MythTV in 12.04

[B34N]

MythTV runs nicely on the core but the backend server cannot be found by the frontend on my MD. I also noted that the backend server cannot be found by the MythTV frontend on my android device. I was wondering if anyone else is there anyone using MythTV in 12.04 and able to connect to the backend from a device other than the core.

I was having that issue also. I am not sure if it is related or not because I upgraded my install Myth to .27 and it may have reset some of the default settings that should be there normally. But in MythTV setup, in the general section. The backend IPv4 was set to the local loopback(127.0.0.1). I found somewhere on the internet that said that the backend only responds to requests on that ip address. So I changed the backend ip to the local LAN ip address(default: 192.168.80.1). After that I was able to access it on my MD as well as my phone using mythtv frontend.

can you please file a ticket, so we can fix the issue?

I submitted the ticket. Changing the backend server from 127.0.0.1 to 192.168.80.1 worked for the MythTV front end on my Android device but not for the MD. I'll keep testing to see if I can determine the reason.

I upgraded my install Myth to .27

How did you upgrade to .27? I am also interested in the latest version, especially with the Unicable / Satellite Channel Router / DIN EN 50494 patch https://code.mythtv.org/trac/ticket/9726

[ata-lmce]

I updated to .27 by adding the myhtbuntu repositories

deb http://ppa.launchpad.net/mythbuntu/0.27/ubuntu precise main
deb-src http://ppa.launchpad.net/mythbuntu/0.27/ubuntu precise main

ran the commands
sudo apt-get update
sudo apt-get install mythtv

Then I had to update the MythTv_Plugin by downloading the source for it and updating MythBackEnd_Socket.cpp to change the protocol from 72 to 77 and also the token from D78EFD6F to WindMark. I then recompiled MythTV_Plugin.so and copied that to /usr/pluto/bin

It has been working pretty well for me since then. I had to change a few other settings in the MythTv setup as well. To fill the guide, I changed the command mythfilldatabase to /usr/pluto/bin/MythTvDailyFillDB.sh and also added Job #1 back in to save the recordings to the linuxmce database.

Would you mind providing some patches and/or take over ownership of the MythTV integration ?

[ata-lmce]

I will definitely add some patches for some of these things when I am more confident that all my changes have not affected the system in any other way.

I am going through the code and finding where all this stuff is implemented when installed. When I find it all, I will update it and add some patches to the system to take care of it. There are a couple other things I had to get fixed also that help my install run better. I was also thinking about adding a couple device data fields to the MythTV_Plugin to allow someone to run any version of MythTV they would like. I am still in the early stages of that though to know how much work that would take and if it is even worth while.

I am not quite sure if I am ready to take ownership over the MythTV integration yet, but willing to help out any way that I can.

[Marie.O]

To not loose your work, why not attach a patch every other day or so to a trac ticket. That way, when you get hit by a Michael Bay explosion gone bad, we won't loose your work.

Seems to work.

I wanted to attach the plugin for version 0.26 but it seems we only allowed 192KB ;-(

Hey there ata-lmce!  I am, currently, one of the primary devs on the project.  I try to work with people regularly as they are prepping new features or bug fixes.  If you need any assistance let us know.  I'd be happy to help you to get things added/updated/fixed from this end.  So even if you do not wish to take ownership we would still welcome any contributions you can provide, especially MythTV related. 

J.

[ata-lmce]

Thanks for the support. I am going through the ticket system now to learn how that works so I can start with a lot of that and get some updates pushed out. I will let you know if I have any questions or need help with anything.

thanks again
