Self-compiled FFMPEG binary or updated bundled default native binary??

I've an M-series iPad Pro and as such do have access to powerful hardware encoders for FFMPEG as well as ample memory for it to run without crippling the system too badly (as it might if it were running on a device with an older processor). I tried using the native FFMPEG that the app came bundled with but the FFMPEG version and library versions were pretty old. I'm wondering if it would be possible to run a self-crosscompiled binary from my Mac or another device within a-shell please. Am I correct in assuming that compiling it within the app on the iPad would not be feasible because of how many dependencies the compiler may have? I tried using the statically-compiled binary from my Mac on the app on my iPad (transferred it to it's own folder and switched to that folder using pickFolder) but the app continues to only recognize the native bundled version and not the one I moved there.

On the other hand, are there any plans to update the bundled FFMPEG binary or include a different fork/version for those of us with the headroom on our devices to handle it?
