* WIP adding second websocket handling for cameras * just more WIP * even more wip. Most java-side framework completed, but not yet debugged * IT LIVES. Still needs lots of cleanup. But we're transferring and displaying data! * moved down an architecture layer. Improved multiple-camera handling * Additional WIP to help improve smoothness and performance, though not yet tested * bugfixes galore * tweak compression * spotless * more tweaks for handling slow/intermittent streams * wpilibformat maybe? * clang-format maybe? * WIP - adding thinclient. I don't like it yet, it should be more auto-generated than it is. * thinclient formatting fixups * Reduced amount of empty send data by limiting to only one stream per client (which is all we really need). Framerate is up slightly, overhead is down. * bugfixes, faster streaming, better mjpeg compression settings, thinclient working * spotless and formatting * cmon wpiformat.... * re-added mjpg streams * added a loading GIF to imporve the feeling of responsiveness * formatting * urlparams and built-in thinclient * wpiformat * prevent wpiformat complaints * Removed uint8 array and base64 conversion from client side * Synced up js implementations for ws streaming * formatting/spotless
