Does anyone of you know of good, preferably free, software that is able to record OpenGL applications and games?

....hmm.. you have to use software rendering if you want to capture 3D gfx... when the hardware does the rendering there is no software layer left where the capture-software could grab pictures... (AFAIK)

so... switch to software rendering and use what you like... or grab the TV-out of your gfx card with a TV-in card...

I will go to the shop tomorrow and buy one of them digiboxes you can save tv-programs and files to a harddrive and then burn a dvd directly if I understood it correctly, you think using tv-out to digibox in could actually work in recording OpenGL while running from the computer?

hmm... I posted a capture driver but not tried it. It was for Linux.

With that you could use vlc but I dont know if the unix version has a gui.. so might be a pain to mess around with.

VirtualDub is also a good program, I dont know if there's a Linux version.

I dont have a problem recording openGL on windows, but I usually turn on r_ignorehwgamma so what you record is what you see

On windows there is a great program called Fraps www.fraps.com/, it performs really well and you there is not much noticable performance when recording and playing at the same time. It runs in the background and as soon as you open an openGL program you hit F9 once to start and stop it recording. It has it's own Divx codec so doesnt use much space. So I'm sure if windows can do it, then Linux can too :)

But what Jack says makes sense, in some instances you would just see the desktop, but Im sure there are options to switch it.

I have a tuner card but not really had any use or problems with software drivers which are recognised as hardware. It might give you better performance and if you wanna watch tv it maybe worth the money :)

Is it necessary to record in openGL? I didnt think there was much difference when playing demo's so turn it off and i get much better performance.

I guess you never tried google. :)

glc is an ALSA & OpenGL capture tool for Linux. It consists of a wrapper library which captures stream and a tool for playing or processing captured streams. glc should be able to capture any application that uses ALSA for sound and OpenGL for drawing. It is still a relatively new project but already has a long list of features. Take a look at some example videos and find out how to install it!

glc is inspired by yukon (another, excellent real-time video capture tool for Linux) and Fraps (a popular Windows tool for the same purpose).

=======================================

graps is a tool for grabing frames from openGL application, without editing the application. graps can be used for making video from an opengl application. graps can also be useful for monitoring fps of opengl application.

graps is dirty fraps alternative for screen and realtime video capturing and fps monitoring ( hence benchmarking ).

You could use Fraps for it. But the demo Version is recording-time- and resolution- limited. So might just want to.. well.. buy.. the full version or something.
