destreamer: Error on the prerelease branch

I was testing the speed of the prerelease when I got the error

[ERROR] stdout maxBuffer length exceeded

[FATAL ERROR] The aria2c rpc server crashed with the previous message

This happened after I downloaded about 3 files that I supplied the links via the file.txt input.

EDIT

Always crashes with the error above after downloading 2 whole videos and finishes the video segment of the third, about when starting to download the audio segments.
