libtheora reference implementation

1.0

During TheoraMeeting200804 it was stated that before 1.0, the following should happen:

• figure out how to expose the improved theora-exp API (libtheoradec, libtheoraenc, etc.)
• rewrite the API documentation, more information besides C syntax
• think a bit more about the logo and its use policy
• integrate VS patches from Nils Pipenbrinck for the filter and idct mmx functions to match more the gcc style
• check build support on more platforms, particularly MSVC and Apple's XCode
• fix most Theora tickets in the trac
• remove debug flags (done in RC1) and add optimization ones
• add some examples (YUV4MPEG -> Theora ?), add docs for existing ones (what is it supposed to do ?)

1.0 was released on 2008-11-03.

1.1

• Improve theora-thusnelda an make it the reference implementation: see Theora "the push for 1.0" update and Theora: The push for 1.0, Thusnelda project update 20080320: xiphmont articles on theora future (actually, this will be in libtheora 1.1 not 1.0)
• complete Ogg mapping description in the spec
• update RTP mapping spec

According to the 2008-04-01 Theora meeting the '1.0' part (the theora-thusnelda trunk) is to be complete in a month or two I hope.

Theora II

• see Theora: The push for 1.0, Thusnelda project update 20080320 (beyond 1.0 spec section) and Theora "the push for 1.0" update: xiphmont articles on theora future

According to the 2008-04-01 Theora meeting that's on the six-month timeframe.

Application Support

• update binaries of XiphQT and Directshow Filters (includig fix for bug 1301)
• update and fix FFMPEG2THEORA (see Trac)

Easy Transcoding on Windows

It's difficult for some people to create theora files outside the command line. We need a simple tool that does drag-and-drop transcoding, with a gui for metadata and license marking, and some simple cleanup like crop/scale/rotate and color adjustment. This could be just a wrapper around ffmpeg2theora.

Albeit technically it would be possible (and simple) to do GUI wrapper for ffmpeg2theora it may be wiser to write a completely new application which uses DirectShow to decode the given media file. This way the encoder wouldn't have to ship with evil patented decoders and still can transcode any source the computer can play in e.g. Windows Media Player. - Maikmerten 12:06, 30 July 2007 (PDT)

Quicktime export

It is important that content creators be able to easily create theora videos.

• write a stand-alone output encoder plugin that does best-practices export
• do a gui transcode tool, a little like ffmpeg2theora, but pulling from the native quicktime decoders and writing out theora + vorbis/speex. Must have a drag and drop interface with sensible quality presets, metadata insertion. Bonus points for integrated stream sourcing and upload to various free sharing sites with appropriate CC licensing.

Misc

• prove wrong / obsolete all those 1, 2 "Theora is crap" claims

Dynamic/variable keyframing

Setting keyframes dynamically could increase both quality and compression. Have a look at this: [1].
