Video geotagging format (WebVMT)

[tidoust]

The Web Video Map Tracks Format is a proposal for a text format derived from WebVTT that allows to associate geotagging information with a video, for instance to synchronize video playback with movement on a map.

The proposal was raised by Rob Smith (@rjksmith) and is being discussed in the Spatial Data on the Web Interest Group. See:

• Minutes of video geotagging format discussions during SDW IG F2F in Amersfoort, 20 February 2018
• Presentation slides in PDF

@rjksmith is working on an explainer document.

WebVMT Status Update

1. Progress Made

   1. Attended the Drone Futures conference on 13 June at Tech UK in London to engage with the drones community. Received good feedback on the WebVMT concept from manufacturers and users, with interest shown in the forthcoming website (item 1.ii), and identified some interesting new use cases.

   2. Made good headway with creating a public-facing website for WebVMT, to help engage communities, promote the format and encourage uptake. Planned pages include a features overview, several technical demonstrations, including YouTube integration, and a development blog.

   3. Created a Content Management System (CMS) plugin for easy integration of the WebVMT playback engine with the website (item 1.ii).

   4. Fixed a bug in the YouTube tech demo, resulting from anomalous API behaviour during pause.

   5. Identified a number of strategic and principal OGC members to approach regarding OGC Test Bed activities, as suggested at SDW IG meeting on 6 June in Fort Collins.

2. Next Steps

   1. Complete the WebVMT website implementation, and go live.

   2. Use the website as a focal point for community engagement activities to publicise the format and to inform key players, particularly those who can help move it forward through the standardisation process, early adopters and those interested in suitable Test Bed work.

   3. Develop the WebVMT specification to address outstanding issues and community feedback, including new drone use cases.

3. Help Requested

   1. Identify suitable points of contact in OGC member organisations - particularly strategic and principal members. Candidates include ESA, NASA, Ordnance Survey, Airbus, Esri, Geoscience Australia and Google, though other suggestions are also welcome.

   2. Find appropriate representation in the OGC Disasters CDS, as described in issue #1048.

[6a6d74]

@rjksmith - looks like you're making good progress. Did you get any of the "help requested"?
Additionally, I note that

• @MichaelGordon was going to provide an introduction to DSTL; did this happen?
• @lvdbrink suggested arranging a slot in the OGC Defence and Intelligence WG; did you consider this?
• there is a GitHub repo for OGC Testbed ideas (new ideas seem to be added as Issues) - did you look at this? (I don't see WebVMT on the list)

[rjksmith]

@6a6d74 Thanks for following up on this. No, I'm awaiting responses to my help requests.

• I've heard no news from @MichaelGordon.
• @lvdbrink Are you proposing a general introduction to WebVMT, or do you think there's a particular use case/aspect of interest to D&I DWG?
• I've not yet raised any WebVMT issues on the OGC Testbed ideas repo, as I thought it better to discuss with suitable OGC contacts first, to get an understanding of their aims and interests, for the best chance of success.

[rjksmith]

The community engagement website, proposed at the Fort Collins meeting in June, is now live at webvmt.org, with a features overview, blog and tech demos including:

• an introduction to WebVMT, filmed on location in Farnborough - the birthplace of British aviation;
• London to Brighton by train in 4 minutes, demonstrating YouTube integration.

TPAC Breakout Session: Video Metadata Cue Support Including Geolocation

A breakout session was proposed at TPAC Lyon, 24 October 2018, to investigate the use of HTML timed text track metadata for geolocation support, with WebVMT as a particular use case. Requirements for the emerging markets are identified in the Editor's Draft use cases, also listed on the WebVMT.org website.

The key issue is whether existing metadata cues can provide support for general metadata, with a suitable identifier to discriminate different types, or whether a special type is required for geolocation support.

A collaborative approach was proposed between Spatial Data on the Web and the Media & Entertainment IGs within a Web Incubator Community Group activity to investigate this issue and prototype a solution.
