hi

in my application, I need to create and process a stream of 1600x1200 resolution at ~20FPS, in RGB format.

is this a supported configuration, in terms of ISS, video codecs etc  ?

I have the appro IPNC RDK ver 3.5

    Ron,

    1600x1200 resolution with 20fps processing can be supported. I have few questions:

    1. Which video codecs do you want to work with, for example if its H.264 you will need to use YUV420 output format for the frame buffer.

    2. Also do you want to use color processing from ISP? 

    3. Which image sensor are you planning to integrate?

    Regards

    hi Rajat,

    the main data path needed for this application is RGB888 from the ISS to the C674 DSP, using the 1600x1200 resolution.

    h264 will be used for streaming video, probably with overlay graphics.

    currently i'm using the MT9J003 sensor that comes with the appro kit, but this is not yet decided for the product. I need to know

    what are the options, for example if we select a different sensor.

     

    regards

    ron

    Hi Ron,

    ISS RSZ can be used to output RGB 565 or RGBA (32-bit) formats.

    RGBA will be 4 bytes per pixel (A + RGB888).

    We dont support this format in the IPNC release software, so if you need to use it you will have to make the changes in ISS drivers (RSZ output format) and mcfw (buffer allocation for frame). ISS to DSP connection is possible and supported by the framework.

    Regards
