Upload a CPU packed 24 RBG buffer to a 32 bit RGBA buffer on GPU

Hi, does there exist an example or documentation on what the best approach is to copy a 24 bit packed CPU buffer to a 32 bit RGBA buffer on the GPU. Is it a good option to use a compute shader for this ? Are there better approaches ? I want to do this for FHD resolution coming in at 6O Hz. Thanks Patrick.
