Gstreamer mit gst-omx Raspberry Pi

Den ich kompiliert habe, die mit gstreamer gst-omx nach diesem tutorial: http://www.onepitwopi.com/raspberry-pi/gstreamer-1-2-on-the-raspberry-pi/

Alles ging gut und am Ende, wenn ich lief gst-inspect-1.0 | grep omx ich habe:

omx:  omxmpeg2videodec: OpenMAX MPEG2 Video Decoder
omx:  omxmpeg4videodec: OpenMAX MPEG4 Video Decoder
omx:  omxh263dec: OpenMAX H.263 Video Decoder
omx:  omxh264dec: OpenMAX H.264 Video Decoder
omx:  omxtheoradec: OpenMAX Theora Video Decoder
omx:  omxvp8dec: OpenMAX VP8 Video Decoder
omx:  omxmjpegdec: OpenMAX MJPEG Video Decoder
omx:  omxvc1dec: OpenMAX WMV Video Decoder
omx:  omxh264enc: OpenMAX H.264 Video Encoder
omx:  omxanalogaudiosink: OpenMAX Analog Audio Sink
omx:  omxhdmiaudiosink: OpenMAX HDMI Audio Sink

Alles scheint in Ordnung aber wenn ich versuche, mit gst-launch-1.0, mit der omx-decoder bekomme ich nichts.

Diese pipeline läuft wunderbar(aber wirklich langsam, so dass ich Sie geschlossen in der Mitte):

pi@raspberrypi ~ $ gst-launch-1.0 filesrc location=./h264_720p_hp_5.1_6mbps_ac3_planet.mp4 ! qtdemux ! h264parse ! avdec_h264 ! eglglessink

Dann versuche ich die gleiche pipeline mit omx ich dieses:

Ich denke, dies ist der wichtigste Teil dieser Fehler:

ERROR: from element /GstPipeline:pipeline0/GstOMXH264Dec-omxh264dec:omxh264dec-omxh264dec0: Could not configure supporting library.

aber konnte nicht finden jede Bezugnahme auf diese Fehler...

Versucht zu machen, überprüfen Sie die gst-omx aber es muss nicht alle check-routine.

Kann jemand etwas Licht in diese Sache?

Vielen Dank!
=D

UPDATE:

Seltsam, wenn ich anfing, mein rpi, ohne das hdmi-Kabel und ausgeführt meine pipeline via ssh funktionierte es(aber ich sehe keine Bild, weil Sie das hdmi-Kabel war aus)

Bedeutet dies, dass das problem in der eglglessink?
