Scan date: 2026-03-30

Summary

No authentication or Cloudflare blocks encountered on any platform. NotUBiz API is fully public. GemeenteOplossingen uses time-limited Wowza tokens for video streams. Everything else is publicly accessible.

NotUBiz (317 municipalities)

Architecture

Angular SPA backed by api.notubiz.nl REST API. Video playback via embedded JWPlayer. Video files stored on Wowza streaming server, accessible as direct MP4 downloads.

API Endpoints for Video

Video Availability per Municipality

Key Findings

• The live boolean on events correlates strongly with media availability: events with live=true almost always have MP4 recordings
• Amsterdam has the highest coverage (96%)
• Den Haag has zero stored media despite having JWPlayer active, may host video externally
• MP4 naming pattern: DD.MM.YY City MeetingType.mp4
• Wowza server: rtmp://wowza1.notubiz.nl/nbvod/_definst_
• SRT subtitles are available on some recordings, huge win for transcription validation

iBabs (153 municipalities)

Architecture

Server-rendered ASP.NET MVC application. Video integration via data-video-type attributes on HTML div elements, with external player at player.ibabs.eu.

Video Integration Types

iBabs doesn't have one video system. Each municipality can use a different provider:

Availability per Municipality

Key Findings

• Video data embedded in HTML: data-video-type, data-video-id, data-video-url, data-video-base-url on <div class="cwc"> elements
• player.ibabs.eu is a SPA shell (472 bytes), loads video dynamically by GUID
• Three different video providers across tested municipalities
• No single extraction method will work for all iBabs municipalities
• Enschede has the best video integration with availability icons on meeting lists

GemeenteOplossingen (34 municipalities)

Architecture

Custom CMS with server-rendered pages. Video infrastructure uses its own Wowza streaming instance (separate from NotUBiz). Players: VideoJS + FlowPlayer. Has dedicated JavaScript modules: StreamController.js, ArchivePlayer.js, LivePlayer.js.

Video Infrastructure

Best video integration of all platforms. Built-in support for:

• Live streaming with DVR capability
• Archive playback of past meetings
• Per-agenda-item video fragments (embed with start/end times)
• HLS delivery with token authentication

Availability per Municipality

Video URL Pattern

https://{wowza-server}/vod/_definst_/{city}_1/{date}-{meetingname}_1.mp4/playlist.m3u8
  ?wowzatokenendtime={timestamp}
  &wowzatokenhash={hash}
  &wowzaplaystart={ms}
  &wowzaplayduration={ms}

Key Findings

• Wowza tokens are time-limited but publicly generated (no auth needed to get a token)
• Fragment-level access: wowzaplaystart and wowzaplayduration allow extracting specific agenda item video
• Live streams support DVR (rewind during live broadcast)
• "Komende uitzendingen" widget shows scheduled upcoming broadcasts
• 2 out of 5 tested municipalities had DNS issues, suggesting some may have migrated

ConnectedViews (1 municipality: Utrecht)

Architecture

ASP.NET web application hosted on Azure. Dedicated video platform (not a council info system with video bolted on). Uses VOS360 as CDN/streaming provider.

Endpoints

Key Findings

• Both live and VOD supported with the same player infrastructure
• Direct MP4 downloads available (e.g., raadszaal_2026-03-23T143101.mp4)
• HLS streams support time-based clip extraction (start= and end= parameters)
• Subtitles available (subtitles=1 parameter in m3u8 URL)
• Integrated into iBabs (Utrecht) via data-video-type="ConnectedViews"
• VOS360 CDN for streaming delivery

Sample URLs

# Live HLS
https://arbor-west-01.vos360.video/live/raadszaal/index.m3u8?subtitles=1

# VOD MP4

YouTube (varies)

Findings

Key Findings

• YouTube is supplementary, not a primary council meeting platform
• yt-dlp works for downloading recordings
• Belgian municipalities use YouTube more than Dutch ones for council recordings
• Most Dutch municipal YouTube channels are promotional, not for raadsvergaderingen

Extraction Feasibility per Platform

Priority Order for Implementation

1. NotUBiz (317 municipalities, direct MP4 API, no auth) - biggest coverage, easiest extraction
2. ConnectedViews (1 municipality, direct MP4, no auth) - trivial but small coverage
3. GemeenteOplossingen (34 municipalities, Wowza HLS, public tokens) - good coverage, needs token handling
4. iBabs native (subset of 153, player.ibabs.eu) - needs GUID extraction from HTML
5. YouTube (supplementary) - already works via yt-dlp
6. iBabs CompanyWebcast (subset of 153) - least understood, external provider
