These new functions take an AVPacket *pkt 2022 argument instead of a const uint8_t *buf / int buf_size pair. 2023 20242009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space() 2025 Introduce the av_fifo_space() function. 2026 20272009-04-02 - fabd246 - lavc 52.23.0 - AVPacket 2028 Move AVPacket declaration from libavformat/avformat.h to 2029 libavcodec/avcodec.h. 2030 20312009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats 2032 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR, 2033 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values. 2034 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and 2035 PIX_FMT_BGR32_1 are now macros. 2036 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases. 2037 Re-sort the enum PixelFormat list accordingly. 2038 This change breaks API/ABI backward compatibility. 2039 20402009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants 2041 Add the enum PixelFormat values: 2042 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE, 2043 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE. 2044 20452009-03-21 - ee6624e - lavu 50.0.0 - av_random* 2046 The Mersenne Twister PRNG implemented through the av_random* functions 2047 was removed.
