Very low quality of Thumbnails on Mezzmo Kodi-plugin on Android TV Box

[jbinkley60]

Hi, since today I use Mezzmo and I am very happy with it.
But I have a problem.

I am using an Android TV-Box with Kodi, and there I am using the Mezzmo plugin.
Kodi is vanilla and even the UI from Kodi I use. But sadly something is not right with my Thumbails:

All is fine, the backgrounds, the actor pictures, etc. except the Thumbnail of the media is totally blurry and in bad quality.
I already tried to change the Options > Browsing Files > Thumbnail Sizes and set it there to 600x600 but even that did not look good.

So, I want to ask if I can avoid that 600x600 limitation somehow.
It is really sad right now, because the backgrounds/fan arts looks so great in full 1920x1080, and then for no reason at all the thumbnails look so horribly out of place with that low quality..


Thank you really much.
I am nearly finished with everything, it is just that thumbnail problem and a few other small things. Other than that I am really happy with Mezzmo!


EDIT: Now not even the 600x600 show up anymore and I don't know why.. It is now clearly lower than 600x600x.. All that I want is to have my 480x720 Kodi Thumbnails

Peter typically comes on later due to the timezone difference. You can see the device profile setting in the Media Devices option in the main GUI window.

Generic Device NTSC.

Also, I just posted an edit to my previous post, while you replied.

Ok, that Device Profile needs to be changed to Kodi since you are using Kodi. Otherwise you may end up transcoding things and such. I looked at the device profile file for NTSC generic and Kodi. If I am reading them right the thumbnail size for generic is 160x160 and 320x320 for Kodi. So changing to Kodi should help. If so then we should be able to modify the device profile file and get it higher. Again Peter can help here to confirm.

So I dug through some older forum threads to confirm my thoughts. To go with larger thumbnails higher than 320x320 with Kodi you'll need to edit the device profile (kodi.prf file located in C:\ProgramData\Conceiva\Mezzmo\DeviceProfiles) . Make a backup copy of it. Then open with Notepad. Near the bottom you will find:

<avcontainer id="jpeg" name="jpeg_tn" mimetype="image/jpeg" encode="1" baseline="1" dlnaprofile="JPEG_TN" preferredthumbnail="1" supportschunked="0">
<image>
<format id="jpeg" mimetype="image/jpeg" encode="1" codec="98" quality="2">
<maxdimensions width="320" height="320" />
<maxbits>24</maxbits>
</format>
</image>
</avcontainer>

Change the maxdimensions and save. Then stop / restart the Mezzmo server from the GUI .

Good ok, so the Device Profile is now Kodi. I guess that is anyway better to do that.
But it didn't allow me to change to higher than 600x600.
And then, actually it is still for some reason stuck on 213x320, no matter what I scan.

Before that it worked. I really don't know what I am doing different than before.
I had 600x600 working, and suddenly after I deleted my experimental library again, it did not scan 600x600 anymore.

I will try to search that Profile File, because earlier today I found a thread somewhere talking about that.

You will likely need to run maintenance (Maintain Playlist) and regenerate your thumbnails. I'd start with a single folder selecting only Update view preview Thumbnail , Video files and Folders / Playlists.

I did it and it just downloaded the thumbnail once again in the same size 213x320..
What actually happened? I feel like I need to do a reinstall of the whole Server.

It does not even matter if I download the thumbnails, or if I use the thumbnails from my Kodi backup, because it just scales them down for some reason.
I even tested it with paint, I drew some lines on one of my Kodi thumbnails, and then imported it. And yes, it got scaled down to again 213x320.. always that same number.
Not one of my Thumbnail Sizes (small, medium, large) have that size. So where does that number come from?


EDIT: Good news! After changing the Poster image sizes in "Streaming" at Options, it now at least in my appdata folder saves the thumbnails as the full size 480x720 files!!!
BUT.. on my TV Box it still is blurry and not full size, instead still some kind of down scaled version. I don't understand where that is coming from.

Probably the device profile for Kodi bringing them down to 360x360. Did you make the edit device profile change recommended above ? Peter will be around later and will be able to sort it out, if the profile change doesn't fix it.

In Options under streaming is the size for all devices, Mezzmo will save the original posters in this size. For each device there is a poster size defined in the profile and Mezzmo will resize the posters to fit within this size. The JPEG_TN size in the Kodi profile is 320x320 so the posters will be resized to fit within this. To make the posters larger you will need to increase this size in the profile then save it and restart your Mezzmo Media Server to reload the profile. Then you will need to go to the Kodi device in Media Devices and on the Transcoding tab click the button to delete transcoded files so that the old small posters are re-transcoded to the larger size from the profile.
