I'm able to navigate to youtube.com. But, once I click on a video, the app is being crashed.

How did you install libcrypto ?

surendraece08

I've not explicitly installed libcrypto but with the help of bitbake-ing meta-elf layer, I guess the library is available.

SGaist

Do you mean you added it later rather than as part of the image you built for Qt ?

surendraece08

@SGaist Yes! I've added the it as a separate package as shown below.
Integrating QTWebEngine to the image:

Just add the following lines of code to conf/local.conf QTWebEngine for integration.

IMAGE_INSTALL_append = "
qtwebengine-dev
qtwebengine
"

Also add the following code in sources/meta-qt5/recipes-qt/packagegroups/packagegroup-qt5-toolchain-target.bb
USE_WEBENGINE = "
qtwebengine-dev
qtwebengine-mkspecs
qtwebengine
"

RDEPENDS_${PN} += "
${USE_WEBENGINE}
"
If you want WebEngine examples in the image, add the following code in conf/local.conf

IMAGE_INSTALL_append = " qtwebengine-examples
qtbase-fonts-ttf-vera
qtbase-fonts-ttf-dejavu
qtbase-fonts-pfa
qtbase-fonts-pfb
qtbase-fonts-qpf"

@SGaist Sorry for the late reply, as I was out to town. Please help me with this. The issue is still on the same status.

SGaist

Are you on the latest 5.6 version ?

On a side note, 5.9 is the new LTS.
