Related project for high-throughput animated QR transfer

[infrost]

Hi! Thanks for building txqr — it is a very interesting project.

I’m leaving this as a reference for people who arrive here looking for newer implementations of high-throughput QR-based offline transfer.

I’ve been working on a related project here:

RaptorQR

RaptorQR uses the Rust cberner/raptorq implementation of RaptorQ (RFC 6330), compiled to WASM, as its primary fountain-code codec.

Measured examples:

Scenario	Result
V20 QR, 4-code parallel playback, 30 FPS	up to 300 decoded QR symbols/s
V30 QR, 4-code parallel playback, 30 FPS	100+ decoded QR symbols/s
95.2 KB file transfer, V30-L x 4QR @ 30 FPS	375 ms, about 254.0 KB/s
6.5 MB file transfer, V30-L x 4QR @ 30 FPS	36 s, about 183.6 KB/s

The 95.2 KB and 6.5 MB file transfer tests were measured using an iPhone 16 / Safari as the QR scanner.

This is not an official continuation of txqr, but I hope it may be useful for people interested in high-throughput animated QR transfer, air-gapped file transfer, or browser-based offline data transfer.

Thanks again for the original work.
