As far as I remember, the first frame the sequence header data applies to is the one with sequence number 0 (zero). This is always either an I or B frame, due to MPEG's frame ordering rules. But I often noticed that the switch occurred at the last P frame of the previous GOP instead - which is one frame too early. The bookmarks are set correctly, however, so I guess there's an off-by-one bug somewhere in the image processing chain. [...] >>The encoding of the images is the same anyway.

The letterbox bars either aren't transmitted at all, or they're part of the frame (and encoded in the same way). -- Michael "Tired" Riepe <[EMAIL PROTECTED]> X-Tired: Each morning I get up I die a little ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
