1 libtheora 1.0alph6 (2006 May 30)
3 * Merge theora-mmx simd acceleration (x86_32 and x86_64)
4 * Major RTP payload specification update
5 * Minor format specification updates
6 * Fix some spurious calls to free() instead of _ogg_free()
7 * Fix invalid array indexing in PixelLineSearch()
8 * Improve robustness against invalid input
9 * General warning cleanup
10 * The offset_y member now means what every application thought it meant
11 (offset from the top). This will mean some old files (those with a
12 non-centered image created with a buggy encoder) will display differently.
14 libtheora 1.0alpha5 (2005 August 20)
16 * Fixed bitrate management bugs that caused popping and encode
18 * Fixed a crash problem with the theora_state internals not
19 being intialized properly.
20 * new utility function:
21 - theora_granule_shift()
22 * dump_video example now makes YUV4MPEG files by default, so
23 the results can be fed back to encoder_example and similar
24 tools. The old behavior is restored through the '-r' switch.
25 * ./configure now prints a summary
26 * simple unit test of the comment api under 'make check'
27 * misc code cleanup, warning and leak fixes
29 libtheora 1.0alpha4 (2004 December 15)
31 * first draft of the Theora I Format Specification
32 * API documentation generated from theora.h with Doxygen
33 * fix a double-update bug in the motion analysis
34 * apply the loop filter before filling motion vector border
35 in the reference frame
36 * new utility functions:
37 - theora_packet_isheader(),
38 - theora_packet_iskeyframe()
39 - theora_granule_frame()
40 * optional support for building without floating point
41 * optional support for building without encode support
42 * various build and packaging fixes
44 * SymbianOS build support
46 libtheora 1.0alpha3 (2004 March 20)
48 UPDATE: on 2004 July 1 the Theora I bitstream format was frozen. Files
49 produced by the libtheora 1.0alpha3 reference encoder will always be
50 decodable by the Theora I spec.
52 * Bitstream info header FORMAT CHANGES:
53 - move the granulepos shift field to maintain byte alignment longer.
54 - reserve 5 additional bits for subsampling and interlace flags.
55 * Bitstream setup header FORMAT CHANGES:
56 - support for a range of interpolated quant matricies.
57 - include the in-loop block filter coeff.
58 * Bitsteam data packet FORMAT CHANGES:
59 - Reserve a bit for per-block Q index selection.
60 - Flip the coded image orientation for compatibility with VP3.
61 This allows lossless transcoding of VP3 content, but files
62 encoded with earlier theora releases would play upside down.
63 * example VP3 lossless transcoder
64 * optional support for libogg2
65 * timing improvements in the example player
66 * packaging and build system updates and fixes
68 libtheora 1.0alpha2 (2003 June 9)
70 * bitstream FORMAT CHANGES:
71 - store the quant tables in a third setup header for
72 future encoder flexibility
73 - store the huffman tables in the third setup header
74 - add a field for marking the colorspace to the info header
75 - add crop parameters for non-multiple-of-16 frame sizes
76 - add a second vorbiscomment-style metadata header
77 * API changes to handle multiple headers with a single
78 theora_decode_header() call, like libvorbis
79 * code cleanup and minor fixes
80 * new dump_video code example/utility
81 * experimental win32 code examples
83 libtheora 1.0alpha1 (2002 September 25)
85 * First release of the theora reference implementation
86 * Port of the newly opened VP3 code to the Ogg container
87 * Rewrite of the code for portability and to use the libogg bitpacker
