steam video capturing and streaming under Linux

I have just released glcs.

I have released glcs, a spin of glc allowing to pipe its output directly
to ffmpeg generating much smaller output file. ie: My first 1080P
capture of 6 mins is smaller than 200 MB. This also open up a bunch of
new possibilities such as live gamecasting through RTMP.

If you are interested in trying it out, here is the official page:

My first 1080P capture is at:

video quality could have been better as I wanted to leverage my second
7970 card to use openCL during H.264 encoding but because of the bad
catalyst 14.2 release, it isn't possible for now:

It's very great, but ¿how to capture Steam games?
I can try with glc-capture --log=4 --log-file=glc.log --disable-audio --capture=back --draw-indicator -o BeatHazard.glc -s steam -console -dev -applaunch 49600 but don't record any video
Sorry for my english

Need to press Shift-F8 to start/stop capturing.
If you want to use ffmpeg to compress immediatly with H.264 or your prefered video codec, use switch See example.
I prefer using the defining all the env vars rather than use the glc-capture exec. It makes the cmdline shorter.

I have released v0.6.1 allowing to overlay a webcam video on top of the capture + mixing several audio streams to add audio commentary as I play. Quality picture has improved due to using better libx264 preset but audio is a bit out of sync and I believe that this is due to the usb nature of the v4l2 webcam video source as I explained in the video. Here is the youtube video of the demo.:

yeah! I have finally beaten the Iron cloud boss!
