For DSpace-CRIS 9.2, the "basic media viewer" works in the default XMLUI/JSPUI, but CRIS custom layout uses Angular UI which doesn’t include it out-of-the-box. You’re right - 4Science docs point to their paid “Advanced Media Viewer” addon.
But you can enable the basic media viewer without buying the addon. Here’s how: Option 1: Backport the default Media Viewer component to Angular UI This is the “basic” viewer DSpace uses - just a simple HTML5 `<video>` / `<audio>` / PDF `<iframe>` player. Steps: 1. Check if bitstream is downloadable In `config/cris/cris.cfg` or `local.cfg`: webui.bitstream.inline = true If `false`, the basic viewer won’t trigger because Angular UI won’t render inline. 2. Modify Angular UI theme to render bitstreams CRIS custom layout hides the `item-bitstreams` component by default. Edit your custom layout: `src/app/item-page/simple/item-types/cris-layout/cris-layout-item/cris-layout-item.component.html` Add the basic viewer component where you want media to show: <ds-media-viewer [bitstream]="bitstream"></ds-media-viewer> The `<ds-media-viewer>` component already exists in DSpace 7+ Angular UI for default items. CRIS layouts just don’t include it. 3. Update MIME type mapping In `dspace.cfg`: mimetype.supported = video/mp4, audio/mpeg, application/pdf, image/jpeg, image/png Basic viewer only works for browser-native formats. No http://PDF.js, no IIIF - just native playback. 4. Rebuild Angular UI `yarn install && yarn build:prod` then restart Tomcat. Option 2: Quick hack - Use bitstream link + browser player If you don’t want to touch Angular code: 1. Go to `src/app/item-page/field-components/bitstreams/bitstreams.component.html` in CRIS layout 2. For `bitstream.mimeType` starting with `video/` or `audio/`, render: <video controls ngIf="bitstream.mimeType.startsWith('video/')" [src]="bitstreamLink"></video> <audio controls ngIf="bitstream.mimeType.startsWith('audio/')" [src]="bitstreamLink"></audio> This gives you the exact same “basic” viewer as default UI, no addon needed.
