LEAD RTSP Source

Show in webframe

The LEAD MPEG2 Transport RTSP Source is a DirectShow filter for streaming data from a RTSP server. The data is streamed on a 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
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 RTSP Source filter know where to read the data from. Please see the Microsoft documentation for this interface for more information.

The data can be streamed in Unicast (default), multicast (optional) or tunneling over HTTP mode. This is specified using the 'Transport' option through the string passed to IFileSourceFilter::Load.

See the RTSP Source URL syntax topic for a discussion about the URLs used by RTSP servers. The topic also contains a table with sample URLs for servers that LEAD has tested, together with the video and audio compressions used by each server.
