Does AVPlayer support closed captions delivered in a separate text file?

问题 My team produces iOS apps that play video using AVPlayer. We've recently been told that we MUST allow display of closed captions for all videos... but that the closed captions would not be coming as a track within the video files (we already support closed captions that come in this way). Instead, we'll be getting them as a separate text file. I've seen a couple references to including the caption text file in the SMIL, but I've found nothing about how to incorporate this text file into the

Firing events at specific times into a video played by MPMoviePlayerController (for Custom Captions on Movie)

由 冷暖自知 提交于 2019-12-11 09:14:43
问题 I'm considering implementing an SRT File parser for overlaying videos over an MPMoviePlayerController class. Can anyone think of a reliable way to fire off events at very specific times while a movie's playing? 回答1: Hmm, not as familiar with iOS as I am with AppKit, but doesn't look like there's a direct equivalent of AppKit's NSTimer class. I suppose you could always use CoreFoundation's CFTimer (found in CFRunLoop.h), or NSObject's: - (void)performSelector:(SEL)aSelector withObject:(id
