283 'CodecID' identifier. Such code should either #undef CodecID or stop using the
284 CodecID name.
285
286 2012-08-03 - 239fdf1 - lavu 51.37.1 - cpu.h

1306 Introduce the avfilter_next() function.
1307
1308 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1309 Change the signature of avfilter_register() to make it return an
1310 int. This is required since now the registration operation may fail.
1311
1312 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1313 Make the pixdesc.h API public.
1314
1315 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
1316 Add a next field to AVFilter, this is used for simplifying the
1317 registration and management of the registered filters.

1332 Add w and h fields to AVFilterPic.
1333

1336
1337 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1338 Add a pts field to AVSubtitle which gives the subtitle packet pts
1339 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1340 not work right without this.
1341
1342 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1343 PKT_FLAG_KEY has been deprecated and will be dropped at the next

1345
1346 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1347 av_lockmgr_register() can be used to register a callback function
1348 that lavc (and in the future, libraries that depend on lavc) can use
1349 to implement mutexes. The application should provide a callback function
1350 that implements the AV_LOCK_* operations described in avcodec.h.
1351 When the lock manager is registered, FFmpeg is guaranteed to behave
1352 correctly in a multi-threaded application.
1353
1354 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1355 av_free_packet() is no longer an inline function. It is now exported.
1356
1357 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1358 Please use NULL instead. This has been supported since r16506
1359 (lavf > 52.23.1, lavc > 52.10.0).
1360
1361 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1362 The old decoding functions are deprecated, all new code should use the
1363 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1364 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1365 argument instead of a const uint8_t *buf / int buf_size pair.
1366
1367 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1368 Introduce the av_fifo_space() function.
1369
1370 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1371 Move AVPacket declaration from libavformat/avformat.h to
1372 libavcodec/avcodec.h.
1373
1374 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1375 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1376 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1377 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1378 PIX_FMT_BGR32_1 are now macros.
1379 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1380 Re-sort the enum PixelFormat list accordingly.
1381 This change breaks API/ABI backward compatibility.
1382
1383 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1384 Add the enum PixelFormat values:
1385 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1386 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1387
1388 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1389 The Mersenne Twister PRNG implemented through the av_random* functions
1390 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1391 instead.
1392
1393 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1394 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1395 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1396 and av_fifo_realloc2.
1397 In addition, the order of the function arguments of av_fifo_generic_read
1398 was changed to match av_fifo_generic_write.
1399 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1400 applications, they may not use sizeof() or directly access members.
1401
1402 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1403 Introduce a new metadata API (see av_metadata_get() and friends).
1404 The old API is now deprecated and should not be used anymore. This especially
1405 includes the following structure fields:
1406 - AVFormatContext.title
1407 - AVFormatContext.author
1408 - AVFormatContext.copyright
1409 - AVFormatContext.comment
1410 - AVFormatContext.album
1411 - AVFormatContext.year
1412 - AVFormatContext.track
1413 - AVFormatContext.genre
1414 - AVStream.language
1415 - AVStream.filename
1416 - AVProgram.provider_name
1417 - AVProgram.name
1418 - AVChapter.title
