That has nothing to do with your original topic (capturing
stdout/stderr). get_iplayer aborts when rtmpdump fails during streaming
because, by definition, there should be no more programmes to process.
As you must know by now, this is a problem with rtmpdump, not a problem
with get_iplayer per se. Search the list archive:

You'll see that similar problems have cropped up many times before,
including several threads started by you. The answer hasn't changed
since you raised the same issue 3 weeks ago. There is no common cause
or common solution to rtmpdump glitches with iPlayer. The problem will
be something peculiar to your environment, and may only be temporary.
As always, if anyone has better information, step up and be a hero.
In this particular case, the output provides a clue:
INFO: Connection timed out, trying to resume.
As to why that is happening, we've no way to know. You appear have the
latest PPA version, so upgrades probably aren't the answer. Two very
long-shot suggestions:
1. Point get_iplayer at alternate CDNs (e.g., try --mode=flashvhigh1 and
then --mode=flashvhigh2). Alternate CDNs are generally only available
for TV programmes, and may not be available for every programme. It's
worth checking in case you're just hitting some duff servers.
2. Adjust the rtmpdump timeout parameter. Ideally, you should be able
to do this with --rtmp-tv-opts. Unfortunately, get_iplayer overrides
that and forces the timeout to 10 seconds, which should perhaps count as
a bug. For the moment you'll need to amend the get_iplayer script to
test this. Since you appear to have the PPA version, I would suggest
making a local copy of the get_iplayer script and working with that. In
the local copy, look for the line that reads:
push @{ $binopts->{flvstreamer} }, ( '--timeout', 10 );
Change the 10 to some larger number (30, 60, 90) and see if your
rtmpdump connection still times out.
