Stored
ts/mpg, mov, or mp4 files can be served using unicast RTSP/TS. Only files containing H.264
content video are supported. The recommended URL format for this use case is as follows.
Alternate URLs are available but not recommended.
rtsp://<dme_ip_address:port>/vodts/<filename.extension>
If the file is a transport stream file then the following formats can be used:
rtsp://<dme_ip_address:port>/vod/<filename.extension>
rtsp://<dme_ip_address:port>/vod/<filename.extension>?ForceTS
rtsp://<dme_ip_address:port>/vodts/<filename.extension>?ForceTS
If the file is a mov or mp4 file then the following format are acceptable:
rtsp://<dme_ip_address:port>/vod/<filename.extension>?ForceTS
rtsp://<dme_ip_address:port>/vodts/<filename.extension>?ForceTS
You can serve an available stream via unicast RTSP with the resulting URL as follows
(append “_ts” to the URL path).
rtsp://<dme_ip_address>:5544/<stream_name>_ts
Input and Output DME Streams
Out-3 > Se rv e (RTP)
The Multi-Protocol server on the DME serves live or stored content using the RTSP/RTP
protocol. You can play the stream in StreamPlayer, QuickTime, or VLC using a URL similar
to this:
rtsp://server:port/<publishing_point>
Since the Multi-Protocol server uses a non-standard RTSP port (default 5544), the port
number is required in the URL. There are two use cases for serving RTSP. Out-4 should be
used for optimal stream stability, but if many simultaneous users are expected, the equivalent
Out-3 is preferred. There are three possible protocols used for RTP serving: UDP; TCP
using RTSP interleaved; TCP using HTTP tunneling. Out-4 supports all three of these
options while Out-3 does not support HTTP tunneling. This difference may determine which
RTSP/RTP server to utilize.
Live
This output option requires no explicit configuration on the DME but is available for all live
content present on the Multi-Protocol server, whether brought directly into the server or
Pulled from the RTP server using an internal In-6. An example of a live publishing point is:
rtsp://<dme_ip_address:port>/<streamname>
Stored
There are two options for serving RTSP. Out-4 is used if the VOD content contains
MPEG-4 Part2 video or PCM audio. Since Out-4 is more generally applicable it is
recommended for this use case. Stored content is accessed using the filename of the content.
Examples of stored URLs are:
rtsp://<dme_ip_address:port>/filename.mov
rtsp://<dme_ip_address:port>/filename.mp4
