AVPlayer streaming progress

It should work well:

Objective-C:

- (CMTime)availableDuration
{
    NSValue *range = self.player.currentItem.loadedTimeRanges.firstObject;
    if (range != nil){
        return CMTimeRangeGetEnd(range.CMTimeRangeValue);
    }
    return kCMTimeZero;
}

Swift version:

func availableDuration() -> CMTime
{
    if let range = self.player?.currentItem?.loadedTimeRanges.first {
        return CMTimeRangeGetEnd(range.timeRangeValue)
    }
    return .zero
}

To watch current time value you can use: CMTimeShow([self availableDuration]); or CMTimeShow(availableDuration()) (for swift)

I am just working on this, and so far have the following:

- (NSTimeInterval) availableDuration;
{
  NSArray *loadedTimeRanges = [[self.player currentItem] loadedTimeRanges];
  CMTimeRange timeRange = [[loadedTimeRanges objectAtIndex:0] CMTimeRangeValue];
  Float64 startSeconds = CMTimeGetSeconds(timeRange.start);
  Float64 durationSeconds = CMTimeGetSeconds(timeRange.duration);
  NSTimeInterval result = startSeconds + durationSeconds;
  return result;
}
