Most --enable-* flags used in the snap of FFmpeg are consistent with what's
used in the .deb of FFmpeg in Ubuntu. Determine which of the following are
generally useful and enable them:
--enable-ladspa--enable-libaom(core20)--enable-libjack--enable-libmysofa--enable-libvidstab(core20)--enable-lv2--enable-libiec61883(FTBFS on core18)--enable-frei0r
Add support for the Raspberry Pi in the armhf and arm64 builds.
[libraspberrypi-dev] will need including in the build process but doesn't need
to to be primed. This package adds the headers that make it possible to enable
--enable-mmal (Broadcom Multi-Media Abstraction Layer) and --enable-omx-rpi.
