Closed Caption Button and Dynamic Language Change for Captions

[HamzaIsrar12]

Hi Pier,

I would like to add a closed caption button to the YouTube player to enable/disable captions dynamically. Additionally, I want to allow users to select the available languages for captions.

I already have access to the available languages through an internal API, but I'm facing an issue with changing the caption language or enabling/disabling captions after the player is initialized.

Issue/Blocker:

• It seems that changing the caption language or toggling captions is only possible through the IFramePlayerOptions, which can only be set during the player's initialization.
• The library does not support reinitializing the player after it’s been created.
• Destroying and recreating the player to apply new IFramePlayerOptions results in a glitchy experience.

Question: Is there a way to dynamically update the caption settings (enable/disable and change languages) without destroying and recreating the player? Or, is there a recommended solution to handle this more smoothly?

Any insights or workarounds would be greatly appreciated! Thank you.

I suggest to

1. finding a way to do this with the IFrame Player.
2. try to replicate that in the library.

If 1 is possible but 2 is not, we can work on a solution to enable it.
