* New collapsible pane sits between the main split and the footer and shows per-core CPU utilisation as btop-style vertical bars. Polls /proc/stat once a second, paints with the live Omarchy accent colour via Cairo. Collapsed/expanded state persists in ~/.config/nocoder/config.json as cpu_pane_expanded (default true) so the pane reopens however the user last left it. * Footer "complete" state now reports TOTAL TIME alongside Succeeded / Failed / Output size. Wall time captured via time.monotonic() when the encode worker starts and again when the state flips to complete; only successful (non-cancelled) batches get a time. Formatted via the existing data.format_duration helper so it matches the pre-encode estimate's display. The /proc/stat parser lives in its own pure-Python module (nocoder/cpu_sampler.py) so it's GTK-free and easy to test in isolation. SystemPane mirrors the Footer attachment pattern (Gtk.Box subclass + __gtype_name__ + add_css_class), attached from MainWindow exactly like the footer is. Timer auto-stops on widget detach via a get_root() check, so no explicit teardown wiring is needed. CSS gets a .system-pane block (top border + padding) and a .cpu-bar-area rule that sets foreground colour to @accent — the Cairo draw callback reads that via widget.get_color() so the bars track the live theme without re-plumbing. Verified: * CpuSampler reports 32 cores at idle baseline; under stress-ng --cpu 0 aggregate hit 99.9% with all bars saturated. * Theme accent cascades correctly; bars use the active Omarchy theme. * cpu_pane_expanded round-trips (manually setting false then relaunching reopens the pane collapsed). * TOTAL TIME shows 0:02 for a 2.28s encode of a 3-second HEVC test clip. * Installed copy at ~/.local/share/nocoder/ updated and verified via the walker launcher.

# NO-CODER
|
||
|
||
A native GTK4 + libadwaita batch transcoder for Omarchy. Drop video files (or whole camera cards) onto the window, choose a ProRes profile, hit Encode. Output is editorial-ready Apple ProRes `.mov` ready for DaVinci Resolve, Premiere, FCP, Avid.
|
||
|
||
## Features
|
||
|
||
- **Real ffmpeg encode** — `prores_ks` (with fallback to plain `prores`), live progress bar parsed from `-progress pipe:1`, cancelable, serial queue with disk-space pre-check.
|
||
- **GPU decode auto-probe** — installer tests `cuda` → `qsv` → `vaapi` and pins the working one to `~/.config/nocoder/config.json`. ProRes encoding stays on CPU (no vendor ships a GPU ProRes encoder), but offloading the *decode* side cuts wall time by 25-40% on H.264 / HEVC / AV1 sources.
|
||
- **Theme-aware** — palette tracks the active Omarchy theme on every launch (parses `colors.toml` / `ghostty.conf` / `alacritty.toml` / `kitty.conf` in priority order). 34 stock + custom themes verified.
|
||
- **Pro camera ready** — `.MXF` from Canon XF / Sony XDCAM / Panasonic AVC-Intra, with proxy-directory pruning so dropping a Sony XAVC card maps only the masters in `CLIP/` and not the low-res duplicates in `SUB/`.
|
||
- **Multi-track audio preserved** — Canon C300/C500 records 4 mono PCM streams; all four land in the output `.mov` as separate tracks. Optional 24-bit toggle for pro delivery.
|
||
- **Live encode-speed indicator** — footer shows real `1.5×` throughput from ffmpeg and refines the ETA from actual measured rate, not a fixed heuristic. After the batch finishes, the footer also reports total wall time alongside succeeded / failed / output size.
|
||
- **Per-core CPU visualizer** — collapsible btop-style pane between the queue and the footer, polling `/proc/stat` once a second and painting one vertical bar per logical core in the live theme accent. Useful for seeing at a glance whether the chosen profile / hwaccel combo is saturating the box or leaving headroom. Expand/collapse state persists across launches.
|
||
- **Hyprland-aware install** — registers a `.desktop` entry with the walker, installs the icon at six hicolor sizes, appends a windowrule that floats and centres the app at 1280×880.
|
||
|
||
## Supported source formats
|
||
|
||
`.mov` `.mp4` `.m4v` `.mkv` `.avi` `.mts` `.m2ts` `.webm` `.mpeg` `.mpg` `.3gp` `.3g2` `.mxf`
|
||
|
||
**Not supported** (proprietary RAW; ffmpeg has no decoder without vendor SDKs): `.crm` (Canon Cinema RAW Light), `.braw` (Blackmagic), `.r3d` (RED), `.ari` (Arri). Pre-transcode those via Canon Cinema RAW Development / Blackmagic RAW Player / REDCINE-X / ARRI Meta Extract first, then bring the resulting MXF or MOV into NO-CODER.
|
||
|
||
## Install
|
||
|
||
Targets Arch / Omarchy specifically.
|
||
|
||
```sh
|
||
git clone https://git.no-signal.uk/nosignal/nocoder.git
|
||
cd nocoder
|
||
bash install.sh
|
||
```
|
||
|
||
The installer:
|
||
|
||
1. Verifies pacman is present, fails fast otherwise.
|
||
2. Installs missing pacman packages: `python python-gobject gtk4 libadwaita ffmpeg`.
|
||
3. Installs Inter and JetBrains Mono fonts to `~/.local/share/fonts/` (per-user, no sudo).
|
||
4. Probes GPU decode and pins the working backend to `~/.config/nocoder/config.json`.
|
||
5. Copies the source tree to `~/.local/share/nocoder/` so you can delete this clone afterward.
|
||
6. Writes a launcher to `~/.local/bin/nocoder`.
|
||
7. Drops the `.desktop` file and PNG icons into the right XDG locations.
|
||
8. Appends Hyprland windowrules (float, centre, 1280×880) inside a marked block in `~/.config/hypr/windows.conf`.
|
||
9. Restarts walker so the entry appears immediately.
|
||
|
||
After install, **Super+Space → "no"** launches it. Or `nocoder` from a shell.
|
||
|
||
## Updating
|
||
|
||
```sh
|
||
cd nocoder
|
||
git pull
|
||
bash install.sh
|
||
```
|
||
|
||
Re-running the installer wipes and re-copies the live install dir — files removed upstream propagate cleanly.
|
||
|
||
## Uninstall
|
||
|
||
```sh
|
||
bash uninstall.sh
|
||
```
|
||
|
||
Removes the installed app tree, launcher, desktop entry, all six icon sizes, the Hyprland windowrules block, and the per-user config. Pacman packages and fonts are left in place (other apps may need them).
|
||
|
||
## Hardware
|
||
|
||
- **Required:** anything that runs Omarchy / Hyprland.
|
||
- **Recommended:** a GPU with ffmpeg-supported decode (NVIDIA NVDEC, Intel QSV, AMD VAAPI). The probe falls back to CPU decode on systems without; everything still works, just slower on camera-native sources.
|
||
- **No upper limit on cores** — `prores_ks` is well-parallelised.
|
||
|
||
## Configuration
|
||
|
||
`~/.config/nocoder/config.json` is read at launch and merged on every settings change. All keys are optional:
|
||
|
||
```json
|
||
{
|
||
"hwaccel": "cuda" | "qsv" | "vaapi" | "none",
|
||
"profile": "proxy" | "lt" | "standard" | "hq" | "4444" | "4444xq",
|
||
"naming": "keep" | "suffix",
|
||
"out_dir": "/absolute/path/to/output/folder",
|
||
"audio_bits": 16 | 24,
|
||
"auto_reveal": true | false,
|
||
"cpu_pane_expanded": true | false
|
||
}
|
||
```
|
||
|
||
You can edit by hand to override the auto-probed `hwaccel` or to seed defaults; everything else just reflects what you've picked in the UI most recently.
|
||
|
||
## Known gaps
|
||
|
||
- "Reveal in Files" opens the output folder but doesn't *select* the specific file.
|
||
- Per-row remove button isn't keyboard-accessible (mouse-hover only, by design — keeps tab order clean).
|
||
- No live theme-change pickup — theme swaps apply on next launch, not immediately.
|
||
|
||
## License
|
||
|
||
Not yet specified. The app wraps `ffmpeg` and depends on GTK4 / libadwaita; check those licenses for the redistributable parts.
|
||
|
||
## Credits
|
||
|
||
Born as a rewrite of `prowrap-yad.sh` (a yad-based ProRes batch transcoder), rebranded NO-CODER to lean into the visual identity. The encoding logic from the original bash script is preserved verbatim.
