opengl issue

[hrbaty]

Hello.

I'm facing a small problem, when creating a simple pipeline, using opengl plugin:

gst-launch-0.10 -v v4l2src ! videoscale ! glupload ! "video/x-raw-gl, width=640, height=480" ! glimagesink - this pipeline works fine, but when I combine it with i.e. glfiltersobel:

gst-launch-0.10 -v v4l2src ! videoscale ! glupload ! "video/x-raw-gl, width=640, height=480" ! glfiltersobel ! glimagesink

it dumps.

What am I missing here?

Thanks in advance!

Hi,

I think your graphic card or your driver is not supporting shaders.

Try setting GST_DEBUG=gldisplay:3 before gst-launch-0.10   to see the reasong.

You are free to add your example to this existing bug: https://bugzilla.gnome.org/show_bug.cgi?id=572767

Cheers
