Hello,

I was using 4.0.0a1, and then I have updated sdk to 4.0.0a5.
Do I need to do any code changes with migration to 4.0.0a5
App crashed after a second after this code:

Code: Select all

 
             let media = VLCMedia(url: fileURL)
            self?.mediaPlayer.media = media
            self?.mediaPlayer.minimalTimePeriod = 1000
            self?.mediaPlayer.timeChangeUpdateInterval = 0.1
            self?.mediaPlayer.play()

This is what I see in console after the crash:

You should do a breakpoint on objc exceptions to see where the problem is.

I tried this, but it doesn't point me on exact line.
It just shows Thread 26: "-[VLCMediaPlayer handleEvent:]: unrecognized selector sent to instance 0x600003d05ef0"

Maybe an issue with handleEvent func? Can you try on your side?

Any updates?

Posted: **28 Sep 2024 18:39**

We are currently completely reworking the event management in VLCKit v4, so the best is too wait until this is done and the next alpha appears.

Posted: **30 Sep 2024 22:52**

Can you please notify me and let me know the version once you will release new alpha, so I can update and test?

Thank you,
Best regards,
