This code converts a selected file to base64, then chunks up the string based on the specified qr_string_size (Note: the larger the chunk size, the larger you'll need to set the qr_image_size, or you wont be able to read the QR Code). These Chunks are then converted into QR Codes and displayed in the browser and can be played back at a speed specified by the playback_delay setting.
Settings can be configured in scripts/main.js
- Open the index.html page in any browser.
- Select the file you want to process.
- Wait... The code will spit out QRs as they are processed.
- Use the Playback feature to cycle through the QR codes at the desired pace.
Optional params:
base64: Passing a base64 string to this command will auto-start processing the file.
playback: Passing the string finish to this param will auto-play the results, when QR codes finish rendering.
Example: index.html?playback=finish&base64=my_long_base64_string
Big Buck Bunny (5.5mb) takes 6:30 minutes to process with the default settings, but I've gotten it to 3:57 by increasing the chunk size.
