Raw Blame History 

  1. Never assume the API of libav* to be stable unless at least 1 week has passed since

  2. the last major version increase.

  3. The last version increases were:

  4. libavcodec:  ?

  5. libavdevice: ?

  6. libavfilter: ?

  7. libavformat: ?

  8. libpostproc: ?

  9. libswscale:  ?

  10. libavutil:   2009-03-08

  11. 

  12. 

  13. API changes, most recent first:

  14. 

  15. 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space

  16.   Introduce the av_fifo_space() function.

  17. 

  18. 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket

  19.   Move AVPacket declaration from libavformat/avformat.h to

  20.   libavcodec/avcodec.h.

  21. 

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

  23.   Make the pixel formats: PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,

  24.   PIX_FMT_BGRA, which were defined as macros, defined as enum

  25.   PixelFormat values, and viceversa make PIX_FMT_RGB32,

  26.   PIX_FMT_RGB32_1, PIX_FMT_BGR32, PIX_FMT_BGR32_1 defined as macros.

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

  28.   aliases.

  29.   Re-sort the enum PixelFormat list accordingly.

  30.   This change breaks API/ABI backward compatibility.

  31. 

  32. 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants

  33.   Add the enum PixelFormat values:

  34.   PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,

  35.   PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

  36. 

  37. 2009-03-21 - r18116 - lavu 50.0.0  - av_random*

  38.   The Mersenne Twister PRNG implemented through the av_random* functions

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

  40.   instead.

  41. 

  42. 2009-03-08 - r17869 - lavu 50.0.0  - AVFifoBuffer

  43.   av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped

  44.   and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write

  45.   and av_fifo_realloc2.

  46.   In addition, the order of the function arguments of av_fifo_generic_read

  47.   were changed to match av_fifo_generic_write.

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

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

  50. 

  51. 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API

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

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

  54.   includes the following structure fields:

  55.     - AVFormatContext.title

  56.     - AVFormatContext.author

  57.     - AVFormatContext.copyright

  58.     - AVFormatContext.comment

  59.     - AVFormatContext.album

  60.     - AVFormatContext.year

  61.     - AVFormatContext.track

  62.     - AVFormatContext.genre

  63.     - AVStream.language

  64.     - AVStream.filename

  65.     - AVProgram.provider_name

  66.     - AVProgram.name

  67.     - AVChapter.title
