  587. avfilter_make_format_list(int n, ...) to
  588. avfilter_make_format_list(enum PixelFormat *pix_fmts).
  589. 2009-10-18 - r20272 - lavfi 1.0.0 - avfilter_get_video_buffer()
  590. Make avfilter_get_video_buffer() recursive and add the w and h
  591. parameters to it.
  592. 2009-10-07 - r20189 - lavfi 0.5.1 - AVFilterPic
  593. Add w and h fields to AVFilterPic.
  594. 2009-06-22 - r19250 - lavf 52.34.1 - AVFormatContext.packet_size
  595. This is now an unsigned int instead of a signed int.
  596. 2009-06-19 - r19222 - lavc 52.32.0 - AVSubtitle.pts
  597. Add a pts field to AVSubtitle which gives the subtitle packet pts
  598. in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
  599. not work right without this.
  600. 2009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY
  601. PKT_FLAG_KEY has been deprecated and will be dropped at the next
  602. major version. Use AV_PKT_FLAG_KEY instead.
  603. 2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
  604. av_lockmgr_register() can be used to register a callback function
  605. that lavc (and in the future, libraries that depend on lavc) can use
  606. to implement mutexes. The application should provide a callback function
  607. that implements the AV_LOCK_* operations described in avcodec.h.
  608. When the lock manager is registered, FFmpeg is guaranteed to behave
  609. correctly in a multi-threaded application.
  610. 2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet()
  611. av_free_packet() is no longer an inline function. It is now exported.
  612. 2009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
  613. Please use NULL instead. This has been supported since r16506
  614. (lavf > 52.23.1, lavc > 52.10.0).
  615. 2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
  616. The old decoding functions are deprecated, all new code should use the
  617. new functions avcodec_decode_video2(), avcodec_decode_audio3() and
  618. avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
  619. argument instead of a const uint8_t *buf / int buf_size pair.
  620. 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()
  621. Introduce the av_fifo_space() function.
  622. 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket
  623. Move AVPacket declaration from libavformat/avformat.h to
  624. libavcodec/avcodec.h.
  625. 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
  626. Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
  627. PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
  628. Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
  629. PIX_FMT_BGR32_1 are now macros.
  630. avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
  631. Re-sort the enum PixelFormat list accordingly.
  632. This change breaks API/ABI backward compatibility.
  633. 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
  634. Add the enum PixelFormat values:
  635. PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
  636. PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
  637. 2009-03-21 - r18116 - lavu 50.0.0 - av_random*
  638. The Mersenne Twister PRNG implemented through the av_random* functions
  639. was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
  640. instead.
  641. 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
  642. av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
  643. and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
  644. and av_fifo_realloc2.
  645. In addition, the order of the function arguments of av_fifo_generic_read
  646. was changed to match av_fifo_generic_write.
  647. The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
  648. applications, they may not use sizeof() or directly access members.
  649. 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
  650. Introduce a new metadata API (see av_metadata_get() and friends).
  651. The old API is now deprecated and should not be used anymore. This especially
  652. includes the following structure fields:
  653. - AVFormatContext.title
  654. - AVFormatContext.author
  655. - AVFormatContext.copyright
  656. - AVFormatContext.comment
  657. - AVFormatContext.album
  658. - AVFormatContext.year
  659. - AVFormatContext.track
  660. - AVFormatContext.genre
  661. - AVStream.language
  662. - AVStream.filename
  663. - AVProgram.provider_name
  664. - AVProgram.name
  665. - AVChapter.title
