"WebRenderLayer" is not a great name either given what RenderLayer is. I think this perhaps goes somewhere like PlatformCALayer (maybe not exactly there since it returns a raw layer) as a static method, and is called something like createPlatformLayerForHostingContext(LayerHostingContextID contextID)

Yes. I debugged the failures and found they are related to my implementation of MediaPlayerPrivateAVFoundationObjC::setSize(). I will remove MediaPlayerPrivateAVFoundationObjC::setSize(). The reasons are described in a comment below. >>> Source/WebCore/platform/graphics/cocoa/CreateWebRenderLayer.h:30 >>> +WEBCORE_EXPORT CALayer* CreateWebRenderLayer(uint32_t contextID); >> >> This file has a weird name; we don't usually make files to expose a single function.

I think this perhaps goes somewhere like PlatformCALayer (maybe not exactly there since it returns a raw layer) as a static method, and is called something like createPlatformLayerForHostingContext(LayerHostingContextID contextID) Good suggestions! I changed the function name to be createPlatformLayerForHostingContext() and put it in LayerHostingContext as a static function. >> Source/WebCore/platform/graphics/cocoa/WebCoreCALayerExtras.mm:91 >> +CALayer* CreateWebRenderLayer(uint32_t contextID) > > WebKit defines a LayerHostingContextID type, maybe we should type it? > Maybe we could use an ObjectIdentifier.

Is m_player losing this information somehow? When the setSize() function is called, the video layer might not be ready yet, so we need to save the size and use it when the video layer is ready. However, I realized that is not a good idea. The MediaPlayerPrivateAVFoundationObjc::setSize() is an empty function when the GPU Process is not enabled. We had better keep that behavior, so that we do not need to change the behavior of RenderVideo for the "media in GPU" feature. In addition, providing an empty setSize() function in MediaPlayerPrivateRemote can get rid of the meaningless XPC messages. In the new patch, the setSize() function in RemoteMediaPlayerProxy and also MediaPlayerPrivateAVFoundationObjC are removed. Also, the new patch implements RemoteMediaPlayerProxy::mediaPlayerContentBoxRect() to provide location and size information for the WebVideoContainerLayer when it creates a video layer. >> Source/WebKit/GPUProcess/media/RemoteMediaPlayerProxy.h:31 >> +#include "LayerHostingContext.h" > > We can probably forward declare LayerHostingContext instead.

Comment on attachment 387438 [details] Patch With this patch, the video element can render video, but the size and location information may be incorrect because the RenderVideo is not able to manage the sublayers of WebVideoContainerLayer through the WebVideoHostingLayer. This issue will be fixed in webkit.org/b/206132.

There is no encode() or decode() for LayoutRect, so I used LayoutPoint and LayoutSize() instead. I will implement the encode() and decode() for LayoutRect in the updated patch and use LayoutRect (pass by value) as the function parameter. >> Source/WebKit/GPUProcess/media/RemoteMediaPlayerManagerProxy.cpp:203 >> if (auto player = m_proxies.get(id)) > > It would be better to call completionHandler even if there is no player. > Maybe contextId should be an Optional<>? > > Maybe ASSERT(m_proxies.contains(id)); This is a good idea.
