These new functions take an AVPacket *pkt 3598 argument instead of a const uint8_t *buf / int buf_size pair. 3599 36002009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space() 3601 Introduce the av_fifo_space() function. 3602 36032009-04-02 - fabd246 - lavc 52.23.0 - AVPacket 3604 Move AVPacket declaration from libavformat/avformat.h to 3605 libavcodec/avcodec.h. 3606 36072009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats 3608 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR, 3609 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values. 3610 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and 3611 PIX_FMT_BGR32_1 are now macros. 3612 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases. 3613 Re-sort the enum PixelFormat list accordingly. 3614 This change breaks API/ABI backward compatibility. 3615 36162009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants 3617 Add the enum PixelFormat values: 3618 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE, 3619 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE. 3620 36212009-03-21 - ee6624e - lavu 50.0.0 - av_random* 3622 The Mersenne Twister PRNG implemented through the av_random* functions 3623 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions 3624 instead. 3625 36262009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer 3627 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped 3628 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write 3629 and av_fifo_realloc2. 3630 In addition, the order of the function arguments of av_fifo_generic_read 3631 was changed to match av_fifo_generic_write. 3632 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by 3633 applications, they may not use sizeof() or directly access members. 3634 36352009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API 3636 Introduce a new metadata API (see av_metadata_get() and friends). 3637 The old API is now deprecated and should not be used anymore.
