I can run deepstream-image-meta-test example.
But the screenshot is an image of each target.The existing effects are as follows：

I want to save image with bounding boxes. How should I modify the program?The desired effect is shown in the figure:

Below function will encode the obj. Seems you can make one obj for the whole frame and send to encoder.

    nvds_obj_enc_process (ctx, &userData, ip_surf, obj_meta, frame_meta);

**We used this function in deepstream-image-meta-test example，and the effect of the screenshot is:

And this function is encapsulated, we can’t refer to it and modify it, can you help me give a function for frame encoding. Thank you so much.**

Here is the doc of the API.

I want to cut the big picture, not just the target. So you mean let us refer to this source code to modify it?

[kesong]

Yes. you get the object as you send obj_meta to the encoder. Please change the obj_meta to the meta data which contain one bigger BBox which cover the whole picture.

nvds_obj_enc_process (ctx, &userData, ip_surf, obj_meta, frame_meta);
