相当给力的项目，最近我也在研究这块东西，请问您觉得instagram用的是什么方案？
我反编译了他们的APK，发现他们android声明文件里面有opengl的声明，那应该是用opengl，但他们并没有限制4.3以上设备能使用。因此估计不能使用 grafika方案。然后看了下它们的.so文件，发现都很小，不知道是不是自己写的编码器，引用ffmpeg似乎会很大。感觉它们这块做得相当好。
图片平移问题
作者您好，最最近我在使用opengles2.0 做一个图片平移的效果，在广告板子上面抖动的厉害，您能指教一下么
为什么ToneCurve使用的是GLES20.GL_TEXTURE_2D？
为什么ToneCurve使用的是GLES20.GL_TEXTURE_2D，而不是GLES11Ext.GL_TEXTURE_EXTERNAL_OES，你的说明里面说的是用的GLES11Ext.GL_TEXTURE_EXTERNAL_OES
录制的视频有时无法播放
在录制的时候，录完，立刻播放时，有时会出现无法播放。不知道怎么回事。
Crash while recording
Device:Samsung s7 edge
Android:6.0.1
Fatal signal 11 (SIGSEGV), code 1, fault addr 0x0 in tid 4167 (TextureMovieEnc)
录制的时候，生成的mp4文件没有声音
录制的时候，生成的mp4文件没有声音，不知道是什么原因
请问怎样录制声音？
FilterGroup 有个bug,滤镜多于2个时会报错
GLES20.glGenFramebuffers(1, mFrameBuffers, 0);
改为
GLES20.glGenFramebuffers(1, mFrameBuffers, i);
会正常
关于滤镜组
试了一下filtergroup 高斯模糊，无法运行。研究了以后发现第二个滤镜必须使用image类型的，因为纹理类型不同。但是摄像头预览画面变的旋转，不完整了。一直没有找到问题原因。希望能协助解决，谢谢！
