MPEG1 over MPEG-TS on a WebSocket, decoded in JavaScript and painted to a canvas. Every number above is measured in this browser and submitted with the session.
Quality picks the rendition de1 ingests and re-encodes; what crosses the car's link is the preset's own bitrate, which is why preset A (2 Mbps) is the default. The fits/exceeds tag on each rendition compares it against 3.5 Mbps — measured in the car on 2026-09-19 at 3.1 then 3.9 Mbps, 310–340 ms RTT — so the tags read the same here as on /3, where the rendition is copied rather than re-encoded and is what the car receives.
