 Summary of the bug:
 FFmpeg's file: protocol does not follow the spec with respect to the
 number of forward slashes after the sheme (see
 https://en.wikipedia.org/wiki/File_URI_scheme). FFmpeg appears to expect
 no forward slash after the "file:" whereas the file: protocol is supposed
 to have one, two or three slashes after the "file:" string, three being
 the most "correct".

 How to reproduce:

 This works even though it is not a valid file url:
 ffmpeg.exe -f lavfi -i smptebars -t 30
 file:C:/Users/username/Desktop/smpte.mp4

 This doesn't work despite being a valid file url:
 ffmpeg.exe -f lavfi -i smptebars -t 30
 file:///C:/Users/username/Desktop/smpte.mp4

 This makes ingesting file urls produces by other software slightly tricky.
