  1121.   av_lockmgr_register() can be used to register a callback function

  1122.   that lavc (and in the future, libraries that depend on lavc) can use

  1123.   to implement mutexes. The application should provide a callback function

  1124.   that implements the AV_LOCK_* operations described in avcodec.h.

  1125.   When the lock manager is registered, FFmpeg is guaranteed to behave

  1126.   correctly in a multi-threaded application.

  1127.

  1135. 2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle

  1136.   The old decoding functions are deprecated, all new code should use the

  1137.   new functions avcodec_decode_video2(), avcodec_decode_audio3() and

  1138.   avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt

  1139.   argument instead of a const uint8_t *buf / int buf_size pair.

  1140. 

  1141. 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()

  1143. 

  1144. 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket

  1145.   Move AVPacket declaration from libavformat/avformat.h to

  1146.   libavcodec/avcodec.h.

  1147. 

  1148. 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats

  1149.   Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,

  1150.   PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.

  1151.   Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and

  1152.   PIX_FMT_BGR32_1 are now macros.

  1153.   avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.

  1154.   Re-sort the enum PixelFormat list accordingly.

  1155.   This change breaks API/ABI backward compatibility.

  1156. 

  1157. 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants

  1158.   Add the enum PixelFormat values:

  1159.   PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,

  1160.   PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

  1161. 

  1162. 2009-03-21 - r18116 - lavu 50.0.0  - av_random*

  1163.   The Mersenne Twister PRNG implemented through the av_random* functions

  1164.   was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions

  1165.   instead.

  1166. 

  1167. 2009-03-08 - r17869 - lavu 50.0.0  - AVFifoBuffer

  1168.   av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped

  1169.   and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write

  1170.   and av_fifo_realloc2.

  1171.   In addition, the order of the function arguments of av_fifo_generic_read

  1172.   was changed to match av_fifo_generic_write.

  1173.   The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by

  1174.   applications, they may not use sizeof() or directly access members.

  1175. 

  1176. 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API

  1177.   Introduce a new metadata API (see av_metadata_get() and friends).
