           Summary: proxy: Setting the base_time for dynamically added
                    pipelines does not work
    Classification: Platform
           Product: GStreamer
           Version: 1.14.0
                OS: Linux
            Status: NEW
          Severity: normal

I wanted to try out the new proxy plugin, and read in the proxysrc
documentation that the base_time and the pipeline clock need to be the same in
all involved pipelines. So I wrote a small test to try out a combinaton of
statically and dynamically added receiver pipelines (the latter are
GstRTSPMedia objects).

The statically added receiver pipelines work. The dynamically added don't. It
turns out that this is because the base_time is reset by something else, even
after I explicitely set the base_time to 0:

Note the base_time of pipeline0 and pipeline1.

I think the example given in the proxysrc documentation works because both
pipelines' base_time is reset to the same value.
