Lost most channel logos with 1.8.1.4

[gratefuldad2000]

Hi @garyan2,

The latest release has been a bit a bit unstable for me. While it seems to download the EPG data correctly, most (but not all) of my channel logos have disappeared, and I have hundreds of them in the logos folder. I tried clearing the cache and removing all logos through the UI, which caused the channel names to show up, but the problem came back after the next update. Trace.log shows no errors or warnings:

Code: Select all

In the server.log on the other hand I noticed a NullRef, which is probably the root cause of the problem:

Any ideas what could be wrong?

Thank you!

[garyan2]

The errors in the server.log are for program images. For logos, the function that will show in the log file with the exception would be something different.

Logos are provided over HTTP via the service... is your service running on whichever machine created the mxf file?

Take a look at the status webpage at http://localhost:9009/ to see how many logo requests you have received and how many have been serviced.

[gratefuldad2000]

Hmm, 0 requests and 0 serviced. Why would that be?

I had logos for every channel before the upgrade. Now 90% are blank.

[garyan2]

To test your service, use a browser and go to http://localhost:9009/logos/<logo_filename.ext>. Just pick any file in your /logos folder and see if it downloads the logo and/or the status page updates with a request number.

[gratefuldad2000]

That all works. However, I noticed that only the custom _c.png logos end up in the guide even though it's set to use the dark background logos.

[garyan2]

Custom logos are embedded in the mxf file so they will always show if your configuration has 'Include station logos in .\logos folder' enabled. It sounds to me like you don't have 'logos for dark backgrounds' selected, but have 'none (custom logos only)' selected.

Note if you change that setting, you will have to run another update and import it into WMC before the changes take effect.

[gratefuldad2000]

Well, it is set to 'logos for dark backgrounds' and they do show up in the epg123 UI so I ended up dragging all the dark logos to the custom logo field for all my channels, which created the _c.png files in the logos folder and now they do show up as expected. Crisis averted.

No idea why the dark logos wouldn't work though. Should there have been _d.png files for each or where do they come from? BTW, I noticed a ton of logos that start with 's' and have a guid in the name. I don't remember those from before.

[garyan2]

I think you are just masking an underlying problem in your setup by making them all custom logos. If your browser can get the logos, WMC should as well. If you are able to download program images in WMC, then you should be able to download logos.

The "<callsign>_d.png" (and other _?.png options except _c) are no longer used. The logos starting with "s" are also no longer used. That is why I added a button in the configuration GUI to [Remove Orphaned Logos] and remove them from the /logos folder.

The benefit of not using custom logos for everything is if the station changes its logo, the change in WMC will be immediate. I just had this on one of my OTA stations whereas the broadcaster changed from "LX" to "LXHOME" with a new logo. With OTA, the callsign does not change so the old methods would not have worked.

Makes sense. The thing is that the browser can only get the logos from the logos folder, and after removing the orphans there are only the custom ones left. So what I don't understand is where the dark logos should be coming from. There is an sdlogos folder next to it but that's empty. Asking the browser for usahdp.png or usahdp_d.png for example says it can't find it, but asking for usahdp_c.png works because it exists in the logos folder.

[garyan2]

There are only custom logos left in the folder because you replaced all the downloaded logos with custom logos. The filenames from SD will be 32-characters long which is actually the md5 value of the image.

So, take any one of your stations and delete the custom logo. Make sure the configuration GUI is set like the below, and click [Save & Execute].

The trace.log file should have an entry saying it was downloading 1 station logo, and that station logo should then be in the /logos folder.

[garyan2]

Give 1.8.1.6 a try. You may have been having a related issue to another user, though if you were able to get logos on a browser then it is definitely not the same issue.

[NOYB]

Me too. Lost non custom channel logos and program images.
Restart WMC. Not resolved.
Run EPG123 configurator (UAC prompt to run as admin; opened a command prompt and started some service).
Restarted WMC. resolved. Channel logos and program images are now displaying.

Windows 8.1 WMC
EPG123 1.8.1.3

Also
Windows 11 WMC 8.9.1
EPG123 1.8.1.3

[garyan2]

So your service was failing to start as well... the UAC prompt was to start the service which the configuration gui checks for when you open it.

This is why I released 1.8.1.6 to help with this.
