Fixes the following error:
Check failed: !pending_frame_callback_. Got overlapping IssueExternalBeginFrame
To test:
Run `cefclient --off-screen-rendering-enabled --external-begin-frame-enabled`
on Windows without crashing.
The Chrome browser can now be hosted in a Views-based application on Mac
(see issue #2969).
To launch a fully-featured Chrome window using cefsimple:
$ open cefsimple.app --args --enable-chrome-runtime
To launch a minimally-styled Views-hosted window using cefsimple:
$ open cefsimple.app --args --use-views [--enable-chrome-runtime]
To launch a fully-styled Views-hosted window using cefclient:
$ open cefclient.app --args --use-views [--enable-chrome-runtime]
Known issues:
- Some Views unit tests are currently failing on Mac.
The cursor change can now be handled by the client with both windowed and
off-screen rendering.
Returning true from OnCursorChange will disable the default cursor change
behavior. This is functionally equivalent to the
CefBrowserHost::SetMouseCursorChangeDisabled method, so that method has been
removed.
- CefURLRequest::Create is no longer supported in the renderer process
(see https://crbug.com/891872). Use CefFrame::CreateURLRequest instead.
- Mac platform definitions have been changed from `MACOSX` to `MAC`
(see https://crbug.com/1105907) and related CMake macro names have
been updated. The old `OS_MACOSX` define is still set in code and CMake
for backwards compatibility.
- Linux ARM build is currently broken (see https://crbug.com/1123214).
- Windows: 10.0.19041 SDK is now required.
- macOS: 10.15.1 SDK (at least Xcode 11.2) is now required.
- Remove CefMediaSource::IsValid and CefMediaSink::IsValid which would
always return true.
This includes the following changes:
- Update usage of surface IDs to match the Aura implementation from the
RWHVAura/Window classes.
- Batch CefBrowserHost::WasResized calls to avoid excessive/unnecessary calls
to SynchronizeVisualProperties.
- Cache the results of CefRenderHandler::GetViewRect after resize and make
RWHVOSR::GetViewBounds the source of truth for all size calculations.
- Fix bounds calculations in CefVideoConsumerOSR with GPU enabled.
Known issues:
- The size passed to OnPaint may be off by 1 pixel in cases where the device
scale factor is not 1 and does not divide evenly into the pixel size. This is
due to the inexact conversion from integer pixel size to integer logical size
for GetViewRect.
Ozone builds can run with different platform backends (Wayland, X11, etc). Usage of the Views framework is required, and the cefclient sample application is not supported.
Example usage:
$ export GN_DEFINES="use_ozone=true"
$ cd /path/to/chromium/src/cef
$ ./cef_create_projects.sh
$ cd /path/to/chromium/src
$ ninja -C out/Release_GN_x64 cefsimple
$ ./out/Release_GN_x64/cefsimple --use-views --ozone-platform=wayland
Binary distributions can be created by passing the `--ozone` flag to make_distrib.py.
- Windows: 10.0.17763.0 SDK is now required.
- Mac: 10.13 SDK is now required.
- Removed CefRequestContext::ResolveHostCached which is no longer supported by Chromium.
- The |category| value for all TRACE calls from CEF client applications is now
"cef.client" due to https://crrev.com/331266377d.
- The |with_menu_marker| parameter to CreateMenuButton has been removed due to
https://crrev.com/7f7e382118.
- Add CefWindowInfo::shared_texture_enabled and
CefRenderHandler::OnAcceleratedPaint for shared texture support. Currently
only supported on Windows (D3D11).
- Add CefWindowInfo::external_begin_frame_enabled and
CefBrowserHost::SendExternalBeginFrame for external begin frame support.
Known issues:
- The CefLoadCRLSetsFile function needs to be re-implemented (see issue #2497).
- Linux: GTK2 support has been removed. The cefclient sample needs to be updated
to use GTK3 (see issue #2014).
