Question

我正在尝试使用Linphone在我的swift应用上启用视频通话。我能够启用音频通话，但我无法使用视频。如果我启用此行，应用程序将始终崩溃：

linphone_call_params_enable_video(linCallParams, 1)

我想在这里只接收视频和音频。

@objc func startVideoCall() {

    linphone_core_enable_video_display(theLinphone.lc, 1)
    linphone_core_enable_video_capture(theLinphone.lc, 1)

    let linCallParams = linphone_core_create_call_params(theLinphone.lc, nil)
    linphone_call_params_enable_video(linCallParams, 1)

    linphone_call_params_set_video_direction(linCallParams, LinphoneMediaDirectionSendRecv)
    linphone_call_params_set_audio_direction(linCallParams, LinphoneMediaDirectionSendRecv)

    let call = linphone_core_invite_with_params(theLinphone.lc, calleeAccount, linCallParams)

    linphone_core_set_native_video_window_id(theLinphone.lc, &videoStreamView)
    linphone_core_set_native_preview_window_id(theLinphone.lc, &videoStreamPreview)

    do {
        try audioSession.setActive(true)
    } catch {
        print("Audio error: \(error.localizedDescription)")
    }
    linphone_call_params_unref(linCallParams)     
}

此代码组合修复了我的问题

var data =  {ListofLayers: '[{"Key":"G1","Value":"park"}]'};
var JSONObject = JSON.parse(JSON.stringify(data));
var obj = JSON.parse(Object.values(JSONObject));

$.each(obj, function (key, value) {
    var s = '';
    $.each(value, function (key, value) {
        s += (s == '' ? value : (':' + value));       
    });
    console.log(s);
});

使用Linphone iOS SDK启用视频通话
