TDA3XEVM: ISS Raw capture from multiple cameras

David Dominguez Moises

Part Number: TDA3XEVM

HI,

I've been using TDA3 to stream from multiple cameras on HDMI display. Have also added a custom usecase where I can send a raw capture from 1 ISS channel over ethernet.

Now I would like to have sort of a combination of these 2 cases and be able to get raw captures from multiple cameras over ethernet.

My resolution and fps are very low, so this transmission should be good over Gig Eth in terms of bandwidth.

How could I implement this?

Thanks,

David

Hello David,

There is support to capture RAW stream to SD card (or SSD drive). Will this be acceptable instead of Ethernet?

HI Mayank,

This is ok, but my question would be how to modify an existing usecase (surround view calibration ISS) to store the raw captures from multiple cameras rather than a single one.

Currently the ISS 1CH usecase supports raw capture from 1 camera.

Surround view calibration ISS only supports YUV capture for multiple cameras. Need to do raw on my application.

Best,

David

David,

SRV calibration app is based on generic multi camera app (app_multi_cam). app_multi_cam has the ability to save RAW images for all the cameras. You may either use app_multi_cam, or migrate the raw save features into SRV calibration app.

Hi,

I was able to capture raw from multiple cameras on the surround view calibration use case. Currently I have to do this for each camera, one at a time.

Is there a way I could save the raw captures from multiple (in my case 4) cameras into a single file?

Thanks,

David

No this is not supported in the SDK. But you maybe able to modify the application code to achieve that.
