如何使用WebRTC的Android API设置硬件编码器

Question

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

看看Kotlin:中的这个精彩例子

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)
}

以及对应的Java类：

/** 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;
}
