227d1b98 DB |
126 | Add a pts field to AVSubtitle which gives the subtitle packet pts |

129 | ||
8f3f2e06 | 130 | 2009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY |

134 | 2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register() |
135 | av_lockmgr_register() can be used to register a callback function | |
136 | that lavc (and in the future, libraries that depend on lavc) can use | |
137 | to implement mutexes. The application should provide a callback function | |
227d1b98 DB |
138 | that implements the AV_LOCK_* operations described in avcodec.h. |
139 | When the lock manager is registered, FFmpeg is guaranteed to behave | |
140 | correctly in a multi-threaded application. | |

142 | 2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet |

145 | 2009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree |
146 | Please use NULL instead. This has been supported since r16506 | |
147 | (lavf > 52.23.1, lavc > 52.10.0). | |
148 | ||
2851d225 RB |
149 | 2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle |
150 | The old decoding functions are deprecated, all new code should use the | |
151 | new functions avcodec_decode_video2(), avcodec_decode_audio3() and | |
152 | avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt | |
153 | argument instead of a const uint8_t *buf / int buf_size pair. | |

155 | 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space |
156 | Introduce the av_fifo_space() function. | |
157 | ||
dd3bbb49 SS |
158 | 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket |
159 | Move AVPacket declaration from libavformat/avformat.h to | |
160 | libavcodec/avcodec.h. | |
161 | ||
5a43bbc3 | 162 | 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats |
227d1b98 DB |
163 | Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR, |
164 | PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values. | |
165 | Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and | |
166 | PIX_FMT_BGR32_1 are now macros. | |
167 | avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases. | |
f3370e14 | 168 | Re-sort the enum PixelFormat list accordingly. |
5a43bbc3 SS |
169 | This change breaks API/ABI backward compatibility. |
170 | ||
dd3bbb49 SS |
171 | 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants |
172 | Add the enum PixelFormat values: | |
173 | PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE, | |
174 | PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE. | |

c8f742ca DB |
177 | The Mersenne Twister PRNG implemented through the av_random* functions |
178 | was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions | |
179 | instead. | |

889cdae8 DB |
181 | 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer |
182 | av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped | |
183 | and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write | |
184 | and av_fifo_realloc2. | |
185 | In addition, the order of the function arguments of av_fifo_generic_read | |
227d1b98 | 186 | was changed to match av_fifo_generic_write. |
889cdae8 DB |
187 | The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by |
188 | applications, they may not use sizeof() or directly access members. | |
22d4f236 | 189 | |
889cdae8 DB |
190 | 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API |
191 | Introduce a new metadata API (see av_metadata_get() and friends). | |
192 | The old API is now deprecated and should not be used anymore. This especially | |
429d6b21 | 193 | includes the following structure fields: |
