In pixfmt.h it mentions the following: "///< planar GBR 4:4:4 24bpp". Does this mean that each color value needs to be set to a 24-bit data type? Also, I'm still not clear about how to get the RGB data into the "uint8_t *src_data[4]" - how do I actually do this? >Note that all this has limited relevance for you if you >don't rescale yourself but use the scale filter (or >libswscale directly). Sorry, but I'm not sure what you mean. _______________________________________________ Libav-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/libav-user
