MPMoviePlayerController: key frame issue

Question

I have a MPMoviePlayerController in my project. Documentation says that next call:

moviePlayer.initialPlaybackTime = time;

starts at the closest key frame prior to the provided time. Is it possible to start playing video from the specified time (not from the nearest key frame)?

Answer 1

No, it really isn't. Temporally compressed video streams can only generally start playback on a keyframe, as inter-frames depend on the keyframe for rendering. If seekability is important to you, consider making files with smaller keyframe intervals.
