Message Broker : only receive message from first source when there are more than one input streams

Continuing the discussion from Message broker and Multistreams in Python:

Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson / GPU)
• DeepStream Version
• JetPack Version (valid for Jetson only)
• TensorRT Version
• NVIDIA GPU Driver Version (valid for GPU only)
• Issue Type( questions, new requirements, bugs)
• How to reproduce the issue ? (This is for bugs. Including which sample app is using, the configuration files content, the command line used and other details for reproducing)
• Requirement details( This is for new requirement. Including the module name-for which plugin or for which sample application, the function description)

Using the deepstream_imagedata-multistream.py and added message broker into it.

pipeline.add(pgie)
pipeline.add(tracker)
pipeline.add(tiler)
pipeline.add(nvvidconv)
pipeline.add(filter1)
pipeline.add(nvvidconv1)
pipeline.add(nvosd)
pipeline.add(tee)
pipeline.add(queue1)
pipeline.add(queue2)
pipeline.add(msgconv)
pipeline.add(msgbroker)
pipeline.add(sink)
if is_aarch64():
    pipeline.add(transform)
streammux.link(pgie)
pgie.link(tracker)
tracker.link(nvvidconv1)
nvvidconv1.link(filter1)
filter1.link(tiler)
tiler.link(nvvidconv)
nvvidconv.link(nvosd)
nvosd.link(tee)
queue1.link(msgconv)
msgconv.link(msgbroker)
if is_aarch64():
    queue2.link(transform)
    transform.link(sink)
else:
    queue2.link(sink)

But only the first source meta data is receiving. I couldn’t find any solutions for python.

Can you add some log in broker plugin to have a check?

What do you meant by log in broker plugin. Sorry I couldn’t get it.

Please refer: Msgconv : only getting data from 1st stream when there are more than 1 streams - #6 by kesong

The frame images are also broken totally for multiple input streams!

Seems same topic with below. please refer it.
