Video Playlists and Format Question

MythTV Channel - development
Hi,

I have got my MythTV channel working now against my MythTV installation.

However, when Myth sets up a recording for streaming, it presents the results back in playlist files m3u

1st it returns a m3u with 2 choices on low and higher bandwidth
selecting one of the redirects in 1st

2nd returns a list of 'n' .ts urls representing the transcoded format.

I can't, however, seem to get the Plex Server to recognise the URL of either the m3u or ts formats to add as the media url for VideoClipObject.

Any suggestions pls.

Thanks

Paul

The plugin framework handles m3u playlists using the HTTPLiveStreamURL() callback. You should be able to implement your code something along the lines of:


<br />
stream = VideoClipObject(<br />
	items=[<br />
		MediaObject(<br />
			parts=[<br />
				PartObject(<br />
					key=HTTPLiveStreamURL(HI_RES_URL.m3u)<br />
					)<br />
				]<br />
			),<br />
		MediaObject(<br />
			parts=[<br />
				PartObject(<br />
					key=HTTPLiveStreamURL(LO_RES_URL.m3u)<br />
					)<br />
				]<br />
			)<br />
		]<br />
	)<br />



Adding them both as MediaObjects to the same VideoClipObject will allow the Plex client to choose the appropriate quality based on global settings.
