Drop adb reverse. Accessory bulk carries length-prefixed H.264 access units into MediaCodec, and every tablet's HTTP tunnel uses the daemon port.
LAN login terminates on 127.0.0.1 just like the AOA proxy. Annex-B over USB runs only when that port is the accessory proxy, so Wi-Fi keeps ExoPlayer.

Summary
USB video no longer depends on
adb reverse. The host sends length-prefixed H.264 access units on the Android Open Accessory bulk pipe, and the tablet decodes them with MediaCodec. HTTP session and input still ride the accessory TCP proxy. MPEG-TS/ExoPlayer stays the Wi-Fi path through the LAN TLS proxy.The second commit keeps that proxy from being mistaken for USB. LAN login also uses
