vtome 0.3.5

Show images and video on a specific monitor — or a specific quadrilateral of one — with royalty-free codecs and no FFmpeg. GPU presentation with perspective-correct corner pinning, optional windowing, and a frame pipeline that stays in YUV until the shader.

# vtome's Linux test image, Debian family: `BASE=debian:bookworm` or
# `BASE=ubuntu:24.04`. Built and run by docker/run.sh.
#
# Everything the default toolkit and its feature matrix need from the system,
# and the converters that make the test fixtures:
#
#   - a Rust toolchain and a C toolchain
#   - ffmpeg (with x264, AAC, MP3, Opus) and python3 — the converters. The
#     H.264 fixture is rebuilt with them inside the container, which proves
#     both the image and tests/data/make_h264_fixture.sh
#   - Mesa's software Vulkan (lavapipe), so the GPU tests draw and read back
#     real pixels with no GPU in the container
#   - winit's X11/Wayland headers, and GTK and WebKitGTK for the `tauri`
#     feature — Tauri 2 needs them on Linux even with no webview in use
#   - GStreamer with libav and x264, the system H.264 decoder and encoder
#     vtome opens at run time
#
# The source is mounted read-only at /src and copied, so fixtures made here
# never land in the working tree.
