	offset As Long,
	length As Long,
	flags As BASSFlag,
	track As Integer
) As Integer

Parameters

memory

Type: SystemIntPtr
An unmanaged pointer to the memory location as an IntPtr.

offset

Type: SystemInt64
Offset to begin streaming from (unused for memory streams, set to 0).

length

Type: SystemInt64
Data length (needs to be set to the length of the memory streams in bytes which should be played).

flags

Type: Un4seen.BassBASSFlag
Any combination of these flags: see BASSFlag.

BASS_WEBM_DOP	Produce DSD-over-PCM data (with 0x05/0xFA markers). DSD-over-PCM data is 24-bit, so the BASS_SAMPLE_FLOAT flag is required.
BASS_WEBM_RAW	Produce raw WebM data instead of PCM. The WebM data is in blocks of 8 bits (1 byte) per-channel with the MSB being first/oldest. WebM data is not playable by BASS, so the BASS_STREAM_DECODE flag is required.

track

Type: SystemInt32
The track to play from the file... 1 = first, 0 = first playable track. When requesting the first playable track, all tracks will be checked in numerical order until a playable one is found. The active track is available via the BASS_ATTRIB_WEBM_TRACK attribute.

Return Value

WebM is a subset of the Matroska file format. WebM files can contain Vorbis or Opus audio data, while Matroska also supports other codecs including AAC / AC3 / MP3. BASS includes support for Vorbis and MP3, and AAC on some platforms, but add-ons are required (loaded via BASS_PluginLoad) to support other codecs, eg. BASSOPUS for Opus. Not all Matroska features are supported but most Matroska files should be playable.

To stream a file from the internet, use BASS_WEBM_StreamCreateURL(String, Int32, BASSFlag, DOWNLOADPROC, IntPtr, Int32). To stream from other locations, see BASS_WEBM_StreamCreateFileUser(BASSStreamSystem, BASSFlag, BASS_FILEPROCS, IntPtr, Int32).
