That works! Thank you I tested out 5 webcams with both dummy.tidl and classificatin.tidl 1. Logitech C920 webcam works 2. VERY Old Creative VF0230 webcam - did not work 3. VERY Old trinket AMD Smarter Choice webcam -images torn up with overread errors-n as n goes randomly from 1 to 8 4. OLD Silicon Motion SM731 webcam works 5. OLD EyeToy webcam - occasional image tears
check out https://elinux.org/RPi_USB_Webcams for some camera info. I modified the common Makefile and it works. Just for curiosity I modified the local Makefile as well and I's weird that the LOCAL Makefile is corrupted when I rebooted the board. It came up with a dialog box asking if you want to reload file from disk (that Makefile was modified in previous session and saved "-r /dev/video1" similar to the common Makefile) . If I clicked "Y" it showed the correct mod -d/dev/video1, and if I clicked "no", it showed -d /dev/ On Thursday, March 26, 2020 at 10:23:17 PM UTC-4, jonnymo wrote: > > In the GitHub issue that was filed, I noted the following which seems to > get the camera active again: > > > > Setting '-d /dev/video1' in the common Makefile seemed to do the trick.
