2303 Add av_metadata_set2(), AV_METADATA_DONT_STRDUP_KEY and
2304 AV_METADATA_DONT_STRDUP_VAL.
2306 2009-12-13 - 277c733 - lavu 50.7.0 - avstring.h API

2318 2009-11-26 - 4cc3f6a - lavfi 1.11.0 - AVFilter
2319 Remove the next field from AVFilter, this is not anymore required.
2321 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2322 Introduce the avfilter_next() function.
2324 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2325 Change the signature of avfilter_register() to make it return an
2326 int. This is required since now the registration operation may fail.
2328 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2329 Make the pixdesc.h API public.
2331 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
2332 Add a next field to AVFilter, this is used for simplifying the
2333 registration and management of the registered filters.
2335 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
2336 Add a description field to AVFilter.
2338 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
2339 Change the interface of avfilter_make_format_list() from

2343 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
2344 Make avfilter_get_video_buffer() recursive and add the w and h
2347 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
2348 Add w and h fields to AVFilterPic.
2350 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
2351 This is now an unsigned int instead of a signed int.
2353 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2354 Add a pts field to AVSubtitle which gives the subtitle packet pts
2355 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2356 not work right without this.
2358 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2359 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2360 major version. Use AV_PKT_FLAG_KEY instead.
2362 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2363 av_lockmgr_register() can be used to register a callback function
2364 that lavc (and in the future, libraries that depend on lavc) can use
2365 to implement mutexes. The application should provide a callback function
2366 that implements the AV_LOCK_* operations described in avcodec.h.
2367 When the lock manager is registered, FFmpeg is guaranteed to behave
2368 correctly in a multi-threaded application.
2370 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2371 av_free_packet() is no longer an inline function. It is now exported.
2373 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2374 Please use NULL instead. This has been supported since r16506
2375 (lavf > 52.23.1, lavc > 52.10.0).
2377 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2378 The old decoding functions are deprecated, all new code should use the
2379 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2380 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2381 argument instead of a const uint8_t *buf / int buf_size pair.
2383 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2384 Introduce the av_fifo_space() function.
2386 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2387 Move AVPacket declaration from libavformat/avformat.h to
2388 libavcodec/avcodec.h.
2390 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2391 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2392 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2393 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2394 PIX_FMT_BGR32_1 are now macros.
2395 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2396 Re-sort the enum PixelFormat list accordingly.
2397 This change breaks API/ABI backward compatibility.
2399 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2400 Add the enum PixelFormat values:
2401 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2402 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2404 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2405 The Mersenne Twister PRNG implemented through the av_random* functions
2406 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2409 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2410 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2411 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2412 and av_fifo_realloc2.
2413 In addition, the order of the function arguments of av_fifo_generic_read
2414 was changed to match av_fifo_generic_write.
2415 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2416 applications, they may not use sizeof() or directly access members.
2418 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2419 Introduce a new metadata API (see av_metadata_get() and friends).
2420 The old API is now deprecated and should not be used anymore. This especially
2421 includes the following structure fields:
2422 - AVFormatContext.title
2423 - AVFormatContext.author
2424 - AVFormatContext.copyright
2425 - AVFormatContext.comment
2426 - AVFormatContext.album
2427 - AVFormatContext.year
2428 - AVFormatContext.track
2429 - AVFormatContext.genre
2432 - AVProgram.provider_name
