Release Notes: Better-looking videos or smaller files at the same quality. A much faster decoder. Two-pass mode for making files just the size you want them. Rigid bitrate controls trade off quality for the needs of live streaming applications.
Release Notes: There are now new separate encoder and decoder libraries supporting the new-style API based on theora-exp. Assembly optimizations were made. Documentation was improved. General robustness was increased, and many bugs were fixed.
Release Notes: This release contains build fixes from the alpha6 release. There are no new features. The new MMX asm is enabled by default, and a problem with that same code on SELinux machines has been fixed.
Release Notes: This release is an incremental update over alpha 5, consisting primarily of bugfixes and a merge of the encoder optimizations from the theora-mmx branch.
Release Notes: Bitrate management bugs that caused popping and encode errors were fixed along with a crash problem with the theora_state internals not being intialized properly. A new theora_granule_shift() utility function was added. The dump_video example now makes YUV4MPEG files by default so that results can be fed back to encoder_example and similar tools (the old behavior is restored with the '-r' switch). ./configure now prints a summary. A simple unit test of the comment API is now performed with a 'make check'. Miscellaneous code cleanups were made along with warning and leak fixes.
