1301 The old decoding functions are deprecated, all new code should use the
1302 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1303 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1304 argument instead of a const uint8_t *buf / int buf_size pair.
1306 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1307 Introduce the av_fifo_space() function.
1309 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1310 Move AVPacket declaration from libavformat/avformat.h to
1311 libavcodec/avcodec.h.
1313 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1314 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1315 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1316 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1317 PIX_FMT_BGR32_1 are now macros.
1318 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1319 Re-sort the enum PixelFormat list accordingly.
1320 This change breaks API/ABI backward compatibility.
1322 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1323 Add the enum PixelFormat values:
1324 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1325 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1327 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1328 The Mersenne Twister PRNG implemented through the av_random* functions
1329 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1332 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1333 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1334 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1335 and av_fifo_realloc2.
1336 In addition, the order of the function arguments of av_fifo_generic_read
1337 was changed to match av_fifo_generic_write.
1338 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1339 applications, they may not use sizeof() or directly access members.
1341 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1342 Introduce a new metadata API (see av_metadata_get() and friends).
1343 The old API is now deprecated and should not be used anymore. This especially
1344 includes the following structure fields:
1345 - AVFormatContext.title
1346 - AVFormatContext.author
1347 - AVFormatContext.copyright
1348 - AVFormatContext.comment
1349 - AVFormatContext.album
1350 - AVFormatContext.year
1351 - AVFormatContext.track
1352 - AVFormatContext.genre
1355 - AVProgram.provider_name
