HUAWEI Mate20 webrtc crash issue:Failed to set remote answer sdp: Failed to set remote video description send parameters

I'm working on adding native AWS webrtc for our Android hybrid App. It works well on other smartphones but will crash on HUAWEI. When the webrtc connection succeed, App crashed. Here is the part of the Log:

A/libc: Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x753b600000 in tid 23629 (AudioTrackJavaT), pid 22933 (m.sercomm.s1app)
E/RtgSchedManager: endActivityTransaction: margin state not match
Disconnected from the target VM, address: 'localhost:53093', transport: 'socket'

The main error Info is:

E/KinesisVideoSdpObserver: onSetFailure(): Error=Failed to set remote answer sdp: Failed to set remote video description send parameters.

What I'm confused is that in sdp offer, the codec be like:

a=rtpmap:98 VP9/90000

But in sdp answer I found:

a=rtpmap:0 H264/90000

Is this the main cause of the crash? On other smartphone(I tried Xiaomi, Samsung, Vivo),this two sdp lines are both H264. But HUAWEI do support H264, this is my HUAWEI Mate 20 codecInfo:

And I also try to read webrtc code, I found this in MediaCodecVideoDecoderFactory:

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.");
}

}

I doubt webrtc did not support codec like OMX.google.xxxxx . But I can't modify this code, how can I modify it so I can have a verification.

By the way, this is my webrtc implementation in gradle, if it helps:

implementation 'org.webrtc:google-webrtc:1.0.28513'

The AWS webrtc code is from AWS webrtc demo App, you can get here:awswebrtcdemoapp

And I'm sorry I can not offer my source code.

WebRTC Android only support qcom and Exynos hardware H264 encoders, you can change isHardwareSupportedInCurrentSdkH264 in HardwareVideoEncoderFactory to support other platforms such as OMX.hisi, OMX.MTK.

And then build the WebRTC to use libwebrtc.jar and libjingle_peerconnection_so.so in your project instead of

implementation 'org.webrtc:google-webrtc:1.0.28513'
