2307 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2308 The old decoding functions are deprecated, all new code should use the
2309 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2310 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2311 argument instead of a const uint8_t *buf / int buf_size pair.
2313 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2314 Introduce the av_fifo_space() function.
2316 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2317 Move AVPacket declaration from libavformat/avformat.h to
2318 libavcodec/avcodec.h.
2320 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2321 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2322 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2323 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2324 PIX_FMT_BGR32_1 are now macros.
2325 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2326 Re-sort the enum PixelFormat list accordingly.
2327 This change breaks API/ABI backward compatibility.
2329 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2330 Add the enum PixelFormat values:
2331 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2332 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2334 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2335 The Mersenne Twister PRNG implemented through the av_random* functions
2336 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2339 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2340 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2341 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2342 and av_fifo_realloc2.
2343 In addition, the order of the function arguments of av_fifo_generic_read
2344 was changed to match av_fifo_generic_write.
2345 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2346 applications, they may not use sizeof() or directly access members.
2348 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2349 Introduce a new metadata API (see av_metadata_get() and friends).
2350 The old API is now deprecated and should not be used anymore. This especially
2351 includes the following structure fields:
2352 - AVFormatContext.title
2353 - AVFormatContext.author
2354 - AVFormatContext.copyright
2355 - AVFormatContext.comment
2356 - AVFormatContext.album
2357 - AVFormatContext.year
2358 - AVFormatContext.track
2359 - AVFormatContext.genre
2362 - AVProgram.provider_name
