Hi, thanks for putting this together! I tried running the following script on my RPI3 B+, Jessie but I'm getting error

git clone https://github.com/FFmpeg/FFmpeg.git cd FFmpeg sudo ./configure --arch=armel --target-os=linux --enable-gpl --enable-omx --enable-omx-rpi --enable-nonfree

ERROR `pi@raspberrypi:~ $ cd /home/pi/

Fixed it, it was a network issue on the RPI3 part. But now I get this error

pi@raspberrypi:~ $ cd FFmpeg
pi@raspberrypi:~/FFmpeg $ sudo ./configure --arch=armel --target-os=linux --enable-gpl --enable-omx --enable-omx-rpi --enable-nonfree

ERROR: OMX_Core.h header not found

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.

I have the exact same problem installing on Stretch on RPi 3. Worked great before on Jessie..

Just found the solution. Run the following before configure.

sudo apt-get install libomxil-bellagio-dev
