it would help to compile with debugging?

nv? As in nvidia? Could it possibly be my nvidia driver? I didn't have this video card in the last computer.

acid_kewpie · 03-23-2003, 05:02 AM

what was that..? you're double posting..? tsk...

does appear to be nvidia though. i'd assume that that means you have installed an RPM rather than compiling the driver by source. i can't imagine that somethign like that would happen if the nv driver was compiled natively. personally i never had any trouble with xawtv / nvidia, but seeing as i'm boring i stopped using the nvidia drivers a while back and don't mess with opengl games now.

thelizman · 08-18-2003, 12:12 AM

Nvidia doesn't provide the source for their driver, and the nv driver that comes with many distributions is inherently flawed. While it's flawed in favor of XawTV, if you upgrade to the improved Nvidia driver (which delivers better opengl performance for gaming and video), then I suggest you dump XawTV. It doesn't seem to me that it's being supported very well anymore,w hich is the risk you take with open source. I switched to TVTime http://tvtime.sourceforge.net/, which is beautiful. It has a sleek OSD, but it is lacking in GUI interfaces. You have to remember keybindings. At the very least, you can just use the keypad to enter in the channels, and yes it does have LIRC support. It also solved the fulscreen issue, where I couldn't get a true fullscreen out of XawTV.
