Hello all, I'd like to convert the theora yuv_buffer to RGB that I can render onto a texture. Googling around, there are a tone of different formulae to do so. There is this (with lots of corrections and amendments further down the page): http://www.fourcc.org/fccyvrgb.php <http://www.fourcc.org/fccyvrgb.php> and there is the MSDN stuff that says you need to convert 4:2:0 and 4:2:2 to 4:4:4 first, before you do anything, and then it has it's own set of formulae here: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wceddraw/ht ml/_d...

Hello list, When I convert an yuv pixel into rgb using the recipies in http://www.fourcc.org/fccyvrgb.php I get an accurate color conversion but the contrast seems to be decreased. If i write, e.g., the pixel directly into an sdl yuv_overlay, I get a well-contrasted frame, however, if I convert the pixel to rgb and call SDL_MapRGB, I get a contrast-decreased frame. Thanks, Ribamar

...re these strides? what exactly is a "plane" in a frame, and what does it do? what i want to achieve is getting the Y, U and V data for each single pixel, so i can convert it to one R, G and B value. i am trying to apply one of the conversion formulas presented at http://www.fourcc.org/fccyvrgb.php, but as of now was never successful since the description of the buffer format doesn't help me getting the idea.... i would really be very thankful if someone could help me with this :) regards, ---david

Hi all, how can I convert a RGB (24 or 32) image I'm getting from a webcam for example to YUV to compress it with theora, decompress it and convert it back to RGB to draw it? Any suggestions? Best regards, Florian (Stuttgart, GERMANY)

hi folks! i would like to know whether there will be some function to decode to some plain 24 bit RGB buffer in the future. i think this feature is sometimes important, especially when using different surface layers, or when modifying the buffer in realtime. if this feature will definitely not be, could someone tell me how i can convert to some RGB buffer in realtime? i already tried different
