OWNLOAD
Special HTTP commands are available to enable automatic or script downloading of archive files:
wget --user=admin --password=ncast http://192.168..0.100/rest/files/recordings/20120926-061931-001.mp4
wget --user=admin --password=ncast http://192.168.10.100/rest/files/recordings/20120926-061931-001.xml
where
file.mp4 The time-stamped archive filename obtained from the downloaded list
file.xml The time-stamped xml file associated with an archive file.
Note that archive operations are username/password protected and this information must be supplied to
utilize these special URLs. The required username is “admin”. The password is entered on the
Configuration → WEB page.

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:
wget --user=admin --password=ncast http://192.168.0.100/rest/files/preview.jpg
The default settings are format=jpg, quality=85, and the width and height will match the current settings
of the session frame size.

PLOAD
Overlay graphics used in presentations may be uploaded dynamically through use of an upload utility
program. When used in conjunction with a scheduler or serial interface command controller this leads to
a powerful method to configure all aspects of a Presentation Recorder for a given Session. It allows
custom templates to be changed on an hourly basis, for example.
You can upload a channel overlay with this command:
curl -0 --digest -u admin:ncast -F "overlay_1_1_file=@test.png" http://192.168.0.100/rest/files/upload
This will upload the first overlay on Channel 1. Option "-0" is required because lighttpd is not handling
HTTP 1.1 upload correctly.
