Decoder implementations

  • theora: 1.2.x versions of the reference encoder/decoder library (also known as Ptalarbvorm): theora svn, theora official releases.
  • theora-1.1: 1.1.x versions of the reference encoder/decoder library (also known as Thusnelda): theora-1.1 svn.
  • Theorarm: an Ogg Theora/Vorbis decoding library optimised for use on ARM processors: Theorarm web site. These optimizations were merged in the 1.2 reference library.
  • Leonora: Theora decoder for the C64x+ DSP coprocessor on the OMAP3 SoC manufactured by Texas Instruments. This series of SoCs is used in a variety of mobile devices including the Palm Pre, Motorola Droid, and Nokia’s N series of phones. Leonora web site. These optimizations were merged in the 1.2 reference library.
  • theora-old: old encoder/decoder library (the decoder does not support all theora features); theora version up to 1.0 alpha 7 were using this code trunk: theora-old svn.
  • theora-exp: old, no longer developed, experimental encoder/decoder library: theora-exp svn. Its improvements were merged in the 1.1.0 reference library.
  • Cortado: old, no longer developed. A GPL Java decoder for Ogg Theora, Ogg Vorbis and other codecs. Embedding this applet on your website you can give viewers access to streams from either the Flumotion streaming server or play a local file from your server without the need for a locally installed media player supporting the correct formats on the visitors computer.
