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: log: Pipeline is live and does not need PREROLL ... 0:00:01.159911519 781 0x20e5150 DEBUG omxvideodec gstomxvideodec.c:2454:gst_omx_video_dec_drain:<omxmjpegdec-omxmjpegdec0> Draining component 0:00:01.160094642 781 0x20e5150 DEBUG omxvideodec gstomxvideodec.c:2459:gst_omx_video_dec_drain:<omxmjpegdec-omxmjpegdec0> Component not started yet Got context from element 'autovideosink0': gst.gl.GLDisplay=context, gst.gl.GLDisplay=(GstGLDisplay)"\(GstGLDisplayEGL\)\ gldisplayegl0"; Setting pipeline to PLAYING ...

Is this a known problem or have I done something wrong ? How can I (temporary) solve this problem ? Best regards, Tom |
