Methodology
We tested the remaining seven video players Google Pixel 1, Android 8.0, Chrome and iPhone 7+, iOS 10.3.2, Safari. A series of tests were undertaken including whether the mobile video player supported captions and / or audio descriptions, whether the volume of the video player could be modified and whether color contrast was sufficient. A video player was deemed to include a showstopper if any of the following occurred:
Video could not be played – not a failure of WCAG2, but deemed a significant failure;
Video could not be paused) – failure of WCAG2 Level A Success Criterion 2.2.2 Pause, Stop, Hide; and/or
Video crashed the browser– not a failure of WCAG2, but deemed a significant failure.
Three video players: Kaltura, MediaSite and YouTube contained embedded show-stoppers. The remaining four video players were: AblePlayer; JW Player; OzPlayer; and Plyr.
