2016-02-28 - xxxxxxx - lavc 57.27.101
  Validate AVFrame returned by get_buffer2 to have required
  planes not NULL and unused planes set to NULL as crashes
  and buffer overflow are possible with certain streams if
  that is not the case.

24 25 26 27 28 29
2016-xx-xx - xxxxxxx - lavc 57.27.100 - avcodec.h
  "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
  the reset of the ASS ReadOrder field on flush. This affects the content of
  AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
  previous entry).

30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46
2016-xx-xx - xxxxxxx - lavc 57.26.100 - avcodec.h
  Add a "sub_text_format" subtitles decoding option allowing the values "ass"
  (recommended) and "ass_with_timings" (not recommended, deprecated, default).
  The default value for this option will change to "ass" at the next major
  libavcodec version bump.

  The current default is "ass_with_timings" for compatibility. This means that
  all subtitles text decoders currently still output ASS with timings printed
  as strings in the AVSubtitles.rects[N]->ass fields.

  Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
  timing is limited to a 1/100 time base, so this is relevant for any subtitles
  format needing a bigger one), ease timing adjustments, and prevents the need
  of removing the timing from the decoded string yourself. This form is also
  known as "the Matroska form". The timing information (start time, duration)
  can be found in the AVSubtitles fields.

2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2485
  PKT_FLAG_KEY has been deprecated and will be dropped at the next

2489 2490 2491
  av_lockmgr_register() can be used to register a callback function
  that lavc (and in the future, libraries that depend on lavc) can use
  to implement mutexes. The application should provide a callback function
2492 2493 2494
  that implements the AV_LOCK_* operations described in avcodec.h.
  When the lock manager is registered, FFmpeg is guaranteed to behave
  correctly in a multi-threaded application.
2495

2496
2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()

2504 2505 2506 2507 2508
  The old decoding functions are deprecated, all new code should use the
  new functions avcodec_decode_video2(), avcodec_decode_audio3() and
  avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
  argument instead of a const uint8_t *buf / int buf_size pair.

2509
2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2510 2511

2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2517 2518 2519 2520 2521
  Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
  PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
  Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
  PIX_FMT_BGR32_1 are now macros.
  avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2522
  Re-sort the enum PixelFormat list accordingly.
2523 2524
  This change breaks API/ABI backward compatibility.

2525

2526 2527 2528 2529

2531 2532 2533 2534
  The Mersenne Twister PRNG implemented through the av_random* functions
  was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
  instead.

2535
2009-03-08 - 41dd680 - lavu 50.0.0  - AVFifoBuffer
2536 2537 2538 2539
  av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
  and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
  and av_fifo_realloc2.
  In addition, the order of the function arguments of av_fifo_generic_read
2540
  was changed to match av_fifo_generic_write.
2541 2542
  The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
  applications, they may not use sizeof() or directly access members.
2543

2544
2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2545 2546
