DescriptionMac Overlays: Enable h264 overlays
Punch a hole from GpuVideoDecodeAccelerator to VTVideoDecodeAccelerator
via a callback to BindImage, following the model found in
VaapiVideoDecodeAccelerator. If successful, set allow_overlay on the
frame's resource.

Did I miss something here, or was it actually that simple? https://codereview.chromium.org/1320893004/diff/1/ui/gl/gl_image_io_surface.mm File ui/gl/gl_image_io_surface.mm (right): https://codereview.chromium.org/1320893004/diff/1/ui/gl/gl_image_io_surface.m... ui/gl/gl_image_io_surface.mm:150: DCHECK(thread_checker_.CalledOnValidThread()); So, deleting DCHECKs never feels legit. I was hitting this in the stack descending from SetLevelImage -- that call was removing the last reference to the previously bound GLImage. Is there a particular need for ::Destroy to be called in this instance? The IOSurface can be unrefed from basically any context.

The IOSurface can be unrefed from basically any context. The image manager should keep track of all images and make sure Destroy is called before the image manager's context is destroyed. The DCHECK is here as a sanity check and could be removed if there's a good reason to why Destroy has not been called.
An alternative to the BindImage callback is to modify the TextureRef yourself, similar to ~line 380 here: https://codereview.chromium.org/1278733003/diff/1/content/common/gpu/media/an... I see that VAAPI does the same thing already, so I'm only recommending this if having the TextureRef makes things easier.

Thanks! Updated -- ptal. I merged texture_ids_ and picture_bindings_ (and the 2 new maps that I was about to add). This tracking makes calling Destroy() convenient. https://codereview.chromium.org/1320893004/diff/1/content/common/gpu/media/vt...

Why is the texture binding not enough? The reason for saving it is that there is a DCHECK that GLImageIOSurface will have Destroy called on it before it hits its destructor. The binding will result in the destructor being called at unpredictable times. My first thought was to remove the DCHECK, but reveman wanted to keep it in (see discussion in PS1).

Updated. I'm pretty sure that map thing doesn't work (this is where I get antsy that I don't actually understand anything in C++). https://codereview.chromium.org/1320893004/diff/20001/content/common/gpu/medi...

What exactly goes wrong? Oh -- it calls a copy constructor (at insert) -- scoped_ptr doesn't allow copy constructor. https://codereview.chromium.org/1320893004/diff/20001/content/common/gpu/medi... content/common/gpu/media/vt_video_decode_accelerator.cc:1054: picture_info->gl_image = gl_image; On 2015/09/04 01:37:49, sandersd wrote: > On 2015/09/04 01:31:30, ccameron wrote: > > On 2015/09/03 23:11:09, sandersd wrote: > > > Why does this need to be saved?

With the change to .reset(), you should be fine to switch to a regular scoped_ptr now. Better would be to have no pointers at all and use moves to get the PictureInfo into the map, but sadly we are not yet allowed to use C++11 library features to do that. If PictureInfo was itself copyable then that would be fine too, but the currently implementation means it would Destroy() the image immediately. This leaves two options: a) Remove the DCHECK and delete a bunch of code. b) Switch to scoped_ptr and mark PictureInfo as DISALLOW_COPY_AND_ASSIGN.

On l.1024 below, you definitely want to use the service id in the ScopedTextureBinder (which operates at the GL level and doesn't know about command buffers) On l.1051, below, you definitely want to use the client id in BindImage, which operates on command buffer structures. The code you currently have works, but because the 2 ids are inverted here, the code below that uses it looks really wrong...

Even with reset, scoped_ptr doesn't work -- operator[] can potentially instantiate the copy constructor. It looks like most people use ScopedPtrMap, so I switched to doing that (of note is that I do see some map<K, scoped_ptr<T>> instances in Windows-specific code). This may sound like a troll, but it is a serious (although perhaps dumb) question: In C++'s data structures, there is no specifying what interface a templated class must conform to -- it looks like std::map "wants" a copy constructor to be present, but nowhere is this formally specified. I would like it to be the case that std::map<T> would say "the following T-related functions must exist", and trying to instantiate a std::map<T> would fail with a meaningful error like "function F(const T&) doesn't exist", instead of the five pages of unparseable spew I currently get. Is there a name for this behavior? Vaguely reminds me of something about existential types from somewhere in my distant past. Is there any push to add such a feature to the language?

Yeah, I'd also like to do a rename on the "internal_texture v texture" vs "client_texture v service_texture" -- I'll wait until the frenetic M46 merging is done ...
