Understood. I recognize your name from other posts. I'm also commenting
on the follow-up post by 'mythtv at hambone' (which I seem to have missed
but found on Gossamer-Threads when reviewing your original post.

So, James, I made the assumption that you lost the icons after updating to
0.27, although you didn't mention your version in the 1st post. Since your
'ls data/tv_icons/' below shows icons and assuming they match the existing
chanids, then I'm out of ideas for you. I did notice that all my icons are
jpg files, not png but have no idea if that's a problem.



For mythtv at hambone and for James because GetChannelIcon failed:

Are you running mythtv-setup as the same user that runs mythbackend?
(mythtv at hambone said yes)

If you're running mythtv-setup (for example) as 'jam' then the icons would
be saved in ~jam/.mythtv/channels. But in 0.27, the backend (and
therefore the Services API) should get them from ~mythtv/.mythtv/channels,
unless you run your backend as some other user.

That's bad. You can look at what fails in your backend log if you
start with "upnp" logging, or use: "mythbackend --setverbose upnp"
on a running backend. Good log entries look like these:

     ExtractMethodFromURL(end) : GetChannelIcon : /Guide
     ServiceHost::ProcessRequest: GetChannelIcon : GET /Guide/GetChannelIcon?ChanId=1021 HTTP/1.1
     HTTPRequest::SendResponse( File ) :200 OK -> FDF9:123:456:1::789 (I'm using IPv6)
     SendResponseFile ( /home/mythtv/.mythtv/channels/cbs.jpg )
     HTTPRequest::TestMimeType(/home/mythtv/.mythtv/channels/cbs.jpg) - type is image/jpeg
     SendResponseFile : --- size = 0, offset = 4569, sent = 4569

It could be that cached icons are working today, but changes/additions will be missed.

Agreed, the above get generated from the downloaded icons.

Good.

That should fail (it's invalid without GetChannelIcon (or one of 3 other end-points.)
