I was trying to deploy ssd plugin in deepstream-app-test3. It can run successfully but always report a warning:
“(deepstream-test3-app:14261): Pango-WARNING **: Invalid UTF-8 string passed to pango_layout_set_text()”

Would u tell me the reason that cause this warning?

Here is the detail:

Hi,

You already got some perf log:

FPS for the last 300 batches: 25.03
FPS for the last 300 batches: 24.92

So the deepstream works correctly in your environment. The warning do no harm to the pipeline.
Thanks.
