[Interest] QtMultimedia how to crosscompile with GStreamer

[Denis Shienkov]

I'm sorry, the problem was on my side.. need to fix some of symlinks, like:

$ sudo ln -sf
/home/builder/Projects/tegra/rootfs/lib/arm-linux-gnueabihf/libglib-2.0.so.0
/home/builder/Projects/tegra/rootfs/usr/lib/arm-linux-gnueabihf/
libglib-2.0.so

BR,
Denis
