Comment (by peter_b):

 This would be a valuable feature indeed. Especially, since it would make a
 lot of bash-scripting around the transcoding obsolete.
 It would also make this framemd5-validation transcoding available to more
 users, since it'd be easier (and faster, too?)

 It might also be great to be able to provide a framemd5 file of the source
 as optional argument:
 This would save computing time for re-generating the framemd5 again, if it
 was already generated in a digitization workflow already, for example.
