The previous eventyay version had a dropdown menu for different languages with the source of the sound coming from Youtube. Implement the same here.

Task Breakdown:
Create input fields that allow the admin user to add languages and their corresponding YouTube URLs. Additionally, provide a button to enable the admin to add more language and URL pairs dynamically. Also, create a dropdown menu on the streaming page where users can select different audio translations.

TODO in the web app:

• Add Dynamic Language and URL Input Fields
• Create a Button to Add More Languages and URLs
• Create a Dropdown Menu for Audio Translations/ in the streaming page template
• Populate the dropdown options with the languages added by the admin
• Implement a method to handle the selection of different audio translations

The functionality should work in the way that the video source always stays the same no matter what language is choosen. But: When the user clicks on another language the audio source changes.

Right now this feature does not yet work as required. In order to sync the audio and different video channels the previous system deactivated the video controls.

The audio that is currently playing needs to be added to the currently playing live stream. This way we can achiev a kind of synchronization. -> So, currently playing video + currently playing audio of a live stream. This is the solution in order to achieve sync.

The user should not be able to rewind or move forward. The video should always display "current". Therefore we can only fully test this feature using live streams.
