[MEncoder-users] Is there a tool that can report on the structure of mpg files?

[John Bovey]

The subject says it all, really. I am new to this mencoder, mjpegtools
world and I am frustrated by the fact I can use different tools and
tool options to create mpg files that look superficially the same, but
which are obviously very different internally. Is there any free tool
that can analyse an mpg file and print out information about its
internal structure?
