Dear community,
We are currently update our custom linux image by switching to linux 5.4-2. The goal is to have a distribution with Qt/QML + EGLFS + Gstreamer.
The first try is about to build a prototype image based on tdx-reference-minimal-image by tuning it as :
[local.conf]

The output build is:
ERROR: Task (/home/vincent/dvpt/oe-core/build/../layers/meta-toradex-nxp/backports/recipes-multimedia/gstreamer/gstreamer1.0-plugins-base_1.16.imx.bb:do_compile) failed with exit code '1'
Without qtmultimedia, the distribution is well compiled and we are able to launch Qt cinematic exemple on the board (Apalis imx6q 1.1b).
Please, advise
