Version 1.01 not working

Could this be the same problem described in #7?

[TheNetStriker]

I've also updated to 1.0.1 and disabled the viewer app, but the photo sphere viewer is still not working. I also found no infos in the log regarding the problem. Any ideas what could cause the problem?

[R0Wi]

Did you enable the "Gallery-App"? See #15

[TheNetStriker]

Yes the Gallery app is enabled. If I click on a PANO_ image the image is opened in the Gallery app instead of the Panorama app.

[R0Wi]

Do you see anything in the devtools console? Are the photosphere scrips loaded properly (see https://github.com/nextcloud/files_photospheres/issues/5#issuecomment-502642566)?

By the way: with version 1.0.1 the images dont't need the PANO_-prefix anymore. There's a serverside check if the image is a photosphere. Could you check if the request is visible in the network tab (https://github.com/nextcloud/files_photospheres/issues/5#issuecomment-502483373)?

[TheNetStriker]

@R0Wi I've just tested this. Both .js files are loaded in the devconsole, but I cannot see the request for xmp data. I've tried with the gallery app only, with the viewer app only and with both apps enabled. What could be the problem?

Edit: After I've cleared the cache in my browser I can see the xmp request, but it returns {"data":null,"success":true}. Are there any libraries that are required to get the xmp data?

[R0Wi]

Ok seems like the xmp-data-check works just fine. This means that your image has no xmp-data stored in it. Is it possible that you post your image here, so that i can analyze it?

[TheNetStriker]

I just found out that the problem only occurs on photos from my older Samsung Gear 360 camera. The photos from the Insta360 camera are working. The Gear 360 also contains XMP data, but I guess they provide different infos than the Insta360. I've uploaded an example photo from my Gear 360 camera to my dropbox: https://www.dropbox.com/s/yv50li7lwq17tow/360_0412_Stitch_YHC.JPG?dl=0

[R0Wi]

Thanks for providing the image. Seems like the xmp-data-block is present but there is information missing, which is obligatory for the viewer. Actually the viewer expects the following GPano-Data inside the xmp-block:

FullPanoWidthPixels FullPanoHeightPixels CroppedAreaImageWidthPixels CroppedAreaImageHeightPixels CroppedAreaLeftPixels CroppedAreaTopPixels

If none of these are set, the viewer will not open. I actually didn't test if the viewer can open it but i know, that it would request the image twice if we don't provide xmp-data while initialization.

I'll test this and may do some adaption in code these days. Will keep you up to date :-)

[Sanookmakmak]

I have set those XMP-parameters, as well as

• ProjectionType = equirectangular
• UsePanoramaViewer = True

I have installed Nextcloud 16.01, Gallery-App 18.3.0 and PhotoSphereViewer 1.0.2. The "Viewer" App 1.0 is disabled and deleted.

But the PhotoSphereViewer does not display the panorama as photosphere. It is not renamed to PANO_xyz.jpg anymore.

Here is an example panorama, 360x180°, which is displayed as photosphere in Google Photos:

[Sanookmakmak]

BTW: PhotoSphereViewer 1.01 stops sharing folders:

https://help.nextcloud.com/t/how-should-the-photosphereviewer-work/54690/3

[R0Wi]

Thanks for the image, i'll test this soon.

The sharing issue is fixed in version 1.0.2 see #14

[Sanookmakmak]

The Gear 360 also contains XMP data, but I guess they provide different infos than the Insta360

Here is a workshop how to add XMP metadata to make a photo to a photosphere @TheNetStriker:

[R0Wi]

@Sanookmakmak you're right, the viewer-component itself is able to display your image. I'll make some adaption to make the app compatible with it.

[WNYmathGuy]

I'm new here. I just tried to use this app today. I didn't know it was available till a few days ago. I'm in Nextcloud 16.0.1 & Photo Sphere Viewer 1.0.2 and I get no reaction when selecting [view in PhotoSphereViewer] for panorama's, semi-spheres or 360 spheres taken with an Android phone. I tried looking at the logs in realtime all levels in an admin window in one browser while trying to view photo spheres as a user in another browser window and I saw nothing looking like an error for this app.

Anything I can do to toss back useful diagnostics to help this app along?

[R0Wi]

Hi @WNYmathGuy, thanks for your feedback. I'm not quite sure what you mean if you say "when selecting [view in PhotoSphereViewer]". Do you mean the context-menu? What happens if you just left-click on the image?

[WNYmathGuy]

@R0Wi Here are some screenshots and a sample photosphere file.

No right click menu in the normal viewer.

[R0Wi]

Thanks for the material. I didn't manage to get the little contextmenu where it says "Open in PhotosphereViewer" in my NC instance. How did you get that menu?

And what happens if you directly click on an image?

[WNYmathGuy]

Thanks for the material. I didn't manage to get the little contextmenu where it says "Open in PhotosphereViewer" in my NC instance. How did you get that menu?

And what happens if you directly click on an image?

I have no idea why the "..." tool has that "Open in PhotosphereViewer" in there. I think at one time that tool menu was an option for nextcloud via an app, but they built it into the core. That's based on my old person's memory though.

Clicking directly on an image in grid view opens it in the standard viewer as a rectangle raster. Theirs no context menu while it's in the standard viewer.

Does my photosphere file render for you correctly? It was made with either a Nexus 5 or a Nexus 6p a while ago and stored on Google Drive till I found Nextcloud.

[R0Wi]

I loaded it into my NC test instance and it's opend correctly. But i'm using the new version 1.0.3, which was launched just a few minutes ago. Would you try it with this version and give me some feedback?

[WNYmathGuy]

Oh, damn! That's good! I like the tools at the bottom camouflaged with transparency. Great speed with the photo movement and load time. That option in the "..." tool is gone. To open the photo was either a single click in the grid view or a select in the details view, then a single click on the thumbnail in the Info panel. I love that I can twirl it forever. I assumed that semispheres taken with the same device would open in your viewer, but they don't. I'm not knowledgable with meta-data in pics so I won't guess why that happens. Here's an example file:

Might be worth a screen message in the center that vanishes after 1.5 seconds "Press Esc to close".

[R0Wi]

Nice to hear, so if i get you right things working now on normal photospheres? :-D

I'll investigate in the image you mentioned and give you a feedback, if this could be shown in the viewer, too.

To exit the app you actually have to press the ESC-key, we're planning to have a little cross at the top right edge in the future.

[WNYmathGuy]

@R0Wi I just tried viewing images taken with a Vivitar DVR978HD camera. It's basically two 2K fisheye cameras back to back with hardware stitching. They don't render in the viewer, they just open like an ordinary rectangular photo. Here's one:

Is your app just supposed to open a full photosphere taken with a non-VR camera? Or is the Vivitar not building the file correctly?

[WNYmathGuy]

This could be useless information @R0Wi but on a Ubuntu 18.04 desktop this git project let me view those files properly: https://github.com/JeremyHeleine/Photo-Sphere-Viewer

Saw it demo'ed here https://www.youtube.com/watch?v=jRMLL311Cho

[Sanookmakmak]

Or is the Vivitar not building the file correctly?

XMP metadata are missing

• https://developers.google.com/streetview/spherical-metadata
• https://www.facebook.com/notes/eric-cheng/editing-360-photos-injecting-metadata/10156930564975277

[R0Wi]

Could be, that the xmp-data (at least a "GPano"-information) is missing.

Well the whole magic here is to decide, whether the image should be opend in PhotosphereViewer or in regular image viewer. Both are jpeg-files and therefore have the same mimetype. So we have to do a serverside check of the file, after clicking on it. In version 1.0.3 this check at least expects a GPano tag in the metadata.

But of course i can adapt the check if it makes sense to open those fisheye-pictures in the PhotosphereViewer. But then i need a clear property, which tells me that the file is a fisheye. So i'll have a look at your images and see, if i can find something :-)

[R0Wi]

@WNYmathGuy i was able to get it to work. If you'd like to test it you can clone the branch: https://github.com/nextcloud/files_photospheres/tree/feature-improved-xmp into your "files_photospheres"-appfolder

I'm a "ya basic" when it comes to git. Do I just navigate to the folder as the Nextcloud admin and run the git pull command?

[R0Wi]

I'd suggest you clean the nextcloud/apps/files_photospheres folder. Then navigate into that folder and run git clone https://github.com/nextcloud/files_photospheres.git . Then do a git checkout feature-improved-xmp

Let me know your results :-)

[WNYmathGuy]

One minor thing went wrong. I emptied the nextcloud/apps/files_photospheres folder. I was in the nextcloud/apps/files_photospheres folder with a shell prompt when executing git clone https://github.com/nextcloud/files_photospheres.git and what I should have done was deleted the files_photospheres folder then ran the command from the nextcloud/apps folder. What I did was move the files from nextcloud/apps/files_photospheres/files_photospheres folder into the nextcloud/apps/files_photospheres folder then deleted the nextcloud/apps/files_photospheres/files_photospheres folder.

The result was no photo was displayed, but there was a reaction to clicking the photo. This is now the same reaction to clicking on ones that worked before and any photo that was taken with the Vivitar. See image below.

To go from white-screen back to the file browser, I hit escape.

I'm getting prompted to upgrade to NC 16.0.2, should I do that first?

[R0Wi]

Well the images you provided worked in my NC instance. I never had this strange behaviour that just a blank page was shown :-)

Are there any errors on your browsers devtools console?

[WNYmathGuy]

@R0Wi you sir are talking to a non-web developer. I'm guessing my way through that request though. Here is a screenshot I think may be useful?

This morning I thought a reboot might fix it on my Ubuntu 18.04 workstation because yesterday I clicked to stop a script slowing the page load in Firefox while I was simultaneously running Thunderbird and Google Chrome with dozens of tabs in each browser. The reboot delivered the screenshot above.

Moments ago I tried it on my wife's Windblows 10 machine in Google Chrome and it worked as advertised. So I opened my Chrome browser on her machine and it also worked as advertised. I opened my Ubuntu 18.04 (old Toshiba) laptop and it worked fine there too!

Something is installed on my big desktop that is the fly in the ointment? Firefox and Chrome on the Ubuntu desktop no, everything else yes. Or could it be the MSI card with 3 different monitors plugged into it have some quirk? Or could it be that https://github.com/JeremyHeleine/Photo-Sphere-Viewer that I put on this machine only that's breaking it?

[WNYmathGuy]

I upgraded my Nextcloud server and now for some reason the photos load as advertised.

[R0Wi]

@WNYmathGuy it's quite hard to guess, what's gone wrong for you but i think if it's working now it should be fine. To which NC Version did you upgrade?

I'll push the changes into the appstore these days :-)

[crossbuilder]

Here are two files taken with the same cam (DJI).

This one works:
http://z99a.camedel.de/s/HwxQPXfRyyLnc9k This one does not.
http://z99a.camedel.de/s/sst9jTJQgPLZNFE

I can't see any difference in the tags. Nextcloud 16.0.3 PhotoSphere 1.0.3

Note: Both links will expire on saturday, so please download if you want to keep the images for testing.

[R0Wi]

@crossbuilder i moved this to #23. Thanks for your feedback.

[WNYmathGuy]

@R0Wi I upgraded from 16.0.1 to 16.0.3 but I don't think it was the problem because it worked on other devices using the same software prior to the upgrade. Maybe it was a browser cache issue?
