2302 Introduce the av_fifo_space() function.
2304 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2305 Move AVPacket declaration from libavformat/avformat.h to
2306 libavcodec/avcodec.h.
2308 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2309 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2310 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2311 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2312 PIX_FMT_BGR32_1 are now macros.
2313 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2314 Re-sort the enum PixelFormat list accordingly.
2315 This change breaks API/ABI backward compatibility.
2317 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2318 Add the enum PixelFormat values:
2319 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2320 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2322 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2323 The Mersenne Twister PRNG implemented through the av_random* functions
2324 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2327 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2328 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2329 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2330 and av_fifo_realloc2.
2331 In addition, the order of the function arguments of av_fifo_generic_read
2332 was changed to match av_fifo_generic_write.
2333 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2334 applications, they may not use sizeof() or directly access members.
2336 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2337 Introduce a new metadata API (see av_metadata_get() and friends).
2338 The old API is now deprecated and should not be used anymore. This especially
2339 includes the following structure fields:
2340 - AVFormatContext.title
2341 - AVFormatContext.author
2342 - AVFormatContext.copyright
2343 - AVFormatContext.comment
2344 - AVFormatContext.album
2345 - AVFormatContext.year
2346 - AVFormatContext.track
2347 - AVFormatContext.genre
2350 - AVProgram.provider_name
