How do I install Jonis View?
On Windows, run the Microsoft Store installer. On Mac, choose Apple Silicon or Intel and open the DMG; macOS Ventura or later is required. On Linux, download the x64 AppImage and allow it to run. Some distributions require FUSE.
Which capture device can I use?
A UVC-compatible USB capture device recognised by your system. Resolution, frame rate and latency depend on the hardware and format. Close other apps using the device.
Can I record or stream?
Windows v0.3.0 saves PNG images, records MP4 clips and saves recent footage. Press P for an image and R to start or stop a clip. For live streaming, capture the app window with streaming software. Recording features are not available in macOS and Linux v0.1.2.
How do I save recent footage?
On Windows, enable 15, 30 or 60 seconds in Settings, then press B to save the available footage. Replay is off by default; changing the source, format or audio disables it. Saving starts a new history.
Where are files saved, and which audio is recorded?
On Windows, files go to Videos/Jonis View. Change or open the folder in Settings. The selected audio input is recorded; volume and mute only affect listening.
What does GPU export do?
On Windows, it accelerates MP4 export when your GPU and drivers support it. Enable it in Settings; it is off by default. If it fails, the app retries with the CPU. PNG captures are unaffected.
How do I change the language?
Windows v0.3.0 uses the first preferred Windows language: Spanish, English, French, German, Swedish or Russian. Unsupported languages fall back to English. Restart the app after changing the Windows language.
