  689. 2009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY
  690. PKT_FLAG_KEY has been deprecated and will be dropped at the next

  692. 2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
  693. av_lockmgr_register() can be used to register a callback function
  694. that lavc (and in the future, libraries that depend on lavc) can use
  695. to implement mutexes. The application should provide a callback function
  696. that implements the AV_LOCK_* operations described in avcodec.h.
  697. When the lock manager is registered, FFmpeg is guaranteed to behave
  698. correctly in a multi-threaded application.
  699. 2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet()
  700. av_free_packet() is no longer an inline function. It is now exported.
  701. 2009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
  702. Please use NULL instead. This has been supported since r16506
  703. (lavf > 52.23.1, lavc > 52.10.0).
  704. 2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
  705. The old decoding functions are deprecated, all new code should use the
  706. new functions avcodec_decode_video2(), avcodec_decode_audio3() and
  707. avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
  708. argument instead of a const uint8_t *buf / int buf_size pair.
  709. 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()
  710. Introduce the av_fifo_space() function.
  711. 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket
  712. Move AVPacket declaration from libavformat/avformat.h to
  713. libavcodec/avcodec.h.
  714. 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
  715. Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
  716. PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
  717. Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
  718. PIX_FMT_BGR32_1 are now macros.
  719. avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
  720. Re-sort the enum PixelFormat list accordingly.
  721. This change breaks API/ABI backward compatibility.
  722. 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
  723. Add the enum PixelFormat values:
  724. PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
  725. PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
  726. 2009-03-21 - r18116 - lavu 50.0.0 - av_random*
  727. The Mersenne Twister PRNG implemented through the av_random* functions
  728. was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
  729. instead.
  730. 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
  731. av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
  732. and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
  733. and av_fifo_realloc2.
  734. In addition, the order of the function arguments of av_fifo_generic_read
  735. was changed to match av_fifo_generic_write.
  736. The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
  737. applications, they may not use sizeof() or directly access members.
  738. 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
  739. Introduce a new metadata API (see av_metadata_get() and friends).
  740. The old API is now deprecated and should not be used anymore. This especially
  741. includes the following structure fields:
  742. - AVFormatContext.title
  743. - AVFormatContext.author
  744. - AVFormatContext.copyright
  745. - AVFormatContext.comment
  746. - AVFormatContext.album
  747. - AVFormatContext.year
  748. - AVFormatContext.track
  749. - AVFormatContext.genre
  750. - AVStream.language
  751. - AVStream.filename
  752. - AVProgram.provider_name
  753. - AVProgram.name
