changed wording of raw mp4 file to media file as we can import variety of formats both audio and video
<ng-template ptTemplate="customHtml">
<ng-container i18n>
You can import any URL <a href='https://rg3.github.io/youtube-dl/supportedsites.html' target='_blank' rel='noopener noreferrer'>supported by youtube-dl</a>
- or URL that points to a raw MP4 file.
+ or URL that points to a media file.
You should make sure you have diffusion rights over the content it points to, otherwise it could cause legal trouble to yourself and your instance.
