Channel Icon Download System

As of 0.21, MythTV includes a channel icon download system in mythtv-setup which will attempt to automatically download icons for channels in your database from services.mythtv.org. If it cannot find an icon it will present you with a list of options, an the ability to define your own search parameters.

To configure icon downloading in mythtv-setup:

  • run "mythtv-setup"
  • select "Channel Editor"
  • click on "Icon Download"
  • select either "Download all icons.." or "Rescan for missing icons.."

Universal Location

Starting with version 0.27, a single location for channel icons is used. By default, it will be in the .mythtv/channels directory of the user that runs mythbackend. Typically, mythtv.

As of [6d10afe]cgitgithub mythweb also works. Check it's .../data/tv_icons directory. The directory must have read/write permissions for the user that runs the backend and the group used by mythweb. E.g. mythtv:www-data, mode 775.

The Services API (e.g. <backend>:6544/Guide/GetChannelIcon?ChanId=1021) endpoint works with this feature as of [85462fb]cgitgithub.

Symlinks added for prior MythTV versions, duplicate channels directories and any ChannelIcons directories and their contents can be removed. Obviously after copying icons to a new directory as required.

Pre 0.27 Instructions

By default the icon will be downloaded to the /home/<user>/.mythtv/channels directory. This is not very friendly when you have multiple frontends and wish them all to share the icons. One method to get around this is to use a symlink for this directory that directs to a network located directory that all your frontends have access to, say /var/mythtv/channels for example.

Before downloading the icons, do the following, or similar as per your distribution:

rm ~/.mythtv/channels -rf
sudo mkdir /var/mythtv/channels
sudo chown <user>:<group> /var/mythtv/channels
ln -s /var/mythtv/channels ~/.mythtv/channels

You will want to run

rm ~/.mythtv/channels -rf
ln -s /var/mythtv/channels ~/.mythtv/channels

for all the users that can run MythTV as well.

Channel Icon Sources

One of the best sources of channel icons is http://www.lyngsat-logo.com/ . There, you can browse the available icons and choose those appropriate for your system. However, doing so can be a lot of work (requiring many page hits and a lot of time). Once downloaded you should put the resulting JPEG files into .mythtv/channels/ for the user running the front-end. To add them to a channel you will need to run mythtv-setup and go to the channel editor and specify the icon file name for each channel.

Another source of channel icons is http://www.iconharmony.com/ which is targeted for icons for the harmony remote. Some of the available icons are more stylized than the official icon (the person running the site is a graphic artist). As with the previous source, finding an appropriate icon can be a lot of work.
