Streaming from payload camera

Hello, looking at the HDMI camera support section in the wiki, I am wondering if anyone has any examples of an HDMI stream being captured from a payload camera, for example a Sony a6000 or something similar, while still being able to use that camera as the main image sensor for mapping operations? Assuming the camera can take stills while shooting video and a mode change isn’t required. Thanks for the help.

The easier option may be to use a HDMI to CSI adapter since by default Open HD will search and use the CSI camera, however I am not sure if this will allow the Sony camera to stream and take stills at the same time, that may be up to the Sony camera settings/features
