Code

ensure that avi files have a valid header as soon as possible.

Browse Source 
without this, the header says 0x0 video size, which works with mplayer
when the video size is stored in the codec data, but it does NOT work
with other players or with codecs that don't store size (e.g. snow).

actually i don't like having seeks in the muxer module, but i don't
know any other way to implement this fix without major changes to
mencoder. if you have a better fix, please reverse this and commit
yours.
