Rear Dashcam 1.0 for Gen5W

Rear dashcam 1.0 for Gen5W head units (Android 4.4), as a NEMESIS package: the recorder service and the Dashcam playback app in one install.

Changes in this version:

Rear Dashcam 1.0: first supported release, for the IONIQ 5 SE and SEL

• Supported on the Hyundai IONIQ 5 SE and SEL (plain backup camera, no 360° view). The installer refuses other models, and still refuses 360°-view cars such as the IONIQ 5 Limited.
• Needs NEMESIS 1.16 or newer and Video Codec Fix (media.codecs) 2.1 or newer, which is required for playing recordings on the car's screen. Update the codec package to 2.1 first. NEMESIS now checks for it when you install, and won't uninstall it while the dashcam is installed.

As always, reboot the head unit after installing or updating, so the camera picture stays hidden under Android Auto and CarPlay.

Install gen5-codec-patch (media.codecs 2.1+) first. It's required for on-device video playback. Needs NEMESIS 1.16 or newer. Only for the IONIQ 5 SE and SEL (no 360° view); the installer refuses other cars.

Install over ADB with nemesis install --update dashcam-1.0.zip, or by USB: extract dashcam-1.0-usb.zip onto the root of a FAT32/exFAT drive and plug it in. Reboot the head unit after installing or updating to activate the camera overlay fix. Recordings and the recording on/off setting carry over when you update. Check downloads against SHA256SUMS. DashcamPlayer.apk is the app on its own; the package already contains it.

If the reverse camera ever fails to come up, stop and report it, and uninstall the package until it's fixed. Details in the README.
