  1144.   av_lockmgr_register() can be used to register a callback function

  1145.   that lavc (and in the future, libraries that depend on lavc) can use

  1146.   to implement mutexes. The application should provide a callback function

  1147.   that implements the AV_LOCK_* operations described in avcodec.h.

  1148.   When the lock manager is registered, FFmpeg is guaranteed to behave

  1149.   correctly in a multi-threaded application.

  1150.

  1160.   new functions avcodec_decode_video2(), avcodec_decode_audio3() and

  1161.   avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt

  1162.   argument instead of a const uint8_t *buf / int buf_size pair.

  1163. 

  1164. 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()

  1169.   libavcodec/avcodec.h.

  1170. 

  1171. 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats

  1172.   Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,

  1173.   PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.

  1174.   Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and

  1175.   PIX_FMT_BGR32_1 are now macros.

  1176.   avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.

  1177.   Re-sort the enum PixelFormat list accordingly.

  1178.   This change breaks API/ABI backward compatibility.

  1179. 

  1180. 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants

  1181.   Add the enum PixelFormat values:

  1182.   PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,

  1183.   PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

  1184.

  1186.   The Mersenne Twister PRNG implemented through the av_random* functions

  1187.   was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions

  1188.   instead.

  1189. 

  1190. 2009-03-08 - 41dd680 - lavu 50.0.0  - AVFifoBuffer

  1191.   av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped

  1192.   and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write

  1193.   and av_fifo_realloc2.

  1194.   In addition, the order of the function arguments of av_fifo_generic_read

  1195.   was changed to match av_fifo_generic_write.

  1196.   The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by

  1197.   applications, they may not use sizeof() or directly access members.

  1198. 

  1199. 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API

  1200.   Introduce a new metadata API (see av_metadata_get() and friends).
