I love CasparCG and we use mostly own HTML templates for lower thirds, countdown overlays and stuff like that.
Now we are working on bringing a live heart rate into CasparCG but we have no idea how to do it.
In OBS it’s pretty easy since we use window capture of Golden Cheetah and the live heart rate.
As far as I know window capturing is not possible in Caspar and therefore not an option.
What else can we do? My first thought was to get the heart rate into json format and read it into the html template via AJAX but I don’t know any software which is capable of writing health informations like that into a local JSON-File in real time.
What are your thoughts?
