  Add w and h fields to AVFilterPic.
154

    
155
2009-06-22 - r19250 - lavf 52.34.1 - AVFormatContext.packet_size
156

157

    
158
2009-06-19 - r19222 - lavc 52.32.0 - AVSubtitle.pts
159
  Add a pts field to AVSubtitle which gives the subtitle packet pts
160
  in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
161
  not work right without this.
162

    
163
2009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY
164
  PKT_FLAG_KEY has been deprecated and will be dropped at the next
165
  major version. Use AV_PKT_FLAG_KEY instead.
166

    
167
2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
168
  av_lockmgr_register() can be used to register a callback function
169
  that lavc (and in the future, libraries that depend on lavc) can use
170
  to implement mutexes. The application should provide a callback function
171
  that implements the AV_LOCK_* operations described in avcodec.h.
172
  When the lock manager is registered, FFmpeg is guaranteed to behave
173
  correctly in a multi-threaded application.
174

    
175
2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet
176
  av_free_packet() is no longer an inline function. It is now exported.
177

    
178
2009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree
179
  Please use NULL instead. This has been supported since r16506
180
  (lavf > 52.23.1, lavc > 52.10.0).
181

    
182
2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
183
  The old decoding functions are deprecated, all new code should use the
184
  new functions avcodec_decode_video2(), avcodec_decode_audio3() and
185
  avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
186
  argument instead of a const uint8_t *buf / int buf_size pair.
187

    
188
2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space
189
  Introduce the av_fifo_space() function.
190

    
191
2009-04-02 - r18317 - lavc 52.23.0 - AVPacket
192
  Move AVPacket declaration from libavformat/avformat.h to
193
  libavcodec/avcodec.h.
194

    
195
2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
196
  Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
197
  PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
198
  Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
199
  PIX_FMT_BGR32_1 are now macros.
200
  avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
201
  Re-sort the enum PixelFormat list accordingly.
202
  This change breaks API/ABI backward compatibility.
203

    
204
2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
205
  Add the enum PixelFormat values:
206
  PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
207
  PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
208

    
209
2009-03-21 - r18116 - lavu 50.0.0  - av_random*
210
  The Mersenne Twister PRNG implemented through the av_random* functions
211
  was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
212
  instead.
213

    
214
2009-03-08 - r17869 - lavu 50.0.0  - AVFifoBuffer
215
  av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
216
  and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
217
  and av_fifo_realloc2.
218
  In addition, the order of the function arguments of av_fifo_generic_read
219
  was changed to match av_fifo_generic_write.
220
  The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
221
  applications, they may not use sizeof() or directly access members.
222

    
223
2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
224
  Introduce a new metadata API (see av_metadata_get() and friends).
225
  The old API is now deprecated and should not be used anymore. This especially
226
  includes the following structure fields:
227
    - AVFormatContext.title
228
    - AVFormatContext.author
229
    - AVFormatContext.copyright
230
    - AVFormatContext.comment
231
    - AVFormatContext.album
232
    - AVFormatContext.year
233
    - AVFormatContext.track
234
    - AVFormatContext.genre

    - AVStream.language
236
    - AVStream.filename
237

238
    - AVProgram.name
239
    - AVChapter.title
