Part Number:PROCESSOR-SDK-AM437X
Tool/software: Linux
Hi,
running this with PSDK 3.2.0.5 on an AM437x EVM, here are my observations
[] detect_barcode using the sample_barcode.jpg works
[] detect_barcode with live camera
root@am437x-evm:/usr/share/ti/image# detect_barcode 1 1 1
VIDEOIO ERROR: V4L: index 1 is not correct!
Frame per seconds : 100
init done
Using Wayland-EGL
wlpvr: PVR Services Initialised
This works with /dev/video0 (if this is the only camera connected). It fails if additionally the second camera is connected to the EVM.
This demo starts running with the live camera, and at slower frame rate, barcodes are being detected.
Eventually letting it run the demo hits a seg fault ...
root@am437x-evm:/usr/share/ti/image# detect_barcode 1 1 1
VIDEOIO ERROR: V4L: index 1 is not correct!
Frame per seconds : 100

Segmentation fault (core dumped)
I also wanted to check on the performance and framerates. The demo seems to be architected for functionality. Could someone comment on how the performance can be optimized?
Thanks,
