            Bug ID: 763365
           Summary: glfilterapp not correctly drawing
    Classification: Platform
           Product: GStreamer
           Version: 1.6.3
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: nithibert at gmail.com
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

using glfilterapp (no callback just in the pipe) let show a flickering of a
first texture and some other black screen.
I try to patch it to only draw the texture, but it let display only black
screen.
Modifying filtercube (the more approaching plugins) using
gst_gl_filter_draw_texture give the same problems. It seems that as we do not
provide a shader, render is not correct. 

pipe used : 

gst-launch-1.0 videotestsrc ! glupload ! glconvert ! glfilterapp ! glimagesink
