Frndly TV for Channels

Playground Custom Channels
#439

Thanks for the advice and tips, @Absenm !

#440

I had Frndly TV for Channels working fine but got a new router today and now it is no longer working. I am guessing it is a firewall issue. My setup:

Channels DVR running on a Raspberry 4
Docker Desktop on Windows 10

As I said, I installed a new router today which I believe is the issue. A recording failed, then I was not able to play any friendly shows through channels dvr, so I removed the friendly source and tried to reinstall it. Now, when I try to add it back I get the following error message:

invalid source url: Get "http://192.168.1.6:8183/playlist.m3u8?gracenote=include": context deadline exceeded (Client.Timeout exceeded while awaiting headers)

It appears docker is running: C:\Users\bpaul>docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
0763f5399779 matthuisman/frndlytv-for-channels "python -u ./app.py" 3 days ago Up 29 minutes 0.0.0.0:8183->80/tcp frndlytv-for-channels

Should the port say 0.0.0.0:8183->tcp like it is showing or should the 192.168.1.6 adderss docker desktop is running on be listed?

Any suggestions?

#441

Does this link load?

What is the IP of your desktop?

Maybe you need to setup static dhcp reservation for the dvr on the new router

#442

Thanks for the quick response! The IP for the desktop running docker desktop is 192.168.1.6. Yes, the link loads and provides:

Blockquote Mark_Loves_KensleyDVR UserUpdate: I think my issue is I just installed a new Mikrotik router and I'm sure there is something I have to do to make the Channels DVR server see my Docker container. Both are in the same network but live on different machines. I am learning very quickly that the Mikrotik router is not very idiot friendly.

This is the issue I am having. Do you remember the fix?

UPDATE: OK, I GOT THIS WORKING. No more connection time out errors. Here is the fix:

In Windows Defender Firewall, under "inbound rules", you need to set port 8183 and Docker Desktop Backend to "allow connections".

Been trying for hours to get this working in Channels. Got the Docker up and running no problem but cannot get it to load into channels. I put in this http://192.168.50.172:8183/playlist.m3u8?gracenote=include and I get this error message

invalid source url: parse " http://192.168.50.172:8183/playlist.m3u8?gracenote=include": first path segment in URL cannot contain colon
Very minor issue with URL entry on Custom Channels form
#445

Where are you putting it?

#446

You have an extra space at the beginning of the url. Right in front of the http.

edit: maybe the devs can add something to weed out / trim white space from urls.

Under Custom Channels, Sourse, URL

#448

Corrected that and now get this error

invalid source url: failed to retrieve m3u: 500 Internal Server Error
#449

When you view the Frndly docker for Channels webpage at http://192.168.50.172:8183
Does it look like this?

Channels Source 1

Stream Format: HLS
Refresh: Daily
Source URL: http://192.168.50.172:8183/playlist.m3u8?gracenote=include
XMLTV Data URL: (Leave Blank)

Channels Source 2

Stream Format: HLS
Refresh: Daily
Source URL: http://192.168.50.172:8183/playlist.m3u8?gracenote=exclude
XMLTV Data URL: http://192.168.50.172:8183/epg.xml?gracenote=exclude

If it does, you should inspect the Frndly docker container log for errors

#450

And if you do see that page as @chDVRuser described, what do you see if you go directly to the source url from a browser? Do you see the text of an m3u?

#451

Yes it does look like that . Here's the error log

When I click on the URL I get this opening in a new tab

Error: USERNAME and PASSWORD are required

#453

Make sure the docker contains the correct current Frndly username and password. Maybe you miss typed something doing your docker run.

docker run -d --restart unless-stopped --env "USERNAME=MY_EMAIL" --env "PASSWORD=MY_PASSWORD" --name frndlytv-for-channels -p 8183:80 matthuisman/frndlytv-for-channels
#454

Do I put my user name after USERNAME= and password after PASSWORD=? Do I also leave the " in?

#455

Yes leave the quotes. Replace MY-EMAIL with your Frndly username and replace MY_PASSWORD with your password.

Frndly was working fine. Suddenly showing 0 channels. I've deleted the docker image and container and re started. Tried to re-add to the sources and now all I get is "malformed m3u"
What am I doing wrong?
Here is error log

docker : Error response from daemon: No such container: frndlytv-for-channels

It sounds like you don't have the docker container pulled. You can't stop it or remove it if it does not exist. Try pulling the container and running it.

docker pull matthuisman/frndlytv-for-channels
docker run -d --restart unless-stopped --env "USERNAME=MY_EMAIL" --env "PASSWORD=MY_PASSWORD" --name frndlytv-for-channels -p 8183:80 matthuisman/frndlytv-for-channels

Make sure you use your Frndly user name and password.
