VDWT v0.1.0-beta.2 (open source)

VDWT is now open source. The full source is in this repository, under your choice of the AGPL-3.0 or the PolyForm Small Business License 1.0.0 (free for companies under 100 people and 1M USD revenue, closed-source products included), or a commercial license (vdwt@proton.me). These binaries are built from this tag.

Unpack and run ./vdwt selftest (vdwt.exe selftest on Windows). Inputs other than .y4m need ffmpeg on the PATH. Checksums are in SHA256SUMS.txt.

Changes since beta.1

• Source code published, with CONTRIBUTING.md and a Contributor License Agreement (CLA.md).
• ARM64 build fixed for older cores: beta.1's ARM64 binary used ARMv8.2 instructions and could crash ("illegal instruction") on Cortex-A53/A57/A72 boards such as the Raspberry Pi 3/4 and Jetson Nano. This build targets generic ARMv8-A.
• The codec and the bitstream are unchanged: streams from beta.1 decode identically.

The side-by-side comparison videos are attached to v0.1.0-beta.1.

Beta: the bitstream format may still change between beta versions. 8-bit 4:2:0 only; raw .vdwt streams (no MP4/MKV mapping yet); video only.

VDWT v0.1.0-beta.1

Warning

Superseded by v0.1.0-beta.2. This release's ARM64 binary uses ARMv8.2 instructions and can crash on Cortex-A53/A57/A72 boards (Raspberry Pi 3/4, Jetson Nano). Use beta.2.

First public beta of VDWT, a hardware-aware, fully parallel, block-free wavelet video codec.

Side-by-side videos (left VDWT ultraheavy, right Intel hardware HEVC, 1080p60, near-lossless x264 of both decodes): motocross FPV at 600 kbit/s and 1 Mbit/s, bike ride at 731 kbit/s (equal rate) and 1 Mbit/s. Footage from Pexels: "Motocross FPV drone" by Eno Eltora and "Bike" by Adrián Vizuete Moreno.

Free for personal, hobby, research and educational use (PolyForm Noncommercial 1.0.0) and for companies under 100 people and 1M USD revenue, closed-source products included (PolyForm Small Business 1.0.0). Any company may evaluate VDWT internally for 90 days at no cost; larger companies need a commercial license after that: vdwt@proton.me. Each archive contains the license texts. The source code will be open-sourced soon, under your choice of AGPL-3.0 or PolyForm Small Business, or a commercial license.
