HTTP API

FullView for NDI runs on port 9901, and listens on all interfaces. The following HTTP API routes are available.

GET: /display/{displayNumber}/source/{name}

Changes the NDI source assigned to a given display, starting at display 0.

curl http://tractuspc1:9901/display/0/source/ALPHAVII%20%28Test%20Pattern%29

GET: /displays

Gets a list of displays. Will eventually return display bounds and positions.

GET: /debug

Returns performance information for the main renderer.

Performance Metric	Description
SdlEvents	The time it took in a given render cycle to process Windows-related UI events (mouseclicks, etc.). This should be < 1 msec.
BlitRender	The time it took to render the scene before sending it to the GPU and waiting for vsync.
RenderLoop	The total time, including SdlEvents and BlitRender, to render and present the scene. Should be close to 1000 / refresh rate (i.e. for a 60Hz refresh rate, this should be 16-17)

If BlitRender is taking more than 16 msec, that means your PC cannot render the entire canvas within 16 milliseconds. When diagnosing performance issues, BlitRender is the most important number to interpret.
