Create/modify Flash Video Stream Before Streaming Via RTMP?
Jan 4, 2010
Usually, flash streaming is done by capturing webcam video/audio and streaming using NetConnection and other objects to servers like FMS,Red5,Wowza etc.I haven't found any example on how to create your own stream of images and stream as a video to the server.I know it would be possible to convert the image to bytes and send via SharedObjects. Then decode on server and create a video file on the server (e.g. using ffmpeg), but I would rather do it in realtime on the client side if possible.

Quick question - I have the following setup:
(1) An ec2 instance with an SWF on it - this SWF plays streaming video - i.e. is a video player like JWPlayer
(2) A streaming video distribution set up via Cloudfront
If I stream the the video via RTMP from Cloudfront to the SWF (which is on ec2) - would I incur charges for data transfer into the server (i.e. for data being read by the SWF) and out of the server (i.e. for data being displayed by the SWF to the user) on account of streaming the video to users (assuming that data transfer into and out for the server is being charged for)?

Writing RTMP Streaming Server for streaming AVC+AAC video. And it works fine with rtmpdump. But I can't force it to work in flowplayer and other flash video players.The message sequence after handshake is similar to FMS / RED5 / erlyvideo / haxevideo servers: I've tried a lot of variations.
From Chrome debug console I can see, what all negotiating messages passed to the flowplayer. The last one is onMetaData. And after this the working sample (rtmp://flash.tvwmedia.net/LiveVideo//Live300) gets NetStream.Buffer.Full. And streaming from my server don't get it.
I'm starting with AVC Header message, containing sps/pps. After it first AVC picture passed. After - AAC header and AAC sample. And then AVC/AAC samples. This dumped OK by rtmpdump - I have working flv on exit. But flowplayer and others does not work.

I am trying to publish a video to an RTMP Server but it doesn't publish. It might be a pre-release bug. I am able to play a NetStream but not able to publish one. Is there a sandbox issue? I'm not sure. Because, the FMS RTMP Server will not let a client connect unless it has been downloaded from the same host as the server (something like a sandbox condition)

At a certain point in the app flow, a m4v video is streamed from a remote location via rtmp. This works well, except for two little problems:
1. In very rare cases, the video starts playing, but you see no images and only hear the audio. Seems like this happens more often with Chrome, but that is only a guess.
2. In the first frame or so of the video, you hear a noise in the audio. It really is very short, but still a nuisance. This chirp is not there when viewing the same video with VLC or QuickTime player. It IS there when viewing with the Windows Media Player.
Are there any known problems with codecs and the flash as3 video streaming (via NetStream/NetConnection)? The video is composed by using the ffmpeg library (one mess of a library, I can tell you...) to bring together a live-rendered video (using a 3D Engine) and a pre-created *.wav (which does not have the chirp).

I am developing an application in Flash that runs locally and it uses FMS 4.01, locally. I have been using adobe FMS 4.01 for months with no problem. Today I cannot connect to my server and I cannot even play the sample video on the Flash Media Server Start Screen. The sample video for the http plays after I changed the permissions for flash, but rtmp does not play. I have reinstalled the server; 3.5, 4.0 and 4.01, none of them will connect to rtmp. I receive this error on the flash media server start screen that says "the connection timed out".

I am building a flash media player for an live audio stream. The server is set up to stream from a url that looks like so: [URL]. The instructions I have found say to first set the directory:
nc.connect("rtmp://ourwowzaserver.net:80/ourfiledirectory");
And then later play it:
nc.play(mp3:thefilename)
This works when we have discrete filenames on the server (thefilename), but the live stream is not a file - rtmp://ourwowzaserver.net:80/shoutcast. How in the heck do I get .play to play it?

I am trying to connect to an rtmp site using flash builder 4. I have created a class to handle the connection. This code works (traces a connection error) if connection.connect(null); but if i try to put an rtmp site in the connection, it doesn't do anything. I have it scripted that if the connection fails it should trace and error message but it just seems to stop. any thoughts?
ActionScript Code:
package com.streaming.video

I can stream video RTMP just fine in JW Player by LongTail Media. The Pause seems to work, however using Windows 7's Resource Monitor I can see that the player continues to download data when the video is paused, it downloads for about 60 seconds (and does not seem to be longer for longer videos). I have found the same using the examples on longtailmedia's website, so I know it is not something I have done.
I want a way to pause the video and have it stop downloading, this will save us lots of bandwidth. But also have it continue where it left off if play is pressed again.
I checked the logs on our wowza media server, which indicates that the player actually waits 60s before it sends the pause command to the server.
LongTail's support say that the pause functionality uses the built in NetStream class and its behaviour is out of their control.
I have tested flowplayer online examples, and a couple of Adobe / OSMF examples and they all continue to download for 60 seconds after the video is paused.
A way to get this working in JW player would be best, but Are there any flash players that will stop downloading while paused?
If this is not possible with RTMP are there any technologies that will do this with a flash player?

We are attempting to transcode some video to a format suitable for our Flash Streaming Server. In the past we have used Adobe Media Encoder (AME) CS4, but we are working with *.VOB files this time, and AME CS4 does not support them. We are attempting to use Handbrake now, as it has great support for h.264 and MP4 files. Unfortunately while the files play wonderfully on our local machines, they do not stream from the Flash streaming server over RTMP. The files come out of Handbrake with a *.m4v extension. Our old files out of AME CS4 are *.MP4's with h.264 and AAC audio. I can see no differences in video or audio codecs which leads me to believe it may be a container format problem. We are attempting to use Handbrake because it does an excellent job of batch encoding files and produces good quality files.

Live streaming and a buffer on a NetStream do not mix. Why? The docs don't say you can't do this.The playback gets hosed. Buffer is supposed to fill to what you set it to before playing. Instead though, about half the time, the player starts playing right away and disregards the buffer time you've set. Then you get caught in short buffering and rebuffering cycles that degrades the playback experience.
Give it a shot yourself. Here is the simplest of live streaming video players. No frills. Just connect it to your live stream by changing the defaultURL string and stream name in the ns.play() statement.
Run it in Flex debug mode. It will check and print the ns.bufferLength property every second. The buffer is set to 20 secs currently. Last time I ran it, I never made it above 2 seconds in the buffer. Player started playing right away instead of buffering the full 20 secs first. Sometimes you get to the full 20 and sometimes not.

What's the best way to check whether there is video data (or not) in a live RTMP stream? For example, if a broadcast terminates, can I auto-detect that condition, to perform some sort of "thank you for watching" behavior?Also, how can I know if a visitor somehow gets disconnected from the Internet during the broadcast? (So I can notify the visitor of the problem, and give instruction.)

I've created a player for a client in the past using their LimeLight server to stream videos and not had an issue before, however for a new client using different LimeLight server, the videos seem to be ending 3-4 secs too early.
My traces on 3 vastly different videos I tested:
metadata duration = 32 // 32 secs long, ends at 27
Stop [27.350 seconds] = 4.65
metadata duration = 17 // 17 secs long, ends at 12
Stop [12.852 seconds] = 4.148
metadata duration = 258 // 258 secs long, ends at 255
Stop [255.861 seconds]
In the video players I check for NetStream.Play.Stop then put a 'reset' type function in there. This function however triggers too early due to this strange bug. Has anyone have seen this before?
private function netStatusHandler(event:NetStatusEvent):void
{
trace("connected is: " + nc.connected );
[Code].....
The only work-around I see for this is saving the initial number I get from the metadata duration, and running a timer to constantly check for when the current ns.time matches metadata and then run my reset function.

I want users to be able to upload audio files to my server (say, over HTTP.. mechanism doesn't matter much), and then I'd like to assemble those files into a playlist and stream them out over a live RTMP stream to a Flash widget.The catch is: I'd like to begin streaming the audio files before they completely finish uploading. For example, if a user uploads an hour-long mp3, I'd like it to be able to begin playing on the RTMP stream once, say, the first minute has been uploaded.I'd like to support mp3 and AAC, and would hope to avoid re-encoding the files. Is is there a way to make this work with Wowza, Flash Media Server, or some other clever solution?

I'm building a Flash mp3 player to handle streaming mp3s served by Amazon CloudFront (which uses Flash Media Server). I'm using an FLVPlayback 2.5 component to do most of the heavy lifting (I tried an all AS3 method, but any stream automatically stopped within 5 - 10 seconds of playing). When I trace out the FLVPlayback's totalTime property, I get NaN. This is causing the seek bar to simply not work. This only seems to affect mp3s, as when I load an FLV I get a real value for totalTime. Does anyone know why this is happening

Currently, we are streaming using RTMP, but I want to switch to HLS to allow iOS devices to stream our video. I do not want to encode two separate streams though because we are operating with limited bandwidth on mobile data cards. If I stream using the livepkgr, the delay to iOS devices is about 12 seconds which is OK. However, on desktop clients, we have live scoring integrated with our video, so we cannot have a delay that long. My question is, if I connect to the same stream in a Flash client for the desktop, will the delay still be that long? Or will it stream in real time to flash clients with the delay only for iOS devices using HLS? Also, am I correct in assuming that I can do this on 1 stream, or do I need to setup a separate stream for RTMP and HLS?

I herd about RED5, but unfortunately I can't find any examples for feeding it with external source. I know RTSP is in development, but I'm thinking about (named) pipes or something like this. There is is also project named xuggle that is as far as I understand ffmpeg wrapper for Java, but I herd they have also problems with live streaming.

I'm trying to stream an audio clip via rtmp in as2. I'm not particularly attached to the method, but this is the starting point I am at below:
Code:
var s:Sound = new Sound();
var req:String = "rtmp://path/filename"; //doesn't work
var req:String = "[URL]"; //This works
s.loadSound(req, true);
I need to get an RTMP audio stream working, does anyone have any experience with this? (Also not sure if this goes in the actionscript folder or the sounds folder.

I have some questions regarding 4.5 and deciding which version we must license (FMIS or FMS). Obviously there is a huge price difference and as this is within a local network we don't require encryption or multicast. Here is the scenerio we need to stream live DVR to mac, windows browser AND iPhone/iPad and devices running Android 2.2(Froyo)+. I need someone from Adobe to help us decide.
1. I see DVR is now listed as a feature in Flash media server page. Does that mean its no longer exclusive to Flash Media Interactive server. For both http streaming and RTMP?
2. Previously in order to stream live to Adobe dynamic streaming, Flash media interactive server was required because a live segmenter had to be used. Is this still the case? Or can we just launch adobe live media encoder (FLME) and stream to flash media server.3. Related to #2 can we switch between serving streams via RTMP or dynamic streaming without changing the format of the material on disk?4.I was at a webcast for 4.x and remember being told that the latency for http live dynamic streaming was 20 seconds because of the repackaging that had to take place. Is this still true? What is the latency for iOS playback from ingest to playback?5. For the iOS playback feature do the streams have to be in Adobe dynamic streaming format or can we just stream via FLME RTMP and trust it to do the right thing?6. Does the iOS playback support DVR?7. Does the Android plugin have good support for RTMP live streaming including DVR?
