It can't be that hard to try these files on your  mips machine. Or are you perhaps using QEMU yourself? I actually installed it here today for the sole reason of testing with FFmpeg, but it is a slow, cpu-hungry bugger here that makes the fan on my laptop spin constantly.

i use qemu-mips myself
mips is not fast, building on mips is really slow if one did that

also cross building to mips should be the same speed as building to
x86 would be
qemu-mips would only run for a few seconds to do whatever you want
to test.
I assume you would test 1 image and not a whole movie
