I needs to have the fastest RGB 24 bits data streaming to texture (movie). It seems that PBO with RGB24 is slow, however my data are 24 bits .. I don't wants to use CPU to translate from RGB24 to RGB32. Is it possible to use Texture Buffer Object, to copy RGB24 as RGB32 and repack correctly in a shader to 24 bits ? Will it be efficient as pho ? Is there a limitation to use TBO ?
