VTT Mime Type fails upload

Reported by: birgire's profile birgire Owned by:
Milestone: Priority: normal
Severity: normal Version: 5.0.1
Component: Upload Keywords: has-patch
Focuses: Cc:


The text/vtt is an allowed mime type but doesn't match the text/plain from the $real_mime in wp_check_filetype_and_ext() and after 5.0.1 that function returns:

Array ( [ext] => [type] => [proper_filename] => )

but did return before:

Array ( [ext] => vtt [type] => text/vtt [proper_filename] => )

This was reported by Prast here.

Similar has been reported for CSV in #45615

I suspect the same might be true for some of the other supported text formats:

'csv' => 'text/csv',
'tsv' => 'text/tab-separated-values',
'ics' => 'text/calendar',
'rtx' => 'text/richtext',
'css' => 'text/css',
'htm|html' => 'text/html',
'vtt' => 'text/vtt',

Thanks for the report - yes I believe you're right about at least some of those other formats also. There are further complications as well. I like your approach of adding an extra entry to the wp_get_mime_types array, that might help with some of the other issues. I'm working on testing some variations.
