1299 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1300 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1301 PIX_FMT_BGR32_1 are now macros.
1302 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1303 Re-sort the enum PixelFormat list accordingly.
1304 This change breaks API/ABI backward compatibility.
1306 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1307 Add the enum PixelFormat values:
1308 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1309 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1311 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1312 The Mersenne Twister PRNG implemented through the av_random* functions
1313 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1316 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1317 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1318 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1319 and av_fifo_realloc2.
1320 In addition, the order of the function arguments of av_fifo_generic_read
1321 was changed to match av_fifo_generic_write.
1322 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1323 applications, they may not use sizeof() or directly access members.
1325 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1326 Introduce a new metadata API (see av_metadata_get() and friends).
1327 The old API is now deprecated and should not be used anymore. This especially
1328 includes the following structure fields:
1329 - AVFormatContext.title
1330 - AVFormatContext.author
1331 - AVFormatContext.copyright
1332 - AVFormatContext.comment
1333 - AVFormatContext.album
1334 - AVFormatContext.year
1335 - AVFormatContext.track
1336 - AVFormatContext.genre
1339 - AVProgram.provider_name
