Read canvas image by HTTP: Difference between revisions

== Status (1/2019) ==

This feature was merged into the official 2018.3.1 release. It works so far. However, there are latencies and the solution isn't efficient. Just creating the PNG image from OSG takes up to 100ms.

For the time being, this should still be considered a "proof-of-concept" that may go through more iterations of optmizations. Integrating it into 2018.3.1 makes it possible to explore a number of opportunities to optimize the whole thing for different use-cases and solicit community feedback. Special attention might be required with situations where the canvas and/or the connection are shut down, but also to support [[Reset & re-init]] without causing a race  condition.

{{Note|In its current form, the streaming capability <ref>https://forum.flightgear.org/viewtopic.php?f=71&p=297716#p297716</ref> is available but might overburden the flightgear process, depending on the number of canvases displayed. Its recommended not to use the streaming feature but to refresh the canvas from the browser. If any instability of FlightGear occurs, the remote canvas feature should be disabled for checking whether it is the reason.
