Is there any further debugging tips I could use to find why it isn't producing output? Any common mistakes? What component should I look at for more information about this? Any more info I could provide to help debugging? The omx initialization done by omx_h264dec shows no issues, only one assertion from ti-syslink, but it keeps moving on and it seems to get to the Running status clearly. I never see FillBufferDone get called for the output port, so the pipeline stalls. On the other side, the output loop pushes buffers to the output port using 'FillThisBuffer'. The buffers are pushed into the omx input port and this part returns ErrorNone. A closer look at gstreamer and omx logs shows that omx_h264dec is receiving buffers from upstream elements and negotiates properly. Gst-launch filesrc location=test.mov ! qtdemux ! h264parse ! omx_h264dec ! fakesinkįakesink never receives any buffers. it fails with errors such as gcc: error: missing argument to '-mcpu='.Īnyone got any thoughts.I'm trying to get decoding of h264 streams with gstreamer using TI's omx elements. I can never seem to get past the initial C compiler test. I've tried installing libomxil-bellagio-dev and libomxil-bellagio-bin as well as numerous guides for compiling ffmpeg on RPi all to no avail. I've Googled extensively today, installing/compiling various things. libOmxCore.so not foundĮrror initializing output stream 0:0 - Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height Essentially I'm trying to livestream one of my cameras to Youtube, which was working well previously on Raspbian.įfmpeg -nostdin -r 14.5 -i -f lavfi -i anullsrc -b:v 2M -b:a 128k -c:v h264_omx -ar 22050 -f flv rtmp://a./live2/ I've got one remaining hurdle for the moment: using the h264_omx hardware encoder with ffmpeg (currently does work with the h264 software encoder). I'm nearly finished migrating my RPi4 4GB to Ubuntu 19.10 with Gnome - it is running better than I thought it would.
