如何使用Android API for WebRTC设置硬件编码器

Question

我使用的是1.0.28513版本，不知道如何/在哪里指定VP8作为硬件加速的视频编解码器。

再见，

看看Kotlin中的这个wonderful example：

private val peerConnectionFactory: PeerConnectionFactory by lazy {
    //Initialize PeerConnectionFactory globals.
    val initializationOptions = PeerConnectionFactory.InitializationOptions.builder(this)
            .setEnableVideoHwAcceleration(true)
            .createInitializationOptions()
    PeerConnectionFactory.initialize(initializationOptions)

    //Create a new PeerConnectionFactory instance - using Hardware encoder and decoder.
    val options = PeerConnectionFactory.Options()
    val defaultVideoEncoderFactory = DefaultVideoEncoderFactory(
            rootEglBase.eglBaseContext, /* enableIntelVp8Encoder */true, /* enableH264HighProfile */true)
    val defaultVideoDecoderFactory = DefaultVideoDecoderFactory(rootEglBase.eglBaseContext)
    PeerConnectionFactory(options, defaultVideoEncoderFactory, defaultVideoDecoderFactory)
}

并发送到相应的Java class

/** Create encoder factory using default hardware encoder factory. */
public DefaultVideoEncoderFactory(
    EglBase.Context eglContext, boolean enableIntelVp8Encoder, boolean enableH264HighProfile) {
  this.hardwareVideoEncoderFactory =
        new HardwareVideoEncoderFactory(eglContext, enableIntelVp8Encoder, enableH264HighProfile);
}

/** Create encoder factory using explicit hardware encoder factory. */
DefaultVideoEncoderFactory(VideoEncoderFactory hardwareVideoEncoderFactory) {
    this.hardwareVideoEncoderFactory = hardwareVideoEncoderFactory;
}

应该能帮你弄清楚该在哪里行动

希望能有所帮助

祝你今天愉快,
