Xiaomi Yi action cam custom scripts.

I'm not affiliated with any action camera brand. Please feel free to contact me if you want to provide me a sample of hardware to get independent expert comments or any other unbiased assessments.

Hi there! I decided to put here all the info I got about hacking Xiaomi Yi cam using autoexec.ash script, telnet-access, customizing firmware and etc. Check my other posts concerning Xiaomi Yi RAW file processing and other nutty stuff.

So now let's talk about autoexec.ash script, I will call this script ASH for short hereinafter.

Xiaomi Yi ASH scripts divide into three groups:
  1. Autorun scripts. They aimed to run once or repeatedly in loop mode. Usage examples: HDR capture, 100% quality JPEG capture, RAW timelapse.
  2. Tuning scripts. Those modify some settings overriding cam defaults allowing it operate in normal modes with improved functionality. Usage examples: Super-HD video, Change video bitrate, Fixed ISO, EV correction, RAW+JPEG still capture, Exposure lock.
  3. System scripts. Linux and RTOS tweaks and undocumented features.
Scripts in general can't damage/brick your device until they don't run any file-system commands. Such commands normally are not needed but I will highlight them in script description if any occurs.

Autorun scripts:

HDR-EXPO-3 - HDR exposure bracketing script (0/-3/+3 EV). Captures 3 JPEG images with 0EV, -3EV and +3EV exposure, Noise Reduction is off, ISO fixed to 100, WB is off before shooting, some  corrections to add details. Beep when ready and before cam off.

HDR6 - HDR script v 2. Captures 6 JPEG images with various shutters, ISO fixed to 100, some Shadows/Highlights clipping correction, Gamma correction. Cricket beep before cam off.

HDR6N - HDR script NIGHT v 3. Captures 6 100% quality JPEG images in LOW_ISO mode with various long shutters, ISO fixed to 400, some Shadows/Highlights clipping correction, Gamma correction. Long beep before cam off. This script deletes all junk .bin .BIN .RAW .TXT .UV .Y files from your 100MEDIA folder. Those file are normally produced by the script and can be deleted.

AUTOREC - AUTO REC. Starts video recording after camera boot. Good for dashcam (Car DVR) use. If this script doesn't run in your cam try this one with boot delay increased to 10 sec.

RAWLAPSE - RAW LAPSE v 2. Timelapse loop capture RAW+JPEG images with 7.9 s exposure and  8 s interval ISO fixed to 100. Will capture until memory is full or battery is empty. To stop capture please turn off the camera. This script deletes all junk .bin .BIN .TXT .UV .Y files from your 100MEDIA folder. Those file are normally produced by the script and can be deleted.

Tuning scripts:

YIMAX-PRO - YiMAX-PRO for Z26 Yi cam with 1.5.6 firmware. This script removes 'watercolor' look and provides the real 'flat' picture for post-production. It sets 1296p30 mode with 40 Mbps ABR (+-25%) bitrate. 1080p60 version. You can find 1.5.6 FW updates for all hardware versions here.

YIMAX-PRO - YiMAX-PRO for Z22 Yi cam with 1.5.6 firmware. This script removes 'watercolor' look and provides the real 'flat' picture for post-production. It sets 1296p30 mode with 40 Mbps ABR (+-25%) bitrate. 1080p60 version. You can find 1.5.6 FW updates for all hardware versions here.

YIMAX-PRO - YiMAX-PRO for 1.2.13 firmware. This script removes 'watercolor' look and provides the real 'flat' picture for post-production. It sets 1296p30 mode with 40 Mbps ABR (+-25%) bitrate. Thanx HiddenPilot for his help. 1080p60 version.

YIMAX-MOVIE - YiMAX-movie for 1.2.0/1.2.6 firmware. Script for video recording mode (raw+jpeg capture supported in photo mode). Sets SuperHD (1296p30@30Mbps) mode. Loads config file to set up sharpness, noise reduction and other filters. Provides "flat" picture with more details in shadows and highlights, reduces "watercolor" effect. Disables aggressive sharpening. Here is 1080p30@30Mbps version of the script. 1080p60@35Mbps modification.


YIMAX-MOVIE - YiMAX-movie for 1.2.10 firmware. Script for video recording mode (raw+jpeg capture supported in photo mode). Sets SuperHD (1296p30@30Mbps) mode. Loads config file to set up sharpness, noise reduction and other filters. Provides "flat" picture with more details in shadows and highlights, reduces "watercolor" effect. Disables aggressive sharpening. Here is 1080p30@30Mbps version of the script. 1080p60@35Mbps modification.

YIMAX-MOVIE - YiMAX-movie for 1.2.13 firmware. Script for video recording mode (raw+jpeg capture supported in photo mode). Sets SuperHD (1296p30@30Mbps) mode. Provides "flat" picture with more details in shadows and highlights, noise reduction is off. 1080p60@35Mbps version1080p30@30Mbps version.

YIMAX - YiMAX. Adds colors and details in shadows and highlights. Reduces noise filter. Enables RAW+JPEG capture for stills and SuperHD (1296p30@30Mbps) mode for videos.

RAWWB - RAW WB. Disables AWB and improves details in highlights. Useful for videos. Use still RAW capture feature from YiMAX script to get unprocessed images. White Balance is set and locked each time you turn the camera on, so if you want to reset it for the new scene just reboot the camera.

WARP-ON - Warp-on script. Activates lens rectification (fisheye correction) function. Useful in cases when you want to enable this feature, but can't connect to your Yi using WiFi.

System scripts:

WIFI-STA - Wireless adapter (station) mode. Made by Andy_S. Connects to existing wifi network. Edit "wpa_supplicant.conf" file in "wifi" folder: change "YourNetworkName" to you actual wifi network name (SSID) and change "YourSuperSecretNetworkPassword" to your network pasword. Please note this script is aimed to work with networks secured with WPA2-PSK. Put files (autoexec.ash and wifi folder with its contents) to the root of microsd card. Turn on the camera and turn on wifi if it's not enabled to autostart wifi. Wait for the beep.

SDTEST - SD card test. Gets info for MicroSD card installed into Yi camera. Check 'cardinfo.txt' file in the root of the card after running.

How to install scripts. Copy autoexec.ash file from the downloaded .zip into root of your MicroSD card. Turn Yi cam on. To uninstall script just remove/rename autoexec.ash file on MicroSD.

USE SCRIPTS AT YOUR OWN RISK! 
THE SCRIPTS ARE PROVIDED "AS IS". ANY MODIFICATIONS OF THESE SCRIPTS CAN RESULT IN DATA LOSS AND DAMAGE YOUR CAMERA!

This post will be always up to date according to any new ASH hacks discovered. Stay tuned!

  1. Hello, I own a Xiaomi Yi and I've noticed an awful noise filter in pictures even with daylight and ISO set to 100. Would it be possible to have a script or a hack to erase or at least reduce that filter in photos? It would be awesome if there were a way to activate it only with high ISO but I guess that is very difficult. I've found a couple of scripts that can erase the filter for videos, but for photos they don't seem to work.

    Thank you for your work and your attention and sorry for my bad english.

    1. Hi! There are 3 modes for still capture: LOW/MID/HIGH ISO and the camera (its RTOS actually) sets them automatically according to shooting conditions. Post-processing settings for each of these modes are very different (f.e. LOW ISO gives pretty crispy picture), but I didn't manage to find out how to switch them manually using a script yet.

    1. Hi!,
      Yes there is a problem with colors. Each RGGB byte needs a value subtraction but still not sure how to do it in a proper way. BTW, raw2dng reduces 14bit raw data to 12bit.

      Git repo? Maybe later :)

  6. Hey Nutsey!
    We need a RAW2DNG converter which produces 16-Bit DNGs (the guys at magic lantern had the RAW2CDNG converter, which supported 16bit output.)
    As to the Values for RGGB, You can easily correct the 12bit DNGs in exiftool. WhiteLevel 1024, Blacklevel 50.
    Here is a convenient script. Just dragndrop all your DNG files into it and they look perfect. I calibrated this only with my eyes and my cam, so your results might vary.

    1. Hm. Time interval is not enough to save RAW+JPEG to memory card. It can be caused by limited writing speed of microsd or cam hardware revision difference. Try to increase "sleep 16" to 17 or 18.

    2. Hey, I tried, I even deactivated the RAW altogether.
      Only the last picture remains on the card. So it always gets overwritten. Also no numbers are missing. My last picture from before is YDXJ0120 - and after 5 minutes timelapse I get just one picture, YDXJ0121 - from the end of the "timelapse".

    1. Calling the "t cal -raw 2 1 0" function inside your loop works fine. using the "t app key shutter" command only takes 1 shot. I modified the script now and it works. :)

    2. Is default camera mode set to photo not video?

    3. does it make any sense switching into photo mode by default?

      Удалить
    4. I can test to find out if that fixes it. But ideally, a script should be independent of the mode I think.

      sadly, t cal raw is a little bit slower with capture.

    5. There is no currently known way to set (not just switch between them) photo/video mode using a script.

  16. Feedback on YiMax-Movie:
    1. coring settings can only be changed after removing the battery, they seem permanent until then
    2. it introduces a sound into the video that sounds like autofocusing of a DSLR. (weird!)
    3. it introduces chromatic aberration at some edges

    which line is the watercolor-reduction?

    ОтветитьУдалить
    Ответы
    1. 1. Coring default is 21-24 depending on video mode.
      2. Maybe it's just wifi on?
      3. Yeah it looks like CA, but it is not CA, it's chroma median filter reduced to some level.

      "Watercolor" or "plastic" look is produced together by several filters, but FIR sharpening has major effect here. So it's "sharpening_fir.fir_strength X" in config file.

      Thanx for your feedback!

    1. The shortest interval between raw stills is limited by the need to dump the captured data to the memory card. So it takes about 6 seconds to do that.

    I guess you've found many commands analasying the firmware, what about the script lamgauge used by the camera and its environment context ?

    2. Yeah :-D
      I would say more, we could use Arduino Yun with a light sensor that sends light levels or ISO values through wifi to the camera. Well actually I dont know which protocol to use to communicate with the camera but being two linux systems it's should be possible somehow :-)
      I can look for Arduino light sensor projects it's should be easy.

      I've just tried Wifi Station script and it works well !!
      great .. I have to understand now how to use the camera web server to get the real time video

    3. Hi Nutsey, I studied a bit in these days and I learned many things but I'm also confused so I hope you can help me with some advise.
      I was happy because with the help of some friend I wrote a script that by using ephemeris was able to change dynamically the ISO and shutter.
      Unfortunately, the script didn't work when moved in the autoexec file. I realized that only a limited number of commands are enabled in the autoexec.
      I found a (not) complete list of them at https://github.com/kerenmac/Xiaomi-Yi/blob/master/Autoexec_commands.txt.
      However there are behaviours I don't get very well. For example in your WiFi Station example in the autoexec you launch a shell script with the command:
      lu_util exec '/tmp/fuse_d/wifi/sta.sh'. Well I tried to launch a script using the same command but it doesn't work.
      Another strange behaviour is with telnet. I logged as you describe and I was able to switch directory and also create a file test.sh in the fuse_d directory
      but if I try to execute (./test.sh) the shell answers "file not found" :-0 !!
      I discovered that the camera comes with many commands from busybox but still confused with the permission that I have within the autoexec and generally if I can launch a "standard" script (.sh) from the autoexec.
      Thanks !

  31. Hi Nutsey, thank you for your scripts they all worked like a charm! I was able to mix and match some of the scripts thanks to your description for each script. Do you know the script for 720p 120fps @ max bitrate? Say 30 or 35mbps? Thanks!

  34. Hi may I know how to edit the interval and the exposure time for rawlapse?
    Provided that I have disabled raw output, which number do I need to change respectively? (E.g. 1 Sec Exposure with 3 Secs Interval)

    Thank you very much

    1. In the HDR6 script there is an example on the how can be changed the exposure from 1 = about 8 seconds to 900 = 0,062 seconds. The ISO can range from 0 automatic ... 100, 200, 400, 800, 1600 as far as I know.
      May be there are other values we can use but I believe it's enough to begin ;-)

    3. In the loop "While do" there is an instruction sleep 16 that delays the next iteration (shot) of 16 seconds.
      You can change that number, but consider that it has to be greater than the exposure (8 sec in the script) and in the case of RawLapse script also the time to save the big RAW file.

      Удалить
    4. @Mauro Furfari THANS FOR REPLAY . Which instruction are you referring to?
      I will set shooter to let set 1/400 for aerial raws but still tont know how to set interval to let say 4s?
      On fast cand that should bo OK

      Удалить
    5. After downloading the RawLApse zip, if you open the autoexec.ash script inside the zip file with an editor ( I suggest an editor linux-compatible that's ending each editing line with a newline character: \n ... for example JEdit ) at the bottom of the code you find:

      #MAIN LOOP thanx VOTerra
      while true
      do
      t app key shutter
      sleep 30 # <---- change this i.e. sleep 4 for 4 seconds
      done

      the number are seconds, I think you can use also decimal values that's half second is sleep 0.5.
      But I don't know how long it will take to process a raw image. So you might increase the interval if it is not enough for the camera to store the raw on the SD card. Just try it.

      Удалить
    6. Thank you @Mauro Furfari. So sleep "X: is for interval however this setting is "16" for 8s interval in the above settings I hope it goes proportionally like with shooter. will have to test. thanks

    5. Class 10 is the standard for action cameras, however you need to check the write speed. It needs to write at least at the number of mbps your camera is recording at. Don't get confused with the read speed that sd card manufacturers put in their specs. Your looking at write speed - plenty of info on the net . Google best sd cards for action cameras and you'll see what I mean.

      Удалить
    6. Also with higher bitrate and fps, your cpu/graphics card are pushed further. Meaning that when you preview the footage, it can seem blurred when its not. It's just the cpu/graphics card struggling to keep up. Test your footage on a high spec computer to see true results . I have gone thru this exact problem. Once it's in your video editing program it should also iron out movement blur.
