[BUG] Changing quality doesn't work on iOS 15.5, fine on Android

[daveshirman]

History check Yes - I've searched all the issues

Describe the bug If you change the quality whilst streaming on iOS, nothing happens, unless you manually seek to another point in the video. This works fine on Android.

To Reproduce Steps to reproduce the behavior:

1. Play a video
2. Invoke the Quality popup
3. Change to lower quality
4. Observe nothing changes
5. Manually seek using the slider bar - see the quality change

Expected behavior Quality should change after being selected (as it does on Android correctly)

Workarounds I've tried

• Listen to changedTrack event
• pause video, seekTo time + 1/-1, play
• doesn't work as per manual seeking.

@dcx15 @daveshirman have you guys managed to resolve an issue?

I've duplicated this issue into the more-less maintainable repository since the original author no longer supports this package.

I've not yet re-visited this one no. Any workaround your end that helps?

@daveshirman unfortunately not yet. I've been diving deep into the topic and seems like IOS AVPlayer doesn't allow to perform quality changes for HLS content. Due to Apple developer's threads, we need a server-based quality decision-maker for such purposes. Setting prefferedBitRate and prefferedResolution doesn't help.

I've referenced to it in he new issue - https://github.com/AnonymHK/betterplayer/issues/10
