User Story
As the owner of a large collection of video files I need a digital preservation system that can characterise very large audio/video files to enable me (or a watch system) to evaluate the collection for preservation risks and ongoing risk management.
User Requirements/Components
- We need to be able to characterise very large video (8GB+) files
- This includes identifying container formats and contained streams
- Features extracted need to be decided - we need to consider what is useful here to extract and include here as requirements. See:
- Needs to perform characterisation quickly and efficiently
- Would be good to be able to validate video format compliance with specification
Experiments
Create experiments as child pages and they should appear automatically here
Execute ffprobe across content (NBR)
Data: Available. Sharable.
Workflow: No.
Issues: Tool too fast to give scale problems.
Developer Notes
The original scenario expressed some concern that existing characterisation tools (JHOVE for instance) do not seem to work well on large files.
This story provides the opportunity to compare tools over time, such as the Tika/DROID/etc. as performed by PC.CC. (See also Incubator)
