[WIP] Add SSDP support

[hazcod]

Add uPNP/SSDP support, so that discovery and heartbeat of telly works.
This will fix the 'tuner not available' errors.

[tombowditch]

Looking good so far, will take a look myself later.

[lellimecnar]

I'm pretty sure this is the issue I'm having. I'm looking forward to this fix! 😁

[handyhelp]

any news about this issue? I get the error too tuner not found on my synology nas 😊

[hazcod]

This needs to be done in a channel, which honestly I am not familiar with.
You worked with it before @tombowditch ?

[hazcod]

@tombowditch this should work theoretically (looking at other work like https://github.com/OpenViX/HRTunerProxy/blob/master/plugin/ssdp.py), but plex marks it as dead.
Ideas?

Its not responding to M-HEAD from plex, thus plex marking it as dead.

Reducing interval time in 'sendAlive' from 300s to something smaller seems to work for me (i'm using 15s right now)

[hazcod]

Aha! Will try that tonight

[hazcod]

@japaol touch test && go build main.go && ./main -playlist=test with aliveTick := time.Tick(15 * time.Second) or even 10s on every interface will not show telly in the search in Plex. What did you do?

[japaol]

@hazcod I had to specify a UUID as device Id and a listen interface. I think i have not touch anything else.

[hazcod]

I tried with go build main.go && ./main -playlist=test -listen=192.168.0.167:6077 -deviceid="2650EB7E-1768-4503-9FDA-E7377F3A640C", but still nothing.

[japaol]

@hazcod Mine is ./telly -logrequests -playlist Movistar.m3u -streams 99 -listen 192.168.1.98:6077 -deviceid a5288e73-409f-4191-b02d-2bf963433d7e. I compiled telly with make, in raspbian.
I noticed that Windows shows telly as a multimedia device, in Networking, so it seems that SSDP is working well. My Plex Media Server is running on Windows.

[hazcod]

But did it pop up automatically when adding a new tuner under Plex?

[japaol]

I think i have managed to get it working.
Looking in another projects that emulates HDHomerun, like https://github.com/geertbongers/tvhProxy or https://github.com/TheJF/antennas, it seems that some models of HDHomerun uses its own discovery protocol on port 65001, and others models uses SSDP. So, changing the ModelNumber in the device.xml could make a change in Plex.
Furthermore, the DeviceID of the HDHomerun has to be a eight char Id, but in SSDP we need a UUID.
So this is what i have do:
Changes in code:

• ModelNumber to HDTC-2US
• DeviceId fixed to 12345678
• Reduce alive interval to 15s
  Run telly specifing a valid UUID as deviceId

With all of this, Plex detects telly at the first alive notification sent.

[hazcod]

@japaol can you try with this build? @tombowditch do you still have an IPTV subscription to test?

telly-build.zip

Edit: web gui still shows;

[tombowditch]

@hazcod I do, yes! :-)

[japaol]

It works, but I think that Plex search for the word HDHomerun in the friendlyName to detect it as a valid HDHomerun tuner.
In all tests I made, if I left the friendly name as default telly, Plex found nothing. But it I change to telly HDHomerun Plex starts to detect the tuner.

Note: between each tests, i had to restart Plex Media Server because sometime it gets stuck and says that no tuner available (i think that it is related to some internal timers or cache)

This one is the instance that I'm using since weekend.

[hazcod]

Committed the change to the friendly name (I remember seeing this myself), will test tonight.

[hazcod]

Ok, so I finally got it to work if I restart Plex after adding telly!
@tombowditch can you test as wel? So we can merge,

[myusuf3]

I tested it! it works.

[hazcod]

@tombowditch I will go ahead and merge it, but will not release a new version. I'll leave that up to you.

[tombowditch]

All good! Many thanks for your work all. I will release a new version later today.

[hazcod]

Thanks Tom, and thank you for your input @japaol !

[myusuf3]

@hazcod how do you keep guides in sync, I have guide working for a couple of days then they get old. I am using p2.xml method. ideas?
