  Added w and h fields to AVFilterPic.

2009-06-22 - r19250 - lavf 52.34.1 - AVFormatContext.packet_size

  This is now an unsigned int instead of a signed int.

2009-06-19 - r19222 - lavc 52.32.0 - AVSubtitle.pts

  Added a pts field to AVSubtitle which gives the subtitle's packet

  PTS in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

  not work right without this.

2009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY

  PKT_FLAG_KEY has been deprecated and will be dropped for the next

  major version. Use AV_PKT_FLAG_KEY instead.

2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()

  av_lockmgr_register() can be used to register a callback function

  that lavc (and in the future, libraries that depend on lavc) can use

  to implement mutexes. The application should provide a callback function

  the implements the AV_LOCK_* operations described in avcodec.h.

  When the lock manager is registered FFmpeg is guaranteed to behave

  correct also in a multi-threaded application.

2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet

  av_free_packet() is no longer an inline function. It is now exported.

2009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree

  Please use NULL instead. This has been supported since r16506

  (lavf > 52.23.1, lavc > 52.10.0).

2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle

  The old decoding functions are deprecated, all new code should use the

  new functions avcodec_decode_video2(), avcodec_decode_audio3() and

  avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt

  argument instead of a const uint8_t *buf / int buf_size pair.

2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space

  Introduce the av_fifo_space() function.

2009-04-02 - r18317 - lavc 52.23.0 - AVPacket

  Move AVPacket declaration from libavformat/avformat.h to

  libavcodec/avcodec.h.

2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats

  Make the pixel formats: PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,

  PIX_FMT_BGRA, which were defined as macros, defined as enum

  PixelFormat values, and viceversa make PIX_FMT_RGB32,

  PIX_FMT_RGB32_1, PIX_FMT_BGR32, PIX_FMT_BGR32_1 defined as macros.

  Also make avcodec_get_pix_fmt() recognize the "rgb32" and "bgr32"

  aliases.

  Re-sort the enum PixelFormat list accordingly.

  This change breaks API/ABI backward compatibility.

2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants

  Add the enum PixelFormat values:

  PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,

  PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

2009-03-21 - r18116 - lavu 50.0.0  - av_random*

  The Mersenne Twister PRNG implemented through the av_random* functions

  was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions

  instead.

2009-03-08 - r17869 - lavu 50.0.0  - AVFifoBuffer

  av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped

  and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write

  and av_fifo_realloc2.

  In addition, the order of the function arguments of av_fifo_generic_read

  were changed to match av_fifo_generic_write.

  The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by

  applications, they may not use sizeof() or directly access members.

2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API

  Introduce a new metadata API (see av_metadata_get() and friends).

  The old API is now deprecated and should not be used anymore. This especially

  includes the following structure fields:

    - AVFormatContext.title

    - AVFormatContext.author

    - AVFormatContext.copyright

    - AVFormatContext.comment

    - AVFormatContext.album

    - AVFormatContext.year

    - AVFormatContext.track

    - AVFormatContext.genre

    - AVStream.language

    - AVStream.filename

    - AVProgram.provider_name

    - AVProgram.name

    - AVChapter.title
