FunGen v1.0.0

[ack00gar]

Summary

Major release. 128 commits, +22k / -14k lines across 222 files. Highlights:

• Installer rewrite: miniconda is gone, replaced by uv + venv. One-shim install, GPU auto-detect across cuda_blackwell / cuda_stable / cuda_legacy / mps / rocm / cpu. ffmpeg + mpv auto-installed via OS package manager.
• Video backend: pyav out, FFmpeg subprocess + libmpv GL render in. New 1 GB byte-budgeted nav cache, anticipatory prefetcher, scrub cache, progressive arrow-hold playback.
• VR dewarp shader: runtime-compiled GLSL with adaptive supersample replaces CPU v360 for in-GUI playback.
• GUI perf sweep: timeline draw, oscillation grid vectorized, plugin algorithms (Resample 8.4x, Keyframes 5.2x, Dynamic Amplify 3.1x), async tracker lifecycle, cached u32 colors throughout.
• Animated splash with 17 themes: random per launch, pinnable via FUNGEN_SPLASH_THEME=<name>.
• New tracker: Cock Hero Beat Tracker (offline audio-beat funscript generator).
• Models: bumped to YOLO26 nano fine-tuned (release models-v2.0.0) -- smaller (5.4 MB vs 18.9 MB), faster, ONNX export added.
• --watch actually processes videos (was dropping queue items into a no-op loop).
• Internal restructure: app_logic split into 8 lifecycle modules; video display split; gui components reorganized.
• Tests: 23 focused unit tests + 1 E2E smoke restored. CI runs them on Ubuntu + macOS.

Conflicts to resolve at merge

Six fix commits on main (gamepad invert, digit-key snap, delete-key, gamepad center, axis cache invalidation, pyGLFW shape) duplicate fixes that already landed on this branch. Accept "ours" -- the release-branch version of each fix is correct.

One main-only commit (3c6571a "fix: pyav decoder skips corrupt packets") targets video/frame_source/pyav_source.py, which this branch deleted entirely. Accept "ours" / keep deleted.

Merge strategy

Regular merge commit (gh pr merge --merge), not squash. Preserves the 128 well-written commit messages for git blame / git bisect.

Test plan

• CI green on ubuntu + macos
• Fresh install on macOS: curl ... | bash -> ./launch.command
• Fresh install on Windows: install.bat double-click -> launch.bat
• CLI batch on a sample VR clip produces a .funscript
• CLI --watch processes queued videos (issue #regression check)
• GUI: open project, scrub, place point, save funscript
• GUI: 8K SBS VR clip with shader dewarp -- known soft issue, may be choppy
• Plugins: dynamic_amplify, keyframe, resample, speed_limiter run on sample script
• Updater: in-app updater shows v1.0.0 -> latest after release

Known issues to call out in release notes

• Shader dewarp on 8K VR is choppy in some configs (open soft issue).
• Two recent reverts (embedded fullscreen in shader mode, F11 routing) -- final state intentional.
