[gst-embedded] to control tee plugin

[sunwenmao]

Hi,

The mistake “}” is made by me with a copy error carelessly, sorry! 

In fact, I just want to use tee plugin to produce two video streams from pad0 and 

pad1. When one of the two pads is closed, the other can still work normally, that

means I can control any one of them to realize the function of opening and closing

at any time. But now, when I close one pad, both of them do not produce video 

streams, and the solution has been not found until now!

Can you help me and thanks a lot!

 

Best Regards

that code looks wrong - thre is an unmatched "}" on the 2nd line. Maybe you
could tell us what you want to do. Quite likely there is a better approach, that
does not require changing the element code.
