1300 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1301 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1302 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1303 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1304 PIX_FMT_BGR32_1 are now macros.
1305 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1306 Re-sort the enum PixelFormat list accordingly.
1307 This change breaks API/ABI backward compatibility.
1309 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1310 Add the enum PixelFormat values:
1311 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1312 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1314 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1315 The Mersenne Twister PRNG implemented through the av_random* functions
1316 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1319 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1320 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1321 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1322 and av_fifo_realloc2.
1323 In addition, the order of the function arguments of av_fifo_generic_read
1324 was changed to match av_fifo_generic_write.
1325 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1326 applications, they may not use sizeof() or directly access members.
1328 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1329 Introduce a new metadata API (see av_metadata_get() and friends).
1330 The old API is now deprecated and should not be used anymore. This especially
1331 includes the following structure fields:
1332 - AVFormatContext.title
1333 - AVFormatContext.author
1334 - AVFormatContext.copyright
1335 - AVFormatContext.comment
1336 - AVFormatContext.album
1337 - AVFormatContext.year
1338 - AVFormatContext.track
1339 - AVFormatContext.genre
1342 - AVProgram.provider_name
