Hi,

is there any way to start/stop a recording of a certain channel via a programming interface? For example via a http request?

What I'm looking for is something like

http:xxx.xxx.xxx.xxx:9981/record/channelid/on
and
http:xxx.xxx.xxx.xxx:9981/record/channelid/off

Thanks in advance, and thanks for this great piece of software!
mike
