2415 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2416 Introduce the avfilter_next() function.
2418 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2419 Change the signature of avfilter_register() to make it return an
2420 int. This is required since now the registration operation may fail.
2422 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2423 Make the pixdesc.h API public.
2425 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

2447 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2448 Add a pts field to AVSubtitle which gives the subtitle packet pts
2449 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2450 not work right without this.
2452 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2453 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2454 major version. Use AV_PKT_FLAG_KEY instead.
2456 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2457 av_lockmgr_register() can be used to register a callback function
2458 that lavc (and in the future, libraries that depend on lavc) can use
2459 to implement mutexes. The application should provide a callback function
2460 that implements the AV_LOCK_* operations described in avcodec.h.
2461 When the lock manager is registered, FFmpeg is guaranteed to behave
2462 correctly in a multi-threaded application.
2464 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2465 av_free_packet() is no longer an inline function. It is now exported.
2467 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2468 Please use NULL instead. This has been supported since r16506
2469 (lavf > 52.23.1, lavc > 52.10.0).
2471 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2472 The old decoding functions are deprecated, all new code should use the
2473 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2474 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2475 argument instead of a const uint8_t *buf / int buf_size pair.
2477 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2478 Introduce the av_fifo_space() function.
2480 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2481 Move AVPacket declaration from libavformat/avformat.h to
2482 libavcodec/avcodec.h.
2484 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2485 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2486 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2487 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2488 PIX_FMT_BGR32_1 are now macros.
2489 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2490 Re-sort the enum PixelFormat list accordingly.
2491 This change breaks API/ABI backward compatibility.
2493 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2494 Add the enum PixelFormat values:
2495 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2496 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2498 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2499 The Mersenne Twister PRNG implemented through the av_random* functions
2500 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2503 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2504 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2505 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2506 and av_fifo_realloc2.
2507 In addition, the order of the function arguments of av_fifo_generic_read
2508 was changed to match av_fifo_generic_write.
2509 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2510 applications, they may not use sizeof() or directly access members.
2512 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2513 Introduce a new metadata API (see av_metadata_get() and friends).
2514 The old API is now deprecated and should not be used anymore. This especially
2515 includes the following structure fields:
2516 - AVFormatContext.title
2517 - AVFormatContext.author
2518 - AVFormatContext.copyright
2519 - AVFormatContext.comment
2520 - AVFormatContext.album
2521 - AVFormatContext.year
2522 - AVFormatContext.track
2523 - AVFormatContext.genre
2526 - AVProgram.provider_name
