Yurth is a user-generated video site that allows visitors to search for content based on location. The LAMP-based system includes a dynamic flash-based map that I coded to show the video locations. I also developed the data interface to import and display geo-tagged youtube videos.
For the technically curious, the Flash map communicates through the AMFPHP library with the server to get videos for a given map view extent. The map itself is generated by an instance of the UMN Mapserver. The server also exports the videos as a KML feed for view in Google Earth. Uploaded video is transcoded using the ffmpeg and associated codecs.
