1242 For audio formats with fixed frame size, the last frame
1243 no longer needs to be padded with silence, libavcodec
1244 will handle this internally (effectively all encoders
1245 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

2390 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2391 Introduce the avfilter_next() function.
2393 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2394 Change the signature of avfilter_register() to make it return an
2395 int. This is required since now the registration operation may fail.
2397 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2398 Make the pixdesc.h API public.

2422 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2423 Add a pts field to AVSubtitle which gives the subtitle packet pts
2424 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

2427 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2428 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2429 major version. Use AV_PKT_FLAG_KEY instead.
2431 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2432 av_lockmgr_register() can be used to register a callback function
2433 that lavc (and in the future, libraries that depend on lavc) can use
2434 to implement mutexes. The application should provide a callback function
2435 that implements the AV_LOCK_* operations described in avcodec.h.
2436 When the lock manager is registered, FFmpeg is guaranteed to behave
2437 correctly in a multi-threaded application.
2439 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2440 av_free_packet() is no longer an inline function. It is now exported.
2442 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2443 Please use NULL instead. This has been supported since r16506
2444 (lavf > 52.23.1, lavc > 52.10.0).
2446 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2447 The old decoding functions are deprecated, all new code should use the
2448 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2449 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2450 argument instead of a const uint8_t *buf / int buf_size pair.
2452 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2453 Introduce the av_fifo_space() function.
2455 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2456 Move AVPacket declaration from libavformat/avformat.h to
2457 libavcodec/avcodec.h.
2459 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2460 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2461 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2462 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2463 PIX_FMT_BGR32_1 are now macros.
2464 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2465 Re-sort the enum PixelFormat list accordingly.
2466 This change breaks API/ABI backward compatibility.
2468 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2469 Add the enum PixelFormat values:
2470 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2471 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2473 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2474 The Mersenne Twister PRNG implemented through the av_random* functions
2475 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2478 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2479 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2480 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2481 and av_fifo_realloc2.
2482 In addition, the order of the function arguments of av_fifo_generic_read
2483 was changed to match av_fifo_generic_write.
2484 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2485 applications, they may not use sizeof() or directly access members.
2487 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2488 Introduce a new metadata API (see av_metadata_get() and friends).
2489 The old API is now deprecated and should not be used anymore. This especially
2490 includes the following structure fields:
2491 - AVFormatContext.title
2492 - AVFormatContext.author
2493 - AVFormatContext.copyright
2494 - AVFormatContext.comment
2495 - AVFormatContext.album
2496 - AVFormatContext.year
2497 - AVFormatContext.track
2498 - AVFormatContext.genre
2501 - AVProgram.provider_name
