I have used JMeter to perform some loading tests on my company. Now we need to test an live stream service, but I don't know how to do that. I've made a good research so far and got nothing.
The stream is send as flash application, the type is x-shockwave-flash.
Are JMeter able to handle with RTMP? If no, what is a good alternative?

JMeter doesn't support
RTMPnatively but you can write your own sampler by extending theAbstractSamplerand using a third party RTMP library for Java, such as Red5 to handle the connection.For the latter, you can find an example plugin here: https://github.com/taktod/RtmpPluginForJmeter
