One element could not be created. Exiting.


Yolo is not initializing … can you please confirm its not a bug ?

HI
Have you resolved this issue, you can do like this to check which element not created

if (!decoder)
{   
    g_printerr("decode could not be created. Exiting.\n");
    return -1;
}

if (!filter1)
{   
    g_printerr("filt1 could not be created. Exiting.\n");
    return -1;
}

similar like this, just one clip, please add all elements in this line
!pipeline || !source || !h264parser || !decoder || !filter1 || !nvvidconv || !filter2
|| !nvosd || !sink || !yolo

add them before this line: if (!pipeline || !source || !h264parser || !decoder || !filter1 || !nvvidconv
|| !filter2 || !nvosd || !sink || !yolo)
please make sure libraries needed like /path to ds package/usr/local/deepstream, TRT lib, CV lib, cudnn lib,
cuda lib, exported through export LD_LIBRARY_PATH=/path to the libs/, if you do not install them into system;
if you install into system, you do not necessarily do this.

@madhav.tidy Have you installed the yolo plugin before attempting to run the deepstream-yolo-app ?

Instructions are here https://github.com/vat-nvidia/deepstream-plugins#setup

Hi,

I have a similar issue while running yolo-app. The issue was in the creation of sink. To circumvent that, I’m trying to write it to a file but see the following errors, please see below. Any feedback you could provide would be greatly appreciated!

I’m using tensorrt docker container (tensorrt:19.03-py3) and have installed deepstream3 sdk. I’ve a display and the xterm works from the container.

Hi,
Can you add GST_DEBUG=4 before the app and run again to get more log for analysis?

Thanks for the quick response! Please see below for the output after executing: GST_DEBUG=4 deepstream-yolo-app /garage/DeepStream_Release/samples/streams/sample_720p.h264 config/yolov2.txt

Hi,
Can you point where you changed or generate one patch? the format gone, hard to compare with original

Hi, Please see below for the code changes (key blocks) tracked between // SNR begin, code block, // SNR end.

@amycao, any feedback on the errors observed while writing the output to a file?

“your app” > log 2>&1

Please see below, the output of the code that I posted above. Any help in debugging the issue will help. Instead of writing the output to a .mp4 file can I write the metadata to a file? If so, do you have a reference code/app? Please share.

Can you add below after line 220 and try again?
filter3 = gst_element_factory_make (“capsfilter”, “filter3”);
filter4 = gst_element_factory_make (“capsfilter”, “filter4”);

Thank you! This resolved the issue that I was facing.
