CosmoViewerNG for Windows and Insta360 cams

Insta360 EVO and Insta360 X2 tested. Other models should also work, but they need to be tested and confirmed.

Insta360 EVO can be connected only with Wi-Fi. Insta360 X2 can be connected with Wi-Fi or with USB cable.

Connection to camera

Wi-Fi connection

Just connect your PC Wi-Fi to Insta360 camera Wi-Fi network. Default password for EVO is 12345678, default password for X2 is 88888888.
Note: be carefull! The password on these Insta360 cameras cannot be changed even in the official app, so any of your neighbors can access your camera and, possible, to your PC if it connected to camera Wi-Fi. Discussion on Reddit

USB connection

1. Switch USB mode on Insta360 X2 to "Android" (Swipe from up to down on Insta360 X2 display, swipe from right to left, click gears icon, menu "General" -> "USB mode", choose "Android")
   
2. Connect your Insta360 X2 to PC with a standard USB-C cable.
   
3. In some cases also need to instal WinUSB driver, follow next steps

3. Go to chapter "Cameras". Choose "Insta360" in list and click "Save"
   
   
   
4. One or more devices should be found in list (the same camera but on diffent network interfaces)
   
   
   
5. Click any device (better to use device with address "127.0.0.1") and you should see video if camera already connected. Settings available as "gears" icon in left panel

Changing preview resolution

Click "Camera settings" icon, tab "Video output". Change resolution in list. Click on "Save" button is not needed

Real-time panorama stitching

NVidia graphics card ONLY (at current moment)

Most important feature - real-time stitching from two fisheyes into equirectangular format. It's strongly needed if you want to stream on Youtube. Unfortunately, Insta360 EVO and X2 does not support onboard stitching. Native Insta360 application can do stitching, but resolution is limited on 1280s. CosmoViewerNG can do stitching in 4K resolution (3840x1920) up to 60 FPS, but powerfull graphics card is needed for encoding stitched video in H264 codec. For example, my GTX 1650 SUPER is well fast for do 4K stitching on 30 FPS with a small latency, but in 60 FPS latency is big.

1. Click "Camera settings" icon, tab "Stitching"
   
   
   
2. Check option "Enable two-fisheyes to equirectangular stitching"
   
3. Other params is by default for Insta360 X2 camera, don't change it if you are not sure what you do
   
4. "Resize output video" is usefull for Youtube streaming, to correct video resolution
   
5. "HW acceleration" strongly recommended. At current moment only NVidia graphics cards are supported.
6. Click "Save" and you should see video in equirectangular format
   
   
   

Stitching details

I use Gstreamer glshader element to make stitching. GLSL shader from this repo https://github.com/izmhr/EquirectangularMapOnWebGL
Fragment shader file is placed in CosmoViewerNG installation directory, so you could change it if you want to do it better.
Stitching is not ideal yet, need to find better values. But it is already could be used.
