Described herein are systems and methods for processing and transmitting data included in packets with jitter. The systems and methods combine a jitter buffer and a buffer scanned by a look ahead window as a combined buffer. The combined buffer varies look ahead window and performance of a process that uses the look ahead window based on the current jitter support in the buffer. More specifically, the flexible buffering techniques flexibly adapt the size of the look ahead window based on the amount of buffer space used for jitter support. When jitter support requirements are low, the size of the look ahead window is increased. When the look ahead window is implemented with a multiplexer, the multiplexer may benefit from a larger look ahead window and improve multiplexer performance. Improved multiplexer performance may lead to less or more intelligent re-encoding and bit rate reduction for video data transmission applications, leading to improved decoded output video quality.
