Is it possible to use h264ify with Facebook?

[DAC324]

Hello,

Facebook, as of now, also delivers videos in VP9 format instead of H.264, similar to YouTube: [{"alpha mode":"is_opaque","codec":"vp9","coded size":"1280x720","color space":"{primaries:BT709, transfer:BT709, matrix:BT709, range:LIMITED}","encryption scheme":"Unencrypted","has extra data":true,"hdr metadata":"unset","natural size":"1280x720","orientation":"0°","profile":"vp9 profile0","visible rect":"0,0 1280x720"}]

Is it possible to make h264ify work with Facebook as well?

Thank you very much in advance.
