pipeline hangs when I use omxmjpegdec.

[TomMitchell]

Hello,

I am new to this forum (and also beginner in Linux + GStreamer
development.).
On a Raspberry pi 3 platform I last year installed GStreamer and I was able
to get my application running with omxmjpegdec.
Last week I started with new RPI with fresh install and got all the sources
via git. 
I was able to compile everything but my application doesn't show video.

Testing via gst-inspect-1.0 and debug macro I see the pipeline hangs:

When I replace the omxmjpegdec with the jpegdec the pipeline and application
works fine.

Is this a known problem or have I done something wrong ?
How can I (temporary) solve this problem ? 

Best regards,
Tom
