Dear all, I would like to know what is the meaning of difference display layer type means?!
e.g. if a layer have the type 'DLTF_VIDEO', will such layer benfit anything if it use for render a video provider stream?!... I also found that a layer can still render a video provider stream if the layer only get type 'DLTF_GRAPHICS'. So, what is the difference for a layer get 'DLTF_VIDEO' and without it? BTW, could I write a directfb program such that it will render a video provider stream in layer 1 and then make the primary layer above the layer 1 and display some transparent GUI in primary layer? Since I found that I could do the same thing with primary layer only. e.g. render video and display the GUI both in the primary layer. So, any benefit if I use the 2 layer?! Thanks! Chris
