AVG reports a trojan for v2.2

A check with VirusTotal reports a trojan named "Android/C2M.I.62A80EEE7B6C" for v2.2. Any idea what could cause it? To me it looks like a "false positive" (especially as only 1 out of 55 engines reports it), but there's no background info on it. Would be nice to get rid of that nasty flag :)

Camera access is required

I just run on android studio3.1.2, but when app run, show this error:"Camera access is required". And I look at the source .code, it is here, how can I resolve this bug?

 if (ContextCompat.checkSelfPermission(this,
            Manifest.permission.CAMERA)
            != PackageManager.PERMISSION_GRANTED && permit) {

        // Should we show an explanation?
        if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.CAMERA)) {
            Toast.makeText(this, "Camera access is required.", Toast.LENGTH_SHORT).show();

        } else {
            ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.CAMERA},
                    REQUEST_CAMERA_PERMISSION);
        }

    } else {
        setupCameraPreviewView();
    }

Android 6 - on the first run does not display anything in the TextView

But if restart the app - all works fine. I think the problem still in runtime permissions

I tried a lot but cannot figure out how.

Save video?

How can I save the preview as a video?

Camera not working for first time

In android 7.0, app first of all asks for permission to take pictures and record video . On allowing it, just the white screen comes with no camera as shown. Although, on restarting the app , camera is working absolutely fine.

Also, in the Filter named 'Cracked', the feature is working fine but with a little bit of lag

Please check

Texture2D compatibility issue

I was using ShaderToy to create a filter of my own and when I put it on the app, it seems to be a compatibility issue involving the texture class.

It appears that ShaderToy has the new version in which Texture2D was replaced by only texture and that's how I built my shader on the online tool:

void mainImage(out vec4 fragColor, in vec2 fragCoord) {
    vec2 uv = fragCoord.xy;
    int id = 5;
    vec3 s = texture(iChannel0, fragCoord.xy / iResolution.xy).xyz;

    vec3 c = vec3(50, 50, 50);
    vec4 K = vec4(0.0, -1.0 / 3.0, 2.0 / 3.0, -1.0);
    vec4 p = mix(vec4(c.bg, K.wz), vec4(c.gb, K.xy), step(c.b, c.g));
    vec4 q = mix(vec4(p.xyw, c.r), vec4(c.r, p.yzx), step(p.x, c.r));
    float d = q.x - min(q.w, q.y);
    float e = 1.0e-10;
    vec3 dest = vec3(abs(q.z + (q.w - q.y) / (6.0 * d + e)), d / (q.x + e), q.x);

    vec3 color = max(s,dest);
    fragColor = vec4(color,1.0);
}

If I put the code like this on the app, the screen turns black, that because of the texture that is not supported. If I simply change from texture to texture2D in line 4, is like the entire screen in only one huge pixel that changes color as I move my camera.

Do you have any idea how I can change this code or the one on MyGLUtils class so it will work properly?

how to appy the filters in bitmap

hi ,thanks so much for this greate work, i have a question there's any way to apply the filters in image seleted from gallery

frame > float[] > render float[]

Hi,
After lots of time trying to find a camera preview approach for fast video processing, this one seems the best.
Our goal is to

• capture each frame using this library
• get the rbg values into a float[]
• send it to a tensorflow graph & get it back
• render the new float[] using this library, like overriding the OriginalFilter

Could you please help us finding the fastest way to achieve the 2nd and 4th steps ?

Video Recording

Can i record video using these filters ? Please help me
