+    title: Ender printer cams use Main-profile go2rtc transcode
+    decision: "The octoprint/octoprint2 H264 camera streams in go2rtc.yaml are transcoded with
+      a custom 'h264_octo' template (Main profile, level 4.0, capped 4-6Mbps bitrate)
+      instead of go2rtc's default High profile. This fixed choppy/slow video in the
+      Android HA app. Do not revert to the plain #video=h264 for these streams."
+    rationale: go2rtc's default High-profile H264 was incompatible with the Android WebView
+      MSE decoder, causing falls back to WebRTC and choppy playback. Main profile + capped
+      bitrate keeps 1080p and plays smoothly. Intentionally only affects the Ender
+      cameras; nest/blink streams left on default.
