i'd blame a combination of youtube-dl and maybe yourself ;) i've never had
that issue with ffmpeg that wasn't caused by my own error. I'm using Ubuntu
16.04, but never had a file path issue on any O.S that wasn't fixed by
double quotes or escaping characters/spaces.

I have some videos that I downloaded with youtube-dl that look like they
have similar filenames. I tried a similar ffmpeg command and all was well:

ffmpeg -i 'Compton MC Kendrick Lamar Interviewed By Hima From Das Racist -
Rap Show - Episode 1-ev8Cm7yiSvY.mp4' -vn -c:a libmp3lame -ab 320k -ac 2 -y
