            Bug ID: 747297
           Summary: gl: live rpicamsrc/omxh264dec/glimagesink pipeline
                    fails
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
          Assignee: gstreamer-bugs at lists.freedesktop.org

     GNOME version: ---

This fails on my RPi:

gst-launch-1.0 rpicamsrc preview=0 fullscreen=0 ! queue ! h264parse !
omxh264dec ! glimagesink sync=false

On that pipeline we end up creating 3 GstGLBufferPools with unlimited buffer
size (max_buffers=0). At some point one of the pools errors out, fails to
create an EGLImage, likely because resources are exhausted.

It's a regression from 1.4.x. Perhaps we should limit max_buffers for the
EGL/RPI scenario, or use less buffer pools?
