Gst-nvmultiurisrcbin is not sending all frames to downstream elements

Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson / GPU): Ubuntu/ RTX 2080 Ti
• DeepStream Version: DS7.0
• JetPack Version (valid for Jetson only)
• TensorRT Version
• NVIDIA GPU Driver Version (valid for GPU only)
• Issue Type( questions, new requirements, bugs): Bug
**• How to reproduce the issue ?
My pipeline is as follows: multiurisrcbin is not sending all the frames to the downstream for a given file input. For example, if a file contains 578 frames, multiurisrcbin only sends 552 frames to the downstream. The 26 end frames are not sent to downstream. This issue is not observed in DS6.2.

How did you measure the output frames? With which pipeline and what are the configurations?

The processed frames count is equal to number of messages sent to message broker, as multiurisrcbin batch size is 1. I added a probe at queue(element after multiurisrcbin) sink pad, the probe function is called only 552 times. I think the pipeline configuration doesn’t any impact to reproduce this issue. I think the issue is in multiurisrcbin.

@Fiona.Chen , we are observing same issue with multiurisrcbin. it is easily reproducible with file source instead of RTSP.

I’ve tried the following pipeline and got 1443 frames which is exactly the same frame number in the DeepStream SDK sample video “sample_1080p_h264.mp4”.

There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one. Thanks
