to elaborate on this slightly
when testing our code the output (should) only depend on our revission
so its easy to keep the checksum with our code
but when testing involves external libs the output would depend on
both our revission and the external libs revission making checksum
management and update much trickier.
A update to our codebase might need updating multiple checksums that
would need testing with multiple revissions of the external lib
similar a change to the external lib would require updating multiple
checksums and require testing with multiple ffmpeg revissions.
One could summarize it as that its unlikely that regression checks
with external libs will become very common except for simple cases
where an external lib has very stable output over time
