Find an Example of using Rate Control in OpenH264 Encoder #3226

Open jodyngo opened 4 years ago

jodyngo commented 4 years ago

I am studying about FFmpeg + OpenH264 for Android Application. I found that there is Rate-Control feature in Encoder part of OpenH264 ("Rate control with adaptive quantization, or constant quantization") so I would like to understand how to use it.

If anyone has experiments of using this function in Android application please give me an example code with many thanks.

Openh264 is mainly for real-time encoding, so for now there's only one way to set the RC method, i.e., by so-called rc_mode. The difference among these RC methods are quite minor. Adaptive quantization is another option. All of them can be controlled by passing the encoding parameter when doing Initialize() or SetOption().
