using

#define VIDEO_SINK "TIDmaiVideoSink"

I managed to compile a C program that display black/white on the composite output with the DM355SDK789311. The c code is very similar 18.2.3. Example application

http://gstreamer.freedesktop.org/data/doc/gstreamer/head/manual/html/section-data-spoof.html

 

For some reason compiling the same code with the DM355SDK840402 i don't get any output.  Can anyone be of help here?

Thanks
