I was going to suggest
ffprobe -show_streams
I haven't got it installed at present, so I can't check whether it does what 
you want and shows the duration for the stream.

There are other suggestions here.

As I understand it, if you want support for incorrect handling of error 
conditions in get_iplayer, you will have to stop using Flash.  I suggest you 
try
--tvmode=hlsvhigh,hvfvhigh
if that is the resolution you want.  The new built-in HLS downloader is much 
faster than Flash, although you may not see any benefit if you have a slow 
connection.

I am not sure that what you are trying to do will solve your problem.  Take 
What Women Want (b0074dkr) as an example.  duration in --info is 7140. 
runtime is 199.  The actual length is 1h 54min 49s, so you will conclude 
that 4min  11s is missing.
