WebRTC Android H264 硬解码支持更多的机型

webrtc更新日期 2017.11.01

WebRTC默认支持使用了高通,英特尔和三星CPU等国际大厂的机型,很多小众的机型或者新生的CPU没有开启支持,需要我们手动添加

修改方法:WebRTC通过MediaCodec来支持硬编码,我们需要修改的核心文件为以下两个

./src/webrtc/sdk/android/api/org/webrtc/MediaCodecVideoEncoder.java
./src/webrtc/sdk/android/api/org/webrtc/MediaCodecVideoDecoder.java

改动后的代码

private static final String[] supportedH264HwCodecPrefixes = {
    "OMX.qcom.", "OMX.Intel.", "OMX.Exynos."
    ,"OMX.Nvidia.H264."     /*Nexus 7(2012), Nexus 9, Tegra 3, Tegra K1*/
    ,"OMX.ittiam.video."    /*Xiaomi Mi 1s*/
    ,"OMX.SEC.avc."         /*Exynos 3110, Nexus S*/
    ,"OMX.IMG.MSVDX."       /*Huawei Honor 6, Kirin 920*/
    ,"OMX.k3.video."        /*Huawei Honor 3C, Kirin 910*/
    ,"OMX.hisi."            /*Huawei Premium Phones, Kirin 950*/
    ,"OMX.TI.DUCATI1."      /*Galaxy Nexus, Ti OMAP4460*/
    ,"OMX.MTK.VIDEO."       /*no sense*/
    ,"OMX.LG.decoder."      /*no sense*/
    //,"OMX.rk.video_decoder."/*Youku TVBox. our service doesn't need this */
    //,"OMX.amlogic.avc"      /*MiBox1, 1s, 2. our service doesn't need this */
};
