Password Protection
Enter the password if it is a protected stream. Streams can be password protected in a VBrick
Appliance in the SAP Transmit or Encoder Configuration section of a VBrick Appliance
(refer to the
VB1000-2000-3000 or VB4000-5000-6000 User Guide for instructions on
how to configure SAPs). StreamPlayer Plus can record password-protected streams if the
password is known. When attempting to record a stream that has been password protected,
the user will be prompted to enter the configured password. Two specific categories shown
below and set in the VBrick appliance affect StreamPlayer Plus recording. (See the
StreamPlayer Plus Administrator Guide for more information.)
• norecord – The stream cannot be recorded.
• norecord=<password> – StreamPlayer prompts the user for a password.
MPEG-4 Hinting
If the stream is MPEG-4, the Hint for live streaming box will be selectable. (For other MPEG
and Windows Media types this box will not be visible). Hinted files contain reorganized data
that facilitates streaming over the network. If the
Hint for Live Streaming
box is checked,
StreamPlayer Plus embeds certain information within the files, making it easier for a server to
read and send pre-formatted packets. Hinting eliminates server-side preprocessing, reducing
the CPU load, memory requirements, and the amount of disk access on the server.
Note The file name extension for MPEG-1 and MPEG-2, is .mpg. For MPEG-4 it is
.mp4. For Windows Media it is .wmv.
Hint for live
streaming Hinting a file takes place after the file has been recorded. It is
recommended that the hinting be complete before the recorded file is
accessed. If the recorded file will be streamed from a Video on
Demand server, it is recommended that Hinting be selected.
