IWMPNetwork::encodedFrameRate property
[The feature associated with this page, Windows Media Player SDK, is a legacy feature. It has been superseded by MediaPlayer. MediaPlayer has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer instead of Windows Media Player SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The encodedFrameRate property gets the video frame rate specified by the content author.
Syntax
public System.Int32 encodedFrameRate {get; set;}
Public ReadOnly Property encodedFrameRate As System.Int32
Property value
A System.Int32 that is the encoded frame rate in frames per second (fps).
Note
Although the encodedFrameRate property measures the encoded frame rate in frames per second, the frameRate property measures the current frame rate in frames per hundred seconds.
Examples
The following code example uses encodedFrameRate to display the frame rate specified when the file was encoded. The information is displayed in a label, in response to the PlayStateChange Event. The AxWMPLib.AxWindowsMediaPlayer object is represented by the variable named player.
// Add a delegate for the PlayStateChange event.
player.PlayStateChange += new AxWMPLib._WMPOCXEvents_PlayStateChangeEventHandler(player_PlayStateChange);
// Create an event handler for the PlayStateChange event.
private void player_PlayStateChange(object sender, AxWMPLib._WMPOCXEvents_PlayStateChangeEvent e)
{
// Display the encodedFrameRate when the player is playing.
switch (e.newState)
{
case 3: // Play State = WMPLib.WMPPlayState.wmppsPlaying = 3
if (player.network.encodedFrameRate != 0)
{
encodedFrameRateLabel.Text = "Current Encoded Frame Rate: " + player.network.encodedFrameRate + " K bits/second";
}
break;
default:
break;
}
}
' Create an event handler for the PlayStateChange event.
Public Sub player_PlayStateChange(ByVal sender As Object, ByVal e As AxWMPLib._WMPOCXEvents_PlayStateChangeEvent) Handles player.PlayStateChange
' Display the encodedFrameRate when the player is playing.
Select Case e.newState
Case 3 ' Play State = WMPLib.WMPPlayState.wmppsPlaying = 3
If (player.network.encodedFrameRate <> 0) Then
encodedFrameRateLabel.Text = "Current Encoded Frame Rate: " + player.network.encodedFrameRate + " K bits/second"
End If
End Select
End Sub
