Raspberry Pi & XBMC is AWESOME with Mezzmo.... except the poster art

[smitbret]

So, I have been wanting to do something with the XBMC client side of things for Mezzmo and had been thinking about building an HTPC, but just hate the idea of spending a couple hundred dollars. So I dropped $35 on a Raspberry Pi, installed OpenELEC on it and it actually works more smoothly than my WDTV Live.

My question is, how do I make the thumbnails not look so awful and low resolution? The thumbnails are stored as 40-70k .jpg files that are 400x600. Should be plenty for a decent thumbnail on screen, but they look more like 100x150. I have. the thumbnail settings at 400x600/Large and I have rebuilt the artwork in the library

Regarding thumbnails, depending on the device profile you have selected, artwork thumbnails may be 160x160 pixels (the DLNA standard). To change them to a larger size for a particular device profile, here's what you need to do:

1. Stop your Mezzmo media server and exit Mezzmo using File/Exit.
2. Assuming you are using the 'XBMC' device profile (go to Media Devices dialog to check this), you need to edit the 'XBMC.prf' device profile with a text editor such as Notepad. See this thread for the location of device profiles: http://forum.conceiva.com/showthread.php/467-FAQ-Where-are-device-profiles-located. Before editing the file, change the file properties from being read-only. In your text editor, look for:


<avcontainer id="jpeg" name="jpeg_tn" mimetype="image/jpeg" encode="1" baseline="1" dlnaprofile="JPEG_TN" preferredthumbnail="1">
<image>
<format id="jpeg" mimetype="image/jpeg" encode="1" codec="98" quality="2">
<maxdimensions width="160" height="160" />
<maxbits>24</maxbits>
</format>
</image>
</avcontainer>

and change it to:


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

3. Save the XBMC.prf file
4. Start Mezzmo and go to the Media Devices dialog. Edit your device and on the Device Settings dialog, go to the Transcoding tab and delete all transcoded files.
5. Start your Mezzmo server and you should see larger thumbnails now.

Excellent, worked nicely, although it slowed the Raspberry Pi's ability to shuffle through the library when I had it set to 600x400. I set it to 300x200 and it works again quite nicely for the media thumbnails.

However, the top level folders (video, music, photos & the folders above the actual media) all still seem to be in the lower resolution.

Glad that (mostly) worked.

Try deleting all your transcoded files using the Transcoding Settings dialog and see if that helps. That will remove all transcoded files from Mezzmo's cache and should then force Mezzmo to use the 320x320 pixel artwork.
