Hi,

The image is saved via OpenCV.

Please note that the function is called per frame.
So the filename should be set according to the frame index.

You can find a python example below:

Hi,

Since both follow the same SDK.
You can use a similar source code to get the images.

Thanks.

ok i will try your advice way.
and i may get crop image from custom test5 right now, but i have to get full frame with object on my test5 codes for my project.
and i am confuse another question, i mkdir a path name with output, and OSD_XXXX pictures can be put inside output dir,
but many images like 60_xx_xxx_xx (i think begin by fram number) can not put to there, could you tell me how to deal that?

thank you many much!

Hi,

Do you want to change the output path.
Or meet some error (ex. permission) when saving the image?

Thanks.

thanks!

Hi.

You can update the file name directly.
For example, to save images into /home/nvidia/.

img_path = "/home/nvidia/{}/stream_{}/frame_{}.jpg".format(folder_name, frame_meta.pad_index, frame_number)

Thanks.
