how to switch to front camera?

Hi you, thanks for you share. I love this very much.
happying when enjoy it, but I cant open front camera, can you show me?
Thanks

把工程导入到Eclipse，运行点击imageView是崩溃

Image Editor For Android Studio

This project is still under coding and will be updated later,only used eclipse because my computer too poor to run AS T-T

My Question :
ImageEditor doesn't work in android studio right now ?

Camera rotation issue in Android Studio Project

Fix these 2 bugs:-
1: When I open camera rear camera opens -> switch to front camera -> go back -> again open camera
now camera preview is rotated from left to right.
2: In Nexus 5 rear camera is rotated to down side.

app crash on Galaxy s3

just try running this app on s3 and it crash but work fine on s4 with 5.0.1. i was figuring out the problem but not successful with that i think so GLES20 make it crash. anyway please try to figure out the problem please thanks!

美颜滤镜背景如何不变得亮白

最低水平的美颜效果都会导致背景也明显亮白，如果是正常和美颜切换时，背景不要那么明显的变化呢，人脸变化就可以了

bug:

Hi,
Error:Error: This fragment should provide a default constructor (a public constructor with no arguments) (com.seu.magiccamera.view.edit.adjust.ImageEditAdjustView) [ValidFragment]?

两个滤镜黑屏出错

在用 美肤 和 美白 这两个滤镜的时候，一只黑屏，下面着两行log重复打印

求解决。

关于MagicBeautyFilter中一行代码的问题^_^

我在准备一直iOS的过程中查看MagicBeautyFilter的代码发现在setBeautyLevel 函数中有一句
case 2:
setFloatVec3(mParamsLocation, new float[] {0.8f, 0.9f, 0.2f, 0.2f});
但是在后面的float 数组中给的是四个值。这里是否有错误？因为Vec3 应该只接受三个值吧

ImageView

eclipse版本 ImageView 模块无法启动

前置摄像头相关问题

你好，这个AndroidStudio 版demo中默认打开的是后置摄像头。
如果改为打开前置摄像头（CameraEngine中的cameraID=1;），默认对着人脸，则保存的录像文件图像是倒着的？ 这个怎么解决？

shader 有个地方看不懂，望指教！

MagicCamera\Project_eclipse_old\MagicFilter\res\raw\beautify_fragment_low.glsl

vec2 * vec2 结果是？
一般看到的高斯滤镜 是水平，垂直2次滤镜操作的。
你这个一次完成。
singleStepOffset = vec2(0.1, 0.1);
singleStepOffset * vec2(5.0, -8.0) = vec2(0.5, -0.8) 还是其他？

我感觉预期应该是 vec2(0.5, -0.8)吧，但是感觉这个 * 既不是 点乘 又不是 叉乘。看不太懂。

...
uniform vec2 singleStepOffset;
...
void main(){
vec2 blurCoordinates[12];

blurCoordinates[0] = textureCoordinate.xy + singleStepOffset * vec2(5.0, -8.0);

...

请问磨皮效果怎样设置？

在项目演示图片中看到有调节磨皮和美白的效果，但是在下载的demo中没有此操作，代码中也没发现此效果的API，请问我应该在什么地方设置和调节磨皮效果吗？

摘出美颜部分

您好，如果我想摘出美颜功能中gl滤镜部分，是不是从MagicBeautyFilter.java和beautify_fragment.glsl两个文件中找就可以了呢

Error when I run the project and click on "ImageView"

I get this error when I run the project and click on "ImageView"

OPENGL与图像数据如何绑定？

你好，我看了一下你的源码，只是知道了滤镜功能是通过openGL实现的，openGL是如何与数据源绑定的？能修改YUV数据吗？

MagicCamera做手机直播

作者你好！我将你的MagicCamera用在手机直播推流端并开源了Yasea项目，您可以用Android Studio跑一个demo试试。当初主要看中了美颜磨皮部分，我尝试用摄像头实时磨皮。将magicfilter目录剥离出来，将MagicBeautyFilter作为滤镜放到CameraInputFilter里，shader使用beauty.glsl文件，实测效果还不错，摄像头预览并不卡。

但原beauty.glsl里对整个图像进行磨皮处理，使得帧率下降比较多，有一种优化方式是只对皮肤进行处理，样板如下：

varying highp vec2 textureCoordinate;
varying highp vec2 textureCoordinate2;
varying highp vec2 textureCoordinate3;
uniform sampler2D inputImageTexture;
uniform sampler2D inputImageTexture2;
uniform sampler2D inputImageTexture3;
uniform mediump float smoothDegree;

void main() {
    highp vec4 bilateral = texture2D(inputImageTexture, textureCoordinate);
    highp vec4 canny = texture2D(inputImageTexture2, textureCoordinate2);
    highp vec4 origin = texture2D(inputImageTexture3,textureCoordinate3);
    highp vec4 smooth;
    lowp float r = origin.r;
    lowp float g = origin.g;
    lowp float b = origin.b;
    if (canny.r < 0.2 && r > 0.3725 && g > 0.1568 && b > 0.0784 && r > b && (max(max(r, g), b) - min(min(r, g), b)) > 0.0588 && abs(r-g) > 0.0588) {
        smooth = (1.0 - smoothDegree) * (origin - bilateral) + bilateral;
    } else {
        smooth = origin;
    }
    smooth.r = log(1.0 + 0.2 * smooth.r)/log(1.2);
    smooth.g = log(1.0 + 0.2 * smooth.g)/log(1.2);
    smooth.b = log(1.0 + 0.2 * smooth.b)/log(1.2);
    gl_FragColor = smooth;
}

可惜我对glsl编程不了解，无法将改进的shader移植到MagicCamera，能否帮忙对beauty.glsl改进一下呢？谢谢！

onPreviewFrame data + OpenCV 实时处理的问题

你好，我也在相同的东西，除了实时滤镜之外，我还需要用OpenCV 做一些 识别算法，然后再实时GL 渲染。
所以不能用 Shader 直接进行 YUV2RGB的操作。 // 这里我不知道行不行，刚刚接触GL？

目前采用的是 JNI中进行 YUV2RGB 操作，然后进行 内容识别，GLSurfaceView中进行渲染，根据返回的识别的物体 坐标点 实时 进行贴图。 // 这样是否有效率问题？

在进行实时贴图时，与实际坐标有很大偏差，不知道你是否有类似的经验。

Thanks.

Image视图下,如果应用了MagicImageAdjustFilter,在调用MagicDisplay的getBitmapFromGL()后,得到的图片异常

异常表现:
1.小米机型得到的图片--显示字体"完成"镜像
2.其他手机输出的图片为:像素大小为原图大小, 但是有图的区域为GLSurfaceView显示的区域,其余区域为黑色.

请教一下大神,
1.为什么保存图片不直接获取当前GLSurfaceView显示的图片,而是对原图重新绘制?
2.我没有找到获取GLSurfaceView当前显示图片的方法,我用getDrawingCache()方法获取到的是黑色,没有图片,该如何获取呢?

谢谢大神了!

beautify_fragment.glsl文件放到推流库使用时黑屏

你好，无意间发现MagicCamera库，运行了一下，感觉效果非常好。
正好项目中需要用到滤镜，发现美颜滤镜比七牛推流库Android版中的美颜效果要好，尤其是磨皮效果明显，肤质显得更加细腻。
我将beautify_fragment.glsl放入七牛推流库，copy CameraFilterBeauty修改了一个类，无其他修改。

只是修改了这里（将fragment_shader_beauty 替换为 beautify_fragment ；R.raw.vertex_shader 改为 -1。
在GlUtil.createProgram（）函数中判断值为 -1 时将对应变量替换为你库中NO_FILTER_VERTEX_SHADER 对应的字符串）

@OverRide protected int createProgram(Context applicationContext) {
return GlUtil.createProgram(applicationContext, -1, R.raw.beautify_fragment);
}

我先将vec4 params直接在.glsl文件中赋值vec4 params = vec4(0.33, 0.63, 0.4, 0.35); 后来经过比对发现，七牛的fragment_shader_beauty.glsl文件除了uniform samplerExternalOES uTexture 与 sampler2D inputImageTexture类型不一致以外，其他都是一样。

但是本人glsl小白一枚，完全不知道该怎么修改。如果有空的话，还请大牛帮忙指导一下，万分感谢！

将shader脚本移到ios里面黑屏

我将cool.glsl里面的算法copy到iOS里面，预览黑屏。能麻烦看看是什么问题吗？我已有的灰度算法是正常的。

滤镜、编辑功能对图片修改后 返回键进行应用时会导致内存溢出

滤镜、编辑功能对图片修改后 返回键进行应用时会导致内存溢出，
错误信息为：
java.lang.OutOfMemoryError: Failed to allocate a 25958412 byte allocation with 4194304 free bytes and 11MB until OOM
at com.seu.magicfilter.display.MagicDisplay$2.run(MagicDisplay.java:175)
找到对应的行 为：MagicDisplay.java
Bitmap mBitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
该怎么解决这个问题呀，求解，正在运用你学的项目到我的项目中

编辑功能无法正常使用

在修改图片的透明度，或是饱和度等，返回时提示是否保存，点击保存，然后得不到修改后的图片，反而是得到一张无用的图片。希望大神指点迷津。感谢万分
