544 it allows for direct rendering.
545 1c9e340 Add avfilter_copy_frame_props() for copying properties from
546 AVFrame to AVFilterBufferRef.

568 2011-12-04 - 560f773 - lavc 53.24.0
569 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

1384 Introduce the avfilter_next() function.
1385
1386 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1387 Change the signature of avfilter_register() to make it return an
1388 int. This is required since now the registration operation may fail.
1389
1390 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1391 Make the pixdesc.h API public.
1392
1393 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
1394 Add a next field to AVFilter, this is used for simplifying the
1395 registration and management of the registered filters.
1396
1397 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
1398 Add a description field to AVFilter.
1399
1400 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
1401 Change the interface of avfilter_make_format_list() from
1402 avfilter_make_format_list(int n, ...) to
1403 avfilter_make_format_list(enum PixelFormat *pix_fmts).
1404
1405 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()

1409 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
1410 Add w and h fields to AVFilterPic.
1411
1412 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1413 This is now an unsigned int instead of a signed int.
1414
1415 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1416 Add a pts field to AVSubtitle which gives the subtitle packet pts
1417 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1418 not work right without this.
1419
1420 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1421 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1422 major version. Use AV_PKT_FLAG_KEY instead.
1423
1424 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1425 av_lockmgr_register() can be used to register a callback function
1426 that lavc (and in the future, libraries that depend on lavc) can use
1427 to implement mutexes. The application should provide a callback function
1428 that implements the AV_LOCK_* operations described in avcodec.h.
1429 When the lock manager is registered, FFmpeg is guaranteed to behave
1430 correctly in a multi-threaded application.
1431
1432 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1433 av_free_packet() is no longer an inline function. It is now exported.
1434
1435 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1436 Please use NULL instead. This has been supported since r16506
1437 (lavf > 52.23.1, lavc > 52.10.0).
1438
1439 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1440 The old decoding functions are deprecated, all new code should use the
1441 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1442 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1443 argument instead of a const uint8_t *buf / int buf_size pair.
1444
1445 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1446 Introduce the av_fifo_space() function.
1447
1448 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1449 Move AVPacket declaration from libavformat/avformat.h to
1450 libavcodec/avcodec.h.
1451
1452 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1453 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1454 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1455 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1456 PIX_FMT_BGR32_1 are now macros.
1457 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1458 Re-sort the enum PixelFormat list accordingly.
1459 This change breaks API/ABI backward compatibility.
1460
1461 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1462 Add the enum PixelFormat values:
1463 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1464 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1465
1466 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1467 The Mersenne Twister PRNG implemented through the av_random* functions
1468 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1469 instead.
1470
1471 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1472 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1473 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1474 and av_fifo_realloc2.
1475 In addition, the order of the function arguments of av_fifo_generic_read
1476 was changed to match av_fifo_generic_write.
1477 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1478 applications, they may not use sizeof() or directly access members.
1479
1480 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1481 Introduce a new metadata API (see av_metadata_get() and friends).
1482 The old API is now deprecated and should not be used anymore. This especially
1483 includes the following structure fields:
1484 - AVFormatContext.title
1485 - AVFormatContext.author
1486 - AVFormatContext.copyright
1487 - AVFormatContext.comment
1488 - AVFormatContext.album
1489 - AVFormatContext.year
1490 - AVFormatContext.track
1491 - AVFormatContext.genre
1492 - AVStream.language
1493 - AVStream.filename
1494 - AVProgram.provider_name
1495 - AVProgram.name
1496 - AVChapter.title
