#GoPro HERO4 (A tale of firmware leaks and marketing)

Written by /u/konrad-iturbe (Konrad Iturbe) and with help of /u/OverByThere's leaked firmware.


The GoPro HERO4 Black Adventure edition is 4x times more powerful than ever.

HERO4 cameras:

  • HERO4 Black (BANZAI)
  • HERO4 Silver (HAWII)

FEATURES (black only, silver is like a shitty hero3+ black):

  • port c:/ is SD
  • port C:/ is camera internal storage
  • BANZAI codname
  • Update path is c:/update/camera_firmware.bin [NOTE: Ambarella A9 chip does not read the update like traditional HDX-firmware.bin and WFX-app.bin and the other files]
  • autoexec.ash still exists, so like in the hero3 / hero3+ the hero4 may have all the features, but not shown in the GUI menu. With autoexec.ash is easy to unleash those features like in previous cameras.
  • Ambarella A9 chip like suggested in rumors all across the net
  • GPS, Environmental data logging (temperature, humidity, etc...)
  • Same resolutions as in the HERO3+ black Misleading data
  • Compatible with bacpacs New bacpacs (marketing!), and compatible with the HERO dual 3d system (probably same HERO3+ case)
  • Full integration with 3D HERO bacpac
  • LCD bacpac commands (seems the bacpac comes with the camera)
  • Connection to external wifi (for uploading media to a GoPro site and from there to social media)
  • New value in protune: Native WB
  • new modes: Multi shot and quick capture
  • Photo mode now have a "photo settings" section in the settings (seems photo has more parameters than just the resolution setting)
  • The GoPro HERO4 star feature: Multi shot, a dynamic burst that shoots pictures with more imaging settings
  • Show the camera info in the settings or in LCD bacpac touch
  • No WVGA 480... Misleading data
  • Night mode for pictures
  • Same pic res as HERO3+black
  • Same protune settings as HERO3+Black
  • LCD sleep (such as in smartphones)
  • Network and smart wifi settings
  • BLUETOOTH!!!
  • Streaming to the internet using secondary GOPs (http://en.wikipedia.org/wiki/Group_of_pictures)
  • IDR streaming (http://www.streaminglearningcenter.com/articles/everything-you-ever-wanted-to-know-about-idr-frames-but-were-afraid-to-ask.html)
  • Protune shutter exp (2s, 5s, 10s, 15s, 20s, 30s)
  • Submodes, new modes that merge different modes (submodes available: photo, multishot, video and quick capture)
  • NightLapse, night timelapses made easy
  • NightLapse has intervals from 15s to 60m
  • uCode with orccode binary loaded on SD
  • Ambarella ImgProc lib (Image processing) (http://docs.opencv.org/doc/tutorials/imgproc/table_of_content_imgproc/table_of_content_imgproc.html) /Supports 3A/

##RESOLUTIONS:

Here, data is misleading, the settings.json says that these are the resolutions:

  • WVGA 240
  • 720p 120
  • 720p SuperView 120
  • 960p 90 100
  • 1080p 60 80
  • 1080p SuperView 60 80
  • 1440p 48 50
  • 2.7K 24 25 30
  • 4K 12.5 12 15

###Rumors NO/Yes

#####DGISE:

"First of all GoPro Hero is a compact, rugged, lightweight (less than 100 grams) action camera with a special attachment for anything (boards, kiteboarding, surfing, windsurfing, helmets, ski poles, cars, bikes, BMXs and other that can be in motion). Everyone will be able to enjoy hours of video about your achievements and exciting emotions in 4K quality. YES

GoPro Hero 4 is really capable of recording video in 4K resolution at a speed of 30 frames per second YES, 1080p at 120fps YES and 720p at 240fps YES, which became possible with the advent of the new SoC Ambarella A9 chip (dual A9 ARM Core ® CortexTM-A9 processor 1GHz with FPU accelerator) YES for advanced applications, wireless connection YES and streaming video in social media YES.

GoPro Hero 4 will also come with a 13-megapixel photosensor NO and a completely new lens for shooting in dark YES. Multi-Exposure YES and HDR WDR tone mapping NO, electronic image stabilization YES, also improved MCTF NO. Dual sensor interfaces 12-lane SLVDS/HiSPiTM/subLVDS NO, 4-lane NO, remote viewfinder playback which is extremely easy to use NO. You shouldn’t to have special technical knowledge or skills to do it. GoPro Hero cameras are amazing because they have a waterproof housing with a flat lens for shooting under water (up to 60m). Built-in Wi-Fi module, USB & HDMI - the only thing that brings it closer to homeliness. The camera has the ability to capture still images during video recording and perform encoding H.264/ BP / MP / HP Level 5.1 and MJPEG.

GoPro Hero 4 will hit on shelves in October 2014 YES (?!?!?). Action Cameras of GoPro have become extremely popular as an excellent way to capture high-quality video at high speeds relative to the price that usually is $340."

#####Christian Today (random, more than 10 articles about HERO4 in that page):

Extreme sports enthusiasts and adventure seekers know that nothing beats a GoPro when it comes to recording live-action footage, as the camera is known to perform splendidly whatever the conditions may be. Whether it's attached to the helmet of a baseline jumper, or strapped onto the handlebars of a bike going on rough terrain, it's guaranteed to produce videos with amazing quality.YES This is the reason why fans of the brand are eagerly anticipating the latest version of the camera, the GoPro Hero 4. YES

According to Dgise.com, the GoPro Hero 4 can record in 4k resolution at a speed of 30 frames per second. YES It will also come with a 13-megapixel photo sensor, NO which is a new lens that can enable the user to shoot videos or take pictures in the dark, YES electronic image stabilization, YES and an improved MCTF, NO among others. It will also have WDR tone mapping,YES plus Wi-Fi capabilities with remote viewfinder and playback functions. YES

The new camera will also let the user record videos at a lower resolution, which results in faster video capturing, ideal for extreme sports. And yes, the camera is waterproof. YES

It is also expected to weigh less than 100 grams, ? and because it is an action camera, it includes a unique attachment that can clamp to almost anything such as skateboards, surfboards, ski poles, bikes, cars, and basically anything else that moves. YES

Aside from all these, there are rumors that the Hero 4 will be equipped with two lenses for filming in 3D, but this has not been confirmed. WTF? NO

The GoPro Hero 4 will reportedly be priced at $340 NO and is expected to be launched on October 2014. YES

###DATA FOR DEVS:

Example: C:\Jenkins\workspace\Banzai-Release\BANZAI\app_control\picture\test_pic_capture.c

  • *C:* is the internal camera memory drive, like in windows os
  • Jenkins is a oracle software that acts like a user
  • workspace is the main dir inside Jenkins
  • Banzai-Release is the code name for the HERO4 (Banzai)
  • BANZAI HERO4 codename
  • app-control controls of the camera
  • picture picture dir with lots of .c code

##Reddit and leaked info

User on reddit, who is a sport shop employee (not given any personal data to protect privacy) posted a picture clearly seen camera model, new bacpacs and price: picture

Other user wanted to buy a gopro and the shop employee confessed that there was a GoPro HERO4 Black Adventure Edition around the corner.

With the GoPro HERO4 so near shops got the HERO4 camera to stock, and unofficial GoPro company Smartree leaked the sketches of the HERO4. See megathread: http://www.reddit.com/r/gopro/comments/2hg0rm/hero4_megathread/

gopro 4 never supported 3d hero system (unfortunatelly). Please correct that part.
