Please provide complete information as applicable to your setup.

• TensorRT Version
• NVIDIA GPU Driver Version (valid for GPU only)
• Issue Type( questions, new requirements, bugs)

I build a pipeline like below

uri_source_bin->nvstreammux->nvvideoconvert->jpegenc->nsmsgconv->nvmsgbroker.

And I append a src_prob for jpegenc, inside this prob I attach some event into batch_frame_meta. (Just like the example in test4).

But the problem is, nsmsgconv goes to stuck without any error, After I add some log trace,
I found it is stuck in below step.

NvDsEvent *eventList = g_new0 (NvDsEvent, g_list_length (user_meta_list));

the g_list_length (user_meta_list) cause some error. It seems user_meta_list point to some undefined address.

do you want to send the jpg files to kafka server? could you narrow down this issue? if not add event in src_prob, will the application hung?

The problem is inside both nvmsgconv and nvmsgbroker, it can only handler cap is video.
But my pipeline is jpeg. So it can’t work. I have to customize my special msgconv and msgbroker to handler this case.

Sorry for the late reply, Is this still an DeepStream issue to support? Thanks!
