2305 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2306 major version. Use AV_PKT_FLAG_KEY instead.
2308 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2309 av_lockmgr_register() can be used to register a callback function
2310 that lavc (and in the future, libraries that depend on lavc) can use
2311 to implement mutexes. The application should provide a callback function
2312 that implements the AV_LOCK_* operations described in avcodec.h.
2313 When the lock manager is registered, FFmpeg is guaranteed to behave
2314 correctly in a multi-threaded application.
2316 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2317 av_free_packet() is no longer an inline function. It is now exported.
2319 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2320 Please use NULL instead. This has been supported since r16506
2321 (lavf > 52.23.1, lavc > 52.10.0).
2323 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2324 The old decoding functions are deprecated, all new code should use the
2325 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2326 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2327 argument instead of a const uint8_t *buf / int buf_size pair.
2329 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2330 Introduce the av_fifo_space() function.
2332 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2333 Move AVPacket declaration from libavformat/avformat.h to
2334 libavcodec/avcodec.h.
2336 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2337 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2338 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2339 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2340 PIX_FMT_BGR32_1 are now macros.
2341 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2342 Re-sort the enum PixelFormat list accordingly.
2343 This change breaks API/ABI backward compatibility.
2345 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2346 Add the enum PixelFormat values:
2347 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2348 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2350 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2351 The Mersenne Twister PRNG implemented through the av_random* functions
2352 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2355 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2356 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2357 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2358 and av_fifo_realloc2.
2359 In addition, the order of the function arguments of av_fifo_generic_read
2360 was changed to match av_fifo_generic_write.
2361 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2362 applications, they may not use sizeof() or directly access members.
2364 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2365 Introduce a new metadata API (see av_metadata_get() and friends).
2366 The old API is now deprecated and should not be used anymore. This especially
2367 includes the following structure fields:
2368 - AVFormatContext.title
2369 - AVFormatContext.author
2370 - AVFormatContext.copyright
2371 - AVFormatContext.comment
2372 - AVFormatContext.album
2373 - AVFormatContext.year
2374 - AVFormatContext.track
2375 - AVFormatContext.genre
2378 - AVProgram.provider_name
