Guys, new firmware up and ready.

The release add 2 ways of launching scripts at Yi start up.
With a script called "bootcmd.sh" on the root of the SDCard.
This script could be used to launch commands directly on the Linux OS.
With a script called "events_boot.py" in the folder events.
This script permit launch of events at boot to RTOS.

More over, custom firmwares have now a custom version number starting at 1.10.50.

Please, I would like some feedbacks on what you are doing with this firmware.

@jcallows, I will provide you a script in the next days (or hours or minutes maybe...)

@jcallows, after upgrading your firmware to 1.10.50.
  • Copy the following code in a file called bootcmd.sh.
  • Copy the file in the root of your SDCard and boot your Yi.
Code is self explained.
It is better to use Notepad++ on windows to copy the code. Change EOL conversion to Unix.

Your cam should be in video mode otherwise a photo is taken instead of a video each time SendToRTOS record is fired.
Code:
#!/bin/sh

# Count number of time the block of commands is run DO NOT EDIT
n=0
# Maximum number of time the block of commands is run (-1 = infinite loop) EDIT
max=-1
# Wait for XXs before the block of commands is run EDIT
sleep 5

while [[ $n -ne $max ]]; do
  # First command
  /usr/bin/SendToRTOS record
  # Wait XXs before the next command is run EDIT
  sleep 30
  # Second command
  /usr/bin/SendToRTOS record
  # Wait XXs before the next command is run (1rst command) EDIT
  sleep 10
  let n+=1
done

Sorry for the noobie questions but I've spent the last hour reading Git, searching YouTube, and this forum, not seeing answers to these. I'm coming from GoPro Session5 and Hero4 so hoping this is a large step up for Mtn Biking and Skiing.

Questions:
-- Where do I download 1.10.50 firmware BIN?
-- Is 4k resolution a large improvement in Image Quality over 2.7K or 1080p at higher bit rates?
-- What resolution and bit rates give you the best quality with EIS?
-- any other advice?

thx for the help!

Hey,

I don't know for popular res/fps.
BTW, I have an other thread where I write about autoexec.ash file. You will find answers to your questions.
https://dashcamtalk.com/forum/index.php?posts/439161

I am also finishing a web page for automatic creation of this file for bitrates customization (main and live)
I will certainly add all possible commands.

Wait till the end of the week.

@stelloy, do know either.

Excellent! one idea might be to have something on the web page that records how many times people create specific settings, or have some way to capture and show the most popular settings people create or allow them to vote showing what settings they use. This might help the larger community know which settings work best and for what situations.

Hello, not sure if you're still developing on this firmware but could you add a way to set a custom shutter speed in video mode instead of auto?

Hello,

I am still reverse engineering the firmware.
I am on lots of different finding.
I will add this to my Todo list.
