Hello Brijesh,

          Now we want to use configure MST in DSS. Now we have created two gAppObj in openvx.

          One for 1280 * 640  map to pipe 1, another for 2772 * 1022 map to pipe 2. But I don't know how to configure DSS to merge the two image to one image side by side.

Hello,

You need to first set output resolution of  either (1280+2772 x 1022) or (2772 x (640+1022)), which means one of the parameters need to keep same and then you could set input video resolution in the pipeline and then position them side by side or top bottom manner. This is what exactly done in the above FAQ.

Hello Brijesh,

        And another question, does now the SDK support MST. We think MST and superframe maybe only can use each other. And how can we to configure MST for DSS. Because from Ser teams they suggest us to use MST mode

Hello,

No, MST is not supported in the SDK. No plan as of now to support this feature in the SDK.
