OV5640 DV camera + mjpeg_streamer not working #63

Closed gavan1 closed 3 years ago

gavan1 commented 3 years ago

USB camera works as per docs.

OV5640 DVP example is incorrect.

OV5640 DVP is listed in video1 not video2.

/dev/video1

"mjpg_streamer -i ./input_uvc.so -d /dev/video1 -r 1280x720 -q 90 -n" -o "./output_http.so -p 8080 -w ./www"
