An all-in-one daemon that exposes an HTTP frontend to
- adjust settings ;
- manage OSD regions ;
- stream AV content on supported IP cameras
Example of a quick test setup for SigmaStar processors:
curl -s -L https://github.com/OpenIPC/osd/releases/download/latest/osd-star -O
chmod 755 osd-star
The Buildroot package is ready; the resulting file will be called "osd_server":
make BOARD=ssc338q_lite br-osd-openipc
make BOARD=gk7205v200_lite br-osd-openipc
make BOARD=hi3516ev300_lite br-osd-openipc
Parameters for each region can be passed in one or many calls:
curl "192.168.1.17:9000/api/osd/0?font=comic&size=32.0&text=Frontdoor"
curl 192.168.1.17:9000/api/osd/0?posy=72
N.B. Ampersands require the address to be enclosed with double quotes under Windows or to be escaped with a backslash under Unix OSes
Supported fonts (sourced from /usr/share/fonts/truetype/) can render Unicode characters:
curl 192.168.1.17:9000/api/osd/0?text=Entrée
Empty strings are used to clear the regions:
curl 192.168.1.17:9000/api/osd/1?text=
Specifiers starting with a dollar sign are used to represent real-time statistics:
curl 192.168.1.17:9000/api/osd/1?text=$B%20C:$C%20M:$M
N.B. Spaces have to be escaped with %20 in curl URL syntaxes
Showing the time and customizing the time format is done this way:
curl 192.168.1.17:9000/api/time?fmt=%25Y/%25m/%25d%20%25H:%25M:%25S
curl 192.168.1.17:9000/api/osd/2?text=$t&posy=120
N.B. Percent signs have to be escaped with %25 in curl URL syntaxes
UTC date and time can be set using Unix timestamps:
curl 192.168.1.17:9000/api/time?ts=1712320920
Bitmap files (.bmp) can be uploaded to a region using this command:
curl -F data=@.\Desktop\myimage.bmp 192.168.1.17:9000/api/osd/3
N.B. curl already implies "-X POST" when passing a file with "-F"
