Olivier Langlois wrote into Phoronix this morning to talk about his new GLCS project. GLCS is based upon the GLC OpenGL game recorder, which is commonly used by Linux gamers for capturing their gaming experience for sharing. What differentiates GLCS is that it pipes directly into FFmpeg for a better user-experience with returning a much smaller output file straight away. Langlois cites about six minutes of 1080P footage being compressed to less than 200MB. With the smaller size, Langlois is also exploring live game-casting through RMTP for Linux.
The code for GLCS can be found via GitHub.
Those curious about the quality of the 1080P capture, Olivier has shared his initial capture below. However, the quality isn't in an ideal state: "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 shitty catalyst 14.2 release, it isn't possible for now.
