loadTranscriptByUrl static method

Future<Transcript> loadTranscriptByUrl({ required TranscriptUrl transcriptUrl, dynamic timeout = const Duration(seconds: 20), })

Load a PC2.0 Transcript from a file. Transcripts can be either JSON or SRT (SubRip) format. The mime type is used to determine if either the JsonParser or SrtParser is used.
