Methodology
Initially we conducted testing on Google Chrome version 61.0.3163 under Windows 10. A series of tests were undertaken including whether the video player supported audio descriptions, whether the transcript was accessible to the keyboard and whether the volume of the player could be modified. Video players were deemed to include show-stoppers if any of the following occurred:
- Audio plays automatically; unless the user is made aware this is happening or a pause or stop button is provided – failure of WCAG2 Level A Success Criterion 1.4.2: Audio Control);
- Video contains a keyboard trap (i.e. users cannot escape from the video using the keyboard) – failure of WCAG2 Level A Success Criterion 2.1.2 No Keyboard Trap; and / or
- Full-screen video contains a reverse keyboard trap (i.e. users cannot escape from full-screen mode using the keyboard) ) – failure of WCAG2 Level A Success Criterion 2.1.2 No Keyboard Trap.
At the conclusion of Round 1 testing only the following eight video players remained: AblePlayer; JW Player; Kaltura; OzPlayer; Panapto; Plyr; and YouTube embed.
