Currently running hailo-apps-infra 2025-10 on Raspberry Pi 5 since its release few days back.
The output starts fine but freezes after half a minute-or-so for multisource process using multisource.py - stock examples used as-is provided. Had set two custom video files (.mkv) @ 1280x720 for the two sources (viz: source_0/src_0 and source_1/src_1). Even tried with --disable-sync but still no improvement - same/similar results
Hey @Kingshuk_Das ,
Welcome to the Hailo Community!
Could you let me know which model you’re currently using? It would also be helpful if you could share the log file so I can get a better sense of what’s happening.
One thing you might want to try is lowering the frame rate and see if that helps. Also, is the issue affecting both streams or just one of them?
Let me know what you find!
Hello @omria
Thank you for the response.
Am using the default model yolov8m as-is based provided in the example. Have tried it with 15 fps but it still fails but a little later. Lowering it to 10-12 fps works but one of the two OSDs is very jittery.
Looks to me that it is likely arising out of a thread / memory constraint issue due to RPi5.
I shall eventually suppress it locally but ultimately I need to transmit the OSDs as a gstreamer composite stream to a remote server which would, I anticipate, eventually create the same issue/constraint.
Regards
Kingshuk
Hey @Kingshuk_Das ,
We’ve confirmed that the multi-source pipeline on Raspberry Pi 5 is experiencing CPU and memory constraints.
Based on your findings and similar community feedback, we’re prioritizing optimizations to the pipeline architecture. Our upcoming release will include improvements to streamline execution and reduce CPU overhead, which should resolve the freezing issue you’re experiencing with the multisource.py example.
We’ll have more details to share soon.
