Channel to View VLC Stream

Dev Community Dev/API Corner
1
Essentially what i'm trying to do is create a plex plugin that will allow me to watch a live stream.
 
I am currently using vlc to successfully tune my tvtuner and can stream to other vlc clients. I have the best success using an RTP stream with no transcoding simply providing the ts encapsulation as it is received over the air. 
 
cvlc atsc://frequency=605029000 --sout '#rtp{dst=10.0.1.8,port=5004,mux=ts,ttl=1}' --sout-keep -d
Using a separate instance of vlc I can open the network stream using rtp://10.0.1.8:5004 and it streams butter smooth.
 
 
I have also successfully streamed content using HTTP Live Streaming (HLS) as designed by Apple:

 

cvlc -I dummy --ffmpeg-hw atsc://frequency=605000000 :live-cache=5000 --sout='#transcode{vcodec=h264,vb=200,fps=30,scale=.5,venc=x264{aud,level=50,keyint=15,bframes=0,ref=1},acodec=aac,ab=40,channels=2,samplerate=22050}:duplicate{dst=std{mux=ts,dst=-,access=livehttp{seglen=30,delsegs=true,numsegs=20,index=/var/www/stream/live.m3u8,index-url=content/live-######.ts},mux=ts{use-key-frames},dst=/var/www/stream/content/live-######.ts,ratecontrol=true}}' 

This generates a .m3u8 file which is dynamically updated as new clips are processed. It is accessible in safari on the iphone.

 

What I'm trying to do is create a plugin that will grab that live feed (preferably an rtp stream) and transcode it on the fly for my clients.

 

 

I have created a plugin which I thought would essentially look at that address (10.0.1.8:5004) and transcode it for whichever client I am using. However, I can't get it to actually find the stream!

You won't have much luck with a RTP stream. PMS doesn't support it. Yes, FFMPEG does but PMS does not. Oh well. In theory, the HLS stream should work but you're constructing your VideoClipObject improperly.  The current plugin framework is designed around URL Services. In your case, an URL Service isn't really going to add much benefit but going without one makes the __init__.py look a little more confusing.

When you're not using an URL Service, you must not set the 'url' attribute of the VideoClipObject. Instead you need to set the "key" and "rating_key" attibutes.  Usually the key is a callback and the rating_key is a unique string to identify the video. Often the URL can be used as the rating_key. I just re-wrote the channel for Sesame Street using this method. It uses MP4 videos rather than m3u8, but the concept for structuring the VideoClipObject is pretty much the same.
