Stopping command-line gst-launch, after processing certain no. of frames

[Wesley J. Miller]

Many of the src elements have num-buffs properties that you may use to
limit the number of sourced frames.  Some, however, do not.

I suppose someone of us <grin> needs to write an element that accepts a
time to run or a number of buffers before issuing an EOS to the pipeline.

Sink pad - any caps
Src pad - any caps
Properties:
   name         as usual
   timeout      UINT64 n-secs - readable, writable, default = UINT64_MAX
   num-buffs    UINT64 - readable writable, default = UINT64_MAX

Sends EOS to the pipeline when time >= timeout OR number_of_buffers >=
num_buffs

Of course this would be pretty useless in a C (or whatever) program since
they have more sophisticated mechanisms to halt the pipeline, e.g.
External timers sending the EOS.
