Coded Concepts with media content support in metadata

Overview

Avni supports adding media content (videos and images) to coded concepts through metadata. This feature allows concepts to reference media files that are synced to field devices and can be displayed within forms.

Feature Description

Media content support to concept metadata enables:

Adding video and image references via "App Designer"
Automatic syncing of media files to field devices
Inline display of media content within forms
Offline access of the synced media files

Use Cases

Counselling and Guidance

Display instructional videos showing correct procedures or techniques
Show visual examples to help beneficiaries understand health concepts
Provide image references for medication identification or usage instructions

Training and Reference

Include training videos for field workers to reference during data collection
Display procedural demonstrations to standardize how tasks are performed
Provide visual guides for complex decision-making processes

Quality Assurance

Ensure consistent information delivery across all field workers
Reduce errors by providing visual reference materials at point of data entry

Configuration

Adding Media to Concepts

Navigate to Concepts tab, in Avni admin interface, "App Designer" section
Create a new concept or edit an existing one
In the concept editor, locate the media upload sections:
- Image (max 150 KB): Upload JPG or PNG image files
- Video (max 10 MB): Upload MP4 video files
Upload the desired media file(s)
Save the concept

Media files are automatically synced to field devices during the regular sync process and become available offline.

Using Media-Enabled Concepts in Forms

Media added to a concept can be used in forms as follows:

Answer options: Display images or videos alongside answer choices to guide user selection
Question explanations: Show supplementary media to clarify what information is being collected

Supported Media Types

Videos: MP4 format - max 10 MB
Images: JPG, PNG formats - max 150 KB

Technical Considerations

Media playback depends on device capabilities
Test on target devices before deployment
Storage constraints may limit media file quantities on field devices
Network connectivity required for initial sync
Media files are cached locally after sync for offline access

Mobile application capability

Sync and Storage

Media files are downloaded during standard Avni sync process
Files are cached locally for offline access
Storage management follows Avni's existing file handling patterns

Field Worker Experience

When a form contains media-enabled concepts, field workers see:

Media Icons: Small media icons (video or image) appear next to the question or answer options
Accessing Media: Tap the media icon to view the content
Video Playback: Videos open in the device's default video player or play inline
Image Display: Images open in the device's image viewer or display inline
Offline Access: All synced media is available even without internet connection
Guided Answers: Visual media helps field workers understand and select the correct answer options
