  1. Never assume the API of libav* to be stable unless at least 1 month has passed
  2. since the last major version increase.
  3. The last version increases were:
  4. libavcodec: 2011-04-18
  5. libavdevice: 2011-04-18
  6. libavfilter: 2011-04-18
  7. libavformat: 2011-04-18
  8. libpostproc: 2011-04-18 (deprecated, to be removed later)
  9. libswscale: 2011-06-20
  10. libavutil: 2011-04-18
  11. API changes, most recent first:
  12. 2012-01-xx - xxxxxxx - lavfi 2.15.0
  13. Add a new installed header -- libavfilter/version.h -- with version macros.
  14. 2011-01-03 - b73ec05 - lavu 51.21.0
  15. Add av_popcount64
  16. 2011-12-25 - lavfi 2.14.0
  17. e1d9dbf Add a new installed header - buffersrc.h
  18. It contains a new function av_buffersrc_buffer() that allows passing
  19. frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()
  20. it allows for direct rendering.
  21. 1c9e340 Add avfilter_copy_frame_props() for copying properties from
  22. AVFrame to AVFilterBufferRef.
  23. 2011-12-25 - lavc 53.31.0
  24. Add the following new fields to AVFrame:
  25. b58dbb5 sample_aspect_ratio
  26. 3a2ddf7 width, height
  27. 8a4a5f6 format
  28. 2011-12-18 - 8400b12 - lavc 53.28.1

  36. Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().
  37. avcodec_decode_audio4() writes output samples to an AVFrame, which allows
  38. audio decoders to use get_buffer().
  39. 2011-12-04 - 560f773 - lavc 53.24.0
  40. Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

  51. which is accessed from a new field, AVCodecContext.internal.
  52. - fields moved:
  53. AVCodecContext.internal_buffer --> AVCodecInternal.buffer
  54. AVCodecContext.internal_buffer_count --> AVCodecInternal.buffer_count
  55. AVCodecContext.is_copy --> AVCodecInternal.is_copy
  56. 2011-11-16 - 6270671 - lavu 51.16.0
  57. Add av_timegm()

  677. 2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
  678. av_lockmgr_register() can be used to register a callback function
  679. that lavc (and in the future, libraries that depend on lavc) can use
  680. to implement mutexes. The application should provide a callback function
  681. that implements the AV_LOCK_* operations described in avcodec.h.
  682. When the lock manager is registered, FFmpeg is guaranteed to behave
  683. correctly in a multi-threaded application.
  684. 2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet()
  685. av_free_packet() is no longer an inline function. It is now exported.
  686. 2009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
  687. Please use NULL instead. This has been supported since r16506
  688. (lavf > 52.23.1, lavc > 52.10.0).
  689. 2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
  690. The old decoding functions are deprecated, all new code should use the
  691. new functions avcodec_decode_video2(), avcodec_decode_audio3() and
  692. avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
  693. argument instead of a const uint8_t *buf / int buf_size pair.
  694. 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()
  695. Introduce the av_fifo_space() function.

  698. libavcodec/avcodec.h.
  699. 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
  700. Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
  701. PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
  702. Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
  703. PIX_FMT_BGR32_1 are now macros.
  704. avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
  705. Re-sort the enum PixelFormat list accordingly.
  706. This change breaks API/ABI backward compatibility.
  707. 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
  708. Add the enum PixelFormat values:
  709. PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
  710. PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
  711. 2009-03-21 - r18116 - lavu 50.0.0 - av_random*
  712. The Mersenne Twister PRNG implemented through the av_random* functions
  713. was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
  714. instead.
  715. 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
  716. av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
  717. and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
  718. and av_fifo_realloc2.
  719. In addition, the order of the function arguments of av_fifo_generic_read
  720. was changed to match av_fifo_generic_write.
  721. The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
  722. applications, they may not use sizeof() or directly access members.
  723. 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
  724. Introduce a new metadata API (see av_metadata_get() and friends).
  725. The old API is now deprecated and should not be used anymore. This especially
  726. includes the following structure fields:
  727. - AVFormatContext.title
  728. - AVFormatContext.author
  729. - AVFormatContext.copyright
  730. - AVFormatContext.comment
  731. - AVFormatContext.album
  732. - AVFormatContext.year
  733. - AVFormatContext.track
  734. - AVFormatContext.genre
  735. - AVStream.language
  736. - AVStream.filename
