Leopard 10.5.2: BREAKS video streaming!

Hi All,
Anyone else had this issue?
Prior to 10.5.2 (at 10.5.1) I was able to stream videos from my G5 to my Macbook Pro without a problem. Now I can't stream at all. It works for the first 20-30 seconds, and then dies. I need to force quit quicktime.
Apple needs to fix this FAST!
By the way, my router is the 802.11n Airport Extreme.

Same problem here since updating to 10.5.2. Can't Apple release an update that doesn't break something. Streaming via Front Row from my MacMini to my MB Pro is messed up. It worked beautifully under 10.5.1, but under 10.5.2 there is tons of buffering delays (30 secs or more).
I've got a Linksys WRT54G v. 3 router with the latest Tomato firmware.

Ios 6.1.2 breaks video streaming again on ios devices

I am a subscriber to a LIVE TV streaming here in Singapore. ios 6 broke the streaming joy on wifi
Waited for a new ios patch and 6.1 fixes that. Now 6.1.2 broke it again... WHY APPLE WHY?
TV programmes are streamed LIVE and only available via mobile safari.

You can not revert to an earlier IOS. Besides, your issue is extremely rare.
First, try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. It could take well over an hour! Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod. As before, say "yes." Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time. If that happens, only the apps that are part of the IOS will appear on your device. Corrective action is simple - choose manual "Sync" from the bottom right of iTunes.
If you're unable to do the Restore, go into Recovery Mode per the instructions here.

.Mov files in CC : The File Has no Audio or Video Streams

I recently updated premier to CC , since i have issues iimporting any .mov files at all.
The specific ones Im trying for my current project are exports from AE , rendered lossless animation .mov , worked fine in CS6 , will play in quicktime and other generic's but always getting the The FIle Has no Audio or Video Streams message when trying to import into a project.
Quicktime is updated so I can't understand why the won't play, is this a CC bug ?
i go back to cs6 on my other comp they open fine...
Ive seen a few topics on this none with a resolution and most of those where from cam's, this is an export from AE, anyone able to help this is stopping me from working atm ......

I can verify that Apple screen recordings without audio do not import into any Adobe premeier.
Details on screen recording from Gspot v2.70a:
H.264
qt : Apple QuickTime (.MOV/QT)
File Type: QuickTime (.MOV)
Mime Type: video/quicktime
Len: 1:03.083
Frms: 1,521
Qf: 0.153
Frames/s: 20.000
wx: 1280 x 800
sar: 1.600 (8:5)
However Apple (MAC OSX) screen recordings WITH audio will import.
I would think this should be fixable with hotfixes...
If you (adobe staff) have access to macbook pros 2012 or 2013 models, open quick time pro, do a screen recording, make sure no audio is recording, just your screen movements.. then export to 1080p video (mov is only option).. then on a windows PC try to import that file into adobe premiere. The file will play perfectly fine natively in windows with any player so long as a H264 decoder is available on that system... the problem here is Adobe Premiere. Not the users system.
Edit:
To help those with this issue.. just make sure when you render your mov that you have ANY kind of audio in it.. and just remove the audio track once imported into premiere. I know it's frustrating and you would think something as simple as not having an audio track wouldn't break premiere but alas... we have to work around the shortcomings until they decide to fix it.. just like the VFR issue in premiere.

Video streaming mixing

Hello!
I want have a live broadcast (like web TV) using Flash Media
Server. I taking video right from digital camera. My question is
how i can put over this video stream some image (channel logo) or
another video stream (for example breaking news line on the
bottom)? What i need for this?
Thanks

If you plan to game or do video editing stay away from HP, none of their video cards are up to the task and they will all run too hot.

NVIDIA GT 560 graphics card can handle most anything that's out there (for now). Notice how thick it is for improved air flow, if I remember correctly it has to cooling fans to get the job done.

Slow video streaming speed

I've recently run into some problems streaming videos online. No matter which sites I visit the loading time is extremely slow. Everything else still works fine, it's just when i try to stream videos that it seems to slow down. I've tried using different internet connections (at home, school, friends) and still had the same problem while other computers using the same connection had no problems at all. I've tried disabling the firewall, emptying the caches, checking quicktime settings, reinstalling video codecs (divx, flip4mac, perian etc) nothing seems to work. Videos stream at 1kb/s but I can download the same video to my hard drive at 300+kb/s. If anyone can help me with this I'd greatly appreciate it.

I've had the same problem more or less since I've owned this MacBook (@ 18 months). It's a 2.2Ghz Intel Core 2 Duo with 2GB of RAM. I've tried all sorts - keeping my Dock items to a minimum,I have a plain Desktop Wallpaper with only 4 Desktop Icons, regularly flush all caches, and (because of the horrendous noise), have done the "Reset" thing on more occasions than I care to remember. I've also kept all video players up to date. Snow Leopard has further exacerbated the problem. Nothing has so far worked for me.
Although I had Apple Care for the first 12 months, I didn't think I needed it any longer so I let it lapse, although I still pay for MobileMe. Since experiencing the "Case Cracking" phenomena, I've tried contacting Apple without success, and I really don't see why I should traipse over 140 miles and pay for a Genius consultation to get the case issue resolved.
The video slowdown is just the tin hat on everything for me. What I have here is an almost unusable piece of cracked junk (almost forgot the keys are also coming away!) that cost me well over a grand. Can you imagine what I said to my wife when I learned she was planning on buying me an iMac (she has the MacBook Pro - which in fairness, isn't plagued with problems)? I've got enough Apple stuff to fill a small suitcase (iPhones, iPods, computers, peripherals), but I won't be buying any more. A sub 500 quid machine running any MS OS or Linux has got to be miles better than this. Good luck in your quest.

CS-Bytes sizes increases to double on play/pause video stream

Hi ,
I am working on audio-video chat web application. when 3-4 or more user publishing and receiving video stream the stream starts breaking.
When I read the FMS log then cs-bytes per second of FMS server were in megabytes and not same as the maxBytesPerSecond send by client machine.
Then I think this is the reason for Audio breaks.
Anybody having any solutions to remove or reduce theses audio breaks then please reply this post.
Thanks.

You DO realize that Firefox has released FOUR new versions since the one you're using, right?

Downloaded firefox 5.0.1. video streaming fails. get the wheel of death

I downloaded firefox 5.0.1 and now the video stream fails, devolving into the wheel of death

Jerky Video Streaming

Since upgrading to Leopard I've moved all my video files (movies) to an external hard drive connected to a Mac Mini. Most are ripped movies from DVDs. With Leopard file sharing I can wirelessly access the hard drive connected to the Mini from my iBook and watch a movie on my iBook with DVD Player. It actually streams pretty well (better than I thought) but does have frequent and annoying stuttering of the video stream. I was wondering if there are any system settings I could tweak to minimize the jerky playback.

Use the following as a guideline for streaming video over a wireless network:
o For 4801i SDTV Quality Video: 2 to 5 Mbps (802.11b/a/g/n)
o For 480p DVD Quality Video: 6 to 8 Mbps (802.11a/g/n)
o 720p/1080i HDTV Quality Video: 18 Mpbs+ (802.11a/g/n)
o 1080p HDTV Quality Video: 20 Mbps+ (802.11n)
So, if you're getting the full bandwidth (54 Mbps) with your AirPort Express Base Station (AX), you should get relatively good performance streaming everything up to 720p/1080i HDTV media. Beyond that would be iffy. The problem is that it is highly unlikely that you are getting 54 Mbps due to either free space loss or some form of Wi-Fi interference. Typically, your 802.11g wireless network would realistically get around 15-20 Mbps on average.
It is very possible that you may have some form of Wi-Fi interference in the immediate area that is preventing your AX from getting a good clean signal.
I suggest you perform a simple site survey, using utilities like MacStumbler or iStumbler to determine potential areas of interference, and then, try to either eliminate or significantly reduce them where possible. This should result in better video (& audio) streaming performance.

Internet video streaming on G5 laggy, choppy

I have a G5 Mac Pro. Latest OSX one can put on it. Currently hooked up via DVI to HDMI to 46" LCD TV. Largely, everything works great. All sound and video and software works fine. The one problem I have run into which could be a deal breaker is that video streaming from the web is terrible. It is laggy, choppy, slow, etc. Sometimes the sound is off. The install is pretty fresh. I haven't checked to see what media apps might be installed, for example Flip4Mac. I have hunted around and heard things like Flash, Silverlight, or just that PPC processors cannot handle video streaming from the Internet. The video card seems standard and DVD and local video files play fine. All updates are installed. It is also like this when using a regular Dell LCD using DVI. Any suggestions?

Choppy video streaming from samba on wireless network

Hey all,
I have a macbook pro with leopard 10.5.7 installed. The server setup is a Linux server running samba which is wired to a wireless router. I connect my macbook pro wirelessly to the router. Everything is all set up; my computer can connect to the server and browse the files without a problem. However, when I try to watch videos stored on my server through samba, the video is extremely choppy and practically unwatchable. I know this is a wireless problem with my macbook pro because my windows desktop has no problems at all watching videos over the wireless connection and when I wire the laptop directly to the router, the video streams just fine i.e, no choppiness. I have browsed the fourms and the internet but no solution has come up yet. I was hoping someone here might have a solution.
Thanks,
schne1derman

Thank God! I thought I was the only one having this problem.
I also have a Ubuntu box with all my movies and I stream videos wirelessly from it to my macbook using XBMC (ubuntu) and Plex (mac). At first I thought the problem was the wireless G speeds from my previous router so I bought an Airport Extreme Base Station and connected it via ethernet to my existing ADSL/Wireless router on a bridge configuration. Both ubuntu and macbook are now connected at 300Mbps but I'm still experiencing occasional choppy video. The wireless connection stays up at all times so it's not a wireless connectivity issue.
I tried NFS but the problem persisted. I also installed Windows 7 RC on my bootcamp partition and had the exact same problem. Which means it can be an issue with the Airport on the macbook. I don't have another computer with Windows so I cannot say if it would work better on a PC.
At first I suspected the problem was with ubuntu so I posted this on the ubuntu forums: http://ubuntuforums.org/showthread.php?p=7324538
As you can see on the description I was getting those messages on the mac logs:
26/05/09 6:02:19 PM KernelEventAgent[198] tid 00000000 type 'smbfs', mounted on '/Volumes/MediaCenter', from '//ed@ed-linux/MediaCenter', not responding
26/05/09 6:02:19 PM KernelEventAgent[198] tid 00000000 found 1 filesystem(s) with problem(s)
26/05/09 6:02:19 PM loginwindow[197] 1 server now unresponsive
At first I thought it was a problem with the arp tables on the mac. I created a static entry for my ubuntu box. Now the connection is better and the samba volume doesn't disconnect as often and when it does, it reconnects after a while. Before the arp table static entry I had to reconnect manually:
26/05/09 6:02:32 PM kernel smbiodreconnect: Reconnected to ed-linux
One other thing to add. Before installing 10.5.7 (i.e running 10.5.6), I had this problem and the video used to get frozen (samba share disconnection) once or twice on a 1 hour video and reconnected 15 to 20 seconds right after it. Not a big deal. Now it happens several times (5 or 6 times on a 30 minute video) and it takes around 30 to 40 seconds to reconnect.

No video stream when calling 3rd party endpoint from Jabber client

I use my own H323 client based on the H323Plus open source. It works very well with VCS and all endpoints we tried (a dozen or so from every vendor). We have a problem with Jabber Video though, across all versions from MOVI to 4.4.3. When my own client calls Jabber everything works as it should. However, when Jabber calls my client then (1) it takes up to a minute for Jabber to display incoming video and (2) Jabber does not create outgoing video stream. This behavior is 100% reproducible across all PCs we tried. Jabber is registered with either VCS Starter Pack or VCS Control, sofwtare version 6.1 in both cases. We do not use provisioning at this time.
In Jabber logs there is a unclear hint about insufficient resources (bandwidth?) for the video stream. VCS configuration is fine (it works with all other clients like e20) and I do not see anything useful in VCS logs.
To narrow the discussion, this is NOT a firewall, client camera or driver, OS misconfiguration or any other external issue. It is Jabber video having problem negotiating capabilities and/or resources but only it initiates the call. Where should I look for a solution?

I was afraid this will end this way. I hoped you might have had such a case solved already :-).
Audio works fine, no problem at all. The video packets are not sent from my client to Jabber while in the 1 minute wait; the stream from Jabber is not even started. I still think I need Wireshark to decode H225 traffic. Good idea with the interworking log - I was too lazy to go the OS layer. As you surely know, only 2 of the VCS logs are available from the Web interface.
thanks for your help!

Can I see video stream from a website on my tv from my desktop with apple tv

I am trying to watch a weekly video stream from a website using my Mac desktop on my tv with Apple Tv..can I do this?

If your computer is a Mac and new enough (2011+) then maybe. See required specs here:

If you have an older Mac or Windows machine try airparrot.

HT3819 video stream from amazon prime to my TV

i want to video stream from amazon prime to my TV via my ipad, mac book using my apple TV device..

there is no reason to get rid of Apple devices, not when a Chromecast, Roku, or FireTV can be acquired so cheaply.
This is a true statement, but this is a bad option in the long term since your content will be split between different sources, DRM rules, apps, access options, etc. You are going to constantly be running into issues were you want to watch a show that is not available on the device (phone, tablet, etc) you are on. I share "Disgusted_with_apple" frustrations in that Apple has not updated in three years now leaving Amazon FireTV and others with better interfaces and features but having my content locked into Apple's DRM.
Apple was really first to market with a viable TV interface device, and has completely turned the market over to its competitors just by not showing up. And now ATV can not play content, or provide features that ALL of the competitors have. I recently bought an Amazon FireTV and love it. The only advantage Apple has left is the iTunes Store still has more content, but that is not likely to last.

SpryTabbedPanel: Flash player in tabs do not play video streams

Note: I am a complete noob (no experience with Javascript and rudimentary experience with htlm/css). Please be patient (I hope that this is the correct forum for this) and know that I am appreciative of any help or solution that anyone can provide.
Using Dreamweaver CS4 on Mac OS 10.5.8
We recently switched all of our streaming servers from Windows Media (good riddance) to Flash Media Server 3.5 (now getting awesome H.264 quality in comparison).
I was asked to re-design this webpage with the aim of re-organizing the content so that it is more accessible:
http://www.librarymedia.net/VideoGallery.html
We used Adobe's test page for our first page:
http://www.librarymedia.net/flash/videoplayer.html?source=rtmp://63.116.232.4/live/livestr eam&type=live&idx=10
This was meant as a temporary page to get us started, and as you can see, it needs work but at least it works.
I've been working the the final version of this page. My boss wants a tabbed web page with links to our video streams (tab for each category of streams).
This is what I have so far:
http://www.librarymedia.net/Flash2/videoplayer2.html?source=rtmp://63.116.232.4/live/lives tream&type=live&idx=10
I realize that I had several options before building this. One, I could have made a separate page for each tab and linked them with a tab menu. In hindsight, this might have been a better option since I could have just copied the working page that we already have for each tab. Or I could have done what I have tried to do: to use Dreamweaver's SpryTabbedPanel to make the tabs and insert a Flash player with links into each tab.
The problem:
1. The streams do not play. The player says "initializing" and then "please enter a stream name and play". Please note that I used SpryURLutils to get each link to open in the appropriate tab.
2. After reading about the benefits of external vs. inline javascript, I took all of the inline javascript that was contained in Adobe's sample page and placed it in an external file. I tried placing the javascript back into the source code (inline), but this did not fix the problem. I guess there is a Javascript problem or I need extra Javascript code to get this to work. The javascript code is below. Use view source in your web browser to see source code. Please let me know if I need to provide more information.
Thanks.

Should I have posted this in the Spry forum instead? My apologies if this is the wrong forum.
>There is a sample application of the code included with the zip file which shows how to implement it.
The sample doesn't really tell me what I need to do to the code to make it work (I do not know javascript), and unfortunately, I have not found any helpful instructions/documentation online. You've given me the answer, I just don't know enough to implement it. This is what I've done:
1. Placed the FAVideo.js file in my site folder and linked it to the page: <script src="FAVideo.js" type="text/javascript"></script>
2. I added the following code (taken from the SimpleDemo.html example inside the FAVideo folder). My comments in bold. Page at
http://www.librarymedia.net/Flash2/videoplayer2.html?source=rtmp://63.116.232.6/vod/mp4:Ol ympics2010_640x480.mov
         <! To the <body> section:-->
<body onLoad="">
    <div id="divOne"></div>
<!-Do I have to place the entire page within the "divOne" div (or just the section containing the tabs) in order for the javascript to work?-->
         <!-In the <head> section: -->
   <script type="text/javascript">
        playerOne = new FAVideo("divOne", "TabbedPanels1", "demo_video.flv",0,0,{ autoLoad:true, autoPlay:true });
    </script>
<!- I noticed that the body code added a div id called "divOne", so I added the "TabbedPanels1" div id to the above code thinking that this would apply the javascript code to all of the tabs. Dreamweaver adds <div id="TabbedPanels1" class="TabbedPanels"> to the page when you insert the tabbed menu, so I'm thinking the javascript has to point to either one of those for it to work. The "demo_video.flv",0,0 code is probably unneccesary, right? As you can see, I'm completely clueless. -->
    <script>
        playerOne.addEventListener("playheadUpdate",this,myHandler);
        playerOne.removeEventListener("playheadUpdate",this,myHandler);
        function myHandler() {
            //alert("eh");
    </script>
</body>
Once again, thanks for your help.

CTD bug in simple video streaming applet.

I'm trying to write a simple applet to use JMF to allow an end-user to view a video stream that's being served up by VLC. It doesn't have to look immensely pretty (in fact, streamlined is what I want most). I swiped some code from the jicyshout project (http://jicyshout.sourceforge.net) which handles streaming MP3s, and borrowed a framework for an applet from one of Sun's example applets for the JMF.
Here's my code so far:
** begin file SimpleVideoDataSource.java **

* jicyshout (jicyshout.sourcefourge.net), which was written by Chris Adamson.
* The code was simplified (no need for mp3 metadata here), cleaned up, then
* extended for our puposes.
* This is a DataSource using a SeekableStream suitable for
* streaming video using the default parser supplied by JMF.
public class SimpleVideoDataSource extends PullDataSource {
protected MediaLocator myML;
protected SeekableInputStream[] seekStreams;

// Constructor (trivial).

public void connect () throws IOException {
try {
URL url = myML.getURL();
urlConnection = url.openConnection();
// Make the stream seekable, so that the JMF parser can try to parse it (instead
// of throwing up).
InputStream videoStream = urlConnection.getInputStream();
seekStreams = new SeekableInputStream[1];
seekStreams[0] = new SeekableInputStream(videoStream);
} catch (MalformedURLException murle) {
throw new IOException ("Malformed URL: " + murle.getMessage());

Now, I'm still new to the JMF, so this might be obvious to some of you... but it's exploding on me, and crashing to desktop (both in IE and Firefox) with some very fun errors:
# An unexpected error has been detected by HotSpot Virtual Machine:

siginfo: ExceptionCode=0xc0000005, writing address 0x034e6360
(plenty more here, I can post the rest if necessary)
The problem seems to be coming from the "return seekStreams" statement in the first file; when I have execution aborted before that (with a fatalError call), it doesn't crash.
Any tips/hints/suggestions?

You should write your own Applet, where you can easily get the visual component (getVisualComponent())and show it directly in your Applet (you call it "embedded"). As far as I know, all examples (AVReceive* etc.) use the component which opens a new window.
