First of all, my English is very poor, I will use the software to translate a copy of English
我尝试给本地视频添加滤镜，
I tried adding filters to the local video
使用MediaCodec解码本地视频，得到视频每一帧的byte[]，
Use MediaCodec to decode the local video and get the byte[] of each frame of the video,
然后使用GPUImageView.updatePreviewFrame来刷新视图，
Then use the GPUImageView.updatePreviewFrame to refresh the view,
在使用默认的GPUImageFilter情况下，视频的颜色不正常。
When using the default GPUImageFilter, the video's color is not normal.
我查看了代码，发现GPUImageRenderer.onPreviewFrame默认使用了GPUImageNativeLibrary.YUVtoRBGA，
I looked at the code, I found GPUImageRenderer.onPreviewFrame Use GPUImageNativeLibrary. YUVtoRBGA by default
我尝试使用YUVtoARBG转换byte[]并展示到视图中，颜色是正常的
I tried to use YUVtoARBG to convert the byte[] and show it to the view, and the color is normal
