UnicodeDecodeError - video/audio sync issue

[michaeltoohig]

When playing certain files I get an error which causes either a BrokenPipeError or the following:

DEBUG       Executing ffmpeg -hide_banner -i data/Jesus Christ Bruce...-oLMkUKAiVDY.mp4 -filter:a [in]apad[out] -s 12

Play continues but these files can cause video/audio sync problems which can be very small or adds up over an hour or two to be noticeable.

All files were downloaded with youtube-dl and I was just playing them in a loop to see if this type of error would occur; only a few of the files seem to cause the error.
