Hello,
I have a question about the Trusted Tester 503.4.1-caption-control 17.E<https://section508coordinators.github.io/TrustedTester/media.html>. It says, "User controls for captions are provided at the same menu level as the user controls for volume or program selection." Just so I'm clear, what does this requirement mean? Does it mean the CC and Volume buttons "functionality" to adjust the volume, mute or unmute and the ability to turn the captions on and off is immediately available on the control panel and does not bring up a pop-up window? I have some examples below:

Figure 1 Vimeo player control panel on an embedded video has a Volume and CC button.

Figure 2 Volume can be muted and unmuted by clicking the Volume button on the Vimeo player.

Figure 3 When you click the CC button it brings up a menu on the Vimeo player with Off and English (auto-generated) CC..

Figure 4 On this YouTube embedded player, the volume can be adjusted, muted, or unmuted and captions turned on and off by clicking the CC button. There are NO pop-up menus. The red line under the CC means the captions are on.

Figure 5 On this YouTube embedded player, when you press the CC button and the red line disappears, the captions are off.
When you press the CC button on the Vimeo player in the screenshots above, and it opens a dialog box where you can choose "Off" or "English (auto-generated) CC", is that a failure of Trusted tester 503.4.1-caption-control 17.E? If so, is there a list of video players that meet the criterion that I can share with our vendor?

Thank you,
Carmen
