This is an attempt to control the MuxLab HDMI/SDI Signal Analyser model 500831 from Linux or Whatever OS and from CLI.
The current support is :
- Get/Set Volume level
- Get timings and frequency
- Get HDMI/SDI source type
- Get HPD standby status
- Get Picture DATA
- Get Selected EDID mode
- Get Selected EDID content
- Basic Address management
- Support for long frames (>256)
- Set HDMI/SDI source type
- Set HPD standby status
- Get full stream information (audio, HDR, HDCP, ...)
- Get AVI frame (AVI InfoFrame, ...)
- Monitor stream
- Set Custom EDID
Python3 is mandatory.
A single utility called muxlab-hdmi is provided to control the HDMI Analyser.
usage: muxlab-hdmi [-h] [--version] [--tty TTY] [--group GROUPADDR]
[--device DEVICEADDR] [--baudrate BAUDRATE] [--file FILE]
[--ratio RATIO] [--edid EDID]
