LEAD SSF Writer

The LEAD SSF Writer can be used to create Microsoft Smooth Streaming video files (.ISMV files) based on the ISO/IEC 14496-12 ISO Base Media File Format described by JTC 1/SC 29.

The LEAD SSF Format is the format created by Microsoft to create variable bitrate and resolution streaming video. See the LEAD ISO Demultiplexer page for more details on LEAD support of SSF streaming playback.

The LEAD SSF Writer does not support every video and audio compression. The following compressions are supported:

The smooth streaming video files can be streamed using the Media Streaming SDK or an IIS Windows Services Server.

This filter supports the standard IFileSinkFilter Interface (UDP, RTSP, MMS) interface. Use the IFileSinkFilter::SetFileName method to set the output folder name. Please see the Microsoft documentation for this interface for more information.

This filter can write one or more video streams, which can be configured using the ILMSsfWrtVideoStream interface. The filter will write only one audio stream, configurable using the ILMSsfWrtAudioStream. Both of these interface are obtained from the ILMSsfWrt interface. See the Using the LEAD SSF Writer topic for more details.
