I have long wished to get the ability to be able to tag my media files. Please read in the context of educational audio/video lectures, e.g., a lecture series of 60 min audio files. Technology at its present state is still unable to tag such media automatically and that too considering the context of discussion.
By tag I mean at least a title, some description, start time and end time within a media (audio/video) file, and the link to media file. By clicking such a 'taglink' the user can stream within a media file and listen/view only the section meant.
If I can provide the ability to the users to create such tags, be able to search within them, present the user with search results, be able to stream relevant portion of the media by clicking a search result, ie a 'taglink' my purpose is well served.
The database for such tags is what I term as tagbase.
By presenting this idea here I wish expert users to help me do this using php/mySQL. Based on my searches till now I have failed to find any such implementation on the web.
