Thanks for the test. I overlooked that this was also used by metal.
Updated version attached and also available at
https://github.com/mkver/FFmpeg/tree/bin2c. Btw: The non-bin2c patches
are actually logically independent from the bin2c patches and don't need
to wait for them (there will be rebase conflicts when changing the
order, but fixing them would be on me).
The metal bits are untested, but should work.
I have not worked on the configure bits.
