2301 registration and management of the registered filters.
2303 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
2304 Add a description field to AVFilter.
2306 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
2307 Change the interface of avfilter_make_format_list() from
2308 avfilter_make_format_list(int n, ...) to
2309 avfilter_make_format_list(enum PixelFormat *pix_fmts).
2311 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
2312 Make avfilter_get_video_buffer() recursive and add the w and h
2315 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
2316 Add w and h fields to AVFilterPic.
2318 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
2319 This is now an unsigned int instead of a signed int.
2321 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2322 Add a pts field to AVSubtitle which gives the subtitle packet pts
2323 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2324 not work right without this.
2326 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2327 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2328 major version. Use AV_PKT_FLAG_KEY instead.
2330 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2331 av_lockmgr_register() can be used to register a callback function
2332 that lavc (and in the future, libraries that depend on lavc) can use
2333 to implement mutexes. The application should provide a callback function
2334 that implements the AV_LOCK_* operations described in avcodec.h.
2335 When the lock manager is registered, FFmpeg is guaranteed to behave
2336 correctly in a multi-threaded application.
2338 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2339 av_free_packet() is no longer an inline function. It is now exported.
2341 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2342 Please use NULL instead. This has been supported since r16506
2343 (lavf > 52.23.1, lavc > 52.10.0).
2345 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2346 The old decoding functions are deprecated, all new code should use the
2347 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2348 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2349 argument instead of a const uint8_t *buf / int buf_size pair.
2351 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2352 Introduce the av_fifo_space() function.
2354 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2355 Move AVPacket declaration from libavformat/avformat.h to
2356 libavcodec/avcodec.h.
2358 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2359 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2360 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2361 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2362 PIX_FMT_BGR32_1 are now macros.
2363 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2364 Re-sort the enum PixelFormat list accordingly.
2365 This change breaks API/ABI backward compatibility.
2367 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2368 Add the enum PixelFormat values:
2369 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2370 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2372 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2373 The Mersenne Twister PRNG implemented through the av_random* functions
2374 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2377 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2378 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2379 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2380 and av_fifo_realloc2.
2381 In addition, the order of the function arguments of av_fifo_generic_read
2382 was changed to match av_fifo_generic_write.
2383 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2384 applications, they may not use sizeof() or directly access members.
2386 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2387 Introduce a new metadata API (see av_metadata_get() and friends).
2388 The old API is now deprecated and should not be used anymore. This especially
2389 includes the following structure fields:
2390 - AVFormatContext.title
2391 - AVFormatContext.author
2392 - AVFormatContext.copyright
2393 - AVFormatContext.comment
2394 - AVFormatContext.album
2395 - AVFormatContext.year
2396 - AVFormatContext.track
2397 - AVFormatContext.genre
2400 - AVProgram.provider_name
