Hi,

I have recently downloaded the evaluation software from www.leadtools.com. I want to convert the live video which is coming from HIKVISION DVR to .lbl(DVR) playable format. I am trying to achieve the same using the following code-

convertCtrl.SourceFile = "rtsp://admin:12345@192.168.1.8:554/Streaming/Channels/101?transportmode=unicast";
convertCtrl.TargetFormat = TargetFormatType.DVR;
convertCtrl.TargetFile = "D:\\Capture123";
convertCtrl.VideoCompressors.Selection = -1;
convertCtrl.Preview = false;
ILMDVRSink dvrSink;
dvrSink = convertCtrl.GetSubObject(ConvertObject.Sink) as ILMDVRSink;
if (dvrSink != null)
{

double buffSize = 200 * 1024000;
int fileCount = 20;

dvrSink.StartChangingAttributes();
dvrSink.FolderCount = 1;
dvrSink.SetBufferSize(0, fileCount, buffSize);
dvrSink.StopChangingAttributes(false);
}
convertCtrl.StartConvert();

But I am getting an Error "LTMM Error: No combination of filters could be found to render the stream." on playing the .lbl file using player. Please guide me to resolve the issue.

Hello Himanshu,

The issue here is likely due to you not using a compression, and choosing to use DVR as the TargetFormatType.

To fix this, please try using the following code:

         convertCtrl.SourceFile = "rtsp://admin:12345@192.168.1.8:554/Streaming/Channels/101?transportmode=unicast";
         convertCtrl.TargetFormat = TargetFormatType.DVRTransport;
         convertCtrl.TargetFile = "D:\\Capture123";
         convertCtrl.VideoCompressors.H264.Selected = true;
         convertCtrl.Preview = false;
         ILMDVRSink dvrSink;
         dvrSink = convertCtrl.GetSubObject(ConvertObject.Sink) as ILMDVRSink;
         if (dvrSink != null)
         {

            double buffSize = 200 * 1024000;
            int fileCount = 20;

            dvrSink.StartChangingAttributes();
            dvrSink.FolderCount = 1;
            dvrSink.SetBufferSize(0, fileCount, buffSize);
            dvrSink.StopChangingAttributes(false);
         }
         convertCtrl.StartConvert();
