WebOS has [some documentation](https://webostv.developer.lge.com/develop/specifications/streaming-protocol-drm#streaming-protocol) on which HLS tags it supports.

However, there is something I don’t understand. If I use third-party web-based library for HLS, such as `hls.js` or `shaka`, aren’t those specifications irrelevant? After all, the third-party library is a separate, independent implementation of the HLS protocol: these libraries have their own specifications of which HLS tags they support.

I would think that the WebOS documentation refers to it’s own implementation of the HLS protocol. If I understand correctly, [it has it’s own implementation of one](https://webostv.developer.lge.com/develop/guides/resuming-media-with-mediaoption#using-mediaoption-to-avoid-needless-preload).

But, e.g., in their sample app, `MediaPlayback`, although `shaka` is used there for playback, they send the user to [their documentation](https://github.com/webOS-TV-app-samples/MediaPlayback/tree/main?tab=readme-ov-file#media-playback) on HLS support.

My question is: if I use a third-party library, such as `hls.js`, shouldn’t I rely on their documentation for which tags and which browsers they support instead of the WebOS specification?

As you mentioned, the webOS platform has a native HLS player, and the webOS specification is for it. If you use a third-party player, only the decoding and rendering functionality of the webOS platform will be used. Therefore, you should refer to the documentation of your third-party player, such as hls.js, for the HLS tags it supports. Thank you.
