HUAWEI Mate20 webrtc崩溃issue:Failed设置远程应答sdp: Failed to set remote video description send parameters
HUAWEI Mate20 webrtc crash issue:Failed to set remote answer sdp: Failed to set remote video description send parameters
我正在为我们的 Android 混合应用程序添加原生 AWS webrtc。它在其他智能手机上运行良好，但在华为上会崩溃。当 webrtc 连接成功时，App 崩溃了。这是日志的一部分：

主要错误信息为：

让我感到困惑的是，在 sdp 中，编解码器是这样的：
a=rtpmap:98 VP9/90000
但在 sdp 答案中我发现：
a=rtpmap:0 H264/90000
这是导致崩溃的主要原因吗？在其他智能手机上（我试过小米，三星，vivo），这两条sdp线都是H264。但是华为确实支持H264，这是我的HUAWEI Mate 20 codecInfo:

我也尝试阅读 webrtc 代码，我在 MediaCodecVideoDecoderFactory 中找到了这个：
private boolean isH264HighProfileSupported(MediaCodecInfo info) {
String name = info.getName();
if (VERSION.SDK_INT >= 21 && name.startsWith("OMX.qcom.")) {
return true;
} else {
return VERSION.SDK_INT >= 23 && name.startsWith("OMX.Exynos.");
}
}
我怀疑 webrtc 不支持像 OMX.google.xxxxx 这样的编解码器。但是我不能修改这段代码，请问如何修改才能验证。
顺便说一下，这是我在 gradle 中的 webrtc 实现，如果有帮助：
implementation 'org.webrtc:google-webrtc:1.0.28513'
AWS webrtc代码来自AWS webrtc demo App，你可以在这里获取：awswebrtcdemoapp
很抱歉我不能提供我的源代码。
WebRTC Android只支持qcom和Exynos硬件H264编码器，可以修改HardwareVideoEncoderFactory中的isHardwareSupportedInCurrentSdkH264来支持其他平台如OMX.hisi,OMX.MTK.
然后构建 WebRTC 以在您的项目中使用 libwebrtc.jar 和 libjingle_peerconnection_so.so 而不是
implementation 'org.webrtc:google-webrtc:1.0.28513'
如何下载和构建 WebRTC Android：
https://webrtc.github.io/webrtc-org/native-code/android/
我正在为我们的 Android 混合应用程序添加原生 AWS webrtc。它在其他智能手机上运行良好，但在华为上会崩溃。当 webrtc 连接成功时，App 崩溃了。这是日志的一部分：

主要错误信息为：
E/KinesisVideoSdpObserver: onSetFailure(): Error=Failed to set remote answer sdp: Failed to set remote video description send parameters.
让我感到困惑的是，在 sdp 中，编解码器是这样的：
a=rtpmap:98 VP9/90000
但在 sdp 答案中我发现：
a=rtpmap:0 H264/90000
这是导致崩溃的主要原因吗？在其他智能手机上（我试过小米，三星，vivo），这两条sdp线都是H264。但是华为确实支持H264，这是我的HUAWEI Mate 20 codecInfo:

我也尝试阅读 webrtc 代码，我在 MediaCodecVideoDecoderFactory 中找到了这个：
private boolean isH264HighProfileSupported(MediaCodecInfo info) {
String name = info.getName();
if (VERSION.SDK_INT >= 21 && name.startsWith("OMX.qcom.")) {
return true;
} else {
return VERSION.SDK_INT >= 23 && name.startsWith("OMX.Exynos.");
}
}
我怀疑 webrtc 不支持像 OMX.google.xxxxx 这样的编解码器。但是我不能修改这段代码，请问如何修改才能验证。
顺便说一下，这是我在 gradle 中的 webrtc 实现，如果有帮助：
implementation 'org.webrtc:google-webrtc:1.0.28513'
AWS webrtc代码来自AWS webrtc demo App，你可以在这里获取：awswebrtcdemoapp
很抱歉我不能提供我的源代码。
WebRTC Android只支持qcom和Exynos硬件H264编码器，可以修改HardwareVideoEncoderFactory中的isHardwareSupportedInCurrentSdkH264来支持其他平台如OMX.hisi,OMX.MTK.
然后构建 WebRTC 以在您的项目中使用 libwebrtc.jar 和 libjingle_peerconnection_so.so 而不是
implementation 'org.webrtc:google-webrtc:1.0.28513'
