// The video layers are composited on the webkit thread and then copied over
// to the UI thread with the same ID. For rendering, we are only using the
// video layers on the UI thread. Therefore, on the UI thread, we have to use
// the videoLayerId from Java side to find the exact video layer in the tree
// to set the surface texture.
// Every time a play call into Java side, the videoLayerId will be sent and
// saved in Java side. Then every time setBaseLayer call, the saved
// videoLayerId will be passed to this function to find the Video Layer.
// Return value: true when the video layer is found.
