StoreAutoTune Method

Summary

Saves the fine-tuning information for all channels.

Syntax

C++/CLI

public void StoreAutoTune()

public: 
void StoreAutoTune();

Remarks

Saves the fine-tuning information for all channels. "Fine tune" each channel available in a given area using the AutoTune method and generate a table of channel information. When all of the channels have been "fine tuned", then call StoreAutoTune to store all of the channel information. For more detailed information, refer to the Microsoft documentation for IAMTVTuner.StoreAutoTune.

Example

using Leadtools; 
using Leadtools.MediaFoundation; 
using LeadtoolsMediaFoundationExamples.Fixtures; 
 
 
public bool _result = false; 
public CaptureCtrlForm _form = new CaptureCtrlForm(); 
 
public void AutoTuneExample() 
{ 
   // reference the capture control 
   CaptureCtrl capturectrl = _form.CaptureCtrl; 
 
   try 
   { 
      // try set the analog video capture device, use your device name here 
      if (capturectrl.VideoDevices["Analog"] != null) 
         capturectrl.VideoDevices["Analog"].Selected = true; 
 
      // reference the TV tuner interface 
      TVTuner tvtuner = capturectrl.TVTuner; 
 
      // Check if TV tuner is valid 
      if (tvtuner != null) 
      { 
         // get the min and max channel info 
         int minChan = tvtuner.ChannelMin; 
         int maxChan = tvtuner.ChannelMax; 
 
         // select a channel between min and max to auto tune, do this for as many channels as desired 
         int tuneChan = 25; 
         int ok = tvtuner.AutoTune(tuneChan); 
 
         // if we auto-tuned successfully, store the info 
         if (ok != 0) 
         { 
            // store the auto tune information 
            tvtuner.StoreAutoTune(); 
            // set the result to what we expect 
            _result = true; 
         } 
      } 
   } 
   catch (Exception)
