fail stack trace is empty when getMediaInformation method receives a parsing error

[tanersener]

getMediaInformationExecute method responsible of extracting MediaInformation calls wrong MediaInformationJsonParser method on Objective-C API we have for apple platforms (iOS, macOS, tvOS). Because of that, the parsing error is lost and not saved in failStackTrace.

It is a big deal for us since failStackTrace field was introduced to save those parsing errors.

All FFprobeKit.getMediaInformation methods are affected from this on v4.5.1.

fixed on the development branch.
