Huffyuv

Huffyuv (aka. Huffman YUV) is a very fast, lossless video encoder/decoder. VLC can play Huffyuv encoded videos. If you want VLC to output Huffyuv encoded video, then the right fourCC is HFYU.

For example encode MP4 file to AVI with Huffyuv video and MP3 audio:

vlc input.mp4 :sout=#transcode{vcodec=HFYU,scale=1,acodec=mp3,ab=128,channels=2,samplerate=44100}:file{dst=output.avi}

Because Huffyuv is lossless encoder, filesize is huge. e.g. two minutes of 640x360 resolution video will be near 700 megabytes.
