Abstract
A method for real-time video encoding includes buffering frames in an encoder input buffer, retrieving the frames from the encoder input buffer, encoding the retrieved frames into a bit stream, monitoring the encoder input buffer for buffer overflow, and, if the encoder input buffer is about to overflow, encoding one of the retrieved frames as a pseudo-frame that completely references one reference frame of the one retrieved frame. Encoding one of the retrieved frames as a pseudo-frame bypasses a majority of the encoding procedures to improve the overall encoding speed. The method further includes monitoring a hypothetical decoder input buffer that models an actual decoder input buffer in a video decoder, encoding one of the retrieved frames with a pseudo-frame if the hypothetical decoder input buffer is about to underflow, and adding stuffing bits to the bit stream if the hypothetical decoder input buffer is about to overflow.
