This is huge and we are looking forward to using it on our platform. As far as using is concerned... we have just compiled the most recent Qt 5.4 sources (including QtWebEngine) and sadly it does not work out-of-the-box. The websites render with black rectangles in place of images/divs. For example the following HTML:

renders with blue background body (this is ok) and black rectangle in place of the div (not ok). This happens on all the websites. Any tips on the possible cause of this behavior? Or where we can start debugging? Our QPA backend is EGLFS with OpenES 2.0.

We haven't tried very hard to get QtWebEngine or Chromium running on MIPS yet, if this is related to Skia you might have to dig a bit to find the cause. Personally I would start digging around ResourceProvider::TransferResource since this is where the texture ID is handed out to Qt through a mailbox, but the problem is probably very far from there. A RasterWorkerPool seems to be the one doing the previous step, and I assume that you could dump the produced tile pixels to a png on disk to see if already at this point your div is produced with the wrong color. It seems like they already ship the Chrome WebView on MIPS for Android, it might be worth looking at the configuration that they use there and try to match it as much as possible too.

I have compiled Qt5.4 framework successfully which does compile against the udev on my host. I think it is a failure in the qtwebengine to detect installed package. The problem is that I'm not to familiar with Gyp so it will take me some time to sort this out and have it compiled. Am I understanding you correctly by assuming the project can be built as it is provided by Qt5.4-beta ? or do I need to refer to Yocto in order to have it compiled for now ? As said there is no support for QtWebEngine with Yocto, and there won’t be with Qt 5.4, so it might or might not compile. You could try compiling the 1.0 branch from git, since there has been some OpenEmbedded fixes, which AFAIK did not make it into the beta and might fix your build, but there is no guarantee. /Andras ________________________________ From: Becsi Andras [Andras.Becsi at theqtcompany.com] Sent: Monday, October 27, 2014 11:41 AM To: Einar Már Björgvinsson Cc: qtwebengine at qt-project.org Subject: Re: [Qtwebengine] Cross-compiling qtwebengine for i.MX6Q Hi, On 27 Oct 2014, at 12:35 , Becsi Andras > wrote: Hi Einar, Cross-compiling QtWebEngine in Qt 5.4 is fully only supported with the Qt Enterprise Embedded SDK and platforms, so you will be on your own with vanilla yocto, which is on the roadmap for 5.5, as Jocelyn pointed out.

Yet at the same time I noticed some hints that it will be supported (e.g., the presence of the file ./third_party/WebKit/Source/platform/drm/ContentDecryptionModule.h) and know that it works already in Chrome. I also should note that I built the slightly-older 0.9 branch of qtwebengine because I am currently using Qt 5.3.

The integration and the Qt-side implementation is completely missing for this feature. The reason you found the mentioned header is that we only strip our snapshot from major unused modules that are well isolated, and where the removal does not hurt maintainability. /Andras
