1250 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1251 Add a pts field to AVSubtitle which gives the subtitle packet pts
1252 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1253 not work right without this.
1255 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1256 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1257 major version. Use AV_PKT_FLAG_KEY instead.
1259 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1260 av_lockmgr_register() can be used to register a callback function
1261 that lavc (and in the future, libraries that depend on lavc) can use
1262 to implement mutexes. The application should provide a callback function
1263 that implements the AV_LOCK_* operations described in avcodec.h.
1264 When the lock manager is registered, FFmpeg is guaranteed to behave
1265 correctly in a multi-threaded application.
1267 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1268 av_free_packet() is no longer an inline function. It is now exported.
1270 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1271 Please use NULL instead. This has been supported since r16506
1272 (lavf > 52.23.1, lavc > 52.10.0).
1274 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1275 The old decoding functions are deprecated, all new code should use the
1276 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1277 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1278 argument instead of a const uint8_t *buf / int buf_size pair.
1280 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1281 Introduce the av_fifo_space() function.

1284 Move AVPacket declaration from libavformat/avformat.h to
1285 libavcodec/avcodec.h.
1287 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1288 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1289 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1290 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1291 PIX_FMT_BGR32_1 are now macros.
1292 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1293 Re-sort the enum PixelFormat list accordingly.
1294 This change breaks API/ABI backward compatibility.
1296 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1297 Add the enum PixelFormat values:
1298 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1299 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1301 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1302 The Mersenne Twister PRNG implemented through the av_random* functions
1303 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1306 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1307 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1308 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1309 and av_fifo_realloc2.
1310 In addition, the order of the function arguments of av_fifo_generic_read
1311 was changed to match av_fifo_generic_write.
1312 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1313 applications, they may not use sizeof() or directly access members.
1315 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
