AVPlayer playback issues, pause and buffering
My application is playing streaming video, but when it is buffered the player goes into pause mode and I have to set it to play mode again manually, I have the following code in my AVPlayer class to handle this situation, but it doesn't work.
In the ViewDidLoad method
[playerItem addObserver:self forKeyPath:@"playbackBufferEmpty" options:NSKeyValueObservingOptionNew context:nil];
[playerItem addObserver:self forKeyPath:@"playbackLikelyToKeepUp" options:NSKeyValueObservingOptionNew context:nil];
and then referring to observers using the following methods
- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object
change:(NSDictionary *)change context:(void *)context {
if (!player)
{
return;
}
else if (object == playerItem && [keyPath isEqualToString:@"playbackBufferEmpty"])
{
if (playerItem.playbackBufferEmpty) {
//Your code here
}
}
else if (object == playerItem && [keyPath isEqualToString:@"playbackLikelyToKeepUp"])
{
if (playerItem.playbackLikelyToKeepUp)
{
//Your code here
}
}
}
is there any other solution to this problem to force the player to keep playing?

This can help,
suppose this is your AVPlayer object
player1 = [AVPlayer playerWithURL: streamURL];
When your video is buffered, you can pause it and when it will play again, for example: In the observer method
if ([object isKindOfClass:[AVPlayerItem class]])
{
AVPlayerItem *item = (AVPlayerItem *)object;
//playerItem status value changed?
if ([keyPath isEqualToString:@"status"])
{ //yes->check it...
NSLog(@"STATUS = %d",item.status);
switch(item.status)
{
case AVPlayerItemStatusFailed:
NSLog(@"player item status failed");
break;
case AVPlayerItemStatusReadyToPlay:
[playButton setTitle:@"Pause" forState:UIControlStateNormal];
[player1 play];
NSLog(@"player item status is ready to play");
break;
case AVPlayerItemStatusUnknown:
NSLog(@"player item status is unknown");
break;
}
}
else if ([keyPath isEqualToString:@"playbackBufferEmpty"])
{
if (item.playbackBufferEmpty)
{
[playButton setTitle:@"Play" forState:UIControlStateNormal];
[player1 pause];
NSLog(@"player item playback buffer is empty");
}
}
}
or you can save this event with a button click. Place one button on the screen to support play and pause and addTarget with OnClick event.
