How do I start a GPU Encoding?
How GPU encoding from the Raspberry Pi in the datarhei Restreamer significantly reduces CPU load.
The graphics processor (GPU) takes over computationally intensive tasks and thus relieves the central processor (CPU). The function is directly controlled in the Restreamer with FFmpeg. The freed processor time can thus be used for other tasks.
