1306 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1307 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1308 major version. Use AV_PKT_FLAG_KEY instead.
1310 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1311 av_lockmgr_register() can be used to register a callback function
1312 that lavc (and in the future, libraries that depend on lavc) can use
1313 to implement mutexes. The application should provide a callback function
1314 that implements the AV_LOCK_* operations described in avcodec.h.
1315 When the lock manager is registered, FFmpeg is guaranteed to behave
1316 correctly in a multi-threaded application.
1318 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1319 av_free_packet() is no longer an inline function. It is now exported.
1321 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1322 Please use NULL instead. This has been supported since r16506
1323 (lavf > 52.23.1, lavc > 52.10.0).
1325 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1326 The old decoding functions are deprecated, all new code should use the
1327 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1328 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1329 argument instead of a const uint8_t *buf / int buf_size pair.
1331 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1332 Introduce the av_fifo_space() function.
1334 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1335 Move AVPacket declaration from libavformat/avformat.h to
1336 libavcodec/avcodec.h.
1338 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1339 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1340 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1341 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1342 PIX_FMT_BGR32_1 are now macros.
1343 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1344 Re-sort the enum PixelFormat list accordingly.
1345 This change breaks API/ABI backward compatibility.
1347 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1348 Add the enum PixelFormat values:
1349 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1350 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1352 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1353 The Mersenne Twister PRNG implemented through the av_random* functions
1354 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1357 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1358 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1359 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1360 and av_fifo_realloc2.
1361 In addition, the order of the function arguments of av_fifo_generic_read
1362 was changed to match av_fifo_generic_write.
1363 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1364 applications, they may not use sizeof() or directly access members.
1366 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1367 Introduce a new metadata API (see av_metadata_get() and friends).
1368 The old API is now deprecated and should not be used anymore. This especially
1369 includes the following structure fields:
1370 - AVFormatContext.title
1371 - AVFormatContext.author
1372 - AVFormatContext.copyright
1373 - AVFormatContext.comment
1374 - AVFormatContext.album
1375 - AVFormatContext.year
1376 - AVFormatContext.track
1377 - AVFormatContext.genre
1380 - AVProgram.provider_name
