1425 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1426 Change the signature of avfilter_register() to make it return an
1427 int. This is required since now the registration operation may fail.
1429 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1430 Make the pixdesc.h API public.

1454 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1455 Add a pts field to AVSubtitle which gives the subtitle packet pts
1456 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1457 not work right without this.
1459 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1460 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1461 major version. Use AV_PKT_FLAG_KEY instead.
1463 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1464 av_lockmgr_register() can be used to register a callback function
1465 that lavc (and in the future, libraries that depend on lavc) can use
1466 to implement mutexes. The application should provide a callback function
1467 that implements the AV_LOCK_* operations described in avcodec.h.
1468 When the lock manager is registered, FFmpeg is guaranteed to behave
1469 correctly in a multi-threaded application.
1471 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1472 av_free_packet() is no longer an inline function. It is now exported.
1474 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1475 Please use NULL instead. This has been supported since r16506
1476 (lavf > 52.23.1, lavc > 52.10.0).
1478 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1479 The old decoding functions are deprecated, all new code should use the
1480 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1481 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1482 argument instead of a const uint8_t *buf / int buf_size pair.
1484 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1485 Introduce the av_fifo_space() function.
1487 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1488 Move AVPacket declaration from libavformat/avformat.h to
1489 libavcodec/avcodec.h.
1491 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1492 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1493 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1494 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1495 PIX_FMT_BGR32_1 are now macros.
1496 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1497 Re-sort the enum PixelFormat list accordingly.
1498 This change breaks API/ABI backward compatibility.
1500 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1501 Add the enum PixelFormat values:
1502 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1503 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1505 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1506 The Mersenne Twister PRNG implemented through the av_random* functions
1507 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1510 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1511 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1512 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1513 and av_fifo_realloc2.
1514 In addition, the order of the function arguments of av_fifo_generic_read
1515 was changed to match av_fifo_generic_write.
1516 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1517 applications, they may not use sizeof() or directly access members.
1519 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1520 Introduce a new metadata API (see av_metadata_get() and friends).
1521 The old API is now deprecated and should not be used anymore. This especially
1522 includes the following structure fields:
1523 - AVFormatContext.title
1524 - AVFormatContext.author
1525 - AVFormatContext.copyright
1526 - AVFormatContext.comment
1527 - AVFormatContext.album
1528 - AVFormatContext.year
1529 - AVFormatContext.track
1530 - AVFormatContext.genre
1533 - AVProgram.provider_name
