I have been able to significantly enhance the quality of a video stream over UDP using multi-texturing in a slightly tweaked manner.
I am creating one texture for the video and then assigning it to 4 different samplers. On every sampler I am using Anisotropic filtering.
Somehow 4 has turned out to be the magic figure. Below 4, there is still some aliasing and gas in texts, and above 4 there is no significant change in video quality.
PFB the code snippet (Pardon my laziness, I am yet to put this in a loop) :
