Function Documentation

probe_encoders()

int video::probe_encoders

(

)

Probe encoders and select the preferred encoder. This is called once at startup and each time a stream is launched to ensure the best encoder is selected. Encoder availability can change at runtime due to all sorts of things from driver updates to eGPUs.

Warning

This is only safe to call when there is no client actively streaming.
