HTTP Output Screen
HTTP Path
For
HTTP Path
field, use the virtual keyboard (see page 6) to set a virtual path that uniquely
identifies this stream. The path designation appears in the URL following the address and
port. Helix Broadcaster adds an
.sdp
file extension to the path name automatically.
Bind Port
In the
Bind Port
field, Helix Broadcaster automatically selects a port where the HTTP stream
will be available. You can use the virtual keyboard (see page 6) to set a different port value. In
general, you can use any open port, and ports in the range
2000
to
64000
are recommended. Do
not
use any of the following reserved ports:
80, 81, 88, 443, 444, 554, 1935, 4443, 25599
Note:
If you are creating multiple outputs, each output stream must use a
different port unless you set a unique HTTP path for each stream.
Interface
In the
Interface
drop-down, select the IP address where Helix Broadcaster makes the HTTP
stream available. Typically this is the
WAN
port, which is the main IP address. If you have
configured the secondary Ethernet port using the browser interface (see page 7), you can
choose the
LAN
address or select
All
.
Note:
Typically you do
not
use the
Local Adapter
setting, which is the loopback
address (
127.0.0.1
).
Request URL
The HTTP request URL combines the IP address of the interface, the bind port, and the HTTP
path along with the
.sdp
file name. For example:
http://10.124.4.113:7880/streampath.sdp
HLS Output
With the
HLS - HTTP Live Streaming
output method, Helix Broadcaster encodes a series of
transport segments (file extension
.ts
) that are indexed by a playlist (file extension
.m3u8
). After
the HLS client requests and receives a generated playlist, it requests the individual transport
segments. All file delivery takes place using HTTP.
