Blocks: 584259
For a first pass, there's several things that would need to change:

- We use the K&R bracing style in our code { and } go on the same lines so elses are cuddled.
- We need to be careful with CoInitialize, we need a balancing CoUninitialize call and ordering matters there!
- The majority of the NvD3D specific code I'd like to see go into an NvD3DUtils.h/cpp file pair. And then we can call it for example like:

 if (mIs3DEnabled)
 {
   NvD3DUtils::LoadNv3DVStreaming();
 }

As far as I can see a 3DStreaming instance is device specific, so we may need to instantiate something for that. Or you might have a better idea?
- Local stack variables do not require any prefixes
Thanks for the comments, Bas. I'll go ahead and make the changes you suggested. Some comments below:

Where would you suggest I add the CoUninitialize()? The layer manager has an Initialize(), but I don't see a corresponding release\uninitialize.

I will go ahead and move all the code into a separate set of files and a new class, and then have an object of this class instantiated in the layer manager. Would that work for you?

The 3DStreaming instance is created once when the layer manager Initialize() function gets called. It will not re-create the dll instance if it already has been created by a prior Initialize() call. The 3DVSetDevice() function will accept a device pointer, so that ties the dll instance to some d3d device. Were you concerned about some specific case?

I think the destructor ought to work here.

We use a seperate LayerManager for each tab (which is its own window). Therefor we have to deal with multiple layer managers and multiple IDirect3DDevice9 objects. As as I could see none of the members are static - so each new LayerManager would, upon initialization re-create the DLL and tie it to a device, correct?

Yes, that is correct. Each new layer manager would (upon first time Init) create an instance of the DLL. Since the d3d9 device will be different from one tab to the next, we would need separate DLL instances to tie to the separate devices, right?

Yep, if your okay with that, that's fine!
I would just CoInitialize once in gfx startup and Uninitialize in gfx shutdown.  

Also, by "DLL instance" you just mean "in process COM server/object", right?  That is, we're just calling CoCreateInstance and letting it do whatever's needed under the hood, right?
(In reply to comment #7)
> I would just CoInitialize once in gfx startup and Uninitialize in gfx shutdown. 

Where would you recommend would be the best place to do this? I see gfxWindowsPlatform::gfxWindowsPlatform() and gfxWindowsPlatform::~gfxWindowsPlatform() as potential places where I could do the CoInitalize() and CoUninitialize() respectively, but not sure if that was what you had in mind.

Yes, we are calling CoCreateInstance to create a new instance of the COM object specified by our clsid, and letting it do whatever is needed under the hood. So yes, new instace of the COM object is a more accurate way to put it.

Yep, those would be fine -- the gfxWindowsPlatform singleton is created from our startup/shutdown routines, so the lifetime would be correct.

Though something to consider, now that I think about it; we should watch what happens to win32 startup time with this, to make sure that CoInitialize doesn't add any significant overhead.  (If it does we can just do it lazily, not a big deal.)

Patch to enable stereo rendering v2

Getting better! Trying to give some quick review feedback here!

In general, it seems I was unclear about our bracing style, although the } else { is now correct. The opening brace also goes on the same line, i.e.

if (foo) {
  dosomething();
} else {
  dosomethingelse();
}

A lot of the logging could probably also be done using NS_WARNING macro's (only in the case where we really don't expect things to fail! i.e. things that will fail for anyone with no 3D vision libraries installed can just use the logging you're using right now.

I'd like to see most of the code here go into the Nv3DUtils object and only 1 or 2 lines in here. Feel free to do console output in there and such.

These two are class members of the LayerManagerD3D9 and can go into the initializer list.

Is it possible to just release from the Nv3DVUtils object destructor? In any case this member should be an nsAutoPtr<Nv3DUtils>. Then we will not need any added destructor code as far as I'm concerned.

Checking just Nv3DVUtils here should be fine I think? It will be NULL is mIs3DEnabled, and even if it isn't it's fine if it gets initialized I suppose?

If no other error handling code is required I'm also okay with putting the log message in the Initialize function, and ignoring the return value here, I'm also fine with it returning void as long as it internally logs errors.

In this case too just checking mNv3DVUtils is probably fine?

m3DVStreaming can be an nsRefPtr<INV3DVStreaming> member, then you can use getter_AddRefs(m3DVStreaming) to pass it in, if this doesn't work for some reason, you can create an INV3DVStreaming * on the stack, assign that to m3DVStreaming and Release it right away. We generally prefer automatic pointers. All the calls to release should go away then, releasing can just be done by assigning NULL to m3DVStreaming.

I'd prefer a name a bit more verbose than Release, since it could be easily confused with a refcounting class. ReleaseResources perhaps?
Thanks for comments, Bas. 

For now, the license section in the 2 new files is still the same Mozilla one that is used in the other files (we still need to work out on our side what needs to go there). Other than that, I've updated the patch per your comments: I moved most of the logic into the Nv3DVUtils class, along with other changes that you suggested. 

Thanks.

I don't think this needs to be exported; it's only used in layers code (in that srcdir).

I'm not sure I fully understand the API, but I'm assuming that this is saying "when texture mYTexture is drawn to renderTarget, treat it as RIGHT_LEFT stereo"?  Do we need to do anything for the Cb/Cr textures, or is one texture having the stereo bit set sufficient to treat all of them in the same draw command as being stereo?

Looks fine otherwise, though!
Thanks for the comments, Vlad.

I was running into compilation issues with the header file not getting recognized by the layer manager header, hence I assumed it needed to be added to the exports. Is there some other way to make sure that the header file is visible to LayerManagerD3D9?

These calls in ImageLayerD3D9::RenderLayer() actually route everything to the Nv3DVUtils class, and most of the logic is handled there (the calls to the COM object are actually in the code in Nv3DVUtils). Regarding the API itself, the SetControl call specifies some information about the actual format of the stereo data. And as you mentioned, the SetMetadata call indicates that when the specified texture is rendered to the specified render target, we consider that to be a call with stereo data (of the format specified in the earlier SetControl call).

We don't need to consider the Cb and Cr data, as long as we are only dealing with 4:2:0 YUV data (that is, Cb and Cr are half the width and half the height of the luma). Do you envision this ever changing to the point where we might be dealing with 4:2:2 (Cb and Cr are same height as Y, but half the width) or 4:4:4 (Y, Cb, Cr are the same width and height) style data?

Thanks.

Oh, ha, this is because of the really funky (and broken, we never should have done this!) multi-dir and VPATH setup in gfx/layers.  Adding -I$(srcdir)/d3d9 to LOCAL_INCLUDES should do it, I think.

Oh right, forgot that this is 4:2:0.  I don't think we'll deal with 4:2:2 or 4:4:4 anytime soon as most things want to work with 4:2:0, so I wouldn't worry about that.

Makefile.in in gfx\layers does not have a LOCAL_INCLUDES. But, I'm assuming it is ok for me to add a new line for LOCAL_INCLUDES in this makefile, which is something like what I've put below, right?

LOCAL_INCLUDES = \
    -I$(srcdir)/d3d9/. \
    $(NULL)
Yep, exactly; don't even have to split it up on multiple lines (and probably don't include the /. -- it's probably fine but I'm terrified of weirdness).  Just 'LOCAL_INCLUDES = -I$(srcdir)/d3d9' should be fine.
Updated the patch to add LOCAL_INCLUDES in the Makefile.

I just asked Matthew, and Theora also supports 4:2:2 and 4:4:4. So possibly we need to add a check for that or something? I sadly haven't had time to examine rest of the patch yet.
Updating the html5 stereo rendering patch based on the re-arch done by Bas (to use a single device for all LayerManagers).

This destructor can go away, the nsAutoPtr template class destructor will be called on DeviceManagerD3D9 destruction which will also delete the pointer.

You could let the class destructor take care of destroying the m3DVStreaming object through the nsRefPtr destructor
Oh, we spoke about this patch briefly, the call to Initialize should probably be deferred to when it's first used, otherwise this could have startup performance impact for people not using 3D video.
Thanks for the comments. I'm in the process of making the updates.

If I set m3DVStreaming to NULL as above, wouldn't that cause the object to get destroyed through the nsRefPtr destructor? Or are you suggesting that I can just move all this code from Uninitialize() into the 3DVUtils destructor? (I wanted to have an UnInitialize() to make sure that it pairs up with the Initialize(), which is where the 3D Streaming COM object initialization happens)

Having Uninitialize is fine! If you set it to NULL here it will get released through the nsRefPtr assignment operator. When the nsRefPtr is destroyed at the end of the Nv3DVUtils destructor it will find no pointer and do nothing. You could not set it to NULL here though and just let the nsRefPtr destructor handle it. But it doesn't matter much!
