2298 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2299 Change the signature of avfilter_register() to make it return an
2300 int. This is required since now the registration operation may fail.
2302 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2303 Make the pixdesc.h API public.
2305 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
2306 Add a next field to AVFilter, this is used for simplifying the
2307 registration and management of the registered filters.
2309 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
2310 Add a description field to AVFilter.
2312 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
2313 Change the interface of avfilter_make_format_list() from
2314 avfilter_make_format_list(int n, ...) to
2315 avfilter_make_format_list(enum PixelFormat *pix_fmts).
2317 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
2318 Make avfilter_get_video_buffer() recursive and add the w and h
2321 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
2322 Add w and h fields to AVFilterPic.
2324 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
2325 This is now an unsigned int instead of a signed int.
2327 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2328 Add a pts field to AVSubtitle which gives the subtitle packet pts
2329 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2330 not work right without this.
2332 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2333 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2334 major version. Use AV_PKT_FLAG_KEY instead.
2336 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2337 av_lockmgr_register() can be used to register a callback function
2338 that lavc (and in the future, libraries that depend on lavc) can use
2339 to implement mutexes. The application should provide a callback function
2340 that implements the AV_LOCK_* operations described in avcodec.h.
2341 When the lock manager is registered, FFmpeg is guaranteed to behave
2342 correctly in a multi-threaded application.
2344 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2345 av_free_packet() is no longer an inline function. It is now exported.
2347 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2348 Please use NULL instead. This has been supported since r16506
2349 (lavf > 52.23.1, lavc > 52.10.0).
2351 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2352 The old decoding functions are deprecated, all new code should use the
2353 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2354 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2355 argument instead of a const uint8_t *buf / int buf_size pair.
2357 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2358 Introduce the av_fifo_space() function.
2360 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2361 Move AVPacket declaration from libavformat/avformat.h to
2362 libavcodec/avcodec.h.
2364 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2365 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2366 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2367 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2368 PIX_FMT_BGR32_1 are now macros.
2369 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2370 Re-sort the enum PixelFormat list accordingly.
2371 This change breaks API/ABI backward compatibility.
2373 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2374 Add the enum PixelFormat values:
2375 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2376 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2378 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2379 The Mersenne Twister PRNG implemented through the av_random* functions
2380 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2383 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2384 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2385 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2386 and av_fifo_realloc2.
2387 In addition, the order of the function arguments of av_fifo_generic_read
2388 was changed to match av_fifo_generic_write.
2389 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2390 applications, they may not use sizeof() or directly access members.
2392 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2393 Introduce a new metadata API (see av_metadata_get() and friends).
2394 The old API is now deprecated and should not be used anymore. This especially
2395 includes the following structure fields:
2396 - AVFormatContext.title
2397 - AVFormatContext.author
2398 - AVFormatContext.copyright
2399 - AVFormatContext.comment
2400 - AVFormatContext.album
2401 - AVFormatContext.year
2402 - AVFormatContext.track
2403 - AVFormatContext.genre
2406 - AVProgram.provider_name
