Using two different scalers

Hi,

        I want to use two scalers in my omx application (ezsdk 5.04, dm8168).  The application has two layers as mentioned below:

        Layer 1:     Capture -> Scaler -> Display

        Layer 2:     Decode -> Scaler -> Display

        The scaler in layer 1 is used only to do chroma upconversion (420 to 422) whereas the scaler in layer 2 does some actual scaling.

        I tried to use the same scaler (OMX.TI.VPSSM3.VFPC.INDTXSCWB) in both the places but it failed.  How can I use two different scalers here?

Thanks,

Senthil

    Senthil,

    What's error you are getting ? is it not getting created ? We will be releasing EZSDK 5.05 soon, which would have decode_mosaic example utilizing up to 4 instances of SCWB. You could use DEI in layer 1 as capture_encode example does.

    Regards

    Hi Vimal,

                    The error turned out to be due to some other issue.  I am able to use the scalar in both the layers.  I am just curious to know if there will be any performance degradation due to scaling 2 different video streams with the same scalar (or 4 streams in case of EZSDK 5.05).

    Thanks,

    Senthil
