1 Never assume the API of libav* to be stable unless at least 1 month has passed
2 since the last major version increase or the API was added.

381 For audio formats with fixed frame size, the last frame
382 no longer needs to be padded with silence, libavcodec

1517 Change the signature of avfilter_register() to make it return an
1518 int. This is required since now the registration operation may fail.
1520 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1521 Make the pixdesc.h API public.

1545 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1546 Add a pts field to AVSubtitle which gives the subtitle packet pts
1547 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1548 not work right without this.
1550 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1551 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1552 major version. Use AV_PKT_FLAG_KEY instead.
1554 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1555 av_lockmgr_register() can be used to register a callback function
1556 that lavc (and in the future, libraries that depend on lavc) can use
1557 to implement mutexes. The application should provide a callback function
1558 that implements the AV_LOCK_* operations described in avcodec.h.
1559 When the lock manager is registered, FFmpeg is guaranteed to behave
1560 correctly in a multi-threaded application.
1562 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1563 av_free_packet() is no longer an inline function. It is now exported.
1565 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1566 Please use NULL instead. This has been supported since r16506
1567 (lavf > 52.23.1, lavc > 52.10.0).
1569 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1570 The old decoding functions are deprecated, all new code should use the
1571 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1572 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1573 argument instead of a const uint8_t *buf / int buf_size pair.
1575 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1576 Introduce the av_fifo_space() function.

1579 Move AVPacket declaration from libavformat/avformat.h to
1580 libavcodec/avcodec.h.
1582 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1583 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1584 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1585 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1586 PIX_FMT_BGR32_1 are now macros.
1587 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1588 Re-sort the enum PixelFormat list accordingly.
1589 This change breaks API/ABI backward compatibility.
1591 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1592 Add the enum PixelFormat values:

1594 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1596 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1597 The Mersenne Twister PRNG implemented through the av_random* functions
1598 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions

1602 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1603 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1604 and av_fifo_realloc2.
1605 In addition, the order of the function arguments of av_fifo_generic_read
1606 was changed to match av_fifo_generic_write.
1607 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1608 applications, they may not use sizeof() or directly access members.
