- x264 open source encoder for H.264/AVC
- Google's VP8 open source VP8 encoder and decoder
- ZIP file includes encoder and decoder pre-built for windows
- Encoder is vpcenc.exe, type vpcenv -help for instructions
- Decoder is vpcdec.exe, type vpcdec -help for instructions

- Avisynth version 2.5
- General purpose scripting tool for reading and processing videos
- Allows filters to be bound in to compute distortion, add noise, watermarks, etc.
Useful avisynth filters:
* Compare - Compare two videos and Calculate Y-PNSR for each frame
- This is included as one of the core avisynth filters
Compare(clip_filtered, clip_original, "channels", "logfile")
* SSIM - Compare two videos Calculate Structure Similarity Metric for each frame
- http://avisynth.org/warpenterprises/
SSIM (clip1, clip2, "results.csv", "averageSSIM.txt", lumimask=true)
* RawSource - Read in Raw YUV video files
- http://avisynth.org/warpenterprises/files/rawsource_25_dll_20060728.zip
clip = RawSource("SourceFile", Height, Width, "Format")
- ffmpeg
- a complete, cross-platform solution to record, convert and stream audio and video
- includes libavcodec - the leading audio/video codec library
- contains instructions for getting source and windows executable
- YUVviewer
- Allows multiple YUV video files to be played side by side for comparison
- Vicos (Demo Version)
- Automated codec comparison tool
- Allows codecs to be bound in and preset parameters to be defined by the user
- Useful for a quick relative comparison of codecs and different preset parameters
- Generated files in vicos/perframe_data contains per-frame PNSR/SSIM raw data
- YUV Toolbox Matlab's toolbox for processing and comparing YUV video streams
- yuv_compare compares two YUV streams and produces PSNR values
- MSU's Codec Comparison Reports
- Contains short version of annual Codec Comparison Report
- Provides detailed comparison of the most popular H.264 decoders
- MSU's 2010 Codec Report - Appendix 8 compares VP8, x264, XViD performance and quality
