           Summary: videomixer can't compile orc program
    Classification: Platform
           Product: GStreamer
           Version: 0.11.x
        OS/Version: Windows
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.freedesktop.org

     GNOME version: ---


This problem was seen on a MinGW build of RELEASE-0.11.94.  It could be Windows
specific:

The problem occurs when background=transparent and the video has an alpha
component.

Pipeline:

run videomixer name=mix  background=transparent   ! videoconvert !
autovideosink  videotestsrc ! video/x-raw,format=RGBA,
width=200,height=200,framerate=10/1  ! videoconvert ! mix.sink_1  videotestsrc
pattern=smpte ! video/x-raw,format=RGBA, width=720,height=480,framerate=10/1  !
videoconvert ! mix.sink_0

Debug Trace:

There are two issues:

1.  The orc compile failed.
2.  The error was not detected and the backup function was not called.

I'm using orc-0.4.16, which I built using the instructions on the GStreamer
wiki.

Other orc programs compile and run properly.
