Hi,

I have solved this problem, this is my local.conf file:

You need to add qtmultimedia submodule.
Here is a document regarding to qtmultimedia usage:

Have a great day,

Hi Victor,

     Thank you for you reply.

     qtmultimedia has been added already in yocto, we don't need to add. look at this:

[fulinux@dev-ubuntu fsl-release-bsp]$ cat sources/meta-qt5/recipes-qt/qt5/qtmultimedia_git.bb    
require qt5.inc
require qt5-git.inc
