Comparing compression quality of h.264 encoders

[jonsmirl at gmail.com]

I'm evaluating several hardware h.264 encoders by feed them identical
videos to compress. The output files from these compressors are all
over the map in size. Does anyone know of a tool that would analyze
the h.264 streams and give me an idea of why I'm getting these
different results? I suspect there are bugs in a couple of the
implementations such that they are compressing, but not as much as
they should be.
