Hello,
You should add it like external decoder first:
[quote user="Rajeshkumar R"]One more thing , need to tell that in both applications(saLoopBack / saLoopBackFbdev ) query_dv_preset is failed for Set in [/quote]
If you are seeing this:
Mode set is 0
Setting DV Preset failed
this means that the input is its not able to detect the input resolution.
Please check IO expansion board is connected properly and the video source as well.
Make sure that you make the changes in the saLoopBack demo.
Best Regards,
Margarita
