I want to covert above pipleline command to C language code with gstreamer<br>
native function.<br>
I confuse that how to use "mix" link other plugins in C language?<br>
(videomixer plugin named "mix"),I don't know how to convert ? I see some<br>
examples , they use C language to link between none-name plugins,I don't<br>
know that how to using name "mix" for videomixer plugin link each other in C<br>
code ?<br>
<br>
if you take time for solving my issue, thank you in advance, please write<br>
converting C code of above pipeline.<br>
<br>
<br>
