  1121. 

  1122. 2009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY

  1126. 2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()

  1127.   av_lockmgr_register() can be used to register a callback function

  1128.   that lavc (and in the future, libraries that depend on lavc) can use

  1129.   to implement mutexes. The application should provide a callback function

  1130.   that implements the AV_LOCK_* operations described in avcodec.h.

  1131.   When the lock manager is registered, FFmpeg is guaranteed to behave

  1132.   correctly in a multi-threaded application.

  1133. 

  1134. 2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet()

  1140. 

  1141. 2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle

  1142.   The old decoding functions are deprecated, all new code should use the

  1143.   new functions avcodec_decode_video2(), avcodec_decode_audio3() and

  1144.   avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt

  1145.   argument instead of a const uint8_t *buf / int buf_size pair.

  1146. 

  1147. 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()

  1149. 

  1150. 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket

  1151.   Move AVPacket declaration from libavformat/avformat.h to

  1152.   libavcodec/avcodec.h.

  1153. 

  1154. 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats

  1155.   Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,

  1156.   PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.

  1157.   Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and

  1158.   PIX_FMT_BGR32_1 are now macros.

  1159.   avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.

  1160.   Re-sort the enum PixelFormat list accordingly.

  1161.   This change breaks API/ABI backward compatibility.

  1162. 

  1163. 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants

  1164.   Add the enum PixelFormat values:

  1165.   PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,

  1166.   PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

  1167. 

  1168. 2009-03-21 - r18116 - lavu 50.0.0  - av_random*

  1169.   The Mersenne Twister PRNG implemented through the av_random* functions

  1170.   was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions

  1171.   instead.

  1172. 

  1173. 2009-03-08 - r17869 - lavu 50.0.0  - AVFifoBuffer

  1174.   av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped

  1175.   and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write

  1176.   and av_fifo_realloc2.

  1177.   In addition, the order of the function arguments of av_fifo_generic_read

  1178.   was changed to match av_fifo_generic_write.

  1179.   The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by

  1180.   applications, they may not use sizeof() or directly access members.

  1181. 

  1182. 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API

  1183.   Introduce a new metadata API (see av_metadata_get() and friends).

  1184.   The old API is now deprecated and should not be used anymore. This especially

  1197.     - AVProgram.name

  1198.     - AVChapter.title
