Update metadata without interrupting stream. #25

Closed strelniece closed 3 years ago

strelniece commented 3 years ago

Hi,

I cast a livestream (radio channel) to my chromecast audio and update the metadata whenever there is a new program, the stream itsself contains no metadata, unfortunatly...

Since the last update, it is defenetly doable, thank you! but there is a very short pause when the node updates.

Is it possible to update metadata only, without interrupting the audio stream? I've tried a couple of things, but so far no luck...

I don't follow what you're trying to do. With the new model, the Cast connection is maintained permanently, and the Cast device will send its updates in a push manner (i.e., you shouldn't be polling for information). Am I misunderstanding what you're doing?

Hi, Sorry, not always easy to be clear in your native language, and even less in another...

I live stream my favourite radio station, their stream is audio only, no metada at all.

So the metadata has to be added by it self and updated every time a new program starts.

So far I haven't found a way to update the metadata without also including the live-stream url so the stream will make a short pause, it is very short, less than a second, but rather annoying.

So is it possible to update only the metadata, without affecting the live stream?

I hope I managed to explain better now.

Also, a big thank you for implementing the permanent connection, before that it was defenetly not possible to at all to do this...

Got it. No this isn't possible that I'm aware of. Every MEDIA command will start a new cast load. I am not aware of any way to load additional metadata after media has loaded.

I was afraid that was the case...

I was digging through Googles documentation and if I understand it correctly that there is i new SDK, CAF, where it's possible to update metadata only.

Any chanche you will update the node to CAF?

i8beef commented 3 years ago

Nope. The actual cast implementation here is all handled under the hood by a third party library (castv2, thus the node name). CAF is a completely different animal which, to my knowledge, no one has written a node library to support yet.

Closing as there's not a way to enable this functionality.
