no - simply
the image you also linked to is of the original onda vx747 using ingenics chip (not rockchip) an that preview is available on there
but your players does not have this and can not get it at all, it has to be built into the firmware and if it were on your player then it would show it an not the files names
so no, no thumb previews on your player and no way to get that functionality
sorry
