pdfpc supports its own particular method of inserting media into presentations (see an example by downloading https://github.com/pdfpc/pdfpc/releases/latest/download/pdfpc-video-example.zip). When such files are viewed in pdfpc, pdfpc uses gstreamer to create a gtksink and a cairooverlay (see https://github.com/pdfpc/pdfpc/blob/master/src/classes/action/movie.vala lines 682 and 800). These are found in media-plugins/gst-plugins-gtk and media-plugins/gst-plugins-cairo respectively. Without them, pdfpc will still run, but won't show videos. It will print error messages in a terminal if one is attached, but otherwise the error is silent. I assume that the gstreamer USE flag is meant for enabling this feature, but it's missing these as RDEPENDS. Note that they are not required for building, just at runtime. The specific plugins have also changed in recent years, so it may be that in the past, gst-plugins-base was sufficient. If the gstreamer USE flag has some other intention for pdfpc, then maybe another USE flag is required.
Hi William, you're right, fix is queued - thanks alot for your detailed report!
