Comment:
No, I had not completely understood the issue myself originally, sorry.
H.264 can be muxed in different ways. WMP supports H.264 in avi only with
fourcc H264 which indicates a H.264 elementary stream with startcodes
(while fourcc avc1 indicates a stream without startcodes). So only if you
choose fourcc H264 startcodes have to be present. This will be enforced in
a commit later today.
If you use another fourcc than H264 for H.264 video, WMP will not play the
resulting file. So far, we believe that other fourccs are also valid and
that there is nothing about this that can be fixed within FFmpeg.
