HLS Stream crashes Roku

Dev Community Dev/API Corner

I have been working on some issues on the USTVnow plugin and I've noticed that the streams I am getting consistently crash the Roku and subsequently the Roku will need to reboot itself. The streams work perfectly on the other clients I've tested them on. Here is what my MediaObjectsForURL looks like:

def MediaObjectsForURL(url):	
    video_url = HTML.ElementFromURL(url).xpath('//video')[0].get('src')
    return [
  	MediaObject(			
		audio_channels = 2,
		parts = [PartObject(key=HTTPLiveStreamURL(url=video_url))]
	)
    ]

Here is what the m3u8 playlist looks like:

#EXTM3U
#EXT-X-VERSION:3
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=2383872,CODECS="avc1.66.41,mp4a.40.2",RESOLUTION=1280x720
chunklist-b2383872.m3u8?wowzasessionid=581324366&key=RDJDNDAT652383D231B8805FB9D5B35AB9FB7583E82

I don't see any errors in the Plex Logs on the server or on the Roku. The Roku logs are reset once the Roku reboots it looks like. Any tips on how I might be able to debug this? Thanks!

Maybe the Roku can't handle relative paths?

I'd suggest you try using a callback with the @indirect decorator, that usually helps when the paths in the m3u8 list are relative.

For an example, see https://github.com/plexinc-plugins/Services.bundle/blob/master/Contents/Service%20Sets/com.plexapp.plugins.svtplay/URL/SVTPlay/ServiceCode.pys#L78

I figured out what was causing the Roku to crash. The Roku can't handle a playlist file with multiple paths (which seems really odd).

Maybe it is this problem then:

It looks like the line endings are already .
