Environment

* Unity version:2022.3

Steps To Reproduce

1. import package WebRTC 3.0.0-pre.7
2. in unity Create Scene
3. Create video-related objects, such as Camera, RawImage...

Current Behavior

When the video track is running on Android, the video source cannot be sent
I don't know what the problem is. It can run when editing, but after packaging into an App, the video cannot be sent to the service. The program code is as follows:

 peerConnection = new()
        {
            OnIceConnectionChange = state => { Debug.Log("IceConnectionState: " + state); },
            OnConnectionStateChange = state => { Debug.Log("ConnectionState: " + state); },
            OnIceGatheringStateChange = state => { Debug.Log("IceGatheringState: " + state); },
            // OnIceGatheringChange = state => { Debug.Log("IceGatheringState: " + state); },
            OnIceCandidate = state => { Debug.Log("OnIceCandidate: " + state); },
            OnDataChannel = state => { Debug.Log("OnDataChannel: " + state); },
            OnNegotiationNeeded = () => { Debug.Log("OnNegotiationNeeded: "); },
            OnTrack = state => { Debug.Log("OnTrack: " + state); },
            // OnRemoveTrack = state => { Debug.Log("OnRemoveTrack: " + state); },
        };
        videoTrack = _camera.CaptureStreamTrack(localView.texture.width, localView.texture.height);
        peerConnection.AddTrack(videoTrack);

        StartCoroutine(WebRTC.Update());

        var offer = peerConnection.CreateOffer();
        yield return offer;

        var offerDesc = offer.Desc;

        var opLocal = peerConnection.SetLocalDescription(ref offerDesc);
        yield return opLocal;

        var filteredSdp = "";

        foreach (string sdpLine in offer.Desc.sdp.Split("\r\n"))
        {
            if (!sdpLine.StartsWith("a=extmap"))
            {
                filteredSdp += sdpLine + "\r\n";
            }
        }

        Debug.LogWarning(filteredSdp);

        using (UnityWebRequest www = new(
                $"https://webrtcpush.tlivewebrtcpush.com/webrtc/v2/whip",
                UnityWebRequest.kHttpVerbPOST
            ))
        {
            www.uploadHandler = new UploadHandlerRaw(Encoding.ASCII.GetBytes(filteredSdp));
            www.downloadHandler = new DownloadHandlerBuffer();
            www.SetRequestHeader("Content-Type", "application/sdp");
            www.SetRequestHeader("Authorization", $"Bearer {webrtcUrl}");

            yield return www.SendWebRequest();

            if (www.result != UnityWebRequest.Result.Success)
            {
                Debug.LogWarning(www.error);
            }
            else
            {
                Debug.LogWarning(www.downloadHandler.text);

                var answer = new RTCSessionDescription { type = RTCSdpType.Answer, sdp = www.downloadHandler.text };
                var opRemote = peerConnection.SetRemoteDescription(ref answer);
                yield return opRemote;
                if (opRemote.IsError)
                {
                    Debug.LogWarning(opRemote.Error);
                }
                else
                {
                    // Debug.LogWarning(opRemote.Current);
                }
            }
        };

Expected Behavior

When starting stream video call,you can pull video

Anything else?

return version to package WebRTC 3.0.0-pre.6 can Publish Streaming
