• Requirement details( This is for new requirement. Including the module name-for which plugin or for which sample application, the function description)

I have used the deepstream-transfer-learning reference app to write the save_image function. During running of the stream at some point of time (not fixed) I hit an error which says

Empty JPEG image (DNL not supported)
deepstream-app: …/…/src/hb-object-private.hh:154: Type* hb_object_reference(Type*) [with Type = hb_unicode_funcs_t]: Assertion `hb_object_is_valid (obj)’ failed.
Aborted (core dumped)

Can you provide the method to reproduce the error? We can not know what happened only with the above description.

@Mike I have seen your code. There are a lot of customized code based on deepstream_app_main.c. So the “Empty JPEG image (DNL not supported)” is not caused by our code.

This error happens in common harfbuzz library which is an open source tool for graphics. So you need to debug your code by yourself.
