We have built a real-time stream distribution program. When there is no receiver connection, we choose to pause sending the image to the encoder to save power, wait for a new receiver to connected, and then send the image to the encoder and restore real-time stream.
But every time the video frame is paused for a period of time (about a few seconds), the encoding becomes very slow when it is sent again. I noticed through GPU-Z that the clock frequency of the GPU and memory cannot be increased.
I think the graphics card may have entered energy-saving mode and cannot be changed out. Is there any way to put the graphics card into performance mode?
Normal:
Pause and Restore:
Restarting the encoder should be feasible, but the startup process of the encoder takes a long time (about 200 milliseconds), which makes the delay wave dynamic for our program too large.
