If it's a binary file, you shouldn't read it by "lines", which is what
this does. You should probably use the read function instead; that
will let you specify how many bytes to read at a time. (And is a while
loop the right construct for the operation you're performing?)
if ($_ =~ /\xFF\xC0/) { # Start of frame header.
print "Found start of frame at $start\n";
Where did you put a value into $start?
Finally, it looks as if you're looking into the data of a jpeg/jfif
file. Isn't there a module that will help you do what you want without
mucking around in the raw bytes?
Hope this helps!
