429
2009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY
430

432

    
433
2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
434
  av_lockmgr_register() can be used to register a callback function
435
  that lavc (and in the future, libraries that depend on lavc) can use
436
  to implement mutexes. The application should provide a callback function
437
  that implements the AV_LOCK_* operations described in avcodec.h.
438
  When the lock manager is registered, FFmpeg is guaranteed to behave
439
  correctly in a multi-threaded application.
440

    
441
2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet()
442

443

    
444
2009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
445
  Please use NULL instead. This has been supported since r16506
446
  (lavf > 52.23.1, lavc > 52.10.0).
447

    
448
2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
449
  The old decoding functions are deprecated, all new code should use the
450
  new functions avcodec_decode_video2(), avcodec_decode_audio3() and
451
  avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
452
  argument instead of a const uint8_t *buf / int buf_size pair.
453

    
454
2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()
455
  Introduce the av_fifo_space() function.
456

    
457
2009-04-02 - r18317 - lavc 52.23.0 - AVPacket
458
  Move AVPacket declaration from libavformat/avformat.h to
459
  libavcodec/avcodec.h.
460

    
461
2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
462
  Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
463
  PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
464
  Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
465
  PIX_FMT_BGR32_1 are now macros.
466
  avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
467
  Re-sort the enum PixelFormat list accordingly.
468
  This change breaks API/ABI backward compatibility.
469

    
470
2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
471
  Add the enum PixelFormat values:
472
  PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
473
  PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
474

    
475
2009-03-21 - r18116 - lavu 50.0.0  - av_random*
476
  The Mersenne Twister PRNG implemented through the av_random* functions
477
  was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
478
  instead.
479

    
480
2009-03-08 - r17869 - lavu 50.0.0  - AVFifoBuffer
481
  av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
482
  and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
483
  and av_fifo_realloc2.
484
  In addition, the order of the function arguments of av_fifo_generic_read
485
  was changed to match av_fifo_generic_write.
486
  The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
487
  applications, they may not use sizeof() or directly access members.
488

    
489
2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
490
  Introduce a new metadata API (see av_metadata_get() and friends).
491
  The old API is now deprecated and should not be used anymore. This especially
492
  includes the following structure fields:
493
    - AVFormatContext.title
494
    - AVFormatContext.author
495
    - AVFormatContext.copyright
496
    - AVFormatContext.comment
497
    - AVFormatContext.album

504
    - AVProgram.name
505
    - AVChapter.title
