In the included patch, open a video file with the read message. Once the file is read, its length is asked, and when the frame count is sent, then I want to jump at the end of the movie. But jit.movie doesn't output the expected seeknotify message. It will if the frame_true message is resent by hand, or if a rather long delay is inserted.

What am I doing wrong? Using a delay is something I prefer to avoid…
