让我们从HardwareVideoEncoderFactory开始。 这里我们看到了一个很直白的名为HardwareSupportedInCurrentSdkH264的方法: private boolean isHardwareSupportedInCurrentSdkH264(MediaCodecInfo info) { // First, H264 hardware might perform poorly on this model. if (H264_HW_EXCEPTION_MODELS.contains(Build.MODEL))...
实现编码器 然后是基于FFmpeg对VideoEncoder接口的实现,对FFmpeg的使用我主要参考了官方Example。然后简单看看我们需要实现VideoEncoder的什么接口吧: FFmpegH264EncoderImpl(constcricket::VideoCodec&codec,boolhardware_accelerate);~FFmpegH264EncoderImpl()override;// |max_payload_size| is ignored.// The following ...
A major feature of WebRTC is the ability to send and receive interactive HD videos. Fast processing of such videos requires hardware accelerated video encoding. The open-source WebRTC project framework currently supports several software encoder types: VP8, VP9, and H264.NVIDIA®has integrated ...
其他类只是包装类,比如native层VideoEncoderWrapper可以用于包装java层HardwareVideoEncoder,因为编码操作都是从native层调用的,借助VideoEncoderWrapper就可以在native层统一接口了。同理native层的VideoEncoderFactoryWrapper可以用于包装java层VideoEncoderFactory对象。

WebRTC enables streaming video between peers. It can stream video rendered by Unity to multiple browsers at the same time. Codec Encode There are two types of encoder for video streaming, one is using hardware for encoding and one is using software. Regarding different kinds of codecs, the ...
