Because we get the full uri (in this case `mymovie.avi?loop&noprogress`) via the poppler api and we can parse it as we like. In constrast, if you use the multimedia package, it will add a movie annotation (instead of a link annotation in the previous example) to the pdf. And with the glib API we can not get enought information from this movie annotation. With the QT bindings, you get much more, but we can not use something else than poppler-glib in pdfpc.
