Emby Server Unable to Parse Compressed TIF Files

[dark_aegis 3]

I've got a bunch of scanned images in compressed TIF format and it looks like Emby is having trouble seeing them - only showing a broken image where they should be in the browser.}

The files were scanned uncompressed then bulk lossless compressed via a script in photoshop. I believe I used ZIP compression. Uncompressed TIF seem to show up fine.

Here's a sample of what I'm seeing in my log when I try to get them running - this is on the newest stable version of Emby, but it's been an issue since I started using it - the most telling bit seems to be the repeated "AdobeDeflate compression support is not configured":

I doubt it'll help, but this is what I see in the interface.

Gotcha. My bad on extracting the part I thought was pertinent - actually against the guidelines, whoops. Usually I'm better at reading directions than that. Here's the full entry.

I saw that there were other logs, but they were created before I went through and tried to generate thumbnails/view the problem files. The issues seem to start around line 379.

My album is a mix of jpeg, compressed tif, and uncompressed TIF, so a lot of the images were able to successfully generate - you should see a few points in the log, though, where dozens of photos failed (I was able to get the pages of broken images a few times).

Let me know if you need anything else.

OK so the bundled libtiff needs to be compiled with support for certain features. Hopefully it is easy enough to add libraries but it usually doesn't end up being that simple. We'll look into it. Thanks.
