Yi 4k and 4k+ Cameras

It's a nice camera but it has no documentation anywhere. It uses an ambarella SOC and has two operating systems which run at the same time on it: an RTOS and Linux. The RTOS does everything (encoding, the gui on the camera, etc...) while the linux barely does anything (it hosts a web server and some software that passes commands received from the network or bluetooth to the RTOS).

In this repo there is:

4k Stuff for the yi 4k.

4k+ Stuff for the yi 4k+.

For both the 4k and 4k+

Bitrate Mod The bitrate mod.

Firmware Unpacker Firmware unpacker for the 4k and 4k+ firmwares.

Useful autoexec.ash Commands Some useful autoexec.ash commands.

Telnet How to enable telnet on the camera.

Live How to create qr codes for the live streaming mode.

Settings Some notes on camera settings.

Dump Camera Settings Dump camera settings to a file.

Enable RTOS Logs Enable RTOS logging to sd card on the camera.

Camera Controller python script to control one or more cameras over wifi.
