iOS app crashing while trying to cast m3u8 stream

[ururus]

Describe the bug
iOS app crashing while trying to cast m3u8 stream. I able to select and connect to chromecast device, but right after it connected it crashes. Same stream on the same screen with same parameters on android is working properly.

Code

registerGoogleCastListeners = (currentStreamUrl) => {
    const {isGoogleCastConnected} = this.state
    
    GoogleCastEvent.addListener(GoogleCast.SESSION_STARTED, () => {
      this.setState({isGoogleCastConnected: true})
      GoogleCast.castMedia({
        mediaUrl: currentStreamUrl,
      })
    })
    GoogleCastEvent.addListener(GoogleCast.SESSION_ENDED, () => {
      this.setState({isGoogleCastConnected: false})
    })
    if (!isGoogleCastConnected) {
      GoogleCastEvent.addListener(GoogleCast.MEDIA_STATUS_UPDATED, () => {
        this.setState({isGoogleCastConnected: true})
      })
    }
  }

also tried to add

contentType: 'application/vnd.apple.mpegurl',
isLive: true,

in different combinations, but still no results.

Versions:

• RNGC Library Version: 3.2.0
• iOS: 13.3, 14
• 'google-cast-sdk' : 4.5.0

To Reproduce
Steps to reproduce the behavior:

1. I able to reproduce it on any test stream for example " https://bitdash-a.akamaihd.net/content/MI201109210084_1/m3u8s/f08e80da-bf1d-4e3d-8899-f0f6155f6efa.m3u8 "
2. Click on 'cast button'
3. Select device
4. See error

Expected behavior

Hi, I using the latest version and I've the same error.

Do you've any solution?

[Jsepr]

I had the same problem and solved it by providing an imageUrl when casting, it seems like there is no check that imageUrl is provided even though it's optional, which gives the error when it tries to parse it.

react-native-google-cast/ios/RNGoogleCast/RNGoogleCast.m

Lines 235 to 240 in f89405e

	[metadata addImage:[[GCKImage alloc]
	initWithURL:[[NSURL alloc] initWithString:imageUrl]
	width:480
	height:360]];

Btw I can't reproduce the iOS application crash with media streams listed above, plus example app is playing m3u8 files from
example datasource without problem, so problem is probably the image mentioned above

imageUrl is now optional since 3.4.0. If there's still an issue with casting an m3u8 (HLS) stream, please comment in #93
