所以这是我的问题。我正在尝试使用索尼远程相机 API SDK 作为在 Visual Studio 中使用 C# 开发简单程序并控制 SDCQX-10 的指南。我尝试使用 kz-remote 应用程序......但无法解决。所以我决定通过使用网络套接字来完成它。一开始很精彩，但过了一段时间我决定试一试现场直播……然后一切都崩溃了。我的意思是，相机停止响应。我设法让镜头“关闭并再次打开（缩回）”，方法是取出电池并再次插入并打开相机，但是，当尝试拍照时，相机再次停止响应。好的，经过一些解决方法后，出现以下症状（相机已更新到 V3.0 固件）：
- 相机正常开机，通过手动控制可以放大和缩小 - 按下快门需要一段时间才能发出“拍照”声音（虽然没有拍照） -“拍照”后听到声音，红色 LED 指示灯（存取指示灯）保持亮起（ON） - 按下快门后，相机没有反应（放大/缩小禁用，快门也没有反应） - 关闭镜头时不收回
使用 PlayMemories Android 应用程序时（版本 5.7.0，西班牙语。Android V. 6.0.1 Asus Zenphone 2 Laser (ASUS_Z00TD) *以前可以正常使用 Playmemories）
- 相机连接“正常” - 没有实时取景可用（带有叠加控件的黑屏） - 从 android 设备放大/缩小作品 - 一段时间后显示“无法获得直接可视化图像”的东西 - 当远程按下快门 上述手动快门的所有症状也会发生。
最后，我尝试检查使用程序时发生了什么：我在按钮上使用以下代码连接相机（SDDP发现相机并检索信息）
private void button2_Click(object sender, EventArgs e)
{
IPEndPoint LocalEndPoint = new IPEndPoint(IPAddress.Any, 60000);
IPEndPoint MulticastEndPoint = new IPEndPoint(IPAddress.Parse("239.255.255.250"), 1900);
Socket UdpSocket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
UdpSocket.Bind(LocalEndPoint);
textBox1.AppendText("UDP-Socket setup done...\r\n");
string SearchString = "M-SEARCH * HTTP/1.1\r\nHOST:239.255.255.250:1900\r\nMAN:\"ssdp:discover\"\r\nST:urn:schemas-sony-com:service:ScalarWebAPI:1\r\nMX:3\r\n\r\n";
UdpSocket.SendTo(Encoding.UTF8.GetBytes(SearchString), SocketFlags.None, MulticastEndPoint);
textBox1.AppendText("M-Search sent...\r\n");
byte[] ReceiveBuffer = new byte[64000];
int ReceivedBytes = 0;
while (true)
{
if (UdpSocket.Available > 0)
{
ReceivedBytes = UdpSocket.Receive(ReceiveBuffer, SocketFlags.None);
if (ReceivedBytes > 0)
{
textBox1.AppendText(Encoding.UTF8.GetString(ReceiveBuffer, 0, ReceivedBytes));
}
break;
}
}
}
之后我得到这个回复：
HTTP/1.1 200 OK

我在另一个按钮上使用了这个脚本来测试不同的功能：
private void button3_Click(object sender, EventArgs e)
{
try
{
// Create a request using a URL that can receive a post.
WebRequest request = WebRequest.Create("http://10.0.0.1:10000/sony/camera ");
// Set the Method property of the request to POST.
request.Method = "POST";
// Create POST data and convert it to a byte array.
string postData = "{\"method\": \""+textBox2.Text+"\",\"params\": [],\"id\": 1,\"version\": \"1.0\"}";
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
// Set the ContentType property of the WebRequest.
request.ContentType = "application/x-www-form-urlencoded";
// Set the ContentLength property of the WebRequest.
request.ContentLength = byteArray.Length;
// Get the request stream.
Stream dataStream = request.GetRequestStream();
// Write the data to the request stream.
dataStream.Write(byteArray, 0, byteArray.Length);
// Close the Stream object.
dataStream.Close();
// Get the response.
WebResponse response = request.GetResponse();
// Display the status.
textBox1.AppendText(((HttpWebResponse)response).StatusDescription);
// Get the stream containing content returned by the server.
dataStream = response.GetResponseStream();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader(dataStream);
// Read the content.
string responseFromServer = reader.ReadToEnd();
// Display the content.
textBox1.AppendText(responseFromServer);
var fot = responseFromServer.Substring(20).Split('\"').FirstOrDefault();
//textBox2.AppendText(fot);
// Clean up the streams.
reader.Close();
dataStream.Close();
response.Close();
webBrowser1.Url = new Uri(fot);
// Follow intruction to try to visualize the image
//var client = new WebClient();
//client.DownloadFile(webBrowser1.Url, @"c:/foto.jpg");
//using (MemoryStream mem = new MemoryStream(dat))
//{
// using (var im = Image.FromStream(mem))
// {
// pictureBox1.Image = (Bitmap) im;
// }
//}
//pictureBox1.Image = Bitmap.FromFile(@"c:/foto.jpg");
}
catch (Exception ex)
{
}
}
拍照效果很好，我评论了最后几行，我用它们来检索图片（我把它们留在那里，因为在那之前它工作正常，用于拍照和可视化）
所以，我在崩溃之前没有数据（我感到羞耻）......但之后，这里有一些对 API 的响应：
采取行动
OK{"error":[40403,"Long shooting"],"id":1}
然后（当第二次按下并打开时）
OK{"error":[5,""],"id":1}
等待拍照
OK{"error":[40403,"Not Finished"],"id":1}（拍照后继续）
或者
OK{"error":[1,""],"id":1}（在没有拍照的情况下，上面和这个之间看起来有点随机）
获取事件
使用：\"params\": [false]
OK{"id":1,"result":[{"names":["getMethodTypes","getAvailableApiList","setShootMode","getShootMode","getSupportedShootMode","getAvailableShootMode","setSelfTimer","getSelfTimer","getSupportedSelfTimer","getAvailableSelfTimer","setPostviewImageSize","getPostviewImageSize","getSupportedPostviewImageSize","getAvailablePostviewImageSize","startLiveview","stopLiveview","actTakePicture","startMovieRec","stopMovieRec","awaitTakePicture","actZoom","setExposureMode","getExposureMode","getSupportedExposureMode","getAvailableExposureMode","setBeepMode","getBeepMode","getSupportedBeepMode","getAvailableBeepMode","setCameraFunction","getCameraFunction","getSupportedCameraFunction","getAvailableCameraFunction","setStillSize","getStillSize","getSupportedStillSize","getAvailableStillSize","actFormatStorage","getStorageInformation","setTouchAFPosition","cancelTouchAFPosition","getTouchAFPosition","getSupportedExposureCompensation","getSupportedWhiteBalance","getSupportedIsoSpeedRate","actHalfPressShutter","cancelHalfPressShutter","getApplicationInfo","getVersions","getEvent"],"type":"availableApiList"},{"cameraStatus":"IDLE","type":"cameraStatus"},{"type":"zoomInformation","zoomIndexCurrentBox":0,"zoomNumberBox":1,"zoomPosition":0,"zoomPositionCurrentBox":0},{"liveviewStatus":true,"type":"liveviewStatus"},{"liveviewOrientation":"0","type":"liveviewOrientation"},[{"takePictureUrl":[],"type":"takePicture"}],[],{"triggeredError":[],"type":"triggeredError"},{"motionRecognition":"None","sceneRecognition":"None","steadyRecognition":"None","type":"sceneRecognition"},{"formatResult":"","type":"formatStatus"},[{"numberOfRecordableImages":1228,"recordTarget":true,"recordableTime":-1,"storageDescription":"Storage Media","storageID":"Memory Card 1","type":"storageInformation"}],{"beepModeCandidates":["Shutter Only","On","Off"],"currentBeepMode":"On","type":"beepMode"},{"cameraFunctionCandidates":["Remote Shooting","Contents Transfer"],"currentCameraFunction":"Remote Shooting","type":"cameraFunction"},null,{"checkAvailability":true,"currentAspect":"4:3","currentSize":"18M","type":"stillSize"},{"cameraFunctionResult":"","type":"cameraFunctionResult"},null,null,{"currentExposureMode":"Intelligent Auto","exposureModeCandidates":["Intelligent Auto","Superior Auto","Program Auto"],"type":"exposureMode"},{"currentPostviewImageSize":"2M","postviewImageSizeCandidates":["2M","Original"],"type":"postviewImageSize"},{"currentSelfTimer":0,"selfTimerCandidates":[0,2,10],"type":"selfTimer"},{"currentShootMode":"still","shootModeCandidates":["still","movie"],"type":"shootMode"},null,null,null,null,null,null,null,null,null,null,null,null,{"currentSet":false,"currentTouchCoordinates":[],"type":"touchAFPosition"}]}
好吧，我真的希望这是足够的信息。我真的希望有人可以帮助我！！！！我发现的一个类似线程是： Sony RemoteAPI delays after started Liveview 但是没有答案。谢谢你们！！！
