我正在尝试使用Linphone在我的swift应用程序上启用视频通话 . 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)     
}

    这段代码组合修复了我的问题

    private func bridge<T: AnyObject>(obj : T) -> UnsafeRawPointer {
    let pointer = Unmanaged.passUnretained(obj).toOpaque()
    return UnsafeRawPointer(pointer)
}

let viewPointer = UnsafeMutableRawPointer(mutating: bridge(obj: view))
linphone_core_set_native_video_window_id(theLinphone.lc, viewPointer)
let previewPointer = UnsafeMutableRawPointer(mutating: bridge(obj: previewStream))
linphone_core_set_native_preview_window_id(theLinphone.lc, previewPointer)
