Nextcloud - Files_PhotoSpheres

Nextcloud app for viewing Google PhotoSphere 360° images (panorama-images). This app is based on the photo-sphere-viewer.js library. For 360° videos the library marzipano is used.

This version is tested for Nextcloud 24.

Features

• Interactive viewer to view PhotoSphere images in your Nextcloud instance
• When clicking on an image it automaticlly detects the presence of XMP-data tags (which are used in photospheres).
• Compatible with the "normal" user-view, single-file share and directory share.
• Seamless integration with other file-viewer apps.
• Supports viewing of 360° videos in "normal" user-view via context menu.

Setup

Install through the app store

The recommended way to install this app, is through the Nextcloud app store.

Open your Nextcloud instance -> Settings -> Apps -> Multimedia -> Photo Sphere Viewer -> Download and Enable.

Install manually

You can manually install this app, by cloning the repository into your nextcloud installation:

cd <your-nextcloud-installation>/apps/
git clone https://github.com/nextcloud/files_photospheres.git
chown www-data:www-data -R ./files_photospheres

Usage

After installing the app you can view your PhotoSphere 360° images by clicking on the file in the Nextcloud file browser. Note that opening PhotoSpheres from the gallery is currently not supported.

Caveats

• It is not possible to open the photosphere viewer from the Gallery. You must use the file browser.
• WebGL-support must be activated in your browser.
• 360° videos can not be shown in shared views. It is only possible to open them by context menu therefore the files_rightclick app has to be installed (see https://github.com/nextcloud/files_rightclick).

Report an issue

I rely on all kind of feedback so feel free to open an issue if you encounter any problems with this app but please pay attention to the following points:

• If there is a problem with some images which aren't opened in this app but rather in the regular image viewer, please provide them via downloadlink if possible. Otherwise debugging and error-checking becomes quite hard. Please also check if the image you provide has correct XMP-metadata for being detected as photosphere image (like specified here). The image is only detected as photosphere if the XMP-metadata contains the following data:

  • GPano:UsePanoramaViewer is set explicitly to true or
  • GPano:ProjectionType is set to equirectangular or
  • GImage:Mime is set to image/jpeg (this is currently the only reliable way to detect Google VR180 images, see #1)

  You can check these metadata information either with tools like exiftool or manually by opening the image with your favorite texteditor and scrolling throw the first few bytes.

• In the frontend this app is only an integration of different external components like photo-sphere-viewer.js and marzipano. Therefore problems regarding these libraries cannot be fixed in this app.

Thanks for your support 😃
