X264Android

Description

x264 jni for android

Using

• Make sure you have the jcenter repository included in the build.gradle file in the root of your project:

repositories {
    jcenter()
}

• Include the following in your module's build.gradle file:

compile 'com.github.bakaoh:x264-android:X.X.X'

for the version X.X.X, see the project on Bintray.

• Create X264Encoder and X264Params

X264Encoder encoder = new X264Encoder();

X264Params params = new X264Params();
params.width =  1280;
params.height = 720;
params.bitrate = 1000 * 1024;
params.fps = 25;
params.gop = params.fps * 2;
params.preset = "ultrafast";
params.profile = "baseline";

• Init encoder

X264InitResult initRs = encoder.initEncoder(params);

if (initRs.err == 0) {
  // process initRs.sps, initRs.pps
}

• Encode frame

X264EncodeResult encodedFrame = encoder.encodeFrame(inputFrame, X264Params.CSP_NV21, presentationTimestamp);

if (encodedFrame.err == 0) {
  // process encodedFrame.data
}

Build instructions

• Set the following environment variable:

X264_ANDROID_ROOT="<path to x264android checkout>"

• Download the Android NDK and set its location in an environment variable:

NDK_PATH="<path to Android NDK>"

• Fetch and build libx264.

cd "${X264_ANDROID_ROOT}/x264/src/main/cpp" && \
git clone http://git.videolan.org/git/x264.git libx264 && \
./build_x264.sh

• Open project in Android Studio to build the JNI native libraries.
