2300 2010-01-02 - 8eb631f - lavf 52.46.0 - av_match_ext()
2301 Add av_match_ext(), it should be used in place of match_ext().
2303 2010-01-01 - a1f547b - lavf 52.45.0 - av_guess_format()
2304 Add av_guess_format(), it should be used in place of guess_format().
2306 2009-12-13 - a181981 - lavf 52.43.0 - metadata API
2307 Add av_metadata_set2(), AV_METADATA_DONT_STRDUP_KEY and
2308 AV_METADATA_DONT_STRDUP_VAL.
2310 2009-12-13 - 277c733 - lavu 50.7.0 - avstring.h API
2313 2009-12-13 - 02b398e - lavc 52.42.0 - AVStream

2317 Introduce the av_bmg_next() function.
2319 2009-12-05 - a13a543 - lavfi 1.12.0 - avfilter_draw_slice()
2320 Add a slice_dir parameter to avfilter_draw_slice().
2322 2009-11-26 - 4cc3f6a - lavfi 1.11.0 - AVFilter
2323 Remove the next field from AVFilter, this is not anymore required.
2325 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2326 Introduce the avfilter_next() function.
2328 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2329 Change the signature of avfilter_register() to make it return an
2330 int. This is required since now the registration operation may fail.
2332 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2333 Make the pixdesc.h API public.
2335 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
2336 Add a next field to AVFilter, this is used for simplifying the
2337 registration and management of the registered filters.
2339 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
2340 Add a description field to AVFilter.
2342 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
2343 Change the interface of avfilter_make_format_list() from

2347 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
2348 Make avfilter_get_video_buffer() recursive and add the w and h
2351 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
2352 Add w and h fields to AVFilterPic.
2354 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
2355 This is now an unsigned int instead of a signed int.
2357 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2358 Add a pts field to AVSubtitle which gives the subtitle packet pts
2359 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2360 not work right without this.
2362 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2363 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2364 major version. Use AV_PKT_FLAG_KEY instead.
2366 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2367 av_lockmgr_register() can be used to register a callback function
2368 that lavc (and in the future, libraries that depend on lavc) can use
2369 to implement mutexes. The application should provide a callback function
2370 that implements the AV_LOCK_* operations described in avcodec.h.
2371 When the lock manager is registered, FFmpeg is guaranteed to behave
2372 correctly in a multi-threaded application.
2374 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2375 av_free_packet() is no longer an inline function. It is now exported.
2377 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2378 Please use NULL instead. This has been supported since r16506
2379 (lavf > 52.23.1, lavc > 52.10.0).
2381 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2382 The old decoding functions are deprecated, all new code should use the
2383 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2384 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2385 argument instead of a const uint8_t *buf / int buf_size pair.
2387 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2388 Introduce the av_fifo_space() function.
2390 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2391 Move AVPacket declaration from libavformat/avformat.h to
2392 libavcodec/avcodec.h.
2394 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2395 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2396 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2397 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2398 PIX_FMT_BGR32_1 are now macros.
2399 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2400 Re-sort the enum PixelFormat list accordingly.
2401 This change breaks API/ABI backward compatibility.
2403 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2404 Add the enum PixelFormat values:
2405 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2406 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2408 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2409 The Mersenne Twister PRNG implemented through the av_random* functions
2410 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2413 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2414 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2415 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2416 and av_fifo_realloc2.
2417 In addition, the order of the function arguments of av_fifo_generic_read
2418 was changed to match av_fifo_generic_write.
2419 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2420 applications, they may not use sizeof() or directly access members.
2422 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2423 Introduce a new metadata API (see av_metadata_get() and friends).
2424 The old API is now deprecated and should not be used anymore. This especially
2425 includes the following structure fields:
2426 - AVFormatContext.title
2427 - AVFormatContext.author
2428 - AVFormatContext.copyright
2429 - AVFormatContext.comment
2430 - AVFormatContext.album
2431 - AVFormatContext.year
2432 - AVFormatContext.track
2433 - AVFormatContext.genre
2436 - AVProgram.provider_name
