Near Optimal Per-Clip Lagrangian Multiplier Prediction in HEVC
Daniel J Ringis, François Pitié, Anil Kokaram
The majority of internet traffic is video content. This drives the demand for video compression to deliver high quality video at low target bitrates. Optimising the parameters of a…
Per-clip and per-bitrate adaptation of the Lagrangian multiplier in video coding
Daniel J. Ringis, François Pitié, Anil Kokaram
In the past ten years there have been significant developments in optimization of transcoding parameters on a per-clip rather than per-genre basis. In our recent work we have prese…
Per-clip adaptive Lagrangian multiplier optimisation with low-resolution proxies
Daniel J. Ringis, François Pitié, Anil Kokaram
This work focuses on reducing the computational cost of repeated video encodes by using a lower resolution clip as a proxy. Features extracted from the low resolution clip are used…
Per Clip Lagrangian Multiplier Optimisation for HEVC
Daniel J Ringis, François Pitié, Anil Kokaram
The majority of internet traffic is video content. This drives the demand for video compression in order to deliver high quality video at low target bitrates. This paper investigat…
Using modern motion estimation algorithms in existing video codecs
Daniel J. Ringis, Davinder Singh, Francois Pitie +1
Motion estimation is a key component of any modern video codec. Our understanding of motion and the estimation of motion from video has come a very long way since 2000. More than 1…
Encoding Bitrate Optimization Using Playback Statistics for HTTP-based Adaptive Video Streaming
Chao Chen, Yao-Chung Lin, Anil Kokaram +1
HTTP video streaming is in wide use to deliver video over the Internet. With HTTP adaptive steaming, a video playback dynamically selects a video stream from a pre-encoded represen…
