  1. some source links and information by bigmammoth · · Score: 4, Informative · on Mozilla Donates $100K To the Ogg Project

    hmm not the post I would have chosen for this news... Could have pointed out some of the source post announcements and avoid perpetuating a few misconceptions.

    I have heard about Theora is that it is technically inferior to many other video codecs

    Hence the need for funding the Thusnelda enhancements. Theora is a pretty solid codec and can be greatly improved with a few enhancements on the encoder side.

    I wonder if wouldn't be better to direct effort to Dirac, perhaps putting Dirac into an Ogg container

    Dirac is best at high resolution high bitrate video and not so good for standard definition low bitrate video, hence an enhanced theora is the optimal way to hit the low bandwidth target. Enabling theora to be competitive or better than others codecs in the low bitrate range in the intimidate future with relatively small investment.

    Furthermore dirac is planed for inclusion and will be explored in the tail end of this grant. (once liboggplay is more solid). Making liboggplay playback library solid will enable Dirac support to be solid as well. Since Dirac already has a maturing decoder/encoder library (Schrodinger) and already been mapped to an ogg container (what liboggplay plays).
    It's relatively easy to add in additional free codecs with ogg mappings. if( FLAC, Speex or Dirac) and will not be the primary use of the funding so its not focused in on the announcement or secondary coverage of the announcement.
    More info on the announcement here and the above mentioned links.

  3. Re:the new HTML5 element by bigmammoth · · Score: 3, Informative · on Theora 1.0 Released, Supported By Firefox
    you should take a look at the mv_embed script. Once included your embed line looks like this:

    <video src="my_video.ogg">

    This then gets rewritten to java cortado for IE clients. Or if you don't like cortado and would prefer flash fallback:

    <video>
    <source type="video/ogg" src="mymovie.ogg" />
    <source type="video/x-flv" src="mymovie.flv" />
    </video>

    Or if you want to make the video accessible with multiple downloadable video formats and multiple timed text tracks (annotations, multiple subtitle languages and what have you) all pulled from xml via JSON request (to support remote embedding) all auto-scrolled/updated with javascript based on whatever underlining playback system your browser supports:

    <video roe="my_roe_file.xml">

    (uses ROE for the xml format) presently in use in blogs such as this one

    yea ofcourse its a BSD license but given how our US patent system "works" its near impossible to "prove" that any piece of software does not have submarine patent risk.
    I did a post on this issue a while back.
    Key point is that even mpegla does not protect its clients from being sued..

  5. Re:Forget it by bigmammoth · · Score: 1 · on Council of the EU Says "We Cannot Support Linux"
    assuming this is not a troll....

    there are no working Theora VFW plugins
    Well there is the java cortado player that we use on metavid. So IE users support it out of the box. For in browser playing we also support the VLC Mozilla and IE active X plugin.

    NO video editing software supports it
    Besides the directShow filters that enable ogg theora to work in all windows media editing application and the QuickTime extension that allows ogg theora to work in all apple quicktime applications there is native cross platform ogg support in open source editors such as jahsaka and in linux editors such as cinelerra

    and finally

    no streaming server for Theora
    there is icecast which we have used on metavid.org to do live broadcasts to the java based player. Also the gstreamer flumotion suite.
