What is the importance of SDL_TEXTUREACCESS_TARGET

SDL_Texture* SDL_CreateTexture(renderer, format, access, w, h)

access may be one of the following:

SDL_TEXTUREACCESS_STATIC
SDL_TEXTUREACCESS_STREAMING
SDL_TEXTUREACCESS_TARGET

Like in the wiki not so much description is given, but I really dont know which one will be better for displaying video, i have used SDL_TEXTUREACCESS_STREAMING(it looked convenient & also did a little wiki) , but I just want to know that If I use SDL_TEXTUREACCESS_TARGET will it increase the quality of my output video??

And also I will not be using SDL for game development, for the time being I am just want to achieve real time display from my usb camera.
