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