What you can play.

Local files: Open files from your computer.
Video URLs: Paste a URL. Requires yt-dlp to be installed separately. What plays and what does not.
Capture devices: Webcams, OBS Virtual Camera, and USB HDMI capture cards.
Desktop capture: Stream a monitor to the goggles with your computer's sound, or keep the sound on local headphones behind a delay so it matches the picture. Cursor optional, quality and frame rate adjustable. The picture runs a few seconds behind.
File formats: Containers: MP4, MKV, MOV, AVI, WMV, FLV, WebM, M4V, TS, M2TS. Video codecs: H.264, HEVC, AV1, VC-1, MPEG-2, and more. Audio codecs: AAC, AC3, DTS, Opus, MP3, FLAC, and more.

How it reaches the device.

DLNA discovery: Finds renderers on your local network.
Codec handling: H.264 + AAC in MP4 plays as-is. The same codecs in MKV or AVI are repackaged to MP4 with no re-encode, so they keep full quality and seek like MP4. Everything else converts to H.264 automatically.
Hardware encoding: Intel Quick Sync, NVIDIA NVENC, or AMD AMF. OpenH264 fallback when none is available.
Max resolution: Default 1080p (Goggles native). Configurable.
Seeking: Files that play directly, repackaged, or converted scrub instantly. A live transcoded stream seeks by restarting at the new position.

Routing and sync.

Split audio: Video to the renderer, audio to a local speaker or Bluetooth headphone. How to set it up.
Automatic sync: On the Local output, the audio on your PC locks to the video on the goggles on its own and holds, so it doesn't drift over a long movie. How it works.
Convert for sync: A format that has to be fully converted, such as HEVC, plays live right away and converts to a regular file in the background, so automatic sync and instant seeking switch on. Keep live stays on the live stream if you prefer.
Manual fine adjustment: The A/V OFFSET control nudges audio in 10/50/500 ms steps to calibrate your headset's fixed delay once. A green Auto-sync indicator shows while the app is holding sync on its own.
Multi-track selection: Pick the audio track on multi-track files.
Drift detection: If a network hiccup causes drift, an amber banner offers one-click resync.

Sidecar and embedded.

Supported formats: SRT, ASS, SSA sidecars and embedded text tracks from MKV.
Language detection: Filename suffixes like .en.srt or .eng.srt are mapped to language tags.
Burn-in: Subtitles are burned into the video.
Time offset: Per-file offset for out-of-sync SRTs.

Playback options.

Light and dark themes: Follows Windows. Manual override in Settings.
Cinema mode: Darkens the screen. Can also turn off the display when the Stream output is selected. Optional in Settings.
Resume positions: Files resume where you left off.
Queue persistence: The queue survives restarts.
Auto-advance: Optional. Plays the next item when the current one finishes.
Keyboard shortcuts: Press F1 in the app for the full list.

What the app does not do.

No account: Nothing to sign up for. No email required.
No cloud: Video files never leave your local network.
No telemetry: No analytics, usage tracking, or automatic uploading of crash reports.
No advertising: No banners, upsells, or referral links.
