HLS audio streaming

Dev Community Dev/API Corner

Hey guys, I'm kinda lost in this plugin development. The online docs are insufficient and I've been looking at the framework it self for reference, but I'm having one issue in particular thats bugging me. 

def SpilaRas1():
	mc = ObjectContainer()
	url = "http://sip-live.hds.adaptive.level3.net/hls-live/ruv-ras1/_definst_/live/stream1.m3u8"

track = TrackObject(
	url = url,
	key = HLSURL(url),
	title = "RAS 1",
	artist = "RUV",
	summary = "BEIN UTSENDIND",
	album = 'Hvad stendur her?',
	duration = 999,
	rating_key = 0,
#	thumb = image,
#	art = image
)
media = MediaObject(

	protocols		= Protocol.HLS,
	bitrate			= 44100,
	parts 			= [PartObject(key=Callback(PlayLiveAudio, url=url, ext='ts'))],
	container		= Container.MP4,
	audio_codec 	= AudioCodec.AAC,
	audio_channels	= 2
)
track.add(media)
mc.add(track)

return mc



def PlayLiveAudio(url):

return Redirect(url)

The damn thing won't play, neither in PHT nor the Web interface. 

 

Am I overseeing something?

I'm not 100% sure how HLS audio-only streams are handled but, assuming they work as expected, you're using the key & rating_key properties incorrectly.

Take a look at the code for the PlexPodcast channel for an example of how to pass audio files without using an URL Service.

I've taken a good look at what you mentioned, and I've added this recursive Callback. But now there seems to be a different problem with a route. I'm not quite familiar with routes.

How do routes work?

The routes are used to provide a more RESTful interface for the channel methods.

In your case, I don't think that's its really necessary. You'll notice that there are no routes used in the PlexPodcast channel.

It would be a good idea to add the @handler decorator to your MainMenu(). That will allow you to remove the PrefixHandler lines

Plugin.AddPrefixHandler(
		PREFIX,
		MainMenu,
		TITLE,
		ART,
		ICON
	)

I would also suggest removing the ViewGroup definitions, since most (if not all clients) ignore viewgroups that channels provide anyways.

Plugin.AddViewGroup('stationList',
		viewMode 		= 'WallStream',
		mediaType 		= 'items'
	)

I've done some improvements.

This is a log for one request to play a stream https://gist.github.com/anonymous/9752019

and this is my current plugin: https://gist.github.com/anonymous/9752043

But to no avail, nothing plays.

I made some changes and comments.

Thanks for taking your time to help me with this. Are there any rumors speculating updates on the API and docs?

As I understand it, updates to the API and docs are planned but (as with all things Plex), there are no public timelines.
