## FFMPEG
Scene Detection :
ffmpeg -f dshow -i video="OBS Virtual Camera" -filter:v "select='gt(scene,0.2)',showinfo" -f null -


## How to build ffmpeg with NDI IO
I was able to find a VERY QUICK AND DIRTY way to use the media-autobuild suite to compile my own 64-bit static FFmpeg for Windows with the NDI library.

Download it and extract to a place on your computer, and keep note of the path. I put it in "D:\ndi\media-autobuild_suite-master", so for the sake of these instructions when you see "<autobuild>", you need to substitute whatever path you've put it in.

During the initial setup process, request to use the static build and add whatever else you'd like to have in your ffmpeg, then pause what you're doing when the on-screen prompts tell you the ffmpeg_options file has been written, then go into <autobuild>\build\ffmpeg_options.txt and add somewhere a line with

Code:
--enable-libndi_newtek

## Socket IO reminder
// sending to sender-client only
socket.emit('message', "this is a test");

// sending to all clients, include sender
io.emit('message', "this is a test");

// sending to all clients except sender
socket.broadcast.emit('message', "this is a test");

// sending to all clients in 'game' room(channel) except sender

    How to get NDI output to work in CasparCG


Install NewTek Network Video Send.exe
Install NewTek NDI AirSend Updater.exe
The AirSend Updater has a bug, and will not properly copy the x64 version of the DLL to the correct place. So, you'll need to manually copy C:\Program Files\NewTek\NewTek NDI AirSend Updater\Processing.AirSend.x64.dll to C:\Windows\System32\, overwriting the existing file.
Restart your PC.
Configure the CasparCG Server to use a Newtek iVGA output. Even though it says iVGA, it will actually be outputting NDI thanks to the updated AirSend DLLs.


You can do this manually by adding a `` consumer to your casparcg.config, or you can do it via the third-party [Caspar


## Unity - GET Sprite from URL
 public void StartLoadingPhoto(){
        IEnumerator coroutine = LoadPhoto("http://website/photo.png");

    {
        string url = url;
        Texture2D tex;
        tex = new Texture2D(4, 4, TextureFormat.DXT1, false);

## Rotate Point around Point
 function rotatePoint(point, center, angle){
    angle = (angle ) * (Math.PI/180); // Convert to radians
    var rotatedX = Math.cos(angle) * (point.x - center.x) - Math.sin(angle) * (point.y-center.y) + center.x;
    var rotatedY = Math.sin(angle) * (point.x - center.x) + Math.cos(angle) * (point.y - center.y) + center.y;

    return new THREE.Vector2(rotatedX,rotatedY);
}
