1190
1191 Change the function signatures:

1391 Introduce the avfilter_next() function.
1392
1393 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1394 Change the signature of avfilter_register() to make it return an
1395 int. This is required since now the registration operation may fail.
1396
1397 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1398 Make the pixdesc.h API public.
1399
1400 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
1401 Add a next field to AVFilter, this is used for simplifying the
1402 registration and management of the registered filters.
1403
1404 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
1405 Add a description field to AVFilter.
1406
1407 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
1408 Change the interface of avfilter_make_format_list() from
1409 avfilter_make_format_list(int n, ...) to

1417 Add w and h fields to AVFilterPic.
1418
1419 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size

1421
1422 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1423 Add a pts field to AVSubtitle which gives the subtitle packet pts
1424 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1425 not work right without this.
1426
1427 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1428 PKT_FLAG_KEY has been deprecated and will be dropped at the next

1430
1431 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1432 av_lockmgr_register() can be used to register a callback function
1433 that lavc (and in the future, libraries that depend on lavc) can use
1434 to implement mutexes. The application should provide a callback function
1435 that implements the AV_LOCK_* operations described in avcodec.h.
1436 When the lock manager is registered, FFmpeg is guaranteed to behave
1437 correctly in a multi-threaded application.
1438
1439 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1440 av_free_packet() is no longer an inline function. It is now exported.
1441
1442 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1443 Please use NULL instead. This has been supported since r16506
1444 (lavf > 52.23.1, lavc > 52.10.0).
1445
1446 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1447 The old decoding functions are deprecated, all new code should use the
1448 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1449 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1450 argument instead of a const uint8_t *buf / int buf_size pair.
1451
1452 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1453 Introduce the av_fifo_space() function.
1454
1455 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1456 Move AVPacket declaration from libavformat/avformat.h to
1457 libavcodec/avcodec.h.
1458
1459 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1460 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1461 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1462 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1463 PIX_FMT_BGR32_1 are now macros.
1464 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1465 Re-sort the enum PixelFormat list accordingly.
1466 This change breaks API/ABI backward compatibility.
1467
1468 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1469 Add the enum PixelFormat values:
1470 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1471 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1472
1473 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1474 The Mersenne Twister PRNG implemented through the av_random* functions
1475 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1476 instead.
1477
1478 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1479 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1480 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1481 and av_fifo_realloc2.
1482 In addition, the order of the function arguments of av_fifo_generic_read
1483 was changed to match av_fifo_generic_write.
1484 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1485 applications, they may not use sizeof() or directly access members.
1486
1487 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1488 Introduce a new metadata API (see av_metadata_get() and friends).
1489 The old API is now deprecated and should not be used anymore. This especially
1490 includes the following structure fields:
1491 - AVFormatContext.title
1492 - AVFormatContext.author
1493 - AVFormatContext.copyright
1494 - AVFormatContext.comment
1495 - AVFormatContext.album
1496 - AVFormatContext.year
1497 - AVFormatContext.track
1498 - AVFormatContext.genre
1499 - AVStream.language
1500 - AVStream.filename
1501 - AVProgram.provider_name
1502 - AVProgram.name
1503 - AVChapter.title
