Detailed Description

An image frame received from the UVC device.

Field Documentation

uvc_device_handle_t* uvc_frame::source

Handle on the device that produced the image.

uint8_t uvc_frame::library_owns_data

Is the data buffer owned by the library? If 1, the data buffer can be arbitrarily reallocated by frame conversion functions.

If 0, the data buffer will not be reallocated or freed by the library. Set this field to zero if you are supplying the buffer.
