APTURE
The HTTP Interface may be used to capture single images from the encoder. Commonly employed utilities
such as “wget” can retrieve the current composite frame for placement of the image on a web page or
elsewhere. Here is an example of the single command line needed (without the required user/password):
wget http://w.x.y.z/api.cgi?cmd=capture -O capture.jpg
All required capture parameters like format, frame size and quality are supplied as arguments in the URL.
You can override all capture parameters, for example:
wget http://w.x.y.z/api.cgi?cmd=capture&format=png&width=1024&height=768 -O capture.png
These parameters are supported:
format - jpg or png
width - 128 to 1280
height - 128 to 720
quality - jpeg quality 0 to 100
