Problems with ofBaseVideoplayer as base class

Hi Arturo.

I'm working with Pelayo on this.

We couldnt use the add-on as ofBaseVideoplayer. Changed that.

Now we draw with ofTexture object the pixels. (is it fastest way?)

We also found some weird behaviour in of clamp finding current frame.

Its a bit strange how pixel queue is handle. We commented it a bit hopping to improve it.

Thanks!
