Hacking

I reverse engineer stuff and make cameras better.
Choose your camera model to see hacks available:
Camera model Script type
GoPro HERO3 Black/HERO3+ Black/HERO3+ Silver Standard A7 scripts
GoPro HERO2/HERO3 White/HERO3 Silver t gpio A5 scripts
GoPro HERO4 Black/Silver Not working, experimental
GoPro Hero4 Session Standard A7 scripts, beware of limited use
GoPro Hero 2014 Standard scripts

How to hack GoPro cameras

You may be thinking, what are these autoexecutables, or why are these codes useful?
GoPro cameras use a Ambarella chip, very often, GoPro refuses to use and include a GUI graphical menu in the firmware some of the resources the chip provides, an example of this: the GoPro HERO3/3+ use A7 chip from ambarella, this chip supports long exposure pictures. Here is an autoexec.ash that enables HERO3/3+ cameras to shoot long exposures.
These commands are obtained via a firmware reverse engineering research or via linux scripting.
For user's facilities, I made a git repository with autoexecutable hacks for different GoPro camera models, most popular are the long exposure hack for the HERO3/3+ and the MegaLapse hack that allows GoPros to take long intervals for timelapse.

Visit AutoexecHack repo

The commands inside autoexec.ash, the file you put in the SD card for the GoPro to execute on start up are written in Ambarella Shell, ASH. The Ambarella Shell language is based on Linux, as it supports mv, cp and it has lu_util exec, a utility to execute commands in the GoPro's Linux side.

GoPro's WiFi API

GoPro cameras happen to have wifi connectivity to control, view and share content with your smartphone and tablet using the official app. Thanks to reverse engineering efforts there's now a unofficial user maintained API for GoPro cameras. Here is my Wifi research, part of it from the guys @ GPforum!. From that list some tech savvy people made apps.
The API calls are in GET, HERO3, 2 and 3+ use a different API structure than HERO4 and 5.
In order to get a livestream from your GoPro camera use this python tool.
