I built a dynamic pipeline similar to nvidia’s official python app runtime_source_add_delete.
Everything works fine, except when release_request_pad() function called on nvstreammux, which takes me about 40 ~ 160 seconds to release the pad.
Why was that happened and how can I fix it? Could you give me any clue? Thanks forward.

1 did official python app has the same issue in your enviroment?
2 please provide your logs, for example, redirect log to a file , like this: app >1.log, 2>1.log.
3 could you provide your code diff?
Official python app itself works smoothly; I found the reason why my app it is slow.
Cause I occasionally set the property
sync-inputs=True, which is different with my sink element’s property
If set them both True of both False, them my app works fine.
could you provide your code diff? only sink.set_property(“sync”, 1) ?
Yes, I reproduce the issue on the official app, I’ll post soon.
myapp_deepstream_rt_src_add_del.py (18.6 KB)
I only modify few lines of code:
- add timing in stop_release_source function
- add a sink probe to print buffer timestamp to notify that gstreaming is running
Here is the diff result:
And here is result after running the code:
The thing I found is that when
sync-inputs on nvstreammux is different from
sync on sink, the issue appears.
Why is this happened? Could you give me any clue?
what is your video source? Using your code I can’t reproduce the hung issue, my test video is deepstream’s sample_720p.mp4.
I sent you a message containing my test video. Thank you very much.
I repeatedly reproduce the issue on DeepStream Official Container environment (devel version).
Hi, do you have any progress on this issue?
1 if only adding “streammux.set_property(“sync-inputs”, True)” in python code, I can reproduce this hung issue by your video file, deleting some sources will cost more than 40 seconds.
2 sync-inputs means “Boolean property to sychronization of input frames using PTS”, maybe sychronization will cause to wait, I will check, you can set it to false for workaround.
OK. I set it false by now. Thank you very much about your effort.
If you have any news about it, please let me know. I’m appreciate about that.
