How to record video using on-the-fly encoding on graphics adapter?

Question

linux

I use SimpleScreenRecorder, Kazam, however, the processor is rather weak, and the extra load on the whole core is not always welcome, but the video card is constantly idle. Can I somehow record video using the power of the video card?
AMD Radeon 8650G graphics card that supports AMD APP.
Driver - xf86-video-ati.
I can roll a proprietary one, if it has such a feature ...

Answer 1

I'm not sure if the AMD APP can be used in any way in video stream compression. In general, video cards usually have hardware support for video decoders, not encoders.
