commit 483530c1094f0ad6fe36663262b484be300f472e
Author: Yuri Wiitala <miu@chromium.org>
Date: Thu Feb 08 07:17:34 2018

Layer CopyOutputRequests execute in VIZ service.

Implements the final missing pieces allowing CopyOutputRequests made on
Layers to propagate and execute in the VIZ display compositor:

1. Added missing mojo fields and struct traits for viz::CopyOutputRequest
and viz::RenderPass.

2. Added extra transform code to cc::EffectTree::TakeCRsAndTransform()
to account for the scaling ratio, not just the source area.

3. Updated DelegatedFrameHost::CopyFromCompositingSurface() to use the
new scaling APIs, enabling testing and otherwise proving that all "the
plumbing" is in-place.

4. Updated RenderWidgetHostViewBrowserTests so that they now work with
--enabled-features=VizDisplayCompositor. (And, disabled dead tests I did
not feel we should bother updating; to be removed in a later change.)

5. Added privilege checks to make sure CopyOutputRequests cannot be made
from unprivileged clients. Added new RWHostImpl browser test to confirm.

Testing (all with and without --enable-features=VizDisplayCompositor):

1. All RenderWidgetHostViewBrowserTest content_browsertests pass.

2. On CrOS Ash desktop, tested CTRL-F5 (full screenshot) and
SHIFT-CTRL-F5 (partial screenshot).

3. On Linux, confirmed chrome.captureVisibleTab() screenshot API works
via the common/extensions/docs/examples/api/tabs/screenshot demo
extension.

cros: Workaround crash in Feedback tool under --mash

The feedback app uses desktop capture to take a screenshot, which
crashes in chrome --mash because it tries to use ash::Shell from the
browser process.

Just skip the screenshot under --mash. This allows users to send us
feedback reports, just missing the screenshot.

NativeDesktopMediaList: Use widget aura window instead of content window.

This changes the aura::Window instance being targeted for capture to the
window corresponding 1:1 with a compositor frame sink (the parent of the
content aura::Window). This is needed to support upcoming work to enable
browser window capture (all Aura platforms) and also desktop capture
(CrOS only) to use the VIZ service.

Even though the new target Window is being changed, the same pixels are
being captured by the existing desktop/browser window capture impl, and
so this change does not produce any user-visible behavior change.

Refactor many components of WCVCDBrowserTest for re-use.

Moves/Refactors a lot of test infrastructure that can be re-used in an
upcoming change to also test the new browser window capture impl:

ContentCaptureDeviceBrowserTestBase: A common base class that sets up a
content shell navigated to a test page, whose content can also be
changed as test procedures require.

FakeVideoCaptureStack: A simple representation of the entire downstream
video capture stack that just takes the screen-captured video frames an
stores them in a queue for later examination by the tests.

FrameTestUtil: Math/Color utilities for analyzing the content in the
captured video frames.

New Desktop/Browser Window screen capture impl, based on VIZ services.

Adds content::AuraWindowVideoCaptureDevice, which provides screen
capture of aura::Windows that have compositor frame sinks associated
with them. Then, for Chrome OS browser window capture, where a CFS is
not available, use a fall-back window capturer impl instead. The
intention is for the LameWindowCapturerChromeOS to be a temporary
solution until more work is complete on services/ui/ws (the new Window
Service).

Note: This change does not activate the new impl yet. A follow-up
change will switch from the legacy impl to the new impl.

Switch to the new VIZ-based Aura desktop/window capturer.

Changes content::InProcessVideoCaptureDeviceLauncher to use the new
viz::FrameSinkVideoCapturer-based implementation for the capture of Aura
windows. This provides desktop capture on ChromeOS, and window capture
on all Aura platforms (Win/ChromeOS/Linux).

The old implementation will be removed in a follow-up change.

Revert "Switch to the new VIZ-based Aura desktop/window capturer."

This reverts commit f18c4b374a237be908cae8125e5bb009dc3e7bfe.

Reason for revert: Need to do this to unbreak the build.

This CL depends on r559371, but r559755 reverted it. So this CL has to
be reverted as well. Filed  https://crbug.com/844264

commit 45ed65eaab60ab99686c7e9ea9a8b052bd85cd2c
Author: Yuri Wiitala <miu@chromium.org>

Reland: New Desktop/Browser Window screen capture impl + switch-over.

*** This is a reland of two prior changes. They are being relanded
together to avoid breaking the tree (compile) if only the first should
happen to need to be reverted. This reland includes a tweak to relax the
color accuracy requirements for the browser test when using software
compositing mode. Findings/Details on this are in the TODO code
comments, for later follow-up. ***

Change 1:
  https://chromium-review.googlesource.com/c/chromium/src/+/1006366

Adds content::AuraWindowVideoCaptureDevice, which provides screen
capture of aura::Windows that have compositor frame sinks associated
with them. Then, for Chrome OS browser window capture, where a CFS is
not available, use a fall-back window capturer impl instead. The
intention is for the LameWindowCapturerChromeOS to be a temporary
solution until more work is complete on services/ui/ws (the new Window
Service).

Change 2:
  https://chromium-review.googlesource.com/c/chromium/src/+/1060578

Switch to the new VIZ-based Aura desktop/window capturer.

Changes content::InProcessVideoCaptureDeviceLauncher to use the new
viz::FrameSinkVideoCapturer-based implementation for the capture of Aura
windows. This provides desktop capture on ChromeOS, and window capture
on all Aura platforms (Win/ChromeOS/Linux).

The old implementation will be removed in a follow-up change.

Remove now-dead code: AuraWindowCaptureMachine and DesktopCaptureDeviceAura

The new implementations have been live for a bit more than a milestone.
It's safe now to delete the old ones.

Merge media::ScreenCaptureDeviceCore into ScreenCaptureMachineAndroid.

With no other screen capture implementations dependent upon
media::ScreenCaptureDeviceCore, ThreadSafeCaptureOracle, etc.; this
change merges this code into ScreenCaptureMachineAndroid. Unused
functionality has been stripped-out, and minor callpoint- and lint-
related clean-ups were made. No behavior/functional changes.

Testing: Built monochrome_public_apk, installed it to my phone, and
confirmed Android screen capture from that Chromium build still works by
running a demo app: https://paulkinlan.github.io/screenrecord/.

'Place-holder' overlay rendering for CrOS window capture.

A minimal FrameSinkVideoCaptureOverlay implementation for browser window
video capture on ChromeOS (i.e., not desktop capture, and not
WebContents capture). The intention is for this code to be a temporary
solution until more work is complete on services/ui/ws (the new Window
Service).
