Filename with single quote fail target quality with temp set to name with quote

[luigi311]

If you try to encode a video with a single quote in the name of it target vmaf will fail if you name the temp folder the same name with the quote. The following error along with the backtrace version

Running without target quality it encodes perfectly. Looking at the error it specifically points to a vmaf function.

looks like the error also happens if you dont specify a temp folder so it uses the generate one, if you have a quote in the output though when it runs the final vmaf calculation. So right now the only work around is to make sure the output doesnt have a quote in it because the final vmaf, --vmaf, seems to be force when using target_quality, see #790 and you dont specify a temp folder with a quote in it.
