[FFmpeg-devel] Green artifacts in the beginning of the file, up to first inter-frame

Hi.

Some further updates on this issue - apparently it happens only on Windows
media player 11, on older versions it works fine.

Also, as another hint, the files are served by Apache 2 server, and may be
served before they were completely written. So this in effect a HTTP
streaming.

Perhaps some else have encountered something similar?

Thanks,
Stas.
