Dear video codec developers,
Moscow State University Graphics & Multimedia Laboratory
starts next seventh annual H.264 video codecs comparison.
New this year features:
- Videoconference Encoding Analysis
Due to the fact that videocoference encoding has some specific
that is quite different to transcoding tasks we plan to perform
special analysis for videoconference encoding.- New Metrics
We will use new objective quality metrics MS-SSIM and 3-SSIM
in addition to classical SSIM and PSNR.- GPU Analysis
This year we want to add GPU-encoders analysis to the comparison.
For this analysis we plan to use top GPU, e.g.
NVIDIA GeForce GTX 580.- HRD Compliance
We consider the possibility to perform HRD compliance test for
video codecs that support this feature.- Transcoding Analysis
Also we want to propose developers to take part in special
additional testing mode - transcoding analysis.
Developer sends us a pair (MPEG-2 decoder + H.264 encoder)
and we will test it for transcoding use-case we will take
MPEG-2 source video sequecnes to encode
them with H.264 encoder.
Important Dates
February, 1 - Deadline for receipt of a H.264 codec with presets
February, 14 - Deadline for settling technical problems with codec
March, 15 - Report's draft will be sent to all participants
