| 149 the bitstream revision to 3.2.1. Bitstreams marked 3.2.0 are | |
| 150 handled correctly by this decoder. Older decoders will show | |
| 151 a one frame sync error in the less noticeable direction. | |
| 152 | |
| 153 libtheora 1.0alpha8 (2007 September 18) | |

| 168 libtheora 1.0alpha6 (2006 May 30) | |
| 169 | |
| 170 * Merge theora-mmx simd acceleration (x86_32 and x86_64) | |
| 171 * Major RTP payload specification update | |
| 172 * Minor format specification updates | |
| 173 * Fix some spurious calls to free() instead of _ogg_free() | |
| 174 * Fix invalid array indexing in PixelLineSearch() | |
| 175 * Improve robustness against invalid input | |
| 176 * General warning cleanup | |
| 177 * The offset_y member now means what every application thought it meant | |
| 178 (offset from the top). This will mean some old files (those with a | |
| 179 non-centered image created with a buggy encoder) will display differently. | |
| 180 | |
| 181 libtheora 1.0alpha5 (2005 August 20) | |
| 182 | |
| 183 * Fixed bitrate management bugs that caused popping and encode | |
| 184 errors | |
| 185 * Fixed a crash problem with the theora_state internals not | |
| 186 being intialized properly. | |
| 187 * new utility function: | |
| 188 - theora_granule_shift() | |
| 189 * dump_video example now makes YUV4MPEG files by default, so | |
| 190 the results can be fed back to encoder_example and similar | |
| 191 tools. The old behavior is restored through the '-r' switch. | |
| 192 * ./configure now prints a summary | |
| 193 * simple unit test of the comment api under 'make check' | |
| 194 * misc code cleanup, warning and leak fixes | |
| 195 | |
| 196 libtheora 1.0alpha4 (2004 December 15) | |
| 197 | |
| 198 * first draft of the Theora I Format Specification | |
| 199 * API documentation generated from theora.h with Doxygen | |
| 200 * fix a double-update bug in the motion analysis | |
| 201 * apply the loop filter before filling motion vector border | |
| 202 in the reference frame | |
| 203 * new utility functions: | |
| 204 - theora_packet_isheader(), | |
| 205 - theora_packet_iskeyframe() | |
| 206 - theora_granule_frame() | |
| 207 * optional support for building without floating point | |
| 208 * optional support for building without encode support | |
| 209 * various build and packaging fixes | |
| 210 * pkg-config support | |
| 211 * SymbianOS build support | |
| 212 | |
| 213 libtheora 1.0alpha3 (2004 March 20) | |
| 214 | |
| 215 UPDATE: on 2004 July 1 the Theora I bitstream format was frozen. Files | |
| 216 produced by the libtheora 1.0alpha3 reference encoder will always be | |
| 217 decodable by the Theora I spec. | |
| 218 | |
| 219 * Bitstream info header FORMAT CHANGES: | |
| 220 - move the granulepos shift field to maintain byte alignment longer. | |
| 221 - reserve 5 additional bits for subsampling and interlace flags. | |
| 222 * Bitstream setup header FORMAT CHANGES: | |
| 223 - support for a range of interpolated quant matricies. | |
| 224 - include the in-loop block filter coeff. | |
| 225 * Bitsteam data packet FORMAT CHANGES: | |
| 226 - Reserve a bit for per-block Q index selection. | |
| 227 - Flip the coded image orientation for compatibility with VP3. | |
| 228 This allows lossless transcoding of VP3 content, but files | |
| 229 encoded with earlier theora releases would play upside down. | |
| 230 * example VP3 lossless transcoder | |
| 231 * optional support for libogg2 | |
| 232 * timing improvements in the example player | |
| 233 * packaging and build system updates and fixes | |
| 234 | |
| 235 libtheora 1.0alpha2 (2003 June 9) | |
| 236 | |
| 237 * bitstream FORMAT CHANGES: | |
| 238 - store the quant tables in a third setup header for | |
| 239 future encoder flexibility | |
| 240 - store the huffman tables in the third setup header | |
| 241 - add a field for marking the colorspace to the info header | |
| 242 - add crop parameters for non-multiple-of-16 frame sizes | |
| 243 - add a second vorbiscomment-style metadata header | |
| 244 * API changes to handle multiple headers with a single | |
| 245 theora_decode_header() call, like libvorbis | |
| 246 * code cleanup and minor fixes | |
| 247 * new dump_video code example/utility | |
| 248 * experimental win32 code examples | |
| 249 | |
| 250 libtheora 1.0alpha1 (2002 September 25) | |
| 251 | |
| 252 * First release of the theora reference implementation | |
| 253 * Port of the newly opened VP3 code to the Ogg container | |
| 254 * Rewrite of the code for portability and to use the libogg bitpacker | |
| 255 |
