DVD playing stability.

[evulish]

I didn't really know what to call this post put good enough...

Ok, I was kinda nudged into playing DVD's in linux (since this is one of the few peices of hardware i have that works in linux and not in windows :)). I replaced my cd-rw with this 3 year old toshiba dvd-r drive. Nice DVD player.

I installed LiViD and libcss and all that other junk neccisary to play dvd's. I got it so it plays fine without audio but it's kinda jerky with audio enabled. My computer is fast enough, p3 1ghz 128mbram 32mb geforce2 mx (except the gfx card is using the wrong drivers since I can't get the nvidia ones to compile). Any idea if this would be a hardware or software error? And is there a way to fix this?

My semi-educated guess is the software puts too much of a load on the CPU but that doesn't seem quite logical with 1ghz. My other guess is my DVD-R is slow but I can't imagine that a hardware company would release something that isn't capable of doing what it was meant to do at it's best.

*shrug*

Any theories, suggestions, fixes would be appreciated.

It's from the video drivers, you'll need to get the nvidia ones working.

Ok, then my compiling problem is with NVIDIA_kernel 1.0-1251...

error states:
In file included from os-registry.c:67:
/usr/include/linux/module.h:21: linux/modversions.h: No such file or directory
make: *** [os-registry.o] Error 1


I haven't a clue on how to fix that.

Looks like you either
A) don't have the source for your kernel or
B) This install doesn't like the source you have. two solutions

A) Get the rpm's. Before install the GLX you need to remove a few files. You should be able to find these around but if you can't, just run these.

rm /usr/lib/libGL*
rm /usr/X11R6/lib/libGL.so*
rm /usr/X11R6/lib/libGL*.a
rm /usr/X11R6/lib/modules/extensions/libglx.a
rm /usr/X11R6/lib/modules/extensions/libGLcore.a

B) The other solution, probably preferable, is to find the source(or recompile your kernel so you have the source.)

If you do this, you'll need to tell the install script where the kernel is. Example, if you kernel is in /usr/src/mysource you'll run

make SYSINCLUDE=/usr/src/mysource/include

Hope this helps, if you have any problems please post them. And DVD's run 100% on my system with VideoLAN :)

What distro are you using? is it the default kernel?

The glx stuff *only* concerns opengl support and has nothing to do with X working or it playing DVD's so don't worry about that at first.

[evulish]

I'm using Debian woody running kernel 2.2.19pre17. I've compiled other stuff before and it didn't give me any problems.

[word]

Debian does not link /usr/include to /usr/src/linux/include.

You'll have to do what ethereal said:

make SYSINCLUDE=/usr/src/linux/include

[evulish]

Hmm, ok, this make SYSINCLUDE thing is a bit more than I had expected. I hope I can't **** (pardon) up my system too bad.

[evulish]

What do I do after make dep?

[evulish]

OK, never mind those 2 posts. All I had to do was install kernel-headers and now it works.

It didn't do anything for my dvd performance though.

[Malakin]

Can you drag the video window so it's covering at least 800x600 but not running full screen without a massive performance loss? If not then the video acceleration is probably not working. If you're sure the nvidia drivers are installed and working then I'd try a different dvd player or play with the config on the current one.

When I went from nv to nvidia the difference was massive, went from super choppy video that kept stopping to super smooth and I could drag the video window so it covered my entire screen at 1152x864 without any slowdown. This is with a GF DDR and a p3 800.

I have problems with the nvidia drivers as well . Well , not really problems - coz i could install them without any problems - but watching DivX videos is stil not smooth . I have a geforce2 MX and an athlon 1333 MHZ processor- so there shouldnt be any problems from there . Stil video is not really smooth . :(
