[lgwebos] mediaPlayer and mediaStop channels state not updated

[lolodomo]

When handling a channel command, the channel state is not updated.

PR #7355 is fixing the case of the power channel.
Another PR might be necessary for other channels.

[lolodomo]

After first checking, I was wrong, it is working well at least for the following channels: volume, mute channel and appLauncher. It is due to the subscriptions used for these channels.

[lolodomo]

It also depends on whether autoupdate="false" is set or not on the item.
I think only the channels power, mediaPlayer and mediaStop require a fix.

let us not discuss the power channel in too many threads.

MediaControlPlayer see comment: // TODO: playstatesubscription
I have not found out how to listen for those play states yet in the api

[lolodomo]

For mediaPlayer, I tried few commands to get the player status but with no success.
So we have no known way to detect player commands from external devices (like TV remote control).
At least, we could try to maintain a coherent state between mediaPlayer and mediaStop channels, when used only from openHAB. This is better than nothing, but of course not perfect.

Is there any hope this will be fixed? I would love to get a reliable play/pause state from the tv to control the living room lights...

Wasn't the playstate subscription added to the original SDK? ConnectSDK/Connect-SDK-iOS@5d1695a (Android Link doesn't seem to work...)

[lolodomo]

@sprehn : do you see something in the provided link that could help identify the URL to subscribe to?

[sprehn]

hi, no I don't find it in there and this is just the error handling piece. Connect SDK was trying to implement a universal abstraction, not only for WebOS, but also for ChromeCast, AppleTV etc. - so it does not mean this works in WebOS.
@lolodomo you are correct, if we know which url to subscribe to, we could do it. But I don't.

[lolodomo]

As there is no identified solution to determine the playback status, I mark this issue with the tag "won't fix".

[lolodomo]

... and I even close it.

Any more development on this? It's a shame that this isn't currently possible.
