In version 2.43 there is a new output format called “frameserver”. Does anybody know what it all about?
It’s used in complex high quality encoding pipelines. Basically an external program/codec dictates what should be rendered and when.
Select Frameserver, hit Anim button and then point your browser to localhost:8080.
