How to slide the 6 picture of the skybox during runtime

I use the plugin(EasyMovieTexture) to convert the video(panoramagram) to a texture(Texture2D)

Now I need to change the panoramagram to the skybox during runtime

Is there any shader or plugin can help me solve the problem???

Maybe you just need call " skybox_renderer.material.SetTexture (“_SkyboxSide1”, VideoTextureSide1) ".
