How to connect gldownload to omxh264enc

I'm running gstreamer 1.10 with openmax on a Raspberry Pi 3, and when I
attempt to use opengl to scale my incoming video, then resulting buffers
are RGBA, and they need to be I420 for omxh264enc.

When attempting to glvideoscale from RGBA to I420, I get the message
"Converting from RGBA to I420 requires functionality that the current
OpenGL setup does not support"

Is there a hardware accelerated way around this issue, or am I destined to
do software color conversion?

Thanks
