In this patch, we ask the media engine to return a handle for shareable dcomp surface, which will then be packaged into a new texture data type and being shared with the GPU process via the video bridge. DcompSurfaceImage is the image which contains the handle texture data, which doesn't support being accessed in the content process. When the compositor uploads the image to the GPU process, the corresponding texture host will be created. The render texture host will be created by that texture host, and it will be used in DCLayerTree. In DCLayerTree, we create a new type of surface for our dcomp handle. DCSurfaceHandle will ask the render texture host to reconstruct the surface by the handle shared from the remote process (the handle is actually duplicated to the parent process first due to the sandbox policy, and then be duplicated to the GPU process later) DCSurfaceHandle will attach that surface to its visual in order to display the video frame directly. In the whole process, it's not possible for Gecko to access any decoded video data which is protected by the media engine itself.
