This weekend I was thinking how to make my webcam connected to
OrangePI send a picture “on demand”. There are daemons (e.g. motion or
webcam-mjpg) which do this but they capture images even when you are not
watching and I wanted to avoid this. There are also projects (fswebcam)
which are able to take single picture, save it to disk and end. I just
needed to run it after http request and send back the image. Installing
full webserver with some kind of interpreter (php, lua,…) seemed to me
like an overkill. So I came to an idea to use inetd.
And this is how I did.
