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

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

  17.   new functions avcodec_decode_video2(), avcodec_decode_audio3() and

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

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

  20. 

  21. 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space

  22.   Introduce the av_fifo_space() function.

  23. 

  24. 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket

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

  26.   libavcodec/avcodec.h.

  27. 

  28. 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats

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

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

  31.   PixelFormat values, and viceversa make PIX_FMT_RGB32,

  32.   PIX_FMT_RGB32_1, PIX_FMT_BGR32, PIX_FMT_BGR32_1 defined as macros.

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

  34.   aliases.

  35.   Re-sort the enum PixelFormat list accordingly.

  36.   This change breaks API/ABI backward compatibility.

  37. 

  38. 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants

  39.   Add the enum PixelFormat values:

  40.   PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,

  41.   PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

  42. 

  43. 2009-03-21 - r18116 - lavu 50.0.0  - av_random*

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

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

  46.   instead.

  47. 

  48. 2009-03-08 - r17869 - lavu 50.0.0  - AVFifoBuffer

  49.   av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped

  50.   and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write

  51.   and av_fifo_realloc2.

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

  53.   were changed to match av_fifo_generic_write.

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

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

  56. 

  57. 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API

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

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

  60.   includes the following structure fields:

  61.     - AVFormatContext.title

  62.     - AVFormatContext.author

  63.     - AVFormatContext.copyright

  64.     - AVFormatContext.comment

  65.     - AVFormatContext.album

  66.     - AVFormatContext.year

  67.     - AVFormatContext.track

  68.     - AVFormatContext.genre

  69.     - AVStream.language

  70.     - AVStream.filename

  71.     - AVProgram.provider_name

  72.     - AVProgram.name

  73.     - AVChapter.title
