Streaming audio/video issues

When I attempt to play video (Hulu, YouTube, Netflix) or audio, my IPhone 5c goes into this continuous buffer mode. How can I get audio/ video to stream again?

You are joking right? establish an ethernet connection?
We try not to joke on the forums. If you are using 802.11n 5 GHz, that might do it if the Blu-Ray player and Time Capsule have close to a line-of-sight relationship. If 5 GHz won't do what you want, that tells you that the connection has insufficient bandwidth to provide the connection quality that you need.
If you are using regular "n" wireless at 2.4 GHz, ethernet will have about 8 times the bandwidth capability than wireless. Using 5 GHz, ethernet will have 3 times the bandwidth of wireless.
You may not want to consider ethernet, but it's hard to argue with physics. I've tried to stream high definition sources over a very good wireless network, but have not found a way to do this and obtain the performance that I want. But, perhaps another user has found the answer and will post to tell us about his workaround. I will be watching this thread.

How to stream audio / video in java?

Hello.
I would live to develop a java application (JavaEE, with tomcat or JBoss) that could stream audio / video over the Internet, on a controlled matter.
First, I would have to embed a flash player, correct? Need suggestions on one, paied or free.
My questions are: How can I have the flash player stream audio to users by downloading it from a java app server, if the user has a session and is logged in, etc? (picture myspace here)
Also, how do I measure network traffic in Java? (The flash player of each user will stream the songs, I'd like to know how much bandwith is going around).
The reason that I'm asking this here is because I have no idea of which forum to ask this.
I have been a Java app developper for the past five years, so coding won't be a problem, I just don't know which API / Frameworks to turn to.
Thanks for all your help.
Regard,
Carlos.

My questions are: How can I have the flash player stream audio to users by downloading it from a java app server, if the user has a session and is logged in, etc? (picture myspace here)The same way you would authenticate any website. Usually a database and a challenge/response. If they're not logged in, then instead of writing out the content, write out a 403 status code (or do something more graceful, such as redirect them to the login page).
Also, how do I measure network traffic in Java? (The flash player of each user will stream the songs, I'd like to know how much bandwith is going around).Just keep track of how much data you send to the OutputStream.

Reporting an audio/video issue with a TV show from a Season Pass? How?

I would like to report some audio/video issues with the latest The Unit and The Seeker episodes but I can't find them in my Purchase History??? I own a Season Pass for both. Any idea how to do it? I'm lost. Thanks!

Is this the lack of audio on "Shadow Riders"? I've just got to that episode, and I tried to report the problem, but the whole series of hoops you have to jump through seems to have changed. Rather than get to the page where you add comments for the problems, it merely sends you to an internet link on apple that has no bearing on the problem.
If you open your account information (store > View my account) you can click your purchase history there. The theory is that you find your program, click the arrow next to it, then click "report a problem" and it should allow you to enter a comment, or the problem... Anyone else having this troubvle?

How to stream audio/video to real Audio Player

Hello
I am planning on doing a project on streaming audio/video onto Real Audio Player . I am very new to JMF . I would appreciate some pointers on how to start off. I ahve read the documents but am not able to get started right .
I wanted to know the following :
1. Isnt the RTP streaming streaming for live audio or video ? If I want to stream something which I have stored in my local machine then how do i do it - do i need to use RTP ?
2. I undertsand that if i need to stream the audio/video file I need to convert it to a format the Real Audio Player supports. How do i go about that ?
Any help would be greatly appreciated!!!
Thanks in advance
Shailaja

JMF doesn't have any support for Real media. Real has gone open source with their Helix Community, so maybe you could find some useful information there: http://www.helixcommunity.org

Streaming Audio/Video/Pictures to Apple TV2

I just updated my iPhone 4 to iOS 4.2.1 and have ordered an Apple TV2. Can or will the phone stream audio/video and pictures directly to the ATV2 or do I have to set the ATV2 up with my wifi router? I just downloaded the ATV2 manual, it doesn't say that the phone will stream directly to the ATV2. It does show how to connect with a wifi router though.
Thanks,

Thanks for the info guys. If video and/or pictures are moved from the Camera Roll to the Photo app they should stream with AirPlay then, correct?
photos can be streamed whilst in the camera roll.
videos would need to be in the ipod section (ie like a movie or tv show).

Streaming Audio/Video Won't Play!

Ok, I've had this dilemma for quite a while and I notice that it happens in every browser I use on my iBook. I want to listen to some streaming audio or watch streaming video and everytime it attempts to load I get a pop up saying "Cannot play back the file. The file format is invalid" This just happens usually when the streaming is Windows Media..is my Windows Media player not functioning correctly? What's going on? Any help would be appreciated. THANK YOU!

From a Microsoft Bulletin:
Cannot play back file. The file format is invalid.
In some cases, you might be able to play the file in Microsoft Windows Media Player on a Microsoft Windows-based computer, but not on a Macintosh. This occurs because Windows Media Player for Mac is parses .asx files more strictly.
This issue may occur if the .asx file contains an error, or if there is an error in the HTML coding of a Web page that contains an embedded Windows Media file.
To resolve this issue, test to determine if Window Media Player can play other .asx files. If it can, contact the owner of the Web site to have the owner troubleshoot the .asx file.

Use FMS & Actionscript to Stream Audio/Video and control (powerpoint) slides

Hi there,
My compnay provides webcasting services to numerous clients, and we currently use Windows Media Encoder as our base software for these projects.
However, I'm interested in switching to Flash Media Server, but need to figure out one issue and how to implement it in such a way like how we are currently using Windows Media Encoder.
We need a way to stream out a live audio/video feed AND have a way to control a presenter's POWERPOINT slides and have them advance by our command when streaming live.
Basically, the way we do it is we will stream out audio/video from WME and also use the encoder's SCRIPTING functions to send out a "url" from the encoder to the actual page in which the viewer is watching the live embedded stream. On that page is an embeded/internal frame which we can specify (using the id/name) that the url gets loaded, and this actually advances the slides (or more so pulls up a pre-created html page of the next slide in the person's powerpoint, which is actually a screenshot or exported image of that slide and embedded within a specific HTML file and hosted on the same server as the embedded player/html file)
Would there be a way to send out this same type of script using FMS? I've been playing around with it and notice the interface itself does not have a built in scripting function like Windows Media Encoder does. However, I did read somewhere that it supports ActionScript... but I have no clue how to implement this feature.
I am just curious how it might be able to go about doing this? Is there a way to use an [action]script with FMS and have it send out a URL to a specific frameset embedded on the same page as the Flash Media Encoder Playback?
Hopefully this make sense and that someone can point me in the right direction. Switching to FMS over Windows Media Encoder is the way I would love to go, just need to figure out how this could be done.
Would a better method be converting the powerpoint slides to a swf or flv file, embedding that file within the same page as the FMS playback, and somehow using a script to "advance" the frames/slides/scenes within that file?
I also heard something about Flash "Shared Objects" and how this could be a way of controlling a swf file remotely.....
Could anyone give me some advice and know a method that I could use to achieve this type of implementation?
Any help is GREATLY appreciated! Thanks!

FMS (the interactive version, FMIS) has complete scripting support.
What you want to do can be done with FMS, and there are a lot of ways you can approach it. Converting to .swf can be helpful, as it means you have a single resource to load rather than a bunch of individual slide images (the flashplayer can load .swf, jpg, gif, png). Rather than embedding, I'd opt to make it an external resource and load it at runtime... that would keep the player application reusable.
To get an idea of how to use server side actionscript, see the getting started portion of the FMS 3.5 dev docs
http://help.adobe.com/en_US/FlashMediaServer/3.5_Deving/
Then, see the SSAS docs for the following classes in particular:
The Client class for Client.call()
The Stream class for Stream.send()
The Shared object class
The Application class for BroadcastMsg()
The docs give some general overview for the usage of each. The best choice really depends on your deployment architecture and scalability requirements.

Unwanted synchronization when streaming audio&video

hi,
i'm streaming audio and video, both of which are created with separate Processors. i'm playing them back on the client's side with separate players on separate ports. despite all this, when i pause the audio, the video pauses too!
any suggestions?
Thanks in advance :O)

This is suposed to happen if the streams received have the same CName. I guess if you are able to send two different streams with 2 different CNames they won't synchronize. But I still don't know how to do that... :)
Also, less useful but still a fact, if you receive the streams in two different VM's that won't happen either... :)

Live streaming audio/video

I'm looking for advice on how to stream live video, full
screen at high quality 640x480 30 fps. I need to be able to carry
on a teleconference between two instances of the program, but also
support 640x480 at 30 fps. What programs might be needed (encoder?,
server?)

Hi tony45371,
The replies from in2mobile are 100% correct.
For live video, some server is required. Flash Media Server
is the required server offered by Adobe (there are competitors
including open source competitors to Flash Media Server). Also an
alternative to putting up your own Flash Media Server, may CDNs
offer Flash Media Server services. You can find a list of CDN
partners here:
http://www.adobe.com/products/flashmediaserver/fmsp/
Are your live events webcasts (e.g. 1 presenter, w/ many
attendees)? Or 2-way (e.g. multiple presenters)?
I assume that you require 2-way since your post said "I need
to be able to carry on a teleconference between two instances of
the program".
Following below are links into the browsable version of the
product documentation (adobe.com/livedocs). Easier to read PDF
versions can be downloaded here:

(Above link, in the PDF version, is in Chapter 4: Developing
live video applications)
1-WAY WEBCASTS
For live webcast events, Flash Media Server includes a free
companion program "Flash Media Live Encoder 2.5" (aka FMLE). FMLE
offers higher quality video (H.264 & VP6), and audio (MP3 and
with a 3rd party plug-in AAC). Details on FMLE here:
http://www.adobe.com/products/flashmediaserver/flashmediaencoder/
Following is a link into the product documentation on using
FMLE 2.5 w/ FMS3:

Brand new imac - streaming audio/video skips

Hey all,
I just purchased a brand new imac with snow leopard 10.6.1 on it. When I use any sort of streaming media (pandora, hulu, youtube, etc.) it intermittently slows wayyyy down and skips. I have no problems with this on my other computers (2nd gen macbook, lenovo thinkpad.) This problem occurs in both Safari and Firefox. I have tried changing the frequency channel on my router, to no avail. As a whole, the browsers are slower than I would expect them to be.
Any ideas? This is really aggravating, especially since it's so new.

10.6.2 just dropped less than an hour ago, and includes a fix for this....

+this update addresses video playback and performance issues for iMac (21.5-inch, Late 2009) and iMac (27-inch, Late 2009) computers that may occur in some situations while AirPort is turned on+

Audio/Video Issues in Tour de LC

First off, I would like thank Adobe for producing this resource.
In looking through the various pages contained within Tour de LC, I have found a couple of minor issues with regard to some of the videos presented. A co-worker had found a video that had no audio, unfortunately I am not sure which module it occurred. There is some kind of captioning in the video so it may just be that there is no audio.
In LiveCycle Overview > LiveCycle Solutions > Life Sciences > Life Sciences Demo Module, the Life Science Demo video does not sync with the audio. The video seems to stop while the audio continues.
In the LiveCycle Overview > Resources > Adobe TV section, the Videos labeled 'Service-Orientated Architecture for the Enterprise' and 'Invoking a LiveCycle ES process from an Adobe AIR application' seem to be the same video.
Again, Thank you for this great resource. I am sure it will be helpful to a great many LC users and developers.
Vive La Digital Revolution!!

Hi Ryan,
Thanks for the input and compliments on Tour De LiveCycle.
Many of the videos in TDL do NOT have audio associated with them. They simply have callouts on the screen directing the user.
On the "LiveCycle Overview > LiveCycle Solutions > Life Sciences > Life Sciences Demo" I do not see the same behavior as you do...it seems like it is ok. Maybe it has to do with the network speed.
We will fix the link on the Adobe TV to point to the correct video.
Thanks for the input!

IDS/IPS signatures to monitor streaming audio/video applications

Hi folks,
Can someone advise on the names or signatures that could be successfully used to monitor the usage of streaming applications on the network. The plan is to feed them to MARS and then create reports on streaming applications utilization to use it later for creation a security policy preventing bandwidth stealing.
Perhaps any suggestions on how to create a custom signature to monitor audio and video streams would be appreciated.
Eugene

Hi Blayne,
I really appreciate your answers and time you spent. I wish this would be helpful not to me only. I'm still confused by all the intrinsic details of how to make a good custom signature. Is there any good guide? May be TAC has its internal guide on how to troubleshoot and create custom signatures based on regex and content type. I'm looking at the TCP packets of the capture made while watching youtube video and this is what comes from the server:

Audio+Video Issue in AE CS3

I'll start off with the Audio issue first, because i can't even get a signal at all yet.
I searched through some other threads and read some information and tried this:
1. Checked Audio Hardware, has correct soundcard settings.
2. Checked Auido Mapping, has correct settings.
In the top right corner there is a green audio DB meter, but when i import a movie and push play,
the movie will playback with no audio, and no movement in the green audio DB meter.
I pushed LL before playback, and i can see the actual soundwave as the movie plays back,
but still no audio.
The soundcard is a M-audio Firewire Solo, and works great with Adobe audition.
I even used "edit in adobe audition" through AE, and the sound came out fine in audition.
The video problem i am having, is after i installed AE CS3, on the first run it came up
with a message saying CS3 was not compatible with my video card, so it disabled some
setting, (which i could later turn on in preferences?) i don't remember what setting it was talking
about, but i believe it had something to do with OpenGL.
Either way, video playback does work, but when i try to put certain effects over the video,
it seems to run very sluggish.
The video card is a ATI Radeon HD4850.
My system us running XP sp3 with 2x2gb Ram.
thanks.

You have a misconfiguration of your graphics card driver. That card by all means should have enough juice to run with OpenGL. Try a newer one/ different one/ flip a few switches.
Either way, video playback does work, but when i try to put certain effects over the video,
it seems to run very sluggish.
What effects and what source footage? Some effects are just slow and decoding certain footage types can just as well be slow, even more so with no hardware acceleration available. Could be perfectly normal behavior....

Stream audio & video from my MacBook Pro to my HDTV

What components do I need to stream video from my Mac Book Pro to HD TV. I have wireless access throughout my home.

One common way is to use a DNLA server and client. Some TVs are internet-capable and have the ability to receive media streamed on a local network. If not, you will need a device attached to your TV which acts as the DNLA client - such as a PlayStation 3 or Boxee.
You still need server software running on your Mac, though - look into Twonkyserver and TVMobili. Some network drives will also act as a DNLA server, so you can store your media there and not have to keep your Mac open and running.
