LEAD ONVIF Source

The LEAD ONVIF Source is a DirectShow filter for streaming data from an Open Network Video Interface Forum (ONVIF) server or ONVIF-enabled device. The data is streamed on an UDP port in RTP packets conforming to RFC 1889 and RFC 1890 in separate video and audio streams.

Currently, the following formats are supported:

• H264 video
• h265 video
• MPEG4 video
• JPEG video
• AAC audio
• AMR Audio
• G.711 µ-Law Audio

This filter supports the standard IFileSourceFilter interface. Use the IFileSourceFilter::Load method to let the LEAD ONVIF Source filter know where the source of the data is. Please see the Microsoft documentation for this interface for more information.

The data can be streamed in Unicast mode over UDP (default) or multicast over UDP (optional).

For information about the URLs used by ONVIF devices and additional available parameters, refer to the ONVIF Source URL Syntax topic.

This filter can block for extended periods of time waiting for data. For information on how to avoid blocking the application for extended periods of time and how to abort a pending wait, refer to the Aborting Loading From The RTSP, ONVIF, and UDP Source Filters topic.

Note: If the filter fails to connect to the media service or if authentication with the service fails, WS_E_ENDPOINT_ACCESS_DENIED will be returned.

Note: This filter requires Windows 7/Windows Server 2008 or later.
