You could use gstreamermm if Gst::TcpClientSrc[1] from gst-plugins-base
is added (which might not be that hard to do).  However, MP4 video
parsing[2] is part of the gst-plugins-bad GStreamer module and that is
not easily added at this time.  You'd have to use the plug-in
generically by creating it with Gst::ElementFactory::create_element()
(supplying the plug-in name for the factory name).

If there is a linux device associated with the webcam
(maybe /dev/video?) you should be able to use it as a source by using
Gst::FileSrc (opening it as a file), Gst::FdSrc (opening the device for
reading using file descriptors) or maybe Gst::GioSrc or
Gst::GioStreamSrc (using Giomm).
