    Default Problems with video recording

    Hello

    I have some problems with video recording with LiveStreamRecord module

    Let me describe problem step by step

    1. I change a little videoChat sample. Now I use it to publish stream from webcam

    2. I unstall the LiveStreamRecord module and correclyly (I hope) change Application.xml of the videoChat sample.

    3. I start videoChat sample and start t publish stream from webcamera

    4. I start liveVideoStreaming sample. And try to record the stream from webcamera.

    5. All looks good - but as the result I receive the flv file in content folder with 0 length

    Here is my Application.xml

    Code:
    <Root>
	<Application>
		<!-- Uncomment to set application level timeout values
		<ApplicationTimeout>60000</ApplicationTimeout>
		<PingTimeout>12000</PingTimeout>

    Are there any errors/warnings in the logs? Are you running at least Wowza 2.0.0.04 (which is required)?
