First, Happy New Year :-)

You need not do the steps above, as the GiP "--start" option
does exactly that already (from get_iplayer --long-help):

--start <secs|hh:mm:ss>  Recording/streaming start offset (HLS, rtmp and 
realaudio only)

pid=b06s6l5d is the 3hr long Christmas Day Official Chart on Radio 1.
You are obviously not on Windows ("terminal" was mentioned),
but here on Windows x86 if I use an incantation like:

get_iplayer-294.pl --type=radio --pid=b06s6l5d --radiomode=flashaac --raw --stream 
 --start 01:30:00 | "F:\Applications\VLC Portable\VLC 2.1.x 
Portable\vlc-2.1.5\vlc.exe" --file-caching=30000 -

then VLC starts the stream playback exactly at its halfway point:


The above command is particular to my own setup,
modify accordingly...
get_iplayer --type=radio --pid=<pid> --radiomode=flashaac --raw --stream --start 
<hh:mm:ss> | "path-to\vlc.exe" --file-caching=30000 - )

--file-caching is the VLC stream buffer size; increase the value, if your 
connection is flaky...
But the stream is being played back as it is being fetched by rtmpdump,
so no, I could not seek forward in time with VLC... :-(

Kind regards,
