Hi! i just take a look at the firmware 1.23 of the yi 4k, and it seems to have a lot of cool features disabled

as you can see in the image, the syntax seems to be pretty similar to scripts of the older yi... but i've just tried the autoexec.ash and unfortunately doesn't work :(

raw photos: t app test enc stillrawcap [Cmpr][DumpItuner]

raw videos: t app test videorawcap [RawCompress][Number][EnableFaseCapture][EnableYuv]

i'll keep working on it, if someone who knows better ambarella architecture want to join, will be veeeeery apreciate :)

ps: sorry for my english :D

use Cal.txt instead of Autoexec.ash
it tries to run Cal.txt but not sure of the t app test syntax or how to get it to work
 
i've asked directly to xiaoyi about some specs, and they replied that they are still working to a beta firmware with raw photo enabled.. that will be released next year

i'll wait, i'm became too lazy ahahhahaha
 
Nice find Alexdb.

I'm interested in the line mentioning Raw Video,..

Have been looking at action cams and settled on the Yi 4K as most appropriate to put in a gimbal under a model Heli with a Ribcage mod and some other bits an pieces - the sample vision for this camera on gimbals, and with its accelerometer based image correction, is a step ahead of the competition.

Shooting Raw video would be a real bonus to us Cinematographers, if Yi enable it.
Raw at HD or 2K would be fantastic, Raw at 4K, would have some very serious film hardware companies worried.

It would mean needing top end SD cards for the data rates required, but the advantages to guys like me, the Yi4K with Ribcage and a decent C-mount lens, would make a great action 'crash cam' for feature films.
 
Hi,

I would really like to lock the shutter speed for timelapses.. but I can only set it to AUTO or >2 seconds..
The automatic shutter speed setting leads to a flickering in the finished timelapse.
Anybody managed to crack the code? :D

Cheers
 
Autoexec.ash scripts do work with the Yi4K, just not as well as they do for the original Yi

If you create a autoexec.ash file in the root of the sd card and switch on the camera it will execute the commands listed in the file on bootup.
Unfortunately there are not many documented commands and a lot of them either do not work or get overwritten when you use the camera.

So you can set the camera to automatically start recording video as soon as it has booted up by having the following command in the file:

t app key record

this will simule the record key being pressed and the camera will automatically start recording video on startup be careful though because if you are in a photo mode when you switched it off it will go a bit funny.
Another useful one is to start wifi automatically on bootup, this is great for the people that have cracked their lcd screen and cant manually turn the wifi on. The command is:

t app key start_wifi

to turn off wifi, you can use:

t app key stop_wifi

other t app key commands are:

key Usage: t app key <key>

up
up_rel

down_rel

If you edit any of the firmware.bin files you can sift through the entire file and find references, here are some I have pulled out.
I have tried a few and they either dont work or crash the camera, but here you go have a play and report back here if you get any luck :D

I've tried the wifi command in firmware 1.4.14, and the camera freezed, need to pull out the battery.
Code: 
t app key start_wifi
or
t app key stop_wifi

But this script works:
Code: 
#start or stop wifi
sleep 5
#t ipc rpc clnt exec1 '/usr/local/share/script/wifi_xy_stop.sh'
t ipc rpc clnt exec1 '/usr/local/share/script/wifi_xy_start.sh'
 
Is there a way to test executing commands while the camera is running via telnet?
