I want to mix two video streams together using compositor element, 
first I add one stream in to the pipeline:
   videotestsrc pattern=ball ! compositor name=mix ! autovideosink

Then I build an appsrc with push mode and add it :
    appsrc ! mix.

Then the video hangs there if I do not push data, how to avoid the hang, I
want the compositor to continue works whether or not my appsrc push data,
please help, thank you
