MF_SINK_WRITER_DISABLE_THROTTLING attribute

Specifies whether the sink writer limits the rate of incoming data.

Data type

UINT32

Get/set

To get this attribute, call IMFAttributes::GetUINT32.

To set this attribute, call IMFAttributes::SetUINT32.

Remarks

By default, the sink writer's IMFSinkWriter::WriteSample method limits the data rate by blocking the calling thread. This prevents the application from delivering samples too quickly. To disable this behavior, set the MF_SINK_WRITER_DISABLE_THROTTLING attribute to TRUE when you create the sink writer.

Use this attribute with the following functions:

• MFCreateSinkWriterFromMediaSink
• MFCreateSinkWriterFromURL
