            Bug ID: 745473
           Summary: gl errors when using glcolorscale and gltransformation
    Classification: Platform
           Product: GStreamer
           Version: unspecified
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: xclaesse at gmail.com
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

With this pipeline:

gst-launch-1.0 uridecodebin uri=file:///something.jpg ! glcolorscale !
imagefreeze ! gltransformation ! glimagesink

It prints tones of error like this:

0:00:01.103329371  5979 0x7f129c0546d0 ERROR              glcontext
gstglcontext.c:1068:_gst_gl_debug_callback:<glcontextglx0> high: GL error from
API id:4, GL_INVALID_VALUE in glDeleteSync (not a valid sync object)

With gst-launch-1.0 it still work though. But with similar pipeline on my real
app it crash with this assert:

** (lt-scout-client:788): CRITICAL **: gst_video_frame_map_id: assertion
'info->finfo->format == meta->format' failed

Not sure that's related, but the error with gst-launch does not fill me with
confidence.
