yes and no

sense as well. Of course only if the demuxer can handle an incomplete index.

Yes, .mov/.mp4 has a index which must contain all entries, they cannot
be continuously added during playback.

Many things microsoft did are stupid, but not doing something just because
microsoft did it is even more stupid. If everything ms did were stupid they
