2305 When the lock manager is registered, FFmpeg is guaranteed to behave
2306 correctly in a multi-threaded application.
2308 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2309 av_free_packet() is no longer an inline function. It is now exported.
2311 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2312 Please use NULL instead. This has been supported since r16506
2313 (lavf > 52.23.1, lavc > 52.10.0).
2315 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2316 The old decoding functions are deprecated, all new code should use the
2317 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2318 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2319 argument instead of a const uint8_t *buf / int buf_size pair.
2321 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2322 Introduce the av_fifo_space() function.
2324 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2325 Move AVPacket declaration from libavformat/avformat.h to
2326 libavcodec/avcodec.h.
2328 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2329 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2330 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2331 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2332 PIX_FMT_BGR32_1 are now macros.
2333 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2334 Re-sort the enum PixelFormat list accordingly.
2335 This change breaks API/ABI backward compatibility.
2337 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2338 Add the enum PixelFormat values:
2339 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2340 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2342 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2343 The Mersenne Twister PRNG implemented through the av_random* functions
2344 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2347 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2348 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2349 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2350 and av_fifo_realloc2.
2351 In addition, the order of the function arguments of av_fifo_generic_read
2352 was changed to match av_fifo_generic_write.
2353 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2354 applications, they may not use sizeof() or directly access members.
2356 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2357 Introduce a new metadata API (see av_metadata_get() and friends).
2358 The old API is now deprecated and should not be used anymore. This especially
2359 includes the following structure fields:
2360 - AVFormatContext.title
2361 - AVFormatContext.author
2362 - AVFormatContext.copyright
2363 - AVFormatContext.comment
2364 - AVFormatContext.album
2365 - AVFormatContext.year
2366 - AVFormatContext.track
2367 - AVFormatContext.genre
2370 - AVProgram.provider_name
