            Bug ID: 746399
           Summary: glupload: Pretends to support all memory and video
                    formats
    Classification: Platform
           Product: GStreamer
           Version: 2.x
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
          Assignee: gstreamer-bugs at lists.freedesktop.org

     GNOME version: ---

The glupload element sets it's caps to video/x-raw(ANY). This is very wrong,
the uploader needs to be aware of the memory type (sysmem, DMABUF, EGL) in
order to perform the upload or texture mapping. Finally, it can only upload
from sysmem of format it knows about. Here's an example showing how badly this
fails:

gst-launch-1.0 videotestsrc ! video/x-raw,format=NV12_64Z32 ! glupload !
