CCS/TDA3: Video algorithms debug on TDA3, video input

Part Number: TDA3

Tool/software: Code Composer Studio

We develop some image recognition algorithms on TDA3.
But we got question, how to do it in the right way.
On another nVidia Tegra based development board we just put video file into device (linux device file) that equal capturing image from cam. After it we can debug algorithms.
But TDA3 hasn't video input and hardware decoder, so we can't just put video stream into device file.
We should capture image direct from camera, because it's only one source of video in TDA3. So we can't debug in office because there are no image of road. Or we should capture image from projector or another display. All these variants are not right for developing as you understand.
We think there are should be something like CSI2 camera emulator or another interface for this task.

Finally, how to debug video on TDA3? How to input captured video stream into TDA3?

    Hi Vladimir,

    In VisionSDK there is an example usecase "NullSrc -> Decode -> Display",
    located in <VisionSDK install_dir>/vision_sdk/examples/tda2xx/src/usecases/network_rx_tx,
    where "NullSrc" link can be used to read a file from SD card or network.
    You can check there how to use NullSrc and create your own usecase that
    uses NullSrc to read a file and then process it.

    Regards,
