TDA4VH-Q1: Regarding the problem that the multi-camera cannot connect to the DCC

Part Number: TDA4VH-Q1

Dear TI experts,
Recently, we found a problem when debugging binocular camera or multi-camera. After we light up multiple cameras at the same time, our DCC tool can only connect to the cameras in one of the channels. For example, currently we start two APP_SINGLE_cams at the same time. We can run both cameras at the same time by distinguishing between SensorID and channel_id, but our DCC tool can only connect to one of them. How do we solve this problem?

    Hi Chenzhe,

    I suppose we have only used and tested DCC tool with one single camera app running so far.
    I am not sure how the tuning server works when you have 2 single-cam apps running at the same time.

    I am copying my friend for his comments.

    Hi Chenzhe,

    How are you streaming two single-cam instances?

    Live Tuning two single-cam application instances is not possible with our current implementation. The limitation being two single-cam instances cannot listen to a single port at the same time.

    To enable Live Tuning on multiple instances of the single-cam app, changes would need to be made including:

    • Allow to initialize multiple app objects associated with their respective single cam app
    • A single ITT server that handles incoming requests and uses the corresponding single-cam callback

    Best,

    Brandon
