    It seems you need to use Vision SDK. Please search for "omnivision" in the forum e2e.ti.com/.../791.

    Hi,

    Please ignore my previous response above. I did some research, it seems some omnivision usb cameras are not UVC device. Please check if yours is.
    Attach your omnivision camera into a Linux PC, run the following command and provide its output.
    $ lsusb -v -d <camera vid:pid>

    Hi,

    I cannot help you on sending video over 4G, this is a system query.

    But using gstreamer on AM5728x Processor SDK Linux is no difference from using gstreamer on Linux PC, there are plenty of information on Internet. basically you do "gst-launch v4l2src device=<your-camera-device-node> ! <video-format-setting> ! filesink location=<where-to-save-the-video>".

    Before using gstreamer, you have to know if the camera is supported in Linux or not, that is why I asked you to provide the camera usb descriptors.
