I can see some streaming media,
but not others?
Some offices have firewalls or
proxy servers which are between your computer and the Internet. If this
is your case, you may need change your player protocol settings. Much
of this depends on a combination of the version of your player, whether
the content is live or on-demand archives, and the configuration of
your firewall. So the best thing to do is try some tests.
Media Player will attempt to stream audio and video to you using several
protocols. In order of best performance
to worst they are: UDP, TCP, and HTTP. If your firewall will allow UDP
content through to you this is the best option, then TCP, then HTTP.
To ensure you have all protocols available, follow these steps
Windows Player 6.4
- In the Windows Media Player click
on Options from the View dropdown. Select Advanced, Streaming Media,
Change. Find the dialog box called Protocols.
- Check Multicast, UDP, TCP, and HTTP, but do not specify
a UDP port to use.
- Click OK
Windows Media Player 7 and above
- In the Windows Media Player click on Options from the Tools dropdown. Select the Network tab.
- Check Multicast, UDP, TCP, and HTTP, but do not specify
a UDP port to use.
- Click OK
If this doesn't work you will need
to either connect to the broadcast site from outside of the firewall
or ask your MIS department to open a port, which supports audio & video
streaming. Your MIS department can support the following standard ports:
(The transports are listed starting with the best quality transport
but hardest to implement on a firewall)
- Windows Media UDP- requires
clients from inside of the firewall to be able to access server TCP
port 1755, UDP data channels are assigned dynamically using ports
1024-5000
- Windows Media TCP- requires
clients from inside of the firewall to be able to access server TCP
port 1755, TCP data is sent over port 1755.
- Windows Media HTTP- requires
clients from inside of the firewall to be able to access server TCP
port 80, TCP data is sent over port 80.
Why doesn't the audio/video play?
It is possible that the server is
down or the links to the media are wrong. It could also be network congestion
that is causing the player to time out. Keep trying, or try again later.
Why does the media stop, and the
player reads "buffering"?
Buffering is when the player stores
a portion of the stream prior to being played. It does so in case the
bandwidth of your connection gets congested, it can continue playing
until the congestion passes. However, if your connection is too slow,
you will experience buffering through out the presentation. Either,
wait until your internet connection improves or set your player to recieve
a smaller stream. This is done by going to the "Tools" tab, and selecting
"Options". Select the "Performance" tab and from here you can adjust
your connection speed. This speed should never be set higher than your
actual connection. However, if your connection is experiencing a loss
in bandwidth, adjust the drop down menu to be one selection slower than
your current abilities. If the server has a lower bandwidth version
of the media file, you will now be streamed it. If it is still buffering
frequently, your connection to the internet is not capable of currently
supplying the stream. Try it again later.
Why does the video look poor?
This problem is usually associated
with certain video card drivers that have difficulty with some features
that the player utilizes. In many cases, simply updating the drivers
for your video card will correct the problem. Following these additional
steps may help to receive the best possible video image:
- Set your monitor to millions
of colors
- Close all other applications
on your computer
- Do not resize the video window
Why does the video look choppy?
One thing that may help with the
stream is increasing the buffer size. This allows the computer to store
more of the media prior to playing which will make up for network congestion.
- Open Windows Media PLayer
- Go to the "Tools" menu and select
"Options"
- Go to the Performance tag, under
the Network Buffering section increase the time that is allowed for
buffering.
- Click on "Apply" and "OK".
Will clearing my computer's cache
solve my audio/video problem?
The browser stores temporary internet
files in it's cache, this allows your browser to avoid downloading pages
that have already been viewed. Before you view a webcast, so that you
are sure you are viewing the most recent media file, clear your cache
by following these instructions:
Netscape Navigator 3.x:
- Go to "Options" in the top menu
bar of your browser
- Select "Network Preferences"
- Select the "Cache" tab
- Click on the "Clear Memory Cache
Now" button
- Reload/refresh your browser
Netscape Navigator 4.x:
- Go to "Edit" in the top menu
bar of your browser
- Select "Preferences"
- Click "Advanced" in the left
column
- Select "Cache" under "Advanced"
- Click Clear Memory Cache and
Clear Disk Cache then select "OK"
- Reload/refresh your browser
Microsoft Internet Explorer 4.x:
- Go to "View" in the top menu
bar of your browser
- Select "Internet Options"
- Under the "Temporary Internet
Files" box, click on "Delete Files" and click OK
- Reload/refresh your browser
Microsoft Internet Explorer 5.x and 6.x:
- Go to "Tools" in the top menu
bar of your browser
- Select "Internet Options"
- Click on "Delete Files" and
click OK
- Click on "Clear History" and
click OK
- Reload/refresh your browser
Why can't I hear any sound? Why
is there hiss and clicks, and sometimes no sound at all?
First, make sure that your PC has
a sound card to play the audio and the speakers are turned "On", and
the volume on your speakers is turned up. Also check the volume on the
player, and from the computer are turned up. If you do have a sound
card, the content being played probably uses a compression codec that
isn't installed on your system, or the drivers might be bad or missing.
If the drivers are bad this could cause distortion and noises to be
generated during the webcast. To ensure you have the best driver for
your soundcard, go to the manufacturer's website, download and install
the latest driver. To ensure that you have all codecs currently supported,
re-install the latest version of Windows Media Player.
Windows Media Player errors: "the
specified stream type is not recognized", or the colors appear strange,
or the video is fine but there is no audio.
Are you running Windows NT? NT users who do not have permission to install
software will see the media player installation run and appear to work,
but in reality the codecs (the compression algorithm for the media file)
don't get updated which will cause problems.
When you first attempted to install
Windows Media Player if you did not have the necessary permission to
install software, or your internet security may have been set to medium
or high. This will prevent the codecs from being properly installed.
Change your internet security to LOW during the installation process,
or see your network administrator for proper installation.
