Just a wild guess - we usually test here with dmabuf capable devices and without X. As you are using gstglimagesink, the code around ext/gl/gstglimagesink.c (453) looks like gst_gl_context_create() went wrong. Does your GL work correctly? Maybe you can test the glimagesink with a simpler pipeline first. rsc <- being no gst expert -- Pengutronix e.K. | | Industrial Linux Solutions | http://www.pengutronix.de/ | Peiner Str. 6-8, 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 | -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
