Installation / Using Screamer EX

Q: An error is received while installing. After that, the installation completes, but when starting Screamer EX, 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 EX into Minimal Mode? The normal mode takes up to much space
A: Unlike Screamer, Screamer EX doesn’t have a minimal mode. Our suggestion would be to just minimize the entire window

Q: I have saved a configuration in another file. However, Screamer EX tells me it can’t find it
A: Screamer EX will look for the configuration file in the directory it was started from. By default, Screamer EX will be started from Documents\Screamer EX Files. You can change this, by changing the ‘Start In’ directory in the shortcut thats starts Screamer EX. 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 EX.

Multicasting

Unfortunately, Screamer EX does not support multicasting.

Broadcasting

Q: How do I receive broadcasts with Screamer EX
A: Make sure that the SDP is set correctly. Bind Screamer EX to rtp://0.0.0.0:[portnumner you set in the source]. 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: Screamer EX 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

Also, check if the sample rate set in Screamer EX, matches that of the source.

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

Q: I have multiple Screamer EX’ using the same source and I experience occasional ‘rattle’
A: If you’re using Screamer EX in a virtual environment, using a virtual card (i.e. Virtual Audio Cable or Flexconnect) as output, make sure that the sample rate is matching as the source (for instance: 44,1Khz).
