I am using flash to publish webcam stream using H264 , but some times viewer side flash shows black screen even though stream connects to FMS is there a way to know if stream has started capture frame if not black then continue else reconnect . A way to find its black screen or not .
you should use events from NetConnection and NetStream to see if connections is persistent
but! if you have black screen, usualy it happens because of device, if device is streaming without problem and connection is lost on viewer's side then you should see latest frame. And, you are using stage 3d video ? if yes, then you should know, sometimes there are troubles with it.

I'm using JW Player to live stream content onto a web page. The player is backed by an open-source library called cine.io.
My issue is that the player falls back to an HTML 5 video element for all mobile web, both on iPhone and Android. There are some differences between the flash solution of JW Player and HTML5 - notably that if a live stream starts, then stops, then restarts, the video element will not pick up the restarted stream.
This is a problem since streams often drop in and out - and the flash solution does pick up the restarted stream.
I tested a bunch of listener methods on the video and the only one that signalled that the stream had ended was a "time update" listener:
$video.on('timeupdate', function(){
//Do something
});
However none of my attempts to re-open the stream have been effective.
Is this even possible? Can anyone provide pointers?
Would an example like this work?

I created a video stream recording application that works fine except the recorded FLVs are corrupt a little bit. :) If I open an FLV in VLC player everything is green but getting "clean" when changes occur. And especially at the beginning of the video is breaking up. (I use Red5 1.0)
For pre-recorded streams, the keyframes are already encoded into the file and they cannot be changed. If you're serving a live stream, the keyframes need to be set in the application that is encoding the live stream (for example, Flash Media Live Encoder).
I'm using the flvplayback component in an AS3 movieclip. I do have the source defined in the compontents properties to a video hosted on Amazon s3.
Now the problem is as soon as the swf loads in a browser it starts downloading/buffering the video even though it's not set to autoplay.
Is it possible to only have it start downloading if the play button is clicked (I do have a custom play button hooked up to player via AS3)? I have 3 separate video players in the swf each with fairly large videos and I don't really want to burn through a ton of bandwidth especially if the user only plays one video.
Thanks!
I haven't used the flvplaybackcomponent, but I'm assuming as soon as you specify a url, it'll start downloading. Try either not setting that until it's been interacted with, or -- do what everyone else does -- place an clickable image on top, then once that's done, create your video player.
I need to be able to continue rendering a SWF file whilst it is off screen or minimized. Taken from the adobe website: "This is an automatic feature in Flash Player since version 10.1. Flash Player minimizes processing when SWF content goes off-screen."
I have extensively searched around for a solution on this. One solution suggested was to use the HTML parameter "hasPriority" and set it to true which will ensure some things are not paused. SWF content will stop rendering regardless of this when off screen or hidden.
Does anyone know if it is possible to disable this automatic feature so my SWF will continue to render off screen?
Thanks in advance for any help.
The flash virtual machine is specifically designed so that, while viewing flash in the browser, the VM is paused when the instance of the player loses window focus. This is necessary functionality in order to... well.. keep flash from utterly destroying your computer, forcing it catch ablaze and send it to the computer underworld. Just imagine what would happen if you had 3-4 flash sites open and rendering off screen on your tablet. It would die a horrible death. You cannot override this functionality.
I have a simple video player set up that streams from a flash media server. The video plays fine, but the majority of the seek commands send it back to the first frame of the video. If I don't use flash media server it will seek to any point which has already been loaded.
Any ideas what could cause this?
Try and download jw player from here http://www.longtailvideo.com/players/jw-flv-player/ and test if it works with that player. The problem could lay with the streaming server.
the majority of the seek commands send
it back to the first frame
What happens with the rest? - Do they work or does nothing happen?
The problem was I was checking the FLVPlayback playing property to see if I wanted to call play after the seek (The video didn't auto-play, and I wanted it to play if you seeked). The playing property however is set to false after a seek call till it is done seeking apparently. This resulted in play being called every time, which reset the playhead to the start.
