Ten Dropbox Engineers Build BSD-licensed, Lossless 'Pied Piper' Compression Algorithm

An anonymous reader writes: In Dropbox's "Hack Week" this year, a team of ten engineers built the fantasy Pied Piper algorithm from HBO's Silicon Valley, achieving 13% lossless compression on Mobile-recorded H.264 videos and 22% on arbitrary JPEG files. Their algorithm can return the compressed files to their bit-exact values. According to FastCompany, "Its ability to compress file sizes could actually have tangible, real-world benefits for Dropbox, whose core business is storing files in the cloud."The code is available on GitHub under a BSD license for people interested in advancing the compression or archiving their movie files.

    Meh, doesn't matter. Any processing load will be moved to an unoptimized javascript implementation that runs in the end users browser.

    Can it compress 3d videos? That seems to be a real challenge.

    Compress his comment and all the redundancy will be gone.
