I have ported the 12Mbps mod and my file deletion script fix to the latest ITB100HD 2.2 firmware. This is NOT for the SP model (SP version by dashingthrusnow here).
This version allows the bitrate to be customized by creating a bitrate.txt file within the Setup folder, and typing the desired bitrate into the file eg: 8000000 for 8Mbps, 10000000 for 10Mbps etc. You don't need to create this file if you just want to use the default 12Mbps.
The highest bitrate possible before the camera stops booting is 16000000. This requires changing the freespace check to 180mb (post 15). Note: the camera gets very hot running at this setting, I would not recommend it. I normally run it at 14Mbps.
My script builds an index.txt file within the Setup folder as the video files are written, and uses that file to find and delete the oldest file(s), when the free disk space falls below 150mb, fixing the beeping issue that arises when the SD card becomes full. Also, my script will delete the oldest video files regardless of the event, parking and normal video recording ratios set by the PC Player software.
Installation instructions:
If your camera is already running your desired firmware version (2.2 or 2.1) skip to step 5.
1) Download either v2.2 firmware from here:
http://ipassmall.co.kr/ipassblack/down_proc.asp?filename=itb100hdfw(ver.2.2).zip
Or v2.1 firmware from here:
http://dashcamtalk.com/cams/itb-100hd/Itronics ITB-100HD Firmware v2.1.zip
2) Format the SD card, and extract the itb100hdfw.bin file onto the SD card and insert it into the device.
3) Ensure you have a STABLE power source (e.g. make sure the car is running) before plugging the cable into the CAMERA.
4) Wait until the normal camera startup chime sounds ( ~30sec after the extended beeping during the flashing process) and power down the device.
5) Download all 3 parts of the appropriate attached files for your firmware version (2.1, 2.2, 2.1MPH or 2.2MPH (post 15) - Using yakhack's mod), and extract the contents into one folder.
6) Windows: Run the combiner-win.bat file to combine the files.
Mac/Linux: Run the combiner.sh file to combine the files.
7) Repeat steps 2, 3 and 4.
8) Check that the camera is recording properly and that an index.txt file now exists under the Setup folder. Your device is now running the 12Mbps mod.
9) To use the latest script version, extract the itb100hdfw.bin from the update_script.zip file (or the 180mb_spacecheck.zip file in post 15 if you want to use that) to the SD card and repeat steps 3 and 4. There will now always be a safe.txt file under the Setup folder.
Changelog:
5/2/14: Moved index.txt to Setup folder.
Performed minor optimizations to deletion script.
28/2/14: Rewrote shutdown recovery portions of the script - now there is less chance for a file to not be added to the index if the power is removed just as a video file is being created. There will always be a safe.txt file in the setup folder now (to hold the video name if the script doesn't process it in time before shutdown).
