# x264 & libyuv for Android
Preview frame scale & encoder to h264 using native libraries
* [x264]
* [libyuv]
### Usage
```
override fun onPreviewFrame(data: ByteArray, camera: Camera) {
val rotated = yuvUtils.nV21Rotate(
data,
widthPreview,
heightPreview,
Key.ROTATE_90,
true
)
val rotatedNScaled = yuvUtils.nV21Scale(
rotated,
heightPreview,
widthPreview,
widthOut,
heightOut,
Key.SCALE_MODE_LINEAR,
)
h264Encoder.nV21ToH264(rotatedNScaled) { h264Frame ->
// process h264Frame
}
}
```
This example record a video h264 and save in
```
storage/emulated/0/Download/sample.h264
```
To reproduce this video you can use [VLC for Android]
### Build x264 lib for Android ABIs (armeabi-v7a, arm64-v8a, x86, x86_64)
* configure your local NDK, HOST_TAG and TOOLCHAIN in build_x264.sh script
```
export NDK=/home/dani/Android/Sdk/ndk-bundle
export HOST_TAG=linux-x86_64
export TOOLCHAIN=$NDK/toolchains/llvm/prebuilt/$HOST_TAG
```
* execute build_x264.sh - This script clone x264 repository and build different ABIs for android
```
# ./build_x264.sh
```
### Build libyuv lib for Android ABIs (armeabi-v7a, arm64-v8a, x86, x86_64)
* Coming soon..
