These new functions take an AVPacket *pkt 3319 argument instead of a const uint8_t *buf / int buf_size pair. 3320 33212009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space() 3322 Introduce the av_fifo_space() function. 3323 33242009-04-02 - fabd246 - lavc 52.23.0 - AVPacket 3325 Move AVPacket declaration from libavformat/avformat.h to 3326 libavcodec/avcodec.h. 3327 33282009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats 3329 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR, 3330 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values. 3331 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and 3332 PIX_FMT_BGR32_1 are now macros. 3333 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases. 3334 Re-sort the enum PixelFormat list accordingly. 3335 This change breaks API/ABI backward compatibility. 3336 33372009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants 3338 Add the enum PixelFormat values: 3339 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE, 3340 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE. 3341 33422009-03-21 - ee6624e - lavu 50.0.0 - av_random* 3343 The Mersenne Twister PRNG implemented through the av_random* functions 3344 was removed.
