| michael@0 | 151 | a one frame sync error in the less noticeable direction. |
| michael@0 | 152 | |

| michael@0 | 168 | libtheora 1.0alpha6 (2006 May 30) |
| michael@0 | 169 | |
| michael@0 | 170 | * Merge theora-mmx simd acceleration (x86_32 and x86_64) |

| michael@0 | 175 | * Improve robustness against invalid input |
| michael@0 | 176 | * General warning cleanup |
| michael@0 | 177 | * The offset_y member now means what every application thought it meant |
| michael@0 | 178 | (offset from the top). This will mean some old files (those with a |
| michael@0 | 179 | non-centered image created with a buggy encoder) will display differently. |
| michael@0 | 180 | |
| michael@0 | 181 | libtheora 1.0alpha5 (2005 August 20) |
| michael@0 | 182 | |
| michael@0 | 183 | * Fixed bitrate management bugs that caused popping and encode |
| michael@0 | 184 | errors |
| michael@0 | 185 | * Fixed a crash problem with the theora_state internals not |
| michael@0 | 186 | being intialized properly. |
| michael@0 | 187 | * new utility function: |
| michael@0 | 188 | - theora_granule_shift() |
| michael@0 | 189 | * dump_video example now makes YUV4MPEG files by default, so |
| michael@0 | 190 | the results can be fed back to encoder_example and similar |
| michael@0 | 191 | tools. The old behavior is restored through the '-r' switch. |
| michael@0 | 192 | * ./configure now prints a summary |
| michael@0 | 193 | * simple unit test of the comment api under 'make check' |
| michael@0 | 194 | * misc code cleanup, warning and leak fixes |
| michael@0 | 195 | |

| michael@0 | 198 | * first draft of the Theora I Format Specification |
| michael@0 | 199 | * API documentation generated from theora.h with Doxygen |
| michael@0 | 200 | * fix a double-update bug in the motion analysis |
| michael@0 | 201 | * apply the loop filter before filling motion vector border |
| michael@0 | 202 | in the reference frame |
| michael@0 | 203 | * new utility functions: |
| michael@0 | 204 | - theora_packet_isheader(), |
| michael@0 | 205 | - theora_packet_iskeyframe() |
| michael@0 | 206 | - theora_granule_frame() |
| michael@0 | 207 | * optional support for building without floating point |
| michael@0 | 208 | * optional support for building without encode support |
| michael@0 | 209 | * various build and packaging fixes |
| michael@0 | 210 | * pkg-config support |
| michael@0 | 211 | * SymbianOS build support |
| michael@0 | 212 | |
| michael@0 | 213 | libtheora 1.0alpha3 (2004 March 20) |
| michael@0 | 214 | |
| michael@0 | 215 | UPDATE: on 2004 July 1 the Theora I bitstream format was frozen. Files |
| michael@0 | 216 | produced by the libtheora 1.0alpha3 reference encoder will always be |
| michael@0 | 217 | decodable by the Theora I spec. |
| michael@0 | 218 | |
| michael@0 | 219 | * Bitstream info header FORMAT CHANGES: |
| michael@0 | 220 | - move the granulepos shift field to maintain byte alignment longer. |
| michael@0 | 221 | - reserve 5 additional bits for subsampling and interlace flags. |
| michael@0 | 222 | * Bitstream setup header FORMAT CHANGES: |
| michael@0 | 223 | - support for a range of interpolated quant matricies. |
| michael@0 | 224 | - include the in-loop block filter coeff. |
| michael@0 | 225 | * Bitsteam data packet FORMAT CHANGES: |
| michael@0 | 226 | - Reserve a bit for per-block Q index selection. |
| michael@0 | 227 | - Flip the coded image orientation for compatibility with VP3. |
| michael@0 | 228 | This allows lossless transcoding of VP3 content, but files |
| michael@0 | 229 | encoded with earlier theora releases would play upside down. |
| michael@0 | 230 | * example VP3 lossless transcoder |
| michael@0 | 231 | * optional support for libogg2 |
| michael@0 | 232 | * timing improvements in the example player |
| michael@0 | 233 | * packaging and build system updates and fixes |
| michael@0 | 234 | |
| michael@0 | 235 | libtheora 1.0alpha2 (2003 June 9) |
| michael@0 | 236 | |
| michael@0 | 237 | * bitstream FORMAT CHANGES: |
| michael@0 | 238 | - store the quant tables in a third setup header for |
| michael@0 | 239 | future encoder flexibility |
| michael@0 | 240 | - store the huffman tables in the third setup header |
| michael@0 | 241 | - add a field for marking the colorspace to the info header |
| michael@0 | 242 | - add crop parameters for non-multiple-of-16 frame sizes |
| michael@0 | 243 | - add a second vorbiscomment-style metadata header |
| michael@0 | 244 | * API changes to handle multiple headers with a single |
| michael@0 | 245 | theora_decode_header() call, like libvorbis |
| michael@0 | 246 | * code cleanup and minor fixes |
| michael@0 | 247 | * new dump_video code example/utility |
| michael@0 | 248 | * experimental win32 code examples |
| michael@0 | 249 | |
| michael@0 | 250 | libtheora 1.0alpha1 (2002 September 25) |
| michael@0 | 251 | |
| michael@0 | 252 | * First release of the theora reference implementation |
| michael@0 | 253 | * Port of the newly opened VP3 code to the Ogg container |
| michael@0 | 254 | * Rewrite of the code for portability and to use the libogg bitpacker |
| michael@0 | 255 |
