Hello
I have an Rpi-4 with an ArduCam 16MP cam attached.
Running latest bookworm with Raspberry Pi Desktop:I have a small Flask application to stream video to a simple index.html page.
The streaming works just fine. However, the streaming image is blurry and I cannot get the stream to auto-focus
From the Raspberry Pi Desktop, I open a CLI window and issue the following:This works - I can see the autofocus working and the image begins streaming within a second or two.
Creating a sample image, create a very sharp/clear image as wellI've fiddled with this for quite some time, trying different options to get autofocus working.
My objective is to stream, in near real time, from a RaspberryPi residing on my Wifi network to a PC residing on the same network. The PC views the stream by navigating to the Raspberry PI IP address.
I tried getting rpicam-vid to stream via my Flask app but could not get that to work.
I am open to alternative approaches gstreamer or rpicam - my key goal is a real time (or near real time) video stream via Flask.
Any ideas/suggestions would be appreciated.
Regards
