397 int. This is required since now the registration operation may fail.
398
399 2009-11-25 - r20603 - lavu 50.5.0 - pixdesc.h API
400 Make the pixdesc.h API public.
401
402 2009-10-27 - r20385 - lavfi 1.5.0 - AVFilter.next
403 Add a next field to AVFilter, this is used for simplifying the
404 registration and management of the registered filters.
405
406 2009-10-23 - r20356 - lavfi 1.4.1 - AVFilter.description
407 Add a description field to AVFilter.
408
409 2009-10-19 - r20302 - lavfi 1.3.0 - avfilter_make_format_list()
410 Change the interface of avfilter_make_format_list() from
411 avfilter_make_format_list(int n, ...) to
412 avfilter_make_format_list(enum PixelFormat *pix_fmts).
413
414 2009-10-18 - r20272 - lavfi 1.0.0 - avfilter_get_video_buffer()
415 Make avfilter_get_video_buffer() recursive and add the w and h
416 parameters to it.
417
418 2009-10-07 - r20189 - lavfi 0.5.1 - AVFilterPic
419 Add w and h fields to AVFilterPic.
420
421 2009-06-22 - r19250 - lavf 52.34.1 - AVFormatContext.packet_size
422 This is now an unsigned int instead of a signed int.
423
424 2009-06-19 - r19222 - lavc 52.32.0 - AVSubtitle.pts
425 Add a pts field to AVSubtitle which gives the subtitle packet pts
426 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
427 not work right without this.
428
429 2009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY
430 PKT_FLAG_KEY has been deprecated and will be dropped at the next
431 major version. Use AV_PKT_FLAG_KEY instead.
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 av_free_packet() is no longer an inline function. It is now exported.
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
498 - AVFormatContext.year
499 - AVFormatContext.track
500 - AVFormatContext.genre
501 - AVStream.language
502 - AVStream.filename
503 - AVProgram.provider_name
504 - AVProgram.name
505 - AVChapter.title
