vitaImmich

Minimal proof-of-concept Immich client for the PS Vita. It connects to your Immich server and shows your library (photos and videos) as a scrollable chronological grid (newest first), with a full-screen viewer and hardware-accelerated video playback.

Requirements

A PS Vita with HENkaku/h-encore and VitaShell
An Immich server reachable from the Vita's Wi-Fi (recent Immich version — it uses POST /api/search/random and GET /api/assets/{id}/thumbnail)
An Immich API key (web UI → Account Settings → API Keys)

Building

Needs VitaSDK with the libvita2d, curl, openssl, zstd, zlib, libpng, libjpeg-turbo and freetype packages installed (via vdpm).

export VITASDK=$HOME/vitasdk
export PATH=$VITASDK/bin:$PATH
cmake -B build -S .
cmake --build build

This produces build/vitaImmich.vpk.

Installing & configuring

Copy vitaImmich.vpk to the Vita and install it with VitaShell.
Launch it once — it creates ux0:data/vitaimmich/config.txt.
Edit that file (VitaShell → SELECT for FTP makes this easy):
```
server=http://192.168.1.100:2283
apikey=your-immich-api-key
```
If your server sits behind a public domain (reverse proxy) and your router does not support NAT loopback, add the server's LAN IP so the domain is pinned to it while on your home network:
```
server=https://immich.example.com
apikey=your-immich-api-key
serverip=192.168.1.100
```
This keeps the Host header and TLS SNI on the domain (so the reverse proxy still routes correctly) but connects to the LAN IP directly.
Relaunch the app.

Controls

Grid view:

Button	Action
D-pad	Move selection (hold to repeat)
L / R	Jump two rows up / down
X	Open item full screen
SELECT	Open the sync overview
START	Exit

Full-screen view:

Button	Action
Left / Right	Previous / next item
X	Play video / retry a failed photo
O	Back to grid
SELECT	Open the sync overview
START	Exit

Sync overview (SELECT):

Button	Action
X	Queue all local-only files to upload
O / SELECT	Back
START	Exit

Video playback:

Button	Action
X	Pause / resume
Left / Right	Seek ±10 seconds
O	Stop and go back

More of the library is fetched automatically (100 photos at a time, newest first) as you scroll toward the end. Errors are shown on screen and logged to ux0:data/vitaimmich/log.txt.

Syncing the Vita's camera media

On startup the app mounts the Photos app's storage (photo0:, i.e. the ACL-protected ux0:picture where camera shots and recordings live) via sceAppMgrAppDataMount, scans it (plus ux0:video/CAMERA, a few levels deep; .jpg/.jpeg/.png/.mp4) and merges those files into the same date-sorted grid as your server library. Files larger than 512 MB are skipped so a movie collection in ux0:video is never hashed or offered for upload. Both knobs live in config.txt: syncdir=<folder> (repeatable, replaces the default scan locations) and syncmaxmb=<MB> (the size cap; 0 disables it). A small badge in the top-left corner of each cell shows its status:

blue-grey dot — cloud only (a server asset not present on the Vita)
orange up-arrow — local only (on the Vita, not yet on the server)
blinking orange — queued / uploading
green check — backed up (exists on both; shown once, as the server asset)
red dot — failed (see the sync overview for the reason)

A background thread hashes each local file (SHA1) and asks the server which ones already exist (POST /api/assets/bulk-upload-check). Hashing and the duplicate check start automatically. Uploads do not start on their own: open the sync overview with SELECT and press X to queue every local-only file. Each upload is a POST /api/assets multipart request with an x-immich-checksum header for fast server-side dedup; progress is shown in the overview.

PoC limitations

TLS certificate verification is disabled (no CA bundle is shipped), so prefer plain HTTP on a trusted LAN or treat HTTPS as unverified.
Thumbnails stream in on a background thread (one at a time over a keep-alive connection); cells show a grey placeholder until loaded.
Videos are downloaded in full to ux0:data/vitaimmich/video.mp4 before playback (deleted afterwards), so they need free space on the memory card and a moment to start. Playback uses the Vita's hardware decoder via SceAvPlayer, so only MP4 (H.264/AAC) plays — Immich's transcoded video/playback stream is used, which is H.264 with default server settings.
Caps at 1000 server assets and 500 local camera files per launch; no albums or search.
Local media sync is one-way (Vita → server). It scans ux0:picture and ux0:video/CAMERA by default (the standard camera locations), recursing ~2 levels; use syncdir= in the config to scan other folders.
Local videos have no poster-frame thumbnail (the Vita has no still decoder for arbitrary MP4 frames), so their grid cell is a dark placeholder with the VIDEO badge; opening one still plays it.
Hashing 500 files at startup takes a while; it runs in the background so browsing is never blocked, but statuses fill in gradually.
deviceId is hard-coded to "PS Vita" and uploads are not associated with an album.
