Upgrade to version 1.3.0

Version 1.3.0 uses a extended version of screamer.inf. This means that the old screamer.inf cannot be correctly read by version 1.3.0. If you need to upgrade to version 1.3.0, please first uninstall the old version and install version 1.3.0. After that, before starting Screamer, please edit all available Screamer configuration files to add two lines to each. Please see screenshot below for an example. The added lines are the X and Y position of the software on the screen after startup.

Installation / Using Screamer

Q: An error is received while installing. After that, the installation completes, but when starting Screamer, it will crash right away/
A: This is due to an error while registering a vital component for Screamer. Always run the installation with elevated rights (i.e as an Administrator).

Q: How do I put Screamer into Minimal Mode? The normal mode takes up to much space
A: Click on the button in the down-left corner of the screen

Q: I have saved a configuration in another file. However, Screamer tells me it can’t find it
A: Screamer will look for the configuration file in the directory it was started from. By default, Screamer will be started from Documents\Screamer Files. You can change this, by changing the ‘Start In’ directory in the shortcut thats starts Screamer. If you do, make sure that the configuratio file you wish to use is in that specific directory. Also, you can parse the complete path to the configuration file as a commmand line parameter when starting Screamer

Multicasting

Unfortunately, Screamer does not support multicasting.

Broadcasting

Q: How do I broadcast to multiple Exstreamers
A: Set the URI in Screamer to the broadcast-address for your IP-range (i.e. 192.168.1.255 or 172.20.0.255) and a portnumber (i.e. 4444). Make sure that the SDP is set correctly. Configure the Exstreamer for push rtp, using rtp://0.0.0.0:[portnumner you chose]. Save/Apply the settings and press Start.

Q: What is the difference between broadcasting and multicasting?
A: Broadcasting usually creates more network traffic because it literally ‘broadcasts’ the data to all addresses in the range. Multicasting is a group of hosts using the same multicast-address, which should result in less traffic. However, multicasting is far more complex to setup and often requires reconfiguration of switches and routers to allow the traffic to pass. Also, Screamer currently does not support multicasting.

Troubleshooting

Q: My Exstreamer is giving me nothing but ‘rattle’
A: Most likely, the SDP-configuration used is wrong. Try the config below. If this one works, the Exstreamer is configured properly.

v=0
m=audio 0 RTP/AVP 14
a=rtpmap:14 mpa/44100/2

Q: Everything works, but after about 30 seconds, the streaming stops.
A: This has to do with RTCP Timeout. When enabled, Screamer will periodically check if the configured receiver is actually online. If not, the streaming stops. If this happens when the receiver is online, uncheck RTCP Timeout and restart Screamer.
RTCP Timeout

Q: I have multiple Screamers using the same input and I experience occasional ‘rattle’
A: If you’re using Screaming in a virtual environment, using a virtual card (i.e. Virtual Audio Cable or Flexconnect) as input, make sure that all the Screamers are using the same sample rate (for instance: 44,1Khz). Ideally, this sample rate matches the sample rate of the audio card used.
