Does the board generate events, such as HDMI connect/disconnect?
You may share more information about the HDMI2CSI board so that forum users can help share experience.
The HDMI2CSI https://github.com/InES-HPMM/linux-l4t-4.4/wiki/hdmi2csi converts an HDMI input to a CSI output. The standard v4l2src is then used to capture the result via the CSI input on the TX2.
The v4l2 documentation https://linuxtv.org/downloads/v4l-dvb-apis/uapi/v4l/dev-event.html indicates that v4l2 can generate events indicating loss of signal. The API does not appear to provide any standardized events for that purpose, which would imply this is hardware dependent.
I was looking for any information on these events, specifically in the context of the TX2 CSI capture and the HDMI2CSI.
