2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
2281
  Add a description field to AVFilter.
2282

2283
2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
2284 2285 2286 2287
  Change the interface of avfilter_make_format_list() from
  avfilter_make_format_list(int n, ...) to
  avfilter_make_format_list(enum PixelFormat *pix_fmts).

2288
2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
2289 2290 2291
  Make avfilter_get_video_buffer() recursive and add the w and h
  parameters to it.

2292
2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
2293
  Add w and h fields to AVFilterPic.
2294

2295
2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
2296 2297
  This is now an unsigned int instead of a signed int.

2298
2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2299 2300
  Add a pts field to AVSubtitle which gives the subtitle packet pts
  in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2301 2302
  not work right without this.

2303
2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2304
  PKT_FLAG_KEY has been deprecated and will be dropped at the next
2305 2306
  major version. Use AV_PKT_FLAG_KEY instead.

2307
2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2308 2309 2310
  av_lockmgr_register() can be used to register a callback function
  that lavc (and in the future, libraries that depend on lavc) can use
  to implement mutexes. The application should provide a callback function
2311 2312 2313
  that implements the AV_LOCK_* operations described in avcodec.h.
  When the lock manager is registered, FFmpeg is guaranteed to behave
  correctly in a multi-threaded application.
2314

2315
2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2316 2317
  av_free_packet() is no longer an inline function. It is now exported.

2318
2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2319 2320 2321
  Please use NULL instead. This has been supported since r16506
  (lavf > 52.23.1, lavc > 52.10.0).

2322
2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2323 2324 2325 2326 2327
  The old decoding functions are deprecated, all new code should use the
  new functions avcodec_decode_video2(), avcodec_decode_audio3() and
  avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
  argument instead of a const uint8_t *buf / int buf_size pair.

2328
2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2329 2330
  Introduce the av_fifo_space() function.

2331
2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2332 2333 2334
  Move AVPacket declaration from libavformat/avformat.h to
  libavcodec/avcodec.h.

2335
2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2336 2337 2338 2339 2340
  Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
  PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
  Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
  PIX_FMT_BGR32_1 are now macros.
  avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2341
  Re-sort the enum PixelFormat list accordingly.
2342 2343
  This change breaks API/ABI backward compatibility.

2344
2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2345 2346 2347 2348
  Add the enum PixelFormat values:
  PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
  PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

2349
2009-03-21 - ee6624e - lavu 50.0.0  - av_random*
2350 2351 2352 2353
  The Mersenne Twister PRNG implemented through the av_random* functions
  was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
  instead.

2354
2009-03-08 - 41dd680 - lavu 50.0.0  - AVFifoBuffer
2355 2356 2357 2358
  av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
  and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
  and av_fifo_realloc2.
  In addition, the order of the function arguments of av_fifo_generic_read
2359
  was changed to match av_fifo_generic_write.
2360 2361
  The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
  applications, they may not use sizeof() or directly access members.
2362

2363
2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2364 2365
  Introduce a new metadata API (see av_metadata_get() and friends).
  The old API is now deprecated and should not be used anymore. This especially
