Subtitle Extract plugin not working

[babrah]

I installed Subtitle Extract plugin. On triggering the "Subtitle Extract" Scheduled Task, it seems like subtitle extraction keeps failing.

Failure Log: https://pastebin.com/RAGTTQd1

I was able to find one instance of successful subtitle extraction from the logs, is there anyway to tell if extraction was successful for a file from media info/metadata information?

Would be very helpful if someone can help me understand why the extraction process is failing so often. Thanks.
