wpview: mejs: Playing one player inside the editor doesn't stop the other

[iseulde]

To reproduce, add two audio/playlist views to the editor, play one and play the other. The first doesn't stop playing.

avryl - this is the case with trunk but not previously? Is it because of the iframes?

[iseulde]

Right.

[wonderboymusic]

wp.mce.av.View.stopPlayers() works like a champ because it is triggered by an event with the MCE view - getting the view's iframes' players to signal back to outer space that they are playing will be .... a challenge.

Either we figure this out or decide we don't care.

I care to some degree as far as the built-in MEjs player goes, which I have a feeling is the only case we can control anyway. Ever-better emulation of the front-end is a good goal.

Fires an event to stop a media player when another one is clicked.

When creating audio and video MCE views, listen to the players within each iframe to capture the "play" event. When a player plays, pause the players in every other iframe sandbox.

Fixes #29384.

Hey wonderboymusic,

For my own enlightenment, was there another issue that my fix missed? Or some pattern that is preferred that I overlooked?

I only ask so I can approach things differently in the future.

• Don't want to stop all players, we want to know which one is playing and stop the others
• We want to bind to an actual "play" event, not hijack a random click
• We need to be able to separate MEjs sandboxes from other sandboxes, so that they only react to each other, not every iframe

Gotcha. I was figuring the play event part. Thanks!
