Actually, WMV appears not to be a container format - but a family of codecs. |

Apparently the .wmv files we see distributed on the net are most always WMV codec video contained in a ASF container. |

I don't believe I've ever encountered a .wmv file containing h264. One probably wouldn't actually notice, in normal use, if one did receive such a file, assuming it worked when one clicked on it. |

However I find it extremely unlikely to imagine anyone putting h264 in a .wmv file (or an ASF container). We all commonly put h264 in .mp4 or .mkv containers. |

I'm pretty sure we're able to play back WMV7, WMV9 / AC-1 videos without these binary decoders. It's probably not very useful to talk about codecs "nobody's seriously used since 1997." I *am* pretty sure that upstream mplayer *do* generally say "don't bother with the win32codecs". The goal here to to get Mark's video playing, and he's given no indication it's some old file he found on a 1998 system. |
