132 To provide backwards compatibility, PixelFormat is now #defined as

358 e1d9dbf Add a new installed header - buffersrc.h
359 It contains a new function av_buffersrc_buffer() that allows passing
360 frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()
361 it allows for direct rendering.

1204 Change the signature of avfilter_register() to make it return an
1205 int. This is required since now the registration operation may fail.
1207 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1208 Make the pixdesc.h API public.

1232 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1233 Add a pts field to AVSubtitle which gives the subtitle packet pts
1234 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1235 not work right without this.
1237 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1238 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1239 major version. Use AV_PKT_FLAG_KEY instead.
1241 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1242 av_lockmgr_register() can be used to register a callback function
1243 that lavc (and in the future, libraries that depend on lavc) can use
1244 to implement mutexes. The application should provide a callback function
1245 that implements the AV_LOCK_* operations described in avcodec.h.
1246 When the lock manager is registered, FFmpeg is guaranteed to behave
1247 correctly in a multi-threaded application.
1249 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1250 av_free_packet() is no longer an inline function. It is now exported.
1252 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1253 Please use NULL instead. This has been supported since r16506
1254 (lavf > 52.23.1, lavc > 52.10.0).
1256 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1257 The old decoding functions are deprecated, all new code should use the
1258 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1259 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1260 argument instead of a const uint8_t *buf / int buf_size pair.
1262 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1263 Introduce the av_fifo_space() function.

1266 Move AVPacket declaration from libavformat/avformat.h to
1267 libavcodec/avcodec.h.
1269 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1270 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1271 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1272 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1273 PIX_FMT_BGR32_1 are now macros.
1274 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1275 Re-sort the enum PixelFormat list accordingly.
1276 This change breaks API/ABI backward compatibility.
1278 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1279 Add the enum PixelFormat values:
1280 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1281 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1283 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1284 The Mersenne Twister PRNG implemented through the av_random* functions
1285 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions

1289 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped

1292 In addition, the order of the function arguments of av_fifo_generic_read
1293 was changed to match av_fifo_generic_write.
