Seek video on iOS with react-native-reanimated cause randomly crash at launch and in release mode only

Bug

When the app launch first time and we’re trying to seek video, the app can(not always) crash with no error.

Debugging with sentry show:

C++ Exception RNSScreen N5folly4json11print_errorE

Debugging from xCode console show:

libc++abi: terminating with uncaught exception of type folly::json::print_error: folly::toJson: JSON object value was an INF when serializing value at "playableDuration"

When not trying to seek video, or remove react-native-reanimated app stops crashing.

Steps To Reproduce

1. Isntall react-native-video and react-native-reanimated v2.3.1
2. Launch app react-native run-ios
3. On App.js mount and video loaded call this.videoRef?.seek(x)

Expected behaviour

1. To not catch crash, especially with no errors

Reproducible sample code

onLoad() {
     this.videoPlayerRef.seek(...);
  }

<Video
     {...props}               
    onLoad={onLoad}
/>

Confirming that the issue is in the calculatePlayableDuration function, we’ve removed all the code (function + call) a couple of days ago and it just got through QA.
