  386. av_lockmgr_register() can be used to register a callback function
  387. that lavc (and in the future, libraries that depend on lavc) can use
  388. to implement mutexes. The application should provide a callback function
  389. that implements the AV_LOCK_* operations described in avcodec.h.
  390. When the lock manager is registered, FFmpeg is guaranteed to behave
  391. correctly in a multi-threaded application.
  392. 2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet()

  394. 2009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
  395. Please use NULL instead. This has been supported since r16506
  396. (lavf > 52.23.1, lavc > 52.10.0).

  398. The old decoding functions are deprecated, all new code should use the
  399. new functions avcodec_decode_video2(), avcodec_decode_audio3() and
  400. avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
  401. argument instead of a const uint8_t *buf / int buf_size pair.
  402. 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()
  403. Introduce the av_fifo_space() function.

  406. libavcodec/avcodec.h.
  407. 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
  408. Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
  409. PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
  410. Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
  411. PIX_FMT_BGR32_1 are now macros.
  412. avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
  413. Re-sort the enum PixelFormat list accordingly.
  414. This change breaks API/ABI backward compatibility.
  415. 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
  416. Add the enum PixelFormat values:
  417. PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
  418. PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
  419. 2009-03-21 - r18116 - lavu 50.0.0 - av_random*
  420. The Mersenne Twister PRNG implemented through the av_random* functions
  421. was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
  422. instead.
  423. 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
  424. av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
  425. and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
  426. and av_fifo_realloc2.
  427. In addition, the order of the function arguments of av_fifo_generic_read
  428. was changed to match av_fifo_generic_write.
  429. The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
  430. applications, they may not use sizeof() or directly access members.
  431. 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
  432. Introduce a new metadata API (see av_metadata_get() and friends).
  433. The old API is now deprecated and should not be used anymore. This especially
  434. includes the following structure fields:
  435. - AVFormatContext.title
  436. - AVFormatContext.author
  437. - AVFormatContext.copyright
  438. - AVFormatContext.comment
  439. - AVFormatContext.album
  440. - AVFormatContext.year
