1301 (lavf > 52.23.1, lavc > 52.10.0).
1303 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1304 The old decoding functions are deprecated, all new code should use the
1305 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1306 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1307 argument instead of a const uint8_t *buf / int buf_size pair.
1309 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1310 Introduce the av_fifo_space() function.
1312 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1313 Move AVPacket declaration from libavformat/avformat.h to
1314 libavcodec/avcodec.h.
1316 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1317 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1318 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1319 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1320 PIX_FMT_BGR32_1 are now macros.
1321 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1322 Re-sort the enum PixelFormat list accordingly.
1323 This change breaks API/ABI backward compatibility.
1325 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1326 Add the enum PixelFormat values:
1327 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1328 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1330 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1331 The Mersenne Twister PRNG implemented through the av_random* functions
1332 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1335 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1336 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1337 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1338 and av_fifo_realloc2.
1339 In addition, the order of the function arguments of av_fifo_generic_read
1340 was changed to match av_fifo_generic_write.
1341 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1342 applications, they may not use sizeof() or directly access members.
1344 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1345 Introduce a new metadata API (see av_metadata_get() and friends).
1346 The old API is now deprecated and should not be used anymore. This especially
1347 includes the following structure fields:
1348 - AVFormatContext.title
1349 - AVFormatContext.author
1350 - AVFormatContext.copyright
1351 - AVFormatContext.comment
1352 - AVFormatContext.album
1353 - AVFormatContext.year
1354 - AVFormatContext.track
1355 - AVFormatContext.genre
1358 - AVProgram.provider_name
