 I doubt it ever will be since there are no sponsors for it.

 Although I never actually tried it, I think the identity single-segment thing 
will do want you want automatically if you select your chunk using a seek 
event.  The seek event will be interpreted by the demuxer, and I believe it 
will send a synchronous newsegment on all its src pads.

 I don't know how to do it in perl, but it's probably similar to the way you 
do it in C.

 You have to push an EOS event to an element or a pad upstream from the mixer.  
You can choose any element, but probably the source element (souphttpsrc?) is 
the easiest.  In C it would be something like:

    gst_pad_send_event(srcelement, gst_event_new_eos());

 Actually, it's possible that just setting the source element state to NULL is 
sufficient to trigger the EOS.  You anyway have to set the source element 
state to NULL, otherwise it will keep on pushing buffers after the EOS, which 
is not allowed.

 After sending the EOS, you can wait for an EOS message to appear on the bus.  
This message indicates that all sinks have recieved an EOS.  After that you 
can tear down the pipeline.

 Arnout
