[iOS]AVPlayerItemVideoOutput.hasNewPixelBufferForItemTime doesn't work correctly

Question

It\'s my first question here, so don\'t be severe.

I\'m playing video from the net using AVPlayer. I output the current frame using AVPlayerItemVideoOutput

Answer 1

Make sure that AVPlayerItem.status equals AVPlayerItemStatusReadyToPlay before calling - (void)addOutput:(AVPlayerItemOutput *)output method on AVPlayerItem

Reference：Renaud's reply on this page

I got the same problem with my implementation. After trying the solutions proposed here, I think I finally found the relable way to do things

The AVPlayerItemVideoOutput must be created AFTER the AVPlayerItem status is ready to play.

So

1. Create player & player item, dispatch queue and display link

2. Register observer for AVPlayerItem status key

3. On status AVPlayerStatusReadyToPlay, create AVPlayerItemVideoOutput and start display link

Thanks to all for the inspiration
