.dv Files Not Recognized #997
Comments
There's no identification signature for x-fmt/152 yet but they should at least be coming up with an extension-match. David |
Hello @Dclipsham , I'm working with @Lawrence58. |
You could look at the external Java API that was added in v6.6.0, although bear in mind that it's early days for this and this might change in future. The unit tests for this might give an indication of how it would work, but this should provide extension-only matching (and container signature matching) as seen in the unit tests https://github.com/digital-preservation/droid/blob/master/droid-api/src/test/java/uk/gov/nationalarchives/droid/internal/api/DroidAPITest.java |
As mentioned by @steve-daly |
Is it on your roadmap to have signature matching for DV files? And if so when do you think it could be released? Thanks. |
Hi @jendib you could engage with the Pronom file format team here https://www.nationalarchives.gov.uk/pronom/submitinfo.htm ideally providing information or a signature for the format (e.g. from this kind of work https://cdn.nationalarchives.gov.uk/documents/information-management/pronom-file-signature-research.pdf). I suspect these are dv-dif files, i.e. the elemental form of DV video which might often be wrapped in AVI, MOV, MXF etc. You'd ideally want to find a spec for this format to see what byte sequences might uniquely identify them, although I suspect this might vary on various flavours of the format (e.g. frame rate, bitrate). |
I ran .dv video files through DROID but the output was empty. It doesn't even include .dv as the file extension. When I search the PRONOM registry using the .dv extension there is an entry with MIME: video/dv and PUID: x-fmt/152. I assumed that meant DROID had some support for .dv files. Is that not the case or is something wrong?
Thank you, Kevin Irelan
