  376. 2009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY
  377. PKT_FLAG_KEY has been deprecated and will be dropped at the next

  379. 2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
  380. av_lockmgr_register() can be used to register a callback function
  381. that lavc (and in the future, libraries that depend on lavc) can use
  382. to implement mutexes. The application should provide a callback function
  383. that implements the AV_LOCK_* operations described in avcodec.h.
  384. When the lock manager is registered, FFmpeg is guaranteed to behave
  385. correctly in a multi-threaded application.
  386. 2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet()
  387. av_free_packet() is no longer an inline function. It is now exported.
  388. 2009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
  389. Please use NULL instead. This has been supported since r16506
  390. (lavf > 52.23.1, lavc > 52.10.0).
  391. 2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
  392. The old decoding functions are deprecated, all new code should use the
  393. new functions avcodec_decode_video2(), avcodec_decode_audio3() and
  394. avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
  395. argument instead of a const uint8_t *buf / int buf_size pair.
  396. 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()
  397. Introduce the av_fifo_space() function.

  400. libavcodec/avcodec.h.
  401. 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
  402. Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
  403. PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
  404. Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
  405. PIX_FMT_BGR32_1 are now macros.
  406. avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
  407. Re-sort the enum PixelFormat list accordingly.
  408. This change breaks API/ABI backward compatibility.
  409. 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
  410. Add the enum PixelFormat values:
  411. PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
  412. PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
  413. 2009-03-21 - r18116 - lavu 50.0.0 - av_random*
  414. The Mersenne Twister PRNG implemented through the av_random* functions
  415. was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
  416. instead.
  417. 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
  418. av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
  419. and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
  420. and av_fifo_realloc2.
  421. In addition, the order of the function arguments of av_fifo_generic_read
  422. was changed to match av_fifo_generic_write.
  423. The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
  424. applications, they may not use sizeof() or directly access members.
  425. 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
  426. Introduce a new metadata API (see av_metadata_get() and friends).
  427. The old API is now deprecated and should not be used anymore. This especially
  428. includes the following structure fields:
  429. - AVFormatContext.title
  430. - AVFormatContext.author
  431. - AVFormatContext.copyright
  432. - AVFormatContext.comment
  433. - AVFormatContext.album
  434. - AVFormatContext.year
  435. - AVFormatContext.track
  436. - AVFormatContext.genre
  437. - AVStream.language
  438. - AVStream.filename
  439. - AVProgram.provider_name
