Adaptively encoding video frames using content and network analysis

A method for adaptively encoding video frames, the method comprising:

• predicting, via a processor, an instant bitrate based on channel throughput feedback received from a network;
• generating, via the processor, ladder info based on a received frame;
• determining, after a determination that the ladder info is not empty and via the processor, a frame rate, a video resolution, and a target frame size based on the predicted instant bitrate and the ladder outputs;
• determining, after a determination that the ladder info is empty and via the processor, the frame rate, the video resolution, and the target frame size based on a quantization parameter of a previously encoded frame and generated bits of the previously encoded frame;
• and
• encoding, via the processor, the frame based on the frame rate, the video resolution, and the target frame size.
