Chapter 5 Cisco Hinter for RTSP
Procedures
Restrictions
RTSP Variants
• There are many variants of RTSP and we support only one of them. You must use RTP over RTSP,
which is also called RTP over TCP or Interleaved TCP. In this variant, RTP, RTCP, and RTSP data
stream together over one logical port—typically, port 554.
• Our RTSP does not support live streaming (multicast or unicast) in this release.
• Our RTSP does not support “trick mode.” This means that you cannot pause video during playback,
fast-forward through it, or fast-rewind through it. You can merely start or stop playback.
Darwin Streaming Server
• DSS cannot read any file whose file size is greater than 2.1 GB. You must split such large files into
smaller ones before you derive hinted MOV output from them.
• Although DSS is an open source streaming media platform and available for multiple operating
systems, we have tested DSS on Linux exclusively.
Cisco Hinter
• Cisco Hinter software is available for Windows and Linux, exclusively.
• We do not support any other hinter.
• We do not support playback of hinted files that you output from any other hinter.
Protocols
• We do not support User Datagram Protocol (UDP).
• We do not support Session Announcement Protocol (SAP).
• We do not support Session Description Protocol (SDP) or its announcements.
