The Microsoft MPEG-4 codecs are similar to the ISO MPEG-4 coding standard but with various modifications to specifics such as Huffman tables and prediction methods. These are the different codecs covered under the umbrella of Microsoft's version of MPEG-4:
- Microsoft MPEG-4 version 1
- Microsoft MPEG-4 version 2
- Microsoft MPEG-4 version 3
- Microsoft Windows Media Video v1/v7 (WMV7)
- Microsoft Windows Media Video v2/v8 (WMV2/WMV8)
The full line of Microsoft MPEG-4 codecs is supported by FFmpeg, including XINTRA8 frames.
