ffmpeg -i video.mp4 -c:a copy -c:v ayuv output.avi should do the trick, where 'ayuv' is one of the possible codecs as example. Avi is a container of streams and thus does not know anything about 'converting'.
It is a huffyuv like codec except it is not backwards compatible with huffyuv. That is a codec that only contains I-Frames. The tool is command-line only, which means it doesnt have a graphical, clickable interface.
The paper linked above includes a lot more information, images, and links to further resources. FFmpeg is an open-source media tool you can use to convert any video format into the one you need. Source COMPARISON OF LOSSLESS VIDEO CODECS FOR CROWD-BASED QUALITY ASSESSMENT ON TABLETS (pdf) authored by Christian Keimel, Christopher Pangerl and Klaus Diepold. Also only a fixed table for the Huffmann code entropyįFvYUV is an extension of HuffYUV developed by the FFmpeg project to address some of HuffYUV’s short-comings: instead of a fixed Huffman table, context-adaptive Huffman tables are used for the entropy encoding. NVENC and NVDEC can be effectively used with FFmpeg to significantly speed up video decoding, encoding, and end-to-end transcoding. Is selected a-priori to the encoding and then used for the complete FFmpeg is the most popular multimedia transcoding software and is used extensively for video and audio transcoding. Note, that the model selection is not adaptive, but rather one model The median model selects the median value from the model left, the model gradient and from the pixel a above x The second model, gradient, predicts x as x = l + a -d and The first model, left, only uses the pixel l to predict the pixel x as x = l, Prediction selects between three different prediction models: left, It combines an intra-frame prediction withĪ consecutive Huffman entropy coding of the residuals. HuffYUV was proposed by Ben Rudiak-Gould as an alternative to What are the differences between the HuffYUV and ffvhuff codecs?
