Changing item the PCM buffer is not called anymore

[fabiosoft]

I can see the callback called goo on first item, when I change the item with method: replaceCurrentItemWithPlayerItem

    AVPlayerItem *item = [self audioItem];
    [self.player replaceCurrentItemWithPlayerItem:item];

the callback audioPCMBufferFetchedWithCallbackBlock is not called anymore.

I've also tried:

    [self.player play];
    [self.player setMeteringEnabled:YES];

    [self.player audioPCMBufferFetchedWithCallbackBlock:^(AVAudioPCMBuffer *audioPCMBuffer, BOOL iSuccess) {
        
    }];

forcing metering enabled to YES again...but nothing changes.

Are there come known issues with audio/video items?
How can I fix?

Apologies for the delay in replying. This should work again if you set metering enabled to YES again. I am not sure why it was happening since I was not able to reproduce this when I set it to YES again. If you found any solution, please submit a PR.

Hey,
From the way the codebase is set up, to fix this issue do something like this to fix this issue:

[self.player setMeteringEnabled:NO];
[self.player replaceCurrentItemWithPlayerItem:item];
[self.player setMeteringEnabled:YES];

I.E make sure to turn metering off before changing the player item and then turn back on after replacement.

This behavior happens because of the -(void)setMeteringEnabled:(BOOL)iMeterinngEnabled method in ACBAudioProcessHelper.m file.

- (void)setMeteringEnabled:(BOOL)iMeteringEnabled {
    
    if (!self.isMeteringEnabled && iMeteringEnabled) {
       c
    } else if (self.isMeteringEnabled && !iMeteringEnabled) {
        self.player.currentItem.audioMix = nil;
    }

    _meteringEnabled = iMeteringEnabled;
}

[self setupMetering] is never called for the new item unless you manually turn off metering and then turn it on again.

This should be fixed in v2.1. I have added a new replaceCurrentItemAndUpdateMeteringForPlayerItem which should do the above automatically. Please update here if it doesn't work for you.
