You can attach a camera to Flex and stream video - I'm sure your camera is quite a bit more sophisticated than your typical webcam though Livedocs: http://livedocs.adobe.com/flex/3/html/help.html? content=Working_with_Video_18.html Hope this helps! :D --- In flexcoders@yahoogroups.com, Phil Heinz [EMAIL PROTECTED] wrote: Hi everyone, Can Flex 3 VideoDisplay or any other component display LIVE streaming video from any other format than FLV? We are trying to go straight to the camera from Flex. Many cameras will stream motion JPEG or MPEG4 for instance. Second question - does anyone know of a camera that streams FLV? Thanks! Phil
[flexcoders] Re: Streaming Video to Flex
Thanks Nathan. Problem is, camera is not attached to computer with the Flex app. I want one of 10 Flex apps around the Intranet to be able to attach to any camera's stream, and I don't want to use FMS. I have looked high and low and can't find a camera that puts out FLV. And from what I gather from Flex, streaming can only be done from an FMS source or some other software that supports RTMP. Any thoughts?

[flexcoders] Re: Streaming Video to Flex
My only suggestion would be to look into the messaging service. I don't know that that will solve your issue though - but there are examples around which show how to create a video conferencing application using Flex messaging service. Otherwise you may be stuck with having to use FMS (or some other service of the sort)... --- In flexcoders@yahoogroups.com, Phil Heinz [EMAIL PROTECTED] wrote: Thanks Nathan.

Re: [flexcoders] Re: Streaming Video in Flex using Windows 2003 Server
Hi Don, In a Flex/AIR app, the simplest way to do load video is using the component mx:VideoDisplay You can just copy the example in the docs here: http://livedocs.adobe.com/labs/flex3/langref/mx/controls/VideoDisplay.html#includeExamplesSummary Note that as written, the doc example is for a progressive download via http. Specifically note the value being passed on the source= property: source=assets/phone.flv Since no protocol is specified in this example, http is implied by the relative reference to the flv file. (This same, simple component also supports streaming. If the flv was being streamed the protocol RMTP would need to be included in the URI passed to the source= property.) If you copy the example in the docs into your project, you will need the absolute path to the example flv file. So just replace the URI passed to the source= property to the following: source= http://examples.adobe.com/flex2/inproduct/sdk/explorer/controls/assets/phone.flv Of course, you can also specify any valid URI to any valid flv (including your own ;-) Please post back if you have any follow-up questions. hth, g
Re: [flexcoders] Re: Streaming Video in Flex using Windows 2003 Server
ya u can use video display , but if your using fms/rtmp combination it is better to use Video object then attach netstream to it. It will give more control to functionality / interactivity and offcourse errors. It is good idea to control the played video form FMS server side using streams instead of using client side logic. For streams part u can refer to this http://www.adobe.com/devnet/flashmediaserver/articles/learning_fms2_excerpt/learning_fms2_ch09.pdf On Feb 1, 2008 1:17 PM, greg h [EMAIL PROTECTED] wrote: Hi Don, In a Flex/AIR app, the simplest way to do load video is using the component mx:VideoDisplay You can just copy the example in the docs here: http://livedocs.adobe.com/labs/flex3/langref/mx/controls/VideoDisplay.html#includeExamplesSummary Note that as written, the doc example is for a progressive download via http.
