	Theora.org :: main - Theora, video for everyone
		Theora is a free and open video compression format from the Xiph.org Foundation.
		Theora scales from postage stamp to HD resolution, and is considered particularly competitive at low bitrates.
		The bitstream format for Theora I was frozen Thursday, 2004 July 1.

	Theora.org :: FAQ - Theora, video for everyone
		Theora is an open video codec being developed by the Xiph.org Foundation as part of their Ogg project (It is a project that aims to integrate On2's VP3 video codec, Ogg Vorbis audio codec and Ogg multimedia container formats into a multimedia solution that can compete with MPEG-4 format).
		Theora is derived directly from On2's VP3 codec; currently the two are nearly identical, varying only in framing headers, but Theora will diverge and improve from the main VP3 development lineage as time progresses.
		Theora (and all associated technologies released by the Xiph.org Foundation) is released to the public via a BSD-style license.

	Xiph.org: Ogg
		Ogg is a multimedia container format, and the native file and stream format for the Xiph.org multimedia codecs.
		In addition to encapsulation and interleave of multiple data streams, Ogg provides packet framing, error detection, and periodic timestamps for seeking, and in a small, bounded percentage bitrate overhead.
		Ogg is a stream oriented container, meaning it can be written and read in one pass, making it a natural fit for internet streaming and use in processing pipelines.

	Why Ogg Theora Matters for Internet TV - Make Television - Resource for makers, producers, publishers and developers of ...
		Ogg Theora was created by a grass roots effort (spearheaded by the Xiph.org Foundation) to combat all the patent and licensing absurdness video formats have been seeing.
		Ogg Vorbis, a sister format to the Ogg Theora video format, and whose history the Ogg Theora video format is tied to, was created by similar motivations as the PNG format.
		The Theora codec was based on the VP3 codec generously donated by On2 Technologies to the Xiph.org Foundation.

	Building an Ogg Theora camera using an FPGA and embedded Linux
		Theora is an advanced video codec that competes with MPEG-4 and other low bit-rate video compression technologies.
		In the Theora format, quantized DCT components are globally reordered before being sent out -- first, go all the DC components (average values of 8x8 blocks); then, both luma (Y) and chroma (Cb and Cr); then, all the rest, the AC components (from lower to higher spatial frequencies), each in the same order.
		And, as the 8x8 DCT processes data in 64 pixel blocks, yielding all 64 coefficients (DC and 63 AC) together, the whole frame of coefficient data has to be stored before reaching the compressor output.

	FSF - Getting started with Ogg and installing Ogg plugins
		To access streaming Ogg Vorbis and Ogg Theora files you need a media player that understands these formats.
		Using Ogg is one way to support them in their efforts and to encourage a better culture.
		If you choose Ogg Vorbis and Ogg Theora, you can listen to audio and stream video using many different media players, including free software that respects your freedom.

	Blender 3D: Noob to Pro/Creating Ogg-Theora movies using Blender - Wikibooks, collection of open-content textbooks
		There are basically two ways to generate OGG files: you can use one of the many fine video editors or you can use special conversion programs.
		A disadvantage of a video editor is they are huge pieces of software, duplicating functionality that you already used when you created your animation file/s with blender.
		To convert AVI to OGG, you can use the ffmpeg2theora software package which is available in source or binary for all relevant systems.

	Code : Pause/unpause support for Ogg Theora playback :. GarageGames
		This patch adds pause/unpause support to the Ogg Theora playback code, including console methods on GuiTheoraCtrl for pausing and unpausing playback.
		Without that patch, this code will not compile cleanly -- and even if you DO get it to compile (by commenting out references to alxPause/alxUnpause) you'll only be able to pause Ogg Theora videos that have no audio track.
		Set the playback file to an Ogg Theora file.

	Using Ogg Theora Unofficial Micro-HOWTO
		Okay, thanks to some stubbornness on my part and helpfulness on the part of people on the theora-dev mailing list, I got Ogg Theora Alpha 1 compiled up, installed, and running within a day or so of its release around 25 September 2002.
		Some experimentation and more advice from the theora-dev mailing list leads to the conclusion that the problem involves the order that the audio and video packets are coming out of mplayer in.
		Until Theora Alpha 2 (due out in another month or so) is released (possibly with a fix for this in the example encoder?) this can be worked around by using TWO mplayer processes to do the export - one for just the video (and -ao null) and the other for just the audio (-vo null).

	[No title]
		The Ogg transport bitstream is designed to provide framing, error protection and seeking structure for higher-level codec streams that consist of raw, unencapsulated data packets, such as the Vorbis audio codec or the upcoming Tarkin and Theora video codecs.
		An example for a media mapping is "Ogg Vorbis", which uses the Ogg framework to encapsulate Vorbis-encoded audio data for stream-based storage (such as files) and transport (such as TCP streams or pipes).
		Ogg does not know any specifics about the codec data except that each logical bitstream belongs to a different codec, the data from the codec comes in order and has position markers (so-called "Granule positions").

	Ogg Theora - MediaCoderWiki
		Theora is a video codec being developed by the Xiph.org Foundation as part of their Ogg project.
		In the Ogg multimedia framework, Theora provides a video layer, while Vorbis usually acts as the audio layer (Speex and FLAC can also act as audio layers).
		Theora is named for Theora Jones, Edison Carter's Controller on the Max Headroom television program.

		I have read the specification of theora and spend a long time looking over internet for this information but i couldn't find anything except that the header does not contain the number of frame because theora is supposed to be usefful to streaming.
		If you see a need to combine theora and svg, start and design a plugin architeture that allows these things to be combined and mixed.
		Hmm, no. What I did say was that to copy SWF's functionalities one would have to either use a dumb Java applet (with SVG and Theora, and whatever else you want to throw inside), or to use Ogg (with SVG and Theora, and whatever else you want to throw inside).

		Not only the Theora decoding and the YUV2RGB stuff takes time and those seem to be not the main reason why audio gets stalled (the vorbis decoder is in the same loop and it is called very frequently, also when heavy work load on theora).
		In case of the theora stream it has to be called about 20-30 times successively...
		And before you can see, if a theora frame has to be skipped (too late for decoding), you must do several pagein-calls and several other things first which also takes a lot of time.

	JRoar -- Pure Java Streaming Server for Ogg

		In current implementation, Ogg packets are thrown to the local subnet in UDP packets without any trick.

		Ogg and FLAC are two popular formats that are being used more and more.
		There are no free fixed-point decoding libraries for Ogg that would allow ARM based platforms like the Empeg and Music Keg to play those files.
		Unless you are using pre-encoded ogg files from a playlist that you don't want to reencode to a standard bitrate, you will need to include an encoding setup.

		However, currently there aren`t any broadcasting tools around to send theora to peercast (icecast+theora should be ready soon though).
		Real works best (xiph made the plugins after all) and is the easiest to use because we can make use of the.ram file extension to get the stream into the player.
		OGG Theora streams will show up as OGM in the YP to help differentiate between Vorbis only OGG streams.

		Just like its audio pendant Vorbis, Theora is patent-free and royalty-free, which means that everyone who wants to can implement it without having to pay anyone for that right.
		Apart from making the world a better and happier place, this means among other things that it is no problem for Linux distributions to ship Theora codecs.
