The media that seems to have the least support from Mezzmo are photos. Not only are EXIF tags (EXIF is the photo industry standing tagging for digital photos -- all digital cameras, smartphones, video cameras and so on write EXIF data into their image files) largely not read, but the active and other playlist tools refer only to music tags such as "Album/Artist" etc.

I'm trying to display a 10,000 jpeg photo collection and the only useful information that it can be displayed on is the year tag. Or perhaps I'm missing something?

The current version of Mezzmo (v3.0.2.0) does read some EXIF & IPTC tags (originaldate/datecreated/datetime, artist/author, description/caption/comment/model) but I agree that there are many more that Mezzmo could read and make available for organizing your photos.

What EXIF tags are you interested in?

Paul,

My main interest is being able to sort by the freeform "tags" that I have inserted in my photo files mainly by Windows Photo Gallery. WPG allows editing of a number of tags (including the key EXIF ones), and it also allows tagging to, for example, an individual or individuals shown in a photo. I suspect in reading about this, that it is using the Adobe XMP standard, since there doesn't seem to be any practical limit on the number of these "tags" that can be added to an image file.

Recent versions of WPG allow tagging to people's names in addition to the general descriptive tags. However, these additional tags don't seem to be read by other DLNA servers (twonky mainly), or perhaps interpreted by DLNA renderers (mainly Panasonic TVs and WD Live media players).

The WPG software is of course widely used since it was free and included in Windows Vista, and freely downloadable since then for any version of Windows (variously called Windows Live Photo Gallery, Windows Photo Gallery).

HP also ship a photo gallery editor on their workstations, and it appears to also be able to read and tag in a compatible way with Windows Photo Gallery.

The straightforward EXIF tags showing camera used, for example, are also useful for sorting a display by source of photos. (For example, a slideshow of slides from one of my kids Nintendo DSis).

And finally, the EXIF tags that show photo rotation need to be read and served since you get upside down photos on any slide show if you don't observe the correction you've made by rotating the image on WPG.

Be interested in your thoughts about these. Happy to provide some samples if that's useful.


Regards,
tony

Thanks, Tony. We'll discuss this here and consider upgrading our photo metadata support for an upcoming version. Please do email us a few sample photos to support [at] conceiva [dot] com. They will help us test any implementation we decide upon.

Been trying to work out how to show photo tags in Mezzmo, but I can see from the posts here that it's pretty limited in this respect.

I've got a fairly large photo collection. Maybe 30,000 images. But unless I can sort them by the standard tags, mezzmo just doesn't work for me at all. Some of the tags appear to display in the comments field, but you can seem to include them in any index.

I've been trying out your server on a friends machine, and it looks pretty impressive, but I really can't buy a copy until you can fix this. Any idea when this is going to happen?

We're in final testing for a new version at the moment, but once that has been releaseed next week, then we may be able to address some of the photo tagging issues. What "standard tags" from photos do you want to see & index on in Mezzmo?

thanks for coming back to me. The photographer and the caption would be useful. The specific tag I really need is the one where I can label a photo to one or many names. These are often the names of friends or someone in my family where they appear in a photo. Indexed on these I can see all photos of my wife, for example, by the year in which the photo was taken

The software I use has specific names for things such as photographer, camera, date taken, apeture, shutter speed, film speed (most of which are automatically inserted by the digital camera) but the one that can include a name or a place is just called "tag".

I use Adobe Photoshop to edit tags, but in a hurry I sometimes use the windows stuff.

Understand. We'll look at these tags for an upcoming version.

I've just joined the forum and was hoping to find out how to sort my photos by the Descriptive Tags that Vista Photo Gallery inserts. I think that is what is meant by "tags" in Willy9009s comment above? If so then, yes please, let's have this feature.

Thanks for adding your vote, Erica. We'll add this into a future version of Mezzmo.

Definately needs to respect the Exif tag for rotating photos as this is really annoying when your looking at photos and having to turn your head around all the time.
Not sure if videos (e.g. mp4 files from iPhone) have Exif but all the photos and videos that I take on my iPhone are displayed with incorrect rotation. Would be great to get that fixed.

Hi ifflanb,

Mezzmo does read the EXIF tags for rotation and will rotate the photos before streaming them - but only if the device you are streaming to does not rotate photos itself. Many devices read the EXIF tags and rotate the photo themselves, so there is no need for Mezzmo to do unnecessary transcoding (rotating) of the photo. Please email us at support [at] conceiva [dot] com and tell us:


What device are you streaming to?
What device profile do you have assigned to this device in the Media Devices dialog in Mezzmo?

After we get this information, we'll provide an updated device profile that does the auto rotation of photos for you.

Hi,

My 2 cents ... I would love to be able to extract photos based on their tags. But then, once I have a filtered list of all the photos tagged, say, "birthday", I'd love to be able to have them grouped/presented by year, and then month. A mix of smart and active playlist, really.
Beyond the use of the EXIF "tag" field, do you plan to merge active and smart playlists one day?
Thanks

Ben

Hi Ben,

Yes, we do plan to merge active and smart playlists. We agree it's a good idea.
