f988ce6c
1347 av_lockmgr_register() can be used to register a callback function
1348 that lavc (and in the future, libraries that depend on lavc) can use
1349 to implement mutexes. The application should provide a callback function
227d1b98
DB
1350 that implements the AV_LOCK_* operations described in avcodec.h.
1351 When the lock manager is registered, FFmpeg is guaranteed to behave
1352 correctly in a multi-threaded application.

1362 The old decoding functions are deprecated, all new code should use the
1363 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1364 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1365 argument instead of a const uint8_t *buf / int buf_size pair.

1375 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1376 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1377 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1378 PIX_FMT_BGR32_1 are now macros.
1379 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.

1396 and av_fifo_realloc2.

227d1b98 1398 was changed to match av_fifo_generic_write.
