2 since the last major version increase.

304 'CodecID' identifier. Such code should either #undef CodecID or stop using the
305 CodecID name.
306
307 2012-08-03 - 239fdf1 - lavu 51.37.1 - cpu.h

365 For audio formats with fixed frame size, the last frame
366 no longer needs to be padded with silence, libavcodec
367 will handle this internally (effectively all encoders

1327 Introduce the avfilter_next() function.
1328
1329 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1330 Change the signature of avfilter_register() to make it return an

1332
1333 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1334 Make the pixdesc.h API public.

1357
1358 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1359 Add a pts field to AVSubtitle which gives the subtitle packet pts
1360 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1361 not work right without this.
1362
1363 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1364 PKT_FLAG_KEY has been deprecated and will be dropped at the next

1366
1367 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1368 av_lockmgr_register() can be used to register a callback function
1369 that lavc (and in the future, libraries that depend on lavc) can use
1370 to implement mutexes. The application should provide a callback function
1371 that implements the AV_LOCK_* operations described in avcodec.h.
1372 When the lock manager is registered, FFmpeg is guaranteed to behave
1373 correctly in a multi-threaded application.
1374
1375 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1376 av_free_packet() is no longer an inline function. It is now exported.
1377
1378 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1379 Please use NULL instead. This has been supported since r16506
1380 (lavf > 52.23.1, lavc > 52.10.0).
1381
1382 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1383 The old decoding functions are deprecated, all new code should use the
1384 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1385 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1386 argument instead of a const uint8_t *buf / int buf_size pair.
1387
1388 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1389 Introduce the av_fifo_space() function.
1390
1391 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket

1393 libavcodec/avcodec.h.
1394
1395 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1396 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1397 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1398 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1399 PIX_FMT_BGR32_1 are now macros.
1400 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1401 Re-sort the enum PixelFormat list accordingly.
1402 This change breaks API/ABI backward compatibility.
1403
1404 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1405 Add the enum PixelFormat values:
1406 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1407 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1408
1409 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1410 The Mersenne Twister PRNG implemented through the av_random* functions
1411 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1412 instead.
1413
1414 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1415 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1416 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1417 and av_fifo_realloc2.
1418 In addition, the order of the function arguments of av_fifo_generic_read
1419 was changed to match av_fifo_generic_write.
1420 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1421 applications, they may not use sizeof() or directly access members.
1422
1423 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1424 Introduce a new metadata API (see av_metadata_get() and friends).
1425 The old API is now deprecated and should not be used anymore. This especially
1426 includes the following structure fields:
1427 - AVFormatContext.title
1428 - AVFormatContext.author
1429 - AVFormatContext.copyright
1430 - AVFormatContext.comment
1431 - AVFormatContext.album
1432 - AVFormatContext.year
1433 - AVFormatContext.track
1434 - AVFormatContext.genre
1435 - AVStream.language
1436 - AVStream.filename
1437 - AVProgram.provider_name
1438 - AVProgram.name
1439 - AVChapter.title
