Secure webcam streaming with mjpg-streamer and stunnel

Last week I was trying to understand how to establish a secure connection with a webcam streaming server. The idea was to setup a kind of small homemade surveillance system to be used when I’m away.

A way to extract the playback time from mpg123

In the last period I was working on a project concerning UPnP. In particular I was developing a “smart speaker”, a wireless speaker which plays mp3 files by streaming them from a NAS (UPnP media server). The code is written in Java and leans to mpg123, a real time CLI MPEG audio player/decoder. The hardware ...
