How to incorporate qt-gstreamer into Qt?

Dear fellow coders,

i'm building Qt 5.7 sources to fit my embedded linux target device. My vendor-supplied SDK doesn't come with gstreamer. I've found some qt-gstreamer libraries online and would need some advice on how to incorporate qt-gstreamer into my Qt configure?

Do I cross-compile qt-gstreamer first using my cross-compiler? And how may I configure Qt configure to include gstreamer in my host Ubuntu PC?

Thanks!

You will also need GStreamer itself, not just the Qt bindings.

Also I am not sure if Qt needs the Qt bindings, I think QtMultimedia uses GStreamer directly. The Qt bindings are for application developers who want to use GStreamer themselves.

In general, yes, you will need to cross-compile GStreamer and make sure it is then part of the sysroot for compiling Qt and the target image for finding it at runtime.

so does it mean to say i'll first install gstreamer in Ubuntu, and then perform ./configure and add -gstreamer parameter?

Whether you install GStreamer for the host system is irrelevant.

actually i'm a little confused with sysroot, is it the filesystem of my target device itself?

sysroot is a directory that has the same content as the device.

That can be a local copy or the device remotely mounted.
