|
585 |
2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register() |
586 |
av_lockmgr_register() can be used to register a callback function |
587 |
that lavc (and in the future, libraries that depend on lavc) can use |
588 |
to implement mutexes. The application should provide a callback function |
589 |
that implements the AV_LOCK_* operations described in avcodec.h. |
590 |
When the lock manager is registered, FFmpeg is guaranteed to behave |
591 |
correctly in a multi-threaded application. |
592 |
|
593 |
2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet() |

599 |
|
600 |
2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle |
601 |
The old decoding functions are deprecated, all new code should use the |
602 |
new functions avcodec_decode_video2(), avcodec_decode_audio3() and |
603 |
avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt |
604 |
argument instead of a const uint8_t *buf / int buf_size pair. |
605 |
|
606 |
2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space() |

612 |
|
613 |
2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats |
614 |
Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR, |
615 |
PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values. |
616 |
Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and |
617 |
PIX_FMT_BGR32_1 are now macros. |
618 |
avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases. |
619 |
Re-sort the enum PixelFormat list accordingly. |
620 |
This change breaks API/ABI backward compatibility. |
621 |
|
622 |
2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants |
623 |
Add the enum PixelFormat values: |
624 |
PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE, |
625 |
PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE. |
626 |
|
627 |

628 |
The Mersenne Twister PRNG implemented through the av_random* functions |
629 |
was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions |
630 |
instead. |
631 |
|
632 |
2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer |
633 |
av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped |
634 |
and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write |
635 |
and av_fifo_realloc2. |
636 |
In addition, the order of the function arguments of av_fifo_generic_read |
637 |
was changed to match av_fifo_generic_write. |
638 |
The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by |
639 |
applications, they may not use sizeof() or directly access members. |
640 |
|
641 |
2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API |
642 |
Introduce a new metadata API (see av_metadata_get() and friends). |
