Call for MPEG4-AVC/H.264 codecs

Third Annual H.264 video codec comparison
For people, who make real research in field of high-end video compression

MSU Graphics & Media Lab (Video Group)

See CALL FOR CODECS of Fourth Annual MPEG-4 AVC/H.264 comparison!

Important Dates

  • August, 1 – deadline for receipt of a H.264 codec with required presets
  • August, 15 – deadline for settling technical problems with codec’s functioning

    • Task of the Comparison

    To perform comparative unbiased analysis of the current software implementations of H.264/MPEG-4 AVC video coding standard using objective metrics

    Scope of test

    Summary report topics:
  • Encoding and decoding time
  • Objective measurements (PSNR, SSIM, VQM, Average Advantage and etc)
  • Analysis of averaged objective results
  • Leaders in different areas
  • Cross-compatibility test
    • See previous comparison for details.

    Comparison Rules

  • There will be three types of testing sequences and for every type there will be specific set of presets, bitrates, and profiles:
  • HDTV streams
  • resolutions: 1920x1080, 1280x720
  • bitrates 1-10 Mbps
  • 2-pass encoding (1-pass is possible if 2-pass mode doesn't implemented)
  • speed requirements (at 3 Mbps, 1920x1080 sequences): minimum 0.4 fps.
  • Movie streams
  • different types of content (movie, animation)
  • resolutions: PAL, NTSC, 4CIF
  • bitrates 500-2000 Kbps
  • 3 presets: "1-pass High Speed", "1-pass High Quality" and "2-pass High Quality"
  • speed requirements (at 750 Kbps, 4CIF sequence):
  • Minimum 10 fps for "1-pass High Speed" preset
  • Minimum 4 fps for "1-pass High Quality" prest
  • Minimum 1 fps for "2-pass High Quality" preset
  • Videoconference streams
  • birates 30-300 Kbps
  • resolutions: QCIF, CIF, 4CIF
  • "High Speed" and "High Quality" presets
  • speed requirements (at 200 Kbps, CIF sequences):
  • Minimum 70 fps for "fast" preset
  • Minimum 30 fps for "best" preset
  • All codec’s options and presets should be provided by codec’s authors
  • An important restriction on a preset is encoding time for it. A few iterations of compliance testing and preset optimization are possible to meet the requirements set above
  • All speed measurements will be performed using our testing hardware (detailed description see below).
  • There will be two types of decoding:
  • All encoded sequences are decoding with reference JM decoder (for encoders testing)
  • All encoded sequences are decoding with its own decoder (for decoders testing, for example, decoders’ post-processing). The results of this type of decoding will be in comparison's appendix.
  • There will be cross-compatibility test (all possible encoder-decoder pairs)
  • All measurements will be performed using MSU Video Quality Measurement Tool (Pro Version)
  • Before results' publishing each developer will receive the results of its codec and competitive free codecs. Authors of each codec can write a comment (one paragraph) about the comparison results. That comment will be included in the report.
  • We are willing to completely or partially delete information about some codec in the public version of comparison report due to codec's developers request only in exceptional cases (e.g. critical errors in a codec).
  • If your company want to receive results of your codec testing without publication and information disclosure, you should pay for measurements and report preparing before comparison's beginning. You can join to comparison for free if you agree that your codec's results will be published.

    • Testing Hardware Characteristics

  • Processor: AMD64 3000+
  • OS Name: Microsoft Windows XP Professional
  • System Manufacturer: NVIDIA
  • System Type: X86-based PC
  • Total Physical Memory: 1 024.00 MB
  • Total Virtual Memory: 2.00 GB

    • Codec Requirements

  • You should point implemented H.264/AVC profile for each preset
  • Presets for different types of video sequences should be provided by the developers
  • Codec should allow to set arbitrary bitrate of resulting stream
  • 3 variants of codec interface are possible:
  • Console codec version (with batch processing support — bitrate and file names must be possible to assign from the command line). This variant is most preferable.
  • Video for Windows Codec with correct state saving (batch processing support)
  • Direct Show filter. In this case software for batch processing should be provided by the developers.
  • Codec should open and save *.yuv or *.avi (YV12 colorspace) files
  • Encoder should be compatible with JM 9.8 reference decoder

    • Developers Deliverables

    Following deliverables should be provided by each developer:
  • Codec files (CLI executable file is preferable)
  • Short description of codec parameters
  • Codec's presets with pointing of used H.264/AVC profile.

    • The Facts about the Previous H.264 Video Codecs Comparison

  • There were more than 50.000 downloads of previous H.264 video codec comparison results
  • Many codec's bugs were found and reported to developers
  • Here you can see Selected comments for MPEG-4 AVC/H.264 video codecs comparison

    • Sequences

    HDTV sequences:
  • Concert
    • Movie sequences
  • Battle
  • rancho
  • Matrix
  • Futurama
    • Videoconference sequences:
  • Foreman
  • Akiyo
  • Carphone

    Public MSU video filters
    Here are available VirtualDub and AviSynth filters. For a given type of digital video filtration we typically develop a family of different algorithms and implementations. Generally there are also versions optimized for PC and hardware implementations (ASIC/FPGA/DSP). These optimized versions can be licensed to companies. Please contact us for details via video(at)graphics.cs.msu_ru.     		MSU/YUVsoft filters for companies
    We are working with Intel, Samsung, RealNetworks and other companies on adapting our filters other video processing algorithms for specific video streams, applications and hardware like TV-sets, graphics cards, etc. Some of such projects are non-exclusive. Also we have internal researches. Please let us know via video(at)graphics.cs.msu_ru if you are interested in acquiring a license for such filters or making a custom R&D project on video processing, compression, computer vision.
