Tolle arbeit! So the 0803 uses A7, and the hero3 black too. But... The help and t are the same, but t app is the same as GoPro HERO2?? (the previous A5 camera!)
So, to record 30 secs I think its
Code:
t gpio 43 sw out0
sleep 30
t gpio 43 sw out1
t gpio 43 sw out0

Could you explain me what features does the 0803 have (res, modes, fov, etc...) Then I will explain you t ia2 and t cal

a7patcher.png

A7Tool beta (not verified with hardware) 0.2 is out. Added the firmware patcher.
Patches are binary(ok, they are hex) description files of what they should change in a specific partition. This gives you the possibility to add only those features to your Firmware you really want.

How to create them:
This is how a .ap (ambarella patch) file should look like:
Code:
;device
;fw version
;variant
;section
;description
;creator
offset:payload
offset:payload
offset:payload
....
Offset is the position where the replace process should start
Payload is the hexstring which should be inserted (for example higher Bitrate)

IT WORKS WITH HERO3 BLACK FW!
 
1dFCwXi.png

AND AS FAR AS I CAN TELL IT WORKS WITH THE HERO3 BLACK STRINGS.BIN!
 
You are not using the latest v ersion (0.6) :p
 
So, to record 30 secs I think its
Code:
t gpio 43 sw out0
sleep 30
t gpio 43 sw out1
t gpio 43 sw out0
Hm this does not work. I guess GPIO usage is different
 
How to change A7 bitrates:
Section: PRI
Compressed: No

VB rates are stored in arrays which include 4 values: Bitrate(float), unknown(float), unknown(float) and unknown(probably integer or byte)

a7-bitrate.PNG


Example (yellow line):
1. value: 18.0
2. value: 0.75
3. value: 1.125
4. value: 3 (a flag or something like this?)

ok, thanks. Please watch this instructional video: https://vimeo.com/m/91791285
imagine the hero3 as a 0803 cam.
then install this on the SD as shown in the video: https://github.com/KonradIT/autoexechack/blob/GoPro/Video-Effects/Negative/Hero3Black/autoexec.ash

then insert card, turn on camera wait 3 secs and start a video, then tell me how the video looks.
 
Works :D
Negative video.
Is it possible to rotate the image (180 degrees)
 
hahaha that was a compilation of all the video effects, btw why you want to rotate the video 180 º?
Ok, we could make an agreement:
I made this repo: https://github.com/KonradIT/mini0803
I will post hacks there, autoexec.ash hacks, you test them and send me video.
I post on vimeo the video and me and/or you make a page in chernowii.com/mini0803 or in dc.p-mc.eu about hacking the mini0803 camera with the repo and video samples.
I give you full credit.
You can push to the github repo the hacks you make.
Also, does that camera include photo mode? Does it include timelapse mode (take a pic every X seconds)?
Sorry for many questions.
 
Yeah we can do this. I think I'll just use the github API to "mirror" the latest commits on my page :D

180° rotation is not important for me but probably for the guys driving on the wrong side. They have to mount the dashcam in a different way.

It has a "photo mode" but thats useleass since the reason I have a dashcam in my car is ot record while I'm driving :D
