152009-06-22 - r19250 - lavf 52.34.1 - AVFormatContext.packet_size
16 This is now an unsigned int instead of a signed int.

182009-06-19 - r19222 - lavc 52.32.0 - AVSubtitle.pts
19 Added a pts field to AVSubtitle which gives the subtitle's packet
20 PTS in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
21 not work right without this.

232009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY
24 PKT_FLAG_KEY has been deprecated and will be dropped for the next
25 major version. Use AV_PKT_FLAG_KEY instead.

272009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
28 av_lockmgr_register() can be used to register a callback function
29 that lavc (and in the future, libraries that depend on lavc) can use
30 to implement mutexes. The application should provide a callback function
31 the implements the AV_LOCK_* operations described in avcodec.h.
32 When the lock manager is registered FFmpeg is guaranteed to behave
33 correct also in a multi-threaded application.

352009-04-30 - r18719 - lavc 52.28.0 - av_free_packet
36 av_free_packet() is no longer an inline function. It is now exported.

382009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree
39 Please use NULL instead. This has been supported since r16506
40 (lavf > 52.23.1, lavc > 52.10.0).

RB
422009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
43 The old decoding functions are deprecated, all new code should use the
44 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
45 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
46 argument instead of a const uint8_t *buf / int buf_size pair.

512009-04-02 - r18317 - lavc 52.23.0 - AVPacket
52 Move AVPacket declaration from libavformat/avformat.h to

552009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
56 Make the pixel formats: PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
57 PIX_FMT_BGRA, which were defined as macros, defined as enum
58 PixelFormat values, and viceversa make PIX_FMT_RGB32,
59 PIX_FMT_RGB32_1, PIX_FMT_BGR32, PIX_FMT_BGR32_1 defined as macros.
60 Also make avcodec_get_pix_fmt() recognize the "rgb32" and "bgr32"
61 aliases.
f3370e14 62 Re-sort the enum PixelFormat list accordingly.

63 This change breaks API/ABI backward compatibility.

652009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
66 Add the enum PixelFormat values:
67 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
68 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

71 The Mersenne Twister PRNG implemented through the av_random* functions
72 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
73 instead.

752009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
76 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
77 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
78 and av_fifo_realloc2.
79 In addition, the order of the function arguments of av_fifo_generic_read
80 were changed to match av_fifo_generic_write.
81 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
82 applications, they may not use sizeof() or directly access members.

842009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
