Your closed caption extraction is failing:
MCEBuddy.AppWrapper.CCExtractor → Error: In user_data: ustream->bitsleft < 0. Cannot continue.
→ Process exited with code 1000
ERROR> → CCExtractor failed to extract closed captions
ERROR> 2019-05-18T07:47:26 MCEBuddy.Engine.ConversionJob → Extracting closed captions failed
It looks like a corrupted recording.
If you can upload a sample of the failing file to our server we can report it.
In the meanwhile turn off subtitle extraction and then re-run it.
EDIT: With the next 2.4.11 release we’ve modified the flow it won’t fail the conversion of the closed captions have an error or are invalid, it’ll log a warning in the file and continue processing it.
