android – webrtc and peerjs and pixel 3 : How to resolve a video problem?

I’m using peerjs (1.3.2) on my ionic app with an android pixel 3 (version12 sp1a.210812)

When the communication is established the video received is distorded with green pixel at the bottom.
Apparently, the problem is known on the twilioplatform.
github.com/twilio/video-quickstart-android/issues/470

They say the problem will be with the VP8 codec and they recommend disabling it:
MediaCodecVideoEncoder.disableVp8HwCodec();

In my context i don’t have this function, so i followed this link to force h264 instead of vp8
webrtc and peerjs: how to choose H264 instead of vp8?

In my peerjs call function i have modified the sdp like this

peer.on('call', (call)=>{
    call.answer(stream,{sdpTransform:(sdp)=>{
        sdp = modifySDP(sdp);
        console.log(sdp);
        return sdp;
    }});
    call.on('stream', (remoteStream)=>{
        console.log("REMOTESTREAM");
        playStream(remoteStream);
    });           
});

My function sdp replace this line
m=video 60372 UDP/TLS/RTP/SAVPF 96 98 100 101 116 111

like this :
m=video 60372 UDP/TLS/RTP/SAVPF 100 96 98 101 116 111

But it doesn’t change anything.

So i have no more idea and your help will be grateful
