I’ve read some discussions about the asynchronous nature of avf backed jit.movie, but does it explain the fact that when I ask for a specific time (with time message), I get a different value from the dumpout outlet ? (Max 7.03 - Mavericks)

(see patch below)

jit-movie-avf-and-time-message

I think seeknotify message doesn't exist in QT world. But with qt engine, if you send a bang after a time request, it works properly.

Thank you for your reply.

it's simply due to time format conversion rounding.

is this causing a problem in patch logic?

Maybe it's not really a problem in patch logic (I don't know yet), but it's confusing ...

In fact, I'm working on a patch to play continuously a movie file with the ability to jump (as precisely as possible) sometimes to cue points in the movie file to be in sync with live music events.

Do you think it's possible with avf engine (qt playback engine is not fluent enough in my case) ?
