+# DaVinci Resolve in distrobox
+
+Two images built from the same `Dockerfile`, pushed to a private registry,
+used via distrobox:
+
+- `davinci-amd` — DaVinci Resolve + ROCm + Intel `intel-compute-runtime`,
+  for AMD/Intel GPUs
+- `davinci-nvidia` — DaVinci Resolve only; the NVIDIA driver/toolchain is
+  provided by the host
+
+Registry: `docker.slambin.fr`. Files: `Dockerfile`, `davinci-dependencies`
+(package list), `davinci-run` (in-image launcher).
+
+This setup is a direct adaptation of
+[zelikos/davincibox](https://github.com/zelikos/davincibox) — same base
+image, same dependency list, same install flags — with one change: Resolve
+is baked into the image at build time instead of being installed into the
+box afterwards, to match this repo's "build once, push" convention. See
+`CLAUDE.md` for what was changed and why.
+
+Both `amd` and `nvidia` targets have been build-tested end to end (Docker
+Desktop/WSL2, real `DaVinci_Resolve_21.1_Linux.run`) — dependency install,
+the silent Resolve install, and the patchelf fix all completed cleanly, and
+`ldd` on the installed binary shows no missing libraries. Not yet tested:
+an actual `distrobox create` + GUI launch on real Linux/GPU hardware (see
+`CLAUDE.md` for the full breakdown).
+
+> DaVinci Resolve binaries get baked into these images from your own
+> Blackmagic Design download. Keep the registry **private** — never push
+> these images publicly. Not affiliated with Blackmagic Design.

+
+## Prerequisites
+
+- The DaVinci Resolve (or DaVinci Resolve Studio) Linux `.run` installer
+  from [Blackmagic's site](https://www.blackmagicdesign.com/products/davinciresolve),
+  unzipped, placed next to the `Dockerfile` (the download is a `.zip`
+  containing the `.run` — `unzip DaVinci_Resolve_*_Linux.zip` first).
+- Your host user should be in the `render` and `video` groups for GPU
+  device access: `sudo usermod -aG render,video "$USER"` (log out/in after).
+- NVIDIA only: [NVIDIA Container Toolkit](https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/latest/install-guide.html)
+  installed on the host (see "NVIDIA gotcha" below).
+
+## Build & push
+
+```bash
+REGISTRY=docker.slambin.fr
+VERSION=21.1
+INSTALLER=DaVinci_Resolve_21.1_Linux.run
+
+for target in amd nvidia; do
+    podman build -f Dockerfile \
+      --build-arg "RESOLVE_INSTALLER=${INSTALLER}" \
+      --target "${target}" \
+      -t "${REGISTRY}/davinci-${target}:${VERSION}" \
+      -t "${REGISTRY}/davinci-${target}:latest" .
+    podman push "${REGISTRY}/davinci-${target}:${VERSION}"
+    podman push "${REGISTRY}/davinci-${target}:latest"
+done
+```
+
+## Install / run
+
+```bash
+# AMD / Intel
+distrobox create \
+  --name davinci \
+  --image docker.slambin.fr/davinci-amd:latest \
+  --additional-flags "--hostname davinci-resolve"
+
+# NVIDIA (see gotcha below re: --nvidia vs CDI)
+distrobox create \
+  --name davinci \
+  --image docker.slambin.fr/davinci-nvidia:latest \
+  --nvidia \
+  --additional-flags "--hostname davinci-resolve"
+```
+
+Then:
+
+```bash
+distrobox enter davinci
+davinci-run
+```
+
+### NVIDIA gotcha (unverified)
+
+Houdini's NVIDIA variant just needs `distrobox --nvidia` (host driver files
+bind-mounted, enough for GL/Vulkan viewport rendering). DaVinci Resolve
+needs full CUDA/OpenCL/NVENC, and upstream davincibox's README documents
+using the **NVIDIA Container Toolkit + CDI** route instead:
+
+```bash
+distrobox create \
+  --name davinci \
+  --image docker.slambin.fr/davinci-nvidia:latest \
+  --additional-flags "--device nvidia.com/gpu=all"
+```
+
+which requires `nvidia-container-toolkit` set up on the host (already the
+case on Universal Blue images; see NVIDIA's own install guide otherwise).
+Whether plain `--nvidia` is actually enough has not been tested here — try
+it first since it's simpler, fall back to the CDI form above if Resolve
+reports something like "Unsupported GPU processing mode" on launch.
+
+## App menu entry (icon, no terminal)
+
+Resolve ships its own `.desktop` files and icons under
+`/opt/resolve/share` and `/opt/resolve/graphics` — no need to write one by
+hand:
+
+```bash
+distrobox enter davinci
+mkdir -p ~/.local/share/applications
+cp /opt/resolve/share/*.desktop ~/.local/share/applications
+rm ~/.local/share/applications/DaVinciResolveInstaller.desktop
+sed -i 's/RESOLVE_INSTALL_LOCATION/\/opt\/resolve/' \
+    ~/.local/share/applications/{blackmagicraw*,DaVinci*}.desktop
+sed -i "s,Exec=,Exec=distrobox enter -n davinci -- /usr/local/bin/davinci-run ," \
+    ~/.local/share/applications/{blackmagicraw*,DaVinci*}.desktop
+distrobox-export --app "$HOME/.local/share/applications/DaVinciResolve.desktop"
+```
+

+
+## Known gotchas (from upstream, not yet hit here ourselves)
+
+- **No audio**: Resolve uses ALSA via the `pipewire-alsa` plugin baked into
+  the image. If your host doesn't run PipeWire, swap it inside the box:
+  `sudo dnf remove pipewire-alsa && sudo dnf install alsa-plugins-pulseaudio`.
+- **Codecs**: the free version's codec support is limited — this is a
+  Blackmagic licensing limitation, not something this image can fix.
+- **Studio + USB dongle**: needs a udev rule on the host to let the
+  container see the license dongle. See
+  [davincibox's README](https://github.com/zelikos/davincibox#davinci-resolve-studio-crashes-on-checking-licences)
+  if you hit "Checking Licences..." crashes.
