Firefox Plugin Annodex For Searching Audio, Video

loser in front of a computer writes "ZDNet Australia reports that 'Australia's CSIRO research organisation has developed a Firefox plugin named Annodex that allows browsing through time-continuous media such as audio and video in the same way that HTML allows browsing through text.' I've just checked Annodex out and it's very cool. The sample video from the Perl conference is way funny too." The catch is, the media to be searched has to be prepped first.

    'Rewind' and 'fast-forward' already do this? "Time-continuous media" is odd in that it implies something like a stream, yet if the media has to be prepared first, it has to be a complete file. If I could reach the article (seems /. hosed their bandwidth?) I'd check up on this, but:

    The only implication here is that you could skip past part of a stream that exists as a preprepared complete file at the other end (as opposed to radio, which is incomplete and not browsable); but I bet the prepped file is significantly bigger, and the time saved skipping over a boring section would be replaced by the time required to download the extra data.

    Quicktime .mov files also play while still downloading, and work in more browsers than just Firefox; .mov has been around for a while, is already prepped, is easy to convert to with existing programs (free to download) and has various things like crossplatform compatibility.

      Hi, the "preprepared complete file" is not significantly bigger at all. We store things in standard Ogg bitstream file, with an additional track (logical bitstream, in Ogg speak) to store the extra metadata (CMML) that we use to store the information about each clip. The CMML is absolutely tiny in comparison to the raw audio and video; for the videos we've got there as samples, the CMML consumes perhaps only a few kilobytes (out of maybe a dozen megabytes.)

      We've designed Annodex and CMML with the Internet in mind, and have some mechanisms to keep it bandwidth-friendly. For example:

      1. If you start playback at 5 minutes into the file, you don't play the first 5 minutes: the client sends the server timed URI, and the server will start serving out the media from 5 minutes only.

      2. You can retrieve only the CMML from the media by setting a HTTP header of "Accept: text/x-cmml" in the HTTP request. We already have a proof of concept for search engines to use this, so they can search on the entire video (and create hyperlinks to the exact time points concerned -- no more scrubbing through an hour of video to get to the bits of information you were after!). The Firefox extension does this to grab the "table of contents" display from the server.

      3. We've designed Annodex to be proxy-friendly, so that they can cache the audio and video, even for media that's served out at different times.

  2. Firefox Plugins Links Thread by Douglas+Simmons · · Score: 1, Informative
    My favorite thing about stories like this is that creates fertile ground on which to find links for warez to enhance whatever the given program of discussion is. That is the purpose of this thread. Its secondary purpose is to give me some karma, as I am in a whorish mood.

    Allow me to kick it off. The following are links for Firefox browsers only as they will install themselves automagically upon click. You've been warned. A couple of these, I forgot which, install links are for the MS Windows platforms since most of you suckers use Windows even though this site is about Linux leetness.

    Autocopy saves you from having to hit ctrl+c to copy highlighted text, sort of like most remote terminal programs and irc clients
    DictionarySearch will allow you get dictionary.com definitions in a new background tab by highlighting a word, right clicking it, and in the menu you can hit Dictionary Search for "triskaidekaphobia"
    Adblock
    should be self-explanatory.
    This one will identify the current US Homeland Security terrorism threat level with a small colored box in the status bar (fun for showing off to get IE users to make the switch)
    Stock ticker. When putting in your symbols, here are a few symbols for some indices: ^NDX (nasdaq), ^DJI (dow jones industrial average), ^GSPC for the S&P 500
    LinkPreview will pop up thumbnail preview images [most of the time] when you mouseover a link. Frickin awesome. Requires restart.

    Time to stop and hit submit before this article gets too many posts so that I may maximize karma intake :). Please reply with links to your own favorite plugins/extensions.

      Your link is to an older version (1.2)

      From the changelog:
      • 1.3 - Major bug fix (random Firefox crashes), many thanks to Mark.

      So if you want to try it, better get 1.3: http://patsis.brownhost.com/hpxpi/linkpreview13.xp i

    Ive actually seen this in action and most of you are right off track. This isnt a streaming only format nore is it a DVD media replacement. It s a interactive web based media format. Imagine your watching a lecture and during the lecture lest say "Open Source" is mentioned. The author can put a pop up link in the video stream with "Learn more about Open Source" click on the link and you get a short video about open source then it goes back to the main lecture. No getting stuck having to pause the video stream while you look up a term.

    The extension is currently only for Firefox. There's no technical reason stopping it from being used Mozilla though (we use Mozilla internally to do a lot of testing); it's only that Mozilla and Firefox extensions must be packaged slightly differently, and we haven't put the time into writing the required install.js script for Mozilla yet. (It's open-source remember, so feel free to contribute and send us patches!)
