Show HN: Android client for DJI Osmo action/handheld cameras

For the past few months I've been hard at work reverse engineering the DJI "DUML" protocol that the Osmo Action 5 and Osmo Nano cameras speak. The DUML protocol is already documented but for drones, and a lot of the commands that are action camera specific were missing. Decided to build this Android app to replace the proprietary DJI Mimo vendor app, since it calls many Chinese IPs, has ByteDance SDK embedded and has a bunch of bloat and stuff I don't use. I just needed the app to download videos and photos from the cam.

Camera compatibility:

- Osmo Nano

- Osmo Pocket 3

- Osmo Action 6

- Osmo Action 5 Pro

- Xtra Edge Pro (it's a DJI shell company: https://www.theverge.com/report/795016/xtra-muse-dji-osmo-po... , I bought one in the US as a memento lol)

Want to test with:

- Osmo Action 4,3,2

- Osmo Pocket 2/4

WIP support for certain DJI drones as well (works with my Mavic 3).
