Application Support

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.

Dynamic/variable keyframing

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

That paper is not really applicable any more. Libtheora tracks an estimated cost of coding a frames as an intra and will switch if its expects a net win. In multi-pass encoding we could use this data for optimal placement (via Dijkstra over the directed graph formed by all possible keyframe constraint windows in all contiguous segments where the estimated cost of using a keyframe is positive), although preliminary testing didn't show much benefit. This may be due to accuracy problems in the current estimates.
