KWinTV Rewrite Alpha 1

As scheduled, the KWinTV rewrite has left the vapourware stage with the first alpha now available. It looks great already, and should become a killer application for those of you owning a TV card. " This release is intended as a basic demonstration of the design of the application. It provides functionality in the form of support for Xv video streams, OSS mixer (/dev/video, mixer 0), and XML channel files. It most likely only works on Linux, and in fact may only work on ia32 hardware. Camera devices may or may not work." See the Alpha 1 announcement for full details on what is and what isn't working at this point.



Thanks to the kwinTV authors for giving me an alternative to that crappy xawtv!

I just compiled Alpha1 sucessfully. When it starts up, I have to select a video device and a video source. Both are drop-down-boxes. Problem is that I can't drop them down because they're empty. So, basically, I can't select a video device or source. It doesn't seem to accept cmd-line options either.

Is that a bug or did I miss something?

I think you didn´t miss anything. It´s a bug. I experienced the same problem. On the kwintv mailing list (look at www.kwintv.org), There is also a thread about it.

You probably forgot to add the v4l module to your XF86Config. If you don't do this
it won't work.


By Richard Moore at Mon, 2002/07/01 - 5:00am

Did you add the load "v4l" to your XF86Config? After that, the boxes are not empty.

my advice:

stick with the former kwintv. (see what they say at http://www.kwintv.org)

that rewrite is far from being usable.

former kwintv version that is in cvs works with KDE3, and has a bunch of all the features which are missing in that alpha 1 version.

pay attention that that CVS version is touchy to compile, and u'll have to modify by hand the Makefiles if u want things like fullscreen.

You might want to try zapping until the latest kwintv stabalizes.. zapping has support for XV video overlay and also has capture support.

When will our KDE be Video enabled? it is KDE 3.1 or later? BTW, Please suggest a best (not so costly) AGP card for KDE+Linux for better experience. Will Nvidia Geforce works great with detonator drivers? Since performance of DE is based on the speed of rendering by the display card.

By KDE User at Mon, 2002/07/01 - 5:00am

Don't expect proprietary drivers to work well with free software.

That's the biggest advice I could give you if you're shopping for a video card.

By Neil Stevens at Mon, 2002/07/01 - 5:00am

I have had good luck with the NVidia drivers. im running a geforce 256. I will not talk about proprietary software though. might start a flame war.

By Echo6 at Mon, 2002/07/01 - 5:00am

The kernel part of the driver is open. Nvidia's gl implemention is not.

By Bluewolf at Tue, 2002/07/02 - 5:00am

No it isn't, there's an open wrapper which links in a binary-only object file

While i would generally agree with you, i have to add that i have actually had much better experiences with nvidias closed source drivers than with matrox open source drivers. I had problems with crashes earlier, but in the last year or so i havent experienced a graphics lockup once.

But yes, i wish they would open their driver, but until they do i will have to do with the closed one if i want hardware 3d accel, which i do as the newly ported opengl screensavers look darn nice :)

By troels at Mon, 2002/07/01 - 5:00am

You can also use the latest Utah GLX to get hardware acceleration on nvidia cards. I have no idea if it's any faster or not, though.

By Carbon at Wed, 2002/07/03 - 5:00am

That isn't some type of warning about free software not working with cards that
have propietary drivers is it?

By Old Pink at Mon, 2002/07/01 - 5:00am

Everyone that i know who runs (i mean really runs) linux all have nVidia cards: TNT2 Ultra, GeForce 1, GeForce 3 Ti and a Geforce 4 Ti. We've had no problems running anything that we've thrown at it including quake3 and the like ... The performance is also right on par with windows (usually exact actually) with nVidia's drivers. I also do some graphics development with SDL and not a single glitch their either ...

Also dont forget all the nVidia driver specific stuff you can do with X like cursor shadows etc... (Appendix D) http://download.nvidia.com/XFree86_40/1.0-2960/README.txt

Downside... cannot use valgrind yet!! with qt and kde using the nVidia drivers

On the other hand if you want to go with another non-nVidia card expect lengthy delays between driver releases, no extra features, and slower performance than can be had on windows. That of course is all second hand knowledge gained mostly by laughing at some other 'friends' who try to get their cards to work But I will say that ATI support has improved but then again ...

By Jesse at Tue, 2002/07/02 - 5:00am

I would say that I *really* use Linux - I haven't used anything else for my desktop in a couple of years. Plus I have several friends that run Linux as their primary desktop. None of us have nVidia cards... but then, none of us play games other than a bit of solitaire.

I personally use Matrox and ATI cards - most of my systems have one or both of these. My current main system is a triple head system with a Matrox G400 and an ATI All-in-Wonder Pro. I have video in and, if I switch over a monitor, video out (if I were just running dual head, I could have video out all the time). I can easily play full screen video with no problem and watch TV in a window (well, I just moved, so I don't have TV in hooked up right now).

I've never played Quake3 - it's quite possible I've never even *seen* Quake3. My point is, you have to choose what you want to do with your system and pick a video card that matches your needs and your budget. To me, video is nice, but I don't even know if I'm running hardware accelerated 3d - it's not like it lets me ssh to my servers any faster. As long as I can watch a few DVDs and the occasional DivX of a Buffy episode, I'm totally satisfied.

Oh, and as long as I can get 1280x1024 on three monitors. Yes, I like my screen real estate.

First, please read the release notes in full. You must have the line:

Load "v4l"

in the modules section of your XF86Config. We don't support V4L directly yet, only Xv.

Next, restart your X server after adding that line, and make sure that your bttv or other kernel drivers are loaded before your X server starts.

If you still don't get any devices, then run "xvinfo". Try to decipher the output and see if it makes sense to you. If you don't see your tuner listed there, then that's why it's not working. If you do see it there, then please send the output to the mailing list including a description of your hardware, software, setup etc.

What is all this bloat for! I need to watch tv, not interface. XawTV does not give me all this crap and is very usable!

By Wouter de Vries at Wed, 2002/07/03 - 5:00am

If you switch the view mode to 'TV mode' you get a bare tv widget like xawtv.
Personally though I don't regard xawtv as particularly usable though (neither does its author which is why he's working on motv too).
