I can never seem to get past the initial C compiler test. configure -prefix/usr -localstatedir/var. mkdir /tmp/build rm -rf /tmp/build/ tar -xvzf libomxil-bellagio-0.9.3.tar.gz tar -xf libomxil-bellagio0.9. cd libomxil-bellagio-0.9.3. ![]() Here's how to compile and make a Slackware package. 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. In order to use the RPi's hardware video acceleration, you need the OpenMAX libs. unfortunately ffmpeg do not build with opencv. I've Googled extensively today, installing/compiling various things. Im planning to use Opencv(3.4) in C++ (Qt creator) in Raspberry pi 3. 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 Adapt the build system to build ffmpeg with the required encoder (I would need to add the flags -enable-gpl -enable-omx -enable-omx-rpi -enable-nonfree). 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. ![]()
