Set pipeline properties using gst-launch

Ian Gough
Does anybody know
​ 
the syntax
​ 
to set *pipeline* properties using gst-launch?
​ 
Not element properties, but rather properties on GstPipeline
​.


For example, with:

gst-launch-1.0  udpsrc uri=udp://235.118.190.108:5656 ! tsparse ! tsdemux ! queue ! h264parse ! avdec_h264 ! xvimagesink

​H​
ow do I modify this to set the pipeline latency which is
​ 
set programatically using
​ 
gst_pipeline_set_latency()
​?​

Let's say, you have to know, though it's documented in the man page.
Same pipeline with 40ms latency:

gst-launch-1.0 pipeline. \( latency=40000000 udpsrc uri=udp://235.118.190.108:5656 ! tsparse ! tsdemux ! queue ! h264parse ! avdec_h264 ! xvimagesink \)

Nicolas
