BassWmaBASS_WMA_EncodeWrite Method (Int32, IntPtr, Int32)

BASS.NET API for the Un4seen BASS Audio Library

Encodes sample data, and writes it to the file or network.

This overload uses an IntPtr to point to the memory block containing the data.

Namespace: Un4seen.Bass.AddOn.Wma
Assembly: Bass.Net (in Bass.Net.dll) Version: 2.4.17.5

Syntax

[DllImportAttribute("basswma")]
public static bool BASS_WMA_EncodeWrite(
	int handle,
	IntPtr buffer,
	int length
)

<DllImportAttribute("basswma">]
Public Shared Function BASS_WMA_EncodeWrite ( 
	handle As Integer,
	buffer As IntPtr,
	length As Integer
) As Boolean

Parameters

handle: Type: SystemInt32
The encoder handle.
buffer: Type: SystemIntPtr
The buffer containing the sample data.
length: Type: SystemInt32
The number of BYTES in the buffer.

Return Value

Type: Boolean
If succesful, is returned, else is returned. Use BASS_ErrorGetCode to get the error code.

Remarks

The WMA codec expects 16-bit or 24-bit sample data depending on the BASS_WMA_ENCODE_24BIT flag, but BASSWMA will accept 8-bit, 16-bit or floating-point data, and convert it to the appropriate format.

There is generally no need to call this function if the BASS_WMA_ENCODE_SOURCE flag has been set on the encoder, as the encoder will automatically be fed the data that its source BASS channel produces.

ERROR CODE	Description
BASS_ERROR_HANDLE	handle is not valid.
BASS_ERROR_MEM	There is insufficient memory.
BASS_ERROR_UNKNOWN	Some other mystery problem!

Examples

Stream what you are recording using a system-chosen port, and allowing up to 5 clients:

Copy

private RECORDPROC _myRecProc;
...
if ( Bass.BASS_RecordInit(-1) )
{
  int enc = BassWma.BASS_WMA_EncodeOpenNetwork(44100, 2, BASSWMAEncode.BASS_WMA_ENCODE_DEFAULT, 
                    128000, 0, 5);
  _myRecProc = new RECORDPROC(MyRecording);
  int recHandle = Bass.BASS_RecordStart(44100, 2, BASSFlag.BASS_DEFAULT, _myRecProc, new IntPtr(enc));
}
...
private bool MyRecording(int handle, IntPtr buffer, int length, IntPtr user)
{
  if (length > 0 && buffer != IntPtr.Zero)
  {
    // write the recorded data to the encoder
    BassWma.BASS_WMA_EncodeWrite(user.ToInt32(), buffer, length);
  }
  return true;
}

Private _myRecProc As RECORDPROC
...
If Bass.BASS_RecordInit(-1) Then
  Dim enc As Integer = BassWma.BASS_WMA_EncodeOpenNetwork(44100, 2, BASSWMAEncode.BASS_WMA_ENCODE_DEFAULT, 
                               128000, 0, 5)
  _myRecProc = New RECORDPROC(AddressOf MyRecording)
  Dim recHandle As Integer = Bass.BASS_RecordStart(44100, 2, BASSFlag.BASS_DEFAULT, _myRecProc, New IntPtr(enc))
End If
...
Private Function MyRecording(handle As Integer, buffer As IntPtr, length As Integer, user As IntPtr) As Boolean
  If length > 0 AndAlso buffer <> IntPtr.Zero Then
    ' write the recorded data to the encoder
    BassWma.BASS_WMA_EncodeWrite(user.ToInt32(), buffer, length)
  End If
  Return True
End Function
