RNVideoTrimmer.swift Fatal error > Unexpectedly found nil while unwrapping an Optional value

[oguzhnatly]

Current Behavior

I was able to obtain ProcessingManager.getVideoInfo and the function returns a successful result, however when I try to compress the file, I receive Xcode errors and the app crashes unexpectedly.

I believe I have successfully linked the required libraries to our Xcode, otherwise there would be an error at runtime.

Expected Behavior

I could compress the file as expected.

Any update on this ? getting same error.

Also getting this error. Works fine on Android though. getVideoInfo works fine on iOS and Android.

Okay, I finally found out what the problem was for me.

The response from ProcessingManager.compress differs on Android and iOS. On Android you receive an object with source (just like the image). On iOS, the result is only string (the path).

Also, ProcessingManager.getPreviewForSecond was also causing errors so I deleted (didn't really need it).

Hopefully, this solves some headaches. 🙂
