Why won't Firefox play live video streams such as webcam pages.

just upgraded to windows 7 as well as the latest version of firefox. Flash movie sites such as youtube play without difficulty. It is only sites such as http://www.liveduvalstreet.com/crowdcam.htm that do not work. before these sites worked without difficulty.

Thanks for the response. That did indeed solve the problem. Figured it out about an hour after posting. Interestingly it works fine on my wifes computer (vista64) without the wmp plug in.

How to play live Video Stream with Flex?

I'm trying to get Flex Builder 3 to play a live video stream with Flash Media
Server and Flash Live Media Encoder.
I'm able to stream pre-recrorded (vod) flvs in flex from flash media server.
I'm able to stream live video using Flash/FMS/Flas Live Media Encoder, but not
with Flex.
This code streams pre-recorded Video on Demand flvs, but not live streams:
If I change source to "rtmp://localhost/live/livesream.flv, I get nothing.
What am I doing wrong?
<?xml version="1.0"?>

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">

Oh and sorry for the double post. I didn't know there was a seperate FMS forum.

That worked! Thanks *very* much. Stupid of me to forget to set the live attribute to true. Also removed the .flv. BTW: what video component do you prefer?
Here's the working code:

Why won't Firefox play mp4 from my website using xplornet satellite?

I can play mp4's on my website using Firefox and dial in. When I try and use xplornet sattellite it doesn't see them .It will open wmv. If I use Explorer and teh satellite I can play them. Many people with different operating systems and browsers can play them.
What do I have to add, change or do for Firefox to play mp4 from my website? We have loaded the latest Firefox and it still doesn't work. It ha sto do with the satellite and Firefox. We must be missing some plug in, add on or something else.
thank You

Hello,
I think the problem is your OS. Firefox supports playback of H264 encoded video (mp4) but only where the ability to decode the stream is already included in the Operating System or in the hardware.
This means that it will work for Windows Vista and above but not for XP since XP doesn't include the decoder.
''"To avoid patent issues, support for MPEG 4, H.264, MP3 and AAC is not built directly into Firefox. Instead it relies on support from the OS or hardware. Firefox supports these formats on the following platforms: Platform Firefox version Windows 7+ 21.0 Windows Vista 22.0 Android 20.0 Firefox OS 15.0"''
See here for more:
* https://developer.mozilla.org/en-US/docs/HTML/Supported_media_formats
* https://bugzilla.mozilla.org/show_bug.cgi?id=799318
I am not sure but it may work if you install the VLC plugin: https://wiki.videolan.org/Windows/#VLC_Plugin_for_Firefox_.28Mozilla.29
If you have control over the site then I suggest using a different Video format which is not patent encumbered. The webm format is one option:

I hope this helps.

Why won't ATV play HD video from iMovie?

This question incorporates two different systems (ATV and Imovie) but I thought I would start here.
ATV will play HD movies rented through Itunes. Why then can I not Save/Export movies from Imovie in HD and view them on ATV?
Any thoughts?
Thanks,
Ehren

You can export HD movies from these applications for the Apple TV, it's just that they need to be in a specific format. Rudegar has provided those specifics and I proposed options that are available in both iMovie and Final cut that can meet them, the export settings will produce the same specification of file that you can purchase from the iTunes store.
If you are asking why the Apple TV doesn't support all the types of files iMovie and final cut can produce then there are a few reasons for that:
Firstly the Apple TV has limited capabilities, it simply can't play the high end sort of stuff these editing applications can produce, to do that it would need much more processing power which would ultimately make the Apple TV more expensive and out of reach for the vast majority of its target base who simply want iTunes store quality content.
Secondly, the editing software can produce content for many delivery platforms, iMovie and final cut are targeted at a much wider consumer than just people wanting to make video for the Apple TV, some want video on DVD, others on blu-ray, others may want to export it for windows users or just play it on their macs.
Finally, not all export options are delivery formats, there are times when you want video in non delivery formats for further production, production formats are not designed to be used for delivery and in many cases simply aren't playable on any (consumer system).
It's the job of the editor (in these type of applications) to make sure they are delivering the finished movie in the right format for what it will be used for. In the case of the Apple TV, that's share to iTunes and then choose the Apple TV option.

Why Won't QuickTime Play Video?

Hi,
I use a Power Mac G4; run Mac OS X 10.4.11 Tiger; QuickTime 7.6.4. Why won't QT play the following video:
www.globalwebsupply.com/images/mdsmarttool.asx ?
Angel

I use a Power Mac G4; run Mac OS X 10.4.11 Tiger; QuickTime 7.6.4. Why won't QT play the following video:
www.globalwebsupply.com/images/mdsmarttool.asx ?
1) The Advanced Stream Redirector (ASX) format is not supported by QT X.
2) The Advanced Stream Redirector (ASX) format is not supported by QT 7 without third-party support such as the Fil4Mac WMV components.
3) Even the Flip4Mac WMV component only "supports a small subset of the ASX file format."
On my system:
1) Trying to play the file directly in QT X using the "Open Location..." option returns the fillowing message, "The movie 'mdsmarttool.asx' can’t be opened because the file is not in a format that QuickTime Player understands. The file may be damaged or may not be a movie file that is compatible with QuickTime Player."
2) Trying to play the file directly in QT 7 using the "Open URL..." option returns the following message in the "Inspector" window, "Movie Unavailable."
3) Trying to download the linked file does nothing. (Aborts action without any message.)
4) Trying to open the URL in Safari returns the following message, "The operation couldn't be completed. A Microsof Media Server (MMS) error was encountered. (-19160) Try again. If the problem persists, contact the website administrator."
Based on these results, it would appear that there may either be an access problem or a file type support problem.

Why can't I play any videos on Firefox Mobile?

Why can't I play any videos on Firefox Mobile? I know that currently Firefox Mobile does not support Flash, but mp4 videos will not play either.

I fixed it by rebooting, now everything works. Thanks Demo, for your help.

My mac won't read my external harddrive's videos that I took with my Nikon. Half the videos won't play, and those are .avi files. WHY won't they play anymore and how can i retrieve them?

My mac won't read my external harddrive's videos that I took with my Nikon. Half the videos won't play, and those are .avi files. WHY won't they play anymore and how can i retrieve them?

What exactly is your problem? Is it, (a) your Mac doesn't read your external disk, or, (b) you can't retrieve your videos, or, (c) you can't play them, or, (d) you were able to play them at one point, but not any more.
What version of Mac OS X are you using, what app are you trying to play your videos with, what happens when you do, and what error messages, if any, do you get?

Why won't FireFox 4 play mp3 files that have been created since the FF update? It will play mp3 files created prior to the FF update. All of the mp3 files have been created in the same manner, as bounces from Logic Pro 9. Thank you.

Hi David,
Thank you for your detailed question. It sounds like the real issue is pdf files. Are there any antivirus/firewalls that might be blocking this specific file type? or are there any preferences in your control panel that might be blocking this?
Do you have any stored preferences for PDF files in Firefox?

Live video stream play permission on server-side

I have a live video stream application one-to-many for
example, and i want to send video only to few clients, not to all.
Like:
quote:
application.onConnect = function(client, canSeeVideo) {
// canSeeVideo = boolean
this.acceptConnection(client);
if (!canSeeVideo) client.receiveVideo(false);
// and after this, can be swich to TRUE or FALSE ?
client.receiveVideo(true);
I only want to do restriction for Video, from server-side
with FMS, or if can't be possible.. how can i put for example a
black screen on video ? :) and after can be removed, etc...

1.
necesary client.receiveVideo() and client.receiveAudio()
server-side functions
Thank you fmslove for you trying to help me but
client.readAccess property can NOT be set after client
connection was accepted, and for me is useless. Any other
solution(s) ? i strong recomend to Adobe FMS dev staff to implement
this feature because is refering to security client-side solution
from server-side. I have bad experience with users trying to modify
the Flash Player (plug-in) run memory and set values for my swf
without my accept, and is nothing that i can do from client-side
like NetSream.receiveVideo(false) on many-to-many or one-to-many
live A/V stream.
2.
a necesary server-side video encoder solution better than
Sorenson Spark
If in future FMS staff from Adobe will implement this
necesary security feature on server-side like a copy of
NetSream.receiveVideo() function from client-side, i will be happy
if i see a solution to encode LIVE video stream on server-side
because
Sorenson Spark video encoder built-in Flash Player (plug-in) is
very old and unuseful.
If this can't be possible i hope the future Flash Player
version (10) will have a better video encoder built-in than
Sorenson Spark !!!

Switching video source for live video streaming

Is it possible to switch the video source from a video
capture card to a standalone video during live video streaming? We
are streaming live TV and we want to skip playing any
advertisements.
If this is not possible, what is the best way skip playing
any advertisements? Do we have to do it at the client player level
i.e. catch an event from the video player and play a predefined
video when the live video stream is stopped?

Thanks for reporting your fix. That news could be very important to those who delete events from their hard drive to save space, but may want to reload them later to do some editing.
It sounds like the key is re-importing with exactly the same name as before.
Just curious: What kind of camcorder? Was it MiniDV tape? Flash? Hard drive? DVD?
It strikes me that with tape it might be difficult to reimport an exact match. If you start on a different frame, the pointers could be off. But if that is not the case, it is very good news.

JDunlop,
thanks for your quick reply to my java.sun.com forum posting! i just got back from vacation, so i didn't get a chance to try your method til now. i pulled your email address off the website to update you on my problem playing an avi file in JMStudio (JMF).
as per your instructions, i downloaded the divx player at www.divx.com and tried to play the avi file. this is the error the divx player gives:
Divx Player 2.1
The file contains unknown video data
The file contains the following type of data:
Video data: FOURCC code "MP42"
You may need to install a new video codec on your computer to watch this video
Some quick questions:
1. Where could I find the "MP42" codec to play my avi file in JMStudio (JMF)? Does java.sun.com have video codecs?
2. You mentioned in your posting "If you don't have the one that was used in the encoding, your out of luck." Does this mean that I need to know how the avi file was originally coded and have the original codec to decode (play) it?
Thanks,
lac410
P.S. If you need more Duke Dollars for your help, I'd be happy to award them to you.

Author: JDunlop Jun 5, 2003 5:00 AM
sounds to me like you are missing a video codecs. If you don't have the one that was used in the encoding, your out of luck. Download the player from divx.com, it will tell you which codecs the video needs (if it won't play). You can then search the net for that particular codecs.

Live video stream keeps replaying parts of stream.

While watching live video stream the video jumps back and replays what has already played. It doesn't skip forward only replays, no problems with chopping stream or anything else. Thanks for your help.

Dear RahiSC.
We actualy never found the solution to this problem. This issue was only there when we were using BlackMagic Studio cards using SDI link. Now we use Osprey video capture card using composite input and now everything works perfectly.
After that we didn't yet try to resolve the issue when using BlackMagic Studio cards using SDI link.
best regards,
Borut.

Live video streaming not working

My live video streaming is not work properly. I can watch video for a few seconds to a few minutes before it stops. Why??? What can be done to fix this?

I downloaded a new version of the app NDTV , but the problem still persists .
I am using iPhone 5 .
Please advise, if there are any specific updates you are pointing to . Because I dont have any pending updates showing in App store

AAC audio causes stuttering in live video stream playback

I am using the Spark VideoDisplay component and setting the mx_internal bufferTime to 0. (videoDisplay.mx_internal::videoPlayer.bufferTime = 0) I am doing this because I need to have the absolute minimum delay in the live video stream. I am broadcasting video files as a live stream using ffmpeg, through Red5, then to the client. ffmpeg is not re-encoding the video or audio. I am using h.264 video format. I have tried encoding videos using Adobe Media Encoder and ffmpeg.
When I have a video stream only and no audio stream this works fine, but when I have an AAC audio channel with the video, I frequently see the video jitter badly. It looks like the video is quickly going forward and back a few frames. When this problem occurs it will go on for some time and sometimes eventualy starts playing normal. When the video is playing normally the audio sounds fine. When I play the videos in a regular media player (like VLC) they play and sound fine. Also if I use an mp3 audio channel I don't see the jittering
Does anyone have any idea what the cause of this problem might be or how it can be resolved?

Ah, yes, I am not serving high-def video myself. H264 is probably better, but my understanding is that you need hardware acceleration to get good performance from it (again, not an expert on the topic, that's just what my understanding has been...)
This document [pdf] may have some usefull info on choosing an optimal encoding for your needs.

HT3775 why won't quicktime play .mp4?

why won't quicktime play .mp4? I just downloaded a 1.2 gig mp4 video that won't play.

Thanks. I just found it strange that it was one of many files that I ripped from a DVD ( part of a box set of a TV series, and all the others were fine so far. Funny that this one in particular was causing a problem.
