291 'CodecID' identifier. Such code should either #undef CodecID or stop using the
292 CodecID name.
293
294 2012-08-03 - 239fdf1 - lavu 51.37.1 - cpu.h

352 For audio formats with fixed frame size, the last frame
353 no longer needs to be padded with silence, libavcodec

1314 Introduce the avfilter_next() function.
1315
1316 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1317 Change the signature of avfilter_register() to make it return an

1319
1320 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1321 Make the pixdesc.h API public.

1344
1345 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1346 Add a pts field to AVSubtitle which gives the subtitle packet pts
1347 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1348 not work right without this.
1349
1350 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1351 PKT_FLAG_KEY has been deprecated and will be dropped at the next

1353
1354 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1355 av_lockmgr_register() can be used to register a callback function
1356 that lavc (and in the future, libraries that depend on lavc) can use
1357 to implement mutexes. The application should provide a callback function
1358 that implements the AV_LOCK_* operations described in avcodec.h.
1359 When the lock manager is registered, FFmpeg is guaranteed to behave
1360 correctly in a multi-threaded application.
1361
1362 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1363 av_free_packet() is no longer an inline function. It is now exported.
1364
1365 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1366 Please use NULL instead. This has been supported since r16506
1367 (lavf > 52.23.1, lavc > 52.10.0).
1368
1369 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1370 The old decoding functions are deprecated, all new code should use the
1371 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1372 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1373 argument instead of a const uint8_t *buf / int buf_size pair.
1374
1375 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1376 Introduce the av_fifo_space() function.
1377
1378 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket

1380 libavcodec/avcodec.h.
1381
1382 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1383 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1384 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1385 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1386 PIX_FMT_BGR32_1 are now macros.
1387 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1388 Re-sort the enum PixelFormat list accordingly.
1389 This change breaks API/ABI backward compatibility.
1390
1391 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1392 Add the enum PixelFormat values:
1393 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1394 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1395
1396 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1397 The Mersenne Twister PRNG implemented through the av_random* functions
1398 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1399 instead.
1400
1401 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1402 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1403 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1404 and av_fifo_realloc2.
1405 In addition, the order of the function arguments of av_fifo_generic_read
1406 was changed to match av_fifo_generic_write.
1407 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1408 applications, they may not use sizeof() or directly access members.
1409
1410 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1411 Introduce a new metadata API (see av_metadata_get() and friends).
1412 The old API is now deprecated and should not be used anymore. This especially
1413 includes the following structure fields:
1414 - AVFormatContext.title
1415 - AVFormatContext.author
1416 - AVFormatContext.copyright
1417 - AVFormatContext.comment
1418 - AVFormatContext.album
1419 - AVFormatContext.year
1420 - AVFormatContext.track
1421 - AVFormatContext.genre
1422 - AVStream.language
1423 - AVStream.filename
1424 - AVProgram.provider_name
1425 - AVProgram.name
1426 - AVChapter.title
