235 'CodecID' identifier. Such code should either #undef CodecID or stop using the
236 CodecID name.
237
238 2012-08-03 - 239fdf1 - lavu 51.37.1 - cpu.h

296 For audio formats with fixed frame size, the last frame
297 no longer needs to be padded with silence, libavcodec
298 will handle this internally (effectively all encoders

1258 Introduce the avfilter_next() function.
1259
1260 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1261 Change the signature of avfilter_register() to make it return an

1265 Make the pixdesc.h API public.

1288
1289 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1290 Add a pts field to AVSubtitle which gives the subtitle packet pts
1291 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1292 not work right without this.
1293
1294 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1295 PKT_FLAG_KEY has been deprecated and will be dropped at the next

1297
1298 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1299 av_lockmgr_register() can be used to register a callback function
1300 that lavc (and in the future, libraries that depend on lavc) can use
1301 to implement mutexes. The application should provide a callback function
1302 that implements the AV_LOCK_* operations described in avcodec.h.
1303 When the lock manager is registered, FFmpeg is guaranteed to behave
1304 correctly in a multi-threaded application.
1305
1306 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1307 av_free_packet() is no longer an inline function. It is now exported.
1308
1309 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1310 Please use NULL instead. This has been supported since r16506
1311 (lavf > 52.23.1, lavc > 52.10.0).
1312
1313 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1314 The old decoding functions are deprecated, all new code should use the
1315 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1316 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1317 argument instead of a const uint8_t *buf / int buf_size pair.
1318
1319 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1320 Introduce the av_fifo_space() function.
1321
1322 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1323 Move AVPacket declaration from libavformat/avformat.h to
1324 libavcodec/avcodec.h.
1325
1326 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1327 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1328 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1329 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1330 PIX_FMT_BGR32_1 are now macros.
1331 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1332 Re-sort the enum PixelFormat list accordingly.
1333 This change breaks API/ABI backward compatibility.
1334
1335 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1336 Add the enum PixelFormat values:
1337 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1338 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1339
1340 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1341 The Mersenne Twister PRNG implemented through the av_random* functions
1342 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1343 instead.
1344
1345 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1346 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1347 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1348 and av_fifo_realloc2.
1349 In addition, the order of the function arguments of av_fifo_generic_read
1350 was changed to match av_fifo_generic_write.
1351 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1352 applications, they may not use sizeof() or directly access members.
1353
1354 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1355 Introduce a new metadata API (see av_metadata_get() and friends).
1356 The old API is now deprecated and should not be used anymore. This especially
1357 includes the following structure fields:
1358 - AVFormatContext.title
1359 - AVFormatContext.author
1360 - AVFormatContext.copyright
1361 - AVFormatContext.comment
1362 - AVFormatContext.album
1363 - AVFormatContext.year
1364 - AVFormatContext.track
1365 - AVFormatContext.genre
1366 - AVStream.language
1367 - AVStream.filename
1368 - AVProgram.provider_name
1369 - AVProgram.name
1370 - AVChapter.title
