is it possible to receive real time information from MiniDLNA if and what media is served? Alternatively is it possible to see if and how many clients are connected?
Background: This is for a project that aims at automatic server suspend when the server is not needed.
There is no detailed information available today. But, since MiniDLNA is a forking server, maybe you can just see if the main daemon process has any children?
Makes sense, but: I'm streaming a music file right now to WMP, but I don't see any child processes to the MiniDLNA processes
Okay, so it really depends on your architecture, kernel, and C library. What kind of system is this? On a normal, modern x86 PC architecture with a halfway-recent distro, you should only have one minidlna process unless it's either scanning media or serving data to a client.
It's a very recent system. Core i3, Intel H55, Fedora 14.
I actually have three processes running all the time, regardless of media served. Eg, right now, no media served:
root ~$ ps ax | grep minidlna
2288 ? Ss 0:00 /usr/sbin/minidlna -f /etc/minidlna.conf
2304 ? S 0:00 /usr/sbin/minidlna -f /etc/minidlna.conf
2307 ? SN 0:00 /usr/sbin/minidlna -f /etc/minidlna.conf
There a three dirs though that I monitor.
But anyway, i'm looking for a more general way to figure out if media is served to a client. The method shouldn't be limited to my specific system or configuraiton.
A more generic (and pretty easy) way to do this might be to monitor network traffic. That's what I'm doing with my SrvrPowerCtrl plugin, which is a perl plugin for the Logitech Squeezeboxserver. I specifically added network monitoring so I could keep the server awake while minidlna is serving up videos.
