Abstract
Systems and methods of transcoding video sequences for delivery in a mobile network. A source video sequence including source video frames is received and a source video frame type associated with each of the source video frames is determined based on a differential between a composition time stamp (CTS) and a decoding time stamp (DTS) associated with each of the source video frames. A frame type ratio value for the target frame-types is calculated based on a longest mini-GOP length. A target frame size of each target video frame is determined based on the frame type ratio value and a target transcoding rate, and each of the target video frames in a target video track is encoded to the target frame size to form a target video sequence.
