I'm using AVPlayer for play my video using slider and Some Buttons. Here is my methods for moving forward and backward using buttons.
-(IBAction)MoveForward
{
//int value = timeSlider.value*36000 + 10;
//CMTime newTime = CMTimeMakeWithSeconds(value, playspeed);
//CMTime newTime = CMTimeMake(value,(playspeed*timeSlider.maximumValue));
CMTime newTime = CMTimeMakeWithSeconds(timeSlider.value, playspeed);
newTime.value += 60;
[player seekToTime: newTime];
}
-(IBAction)MoveBackward
{
CMTime newTime = CMTimeMakeWithSeconds(timeSlider.value-1, playspeed);
[player seekToTime: newTime];
}
My Problem on this is the time to Seek is not working properly. That navigate to next frame based on seconds. I need to move next frame minutely. Help me...
I don't really understand your code, you don't really need separate methods to move forwards and backwards, you can use the same one for both. I've got a working AVPlayer Movie Player, I'll show you how I did the slider part.
-(IBAction)sliding:(id)sender {
CMTime newTime = CMTimeMakeWithSeconds(seeker.value, 1);
[self.player seekToTime:newTime];
}
-(void)setSlider {
sliderTimer = [[NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(updateSlider) userInfo:nil repeats:YES] retain];
self.seeker.maximumValue = [self durationInSeconds];
[seeker addTarget:self action:@selector(sliding:) forControlEvents:UIControlEventValueChanged];
seeker.minimumValue = 0.0;
seeker.continuous = YES;
}
- (void)updateSlider {
self.seeker.maximumValue = [self durationInSeconds];
self.seeker.value = [self currentTimeInSeconds];
}
- (Float64)durationInSeconds {
Float64 dur = CMTimeGetSeconds(duration);
return dur;
}
- (Float64)currentTimeInSeconds {
Float64 dur = CMTimeGetSeconds([self.player currentTime]);
return dur;
}
And that's it, there are two gotchas in this code, first, the duration property returns a CMTime variable, you have to convert it to a float, also, this returns the raw number of seconds, you have to convert it to h:mm:ss if you want to display time labels. Second, the updateSlider method is triggered by a timer every second. Good Luck.
