Bug: Quicktime 7.1.6 won't play MPA audio streams

Since upgrading to 7.1.6, Quicktime will no longer play RTP streams encoded as Mpeg-1 Layer 2 audio. The stream will run, and the info window will show the bitrate, but no sound is heard. The behavior is now the same as Layer 3 (mp3) streams, which is a much older bug. Any chance for a fix?
Thanks.

Please ignore this post, it looks like I was completely mistaken, it's working now.

Quicktime 7.6.4 won't play h264 encoded videos on my 10.4.11 MacMini

Hello:
This is my first post. I read through the forums and this seems to be the correct place to pose my question. If it's not, my apologizes.
I'm trying to find out why Quicktime 7.6.4 won't play h264-encoded video on my MacMini (G4 PPC). I'm running 10.4.11. I recently installed Perian 1.2.1 and it got some .avi files to play correctly, whereas before there was no sound. But the h264 files still get me a black screen, albeit with sound now. Some h264 files can be played in VLC Media Player (but that's a horrible player compared to Quicktime in my opinion, as it constantly drops frames and eats 100% of my processor time), but VLC even has the black screen problem on some h264 files as well.
I've also tried MPlayer OSX but that's really an alpha-type development and has a lot of bugs. Many movies it can't even open.
Sorry for the rambling, but again my question: Is there any way to play h264-encoded video in Quicktime 7.6.4 on my Mac?
Thanks in advance for your expertise and advice.

Mr Ram,
There is a group of Quicktime specialists in Apple.com ⇒ Support ⇒ Discussions ⇒ Quicktime .
The more data you give us, the easier it is to help us help you to diagnose your problem. Your disk space would be very useful. Contrary to some, I advocate iDefrag to assist VLC and MPlayer, which you were a little hard on.
GNU/Linux's free offerings
MPlayer was developed a decade ago, and I prefer it for viewing DVDs (for 'DVD Player') seems too dark. VLC (legally) copies many CRM-protected DVDs of yours, so you can play only the burned copy. When I'm having a problem playing a DVD, the VLC log tells me all: only perfect DVDs play well on VLC.
There are two ways of viewing everything.
Streaming MPEG-4
+H.264/MPEG-4 AVC+ is a fancy codec based upon MPEG-4: it requires a powerful processor to de-compress it. I watched an MPEG-4 movie from a G3 iBook in 2005. It played flawlessly.
Your Problem
Quicktime 7.X applications can not play +H.264/MPEG-4 AVC+ streams. It was a bug Apple never fixed. Frames are dropped because H.264 is so slow that it requires special hardware. You, I'm sad to say, don't have it.
To quote the Wikipedia on Quicktime: 'QuickTime 7 lacks support for H.264's Sample Aspect Ratio .[67] QuickTime X does not have this limitation; many Apple products (such as iTunes and Apple TV) still use the older QuickTime 7 engine.'
My Quicktime Pro on a PPC PowerBook is 7.6.4. You can either use a Linux transplant or upgrade to Quicktime X. Those more familiar with Macs may have better ideas for you.
My best,
Bruce

Quicktime 10 won't play the audio on my .3G2 files??

How can I alter the set up for Quicktime 10 so that it will play the audio for all of my .3G2 files?

Is there no way to update a codec or something on QT X? Kinda silly to have 2 different versions of the same program to play different video...
All of the standard audio components should already be installed. The question is whether or not they can be accessed under the 32-bit QT operating structure and which specific audio codec is having a problem.

Itunes won't play, store won't play, no audio

itunes won't play, itunes store won't play, no audio.

Make sure the volume slider in iTunes isn't all the way to the left.
If that doesn't work, check out this Apple article -> iTunes and QuickTime for Windows: Audio does not play or plays incorrectly

Movie purchased in iTunes won't play. Audio is fine; video doesn't appear.

Yes there is.
Go to the iTunes Store on your computer. Click the "Purchased" link about halfway down on the far right side. Click the "All" tab on top. The song is there. Re-download it.

Streaming audio from my IPAD to my Apple TV from Rhapsody application. when Apple TV go into Screen Saver mode, about 5 minutes after that it stops playing the Audio Stream and goes into Sleep mode.

I am Streaming audio from my IPAD to my Apple TV from Rhapsody application. when Apple TV go into Screen Saver mode, about 5 minutes after that it stops playing the Audio Stream and goes into Sleep mode. I am using the Optical Out from the Apple TV to my receiver, the Apple TV is hard Wired to the Network, the IPAD is Wirelessly attached to the network (it continues to play the Audio Stream). When the Apple TV is turned back on it resumes playing once I manual select it for output from the IPAD. All device are on current releases of software. I have no Video hooked up to the Apple TV. How do I correct this?

Intermittent problems are often a result of interference. Interference can be caused by other networks in the neighbourhood or from household electrical items.
You can download and install iStumbler (NetStumbler for windows users) to help you see which channels are used by neighbouring networks so that you can avoid them, but iStumbler will not see household items.
Refer to your router manual for instructions on changing your wifi channel or adjusting your multicast rate.
There are other types of problems that can affect networks, but this is by far the most common, hence worth mentioning first. Networks that have inherent issues can be seen to work differently with different versions of the same software. You might also try moving the Apple TV away from other electrical equipment.

C# Webbrowser using VLCplugin to play online audio stream

Hello all,
I have been trying to get the VLC to play a audio stream from a URL address.
I created a forms application and added a webbroswer from the toolbox. I can navigate no problem but if I goto a link like
http://audio.wgbh.org/otherWaysToListen/wcai.m3u
I get a popup dialog that asked do I want to open this file. If i accept VLC opens and it plays no issue.
However, what I want is it to play without the popup and in my application not with the VLC installed on my computer.
I have seem many things about VLC selecting files but I have not been able to find a reference for pulling a stream with my C# form when browsing with the webbrowser item on my form.
Any help would be thankful.

Hi Badidea,
>> However, what I want is it to play without the popup and in my application not with the VLC installed on my computer.
Do you want to open the url without the popup? If so, I think you could block downloads from the webbrowser control, the link below shows the details:
# How to block downloads in .NET WebBrowser control?
http://stackoverflow.com/questions/483262/how-to-block-downloads-in-net-webbrowser-control
But with this way, I am afraid that you could not open the audio. If you want to open the audio without the popup, I think you could automatically download the file, more information you could turn to the link below:
# Suppressing the Save/Open Dialog box in a WebBrowser control
http://stackoverflow.com/questions/3538874/suppressing-the-save-open-dialog-box-in-a-webbrowser-control
But if you want to open the audio in your application without the VLC, I am afraid that you could not achieve that. As you know, the audio needs the special player from the URL, I think it is restricted if you want to open the audio without the player.
Sorry for the inconvenient.
Best Regards,
Edward

Quicktime 7.1.3 won't play .mov or .swf inserted in powerpoint

I have been using Quicktime in ppt for sometime and it always played video loops fine. I upgraded to 7.1.3 and I have all kinds of problems. I have gone under the Quicktime preferences and MIME files and activated video and miscellanous types. Once I close the window though it reverts back to default and I can no longer open mov or swf. Is there a way to save these changes? Secondly when I insert a movie into ppt now it does not work. If I just open the file using Quicktime it works but not when embedded in ppt. I have reinstalled Quicktime 7.0.4 and the movies work fine. The other problem I have is that I upgraded to iTunes 7 and it requires 7.1.3 so when I remove 7.1.3 I can't use any of the video features of iTunes. Does anybody have any work arounds. Very, Very frustrated In South Dakota

Quicktime Kirk,
I have downloaded another persons inquiry because it is exactly the problem I am having. Here is his post
"I make movies of cells and convert them to quick time and insert them into powerpoint for presentations for conferences. I never had a problem with this until I upgraded to office 2004 and now many (but not all) of my movies won't play. They seem to be there but when I click play they go white as though there is only the first image. I had saved them as cinepak and or jpeg A usually with image J or older ones from the original NIH image and I can't figure out what the problem is. I even upgraded to quicktime pro to resave them as self contained but still they don't work when I insert them. I can play them all with quicktime player and when I make new ones now in image j I save them as video and that seems to work but it would be very difficult to go back and do that with everything. Does anyone know why or how to fix this?"
My additional comments would be I used the Sample_iTunes.mov from QT and it plays like a champ in PPT. My movies are all from 2004. When I save them in the QT 7.1.3 it doesn't seem to make any difference. The older movies insert into PPT as a QT icon with 4 color quadriant. Everything including .swf are now working in QT. Thanks for your help. When I go back to 7.0.3 they work but then I can't play my videos in iTunes unless I do an erase and a reinstall to get rid of the updated iTunes. Thanks

Audio won't play after audio render

I have an MP3 on audio track 1 in Premiere/CS4, placed underneath video clips which I've unlinked from the audio and deleted/cleared those unlinked audio files. The MP3 file plays fine until I render the timeline and then it stops playing. If I 'double click' the file (placing it back in the source window) it plays fine there, but won't play in the timeline. I've included the file properties below. Does anyone have any idea why this is happening and what I can do to fix the problem?
Type: MP3 Audio
File Size: 4.2 MB
Source Audio Format: 44100 Hz - compressed - Stereo
Project Audio Format: 44100 Hz - 32 bit floating point - Stereo
Total Duration: 00:03:03:32868
Average Data Rate: 23 KB / second

I could do a MP3 to WAV conversion, but that defeats the
purpose of storing my (growing) music library in MP3 for space conservation.
I understand the space problem. Only do this for files that you are using as Assets, Imported into PrPro, if they give you a problem.
Seems I'm finding I have to do a lot of 'work arounds' with CS4.
Well, it does seem that you are not alone on this one. However, my problem came with PrPro 2.0. In my case, it only happened once, but did affect about a dozen Audio files in several Sequences. Did not realize the magnitude of my issue, and only observed it after a busy day of trying to Keyframe some Effects and doing multiple Renders to check things out. One moment all Audio in that section was playing well - next moment (after one more Render) dead. Others, who replied to my thread indicated that it had happened to them too, in similar circumstances. Trouble was, none of us could duplicate it and some had this happen on their first Render, while I'd probably done a dozen that morning. Have never had it happen again, and finished that Project with hundreds more Renders, just like I'd done, with not one problem. I certainly can not call it a Bug, as there was no way for anyone to reproduce it. Still, whatever allows it to happen, under the right (or wrong) circumstances seems to be around two generations later. Hey, phases of the Moon?
Good luck, and let's hope that neither of us sees this behavior again,

Premier Pro CC won't play / render audio or video after today's update

Foolishly I allowed CC to update my software ( CC 2014.2 ) and now it won't play or render video or audio. It will allow me to scrub through and see the video, but the play button just turns to a square and does nothing.. Trying to render anything does even less.
This behavior can be repeated in both in the source window, as well as the program window when I scrub the timeline.
Premier Pro worked fine yesterday, with the same files. I booted onto a back up drive that had my old CC program cloned... And it still works fine.. I think it's safe to eliminate hardware issues as well as file / file types...
I have deleted the Premier Pro app and reinstalled, I have reset the preferences, I have dumped the media cache.
I have tried to set up new files, both on the internal hard drive, as well as an external... ( both work fine with the old system backup )
Still the same NON results...
Running on an iMac, using OS 10.8.5
Processor 3.5 GHz Intel Core i7
Memory 32 GB 1600 MHz DDR3
Graphics NVIDIA GeForce GTX 780M 4096 MB
Any solutions would be greatly appreciated....

DVD videos won't play, although audio works?

since upgrading to 10.8.4, DVD videos, including rental movies, discussions from teaching sessions, and conversions from home movies won't play, although sound is audible. Video player is "App version 5500.38.2; Framework version 5.7.1. I have rarely used DVDs on the machinge, but did work fine in past. Any suggestions appreciated

What comes to mind is that the DVD player will only work with certain original Apple manufactured DVD drives. (Licensing issue since Apple pays a license fee for the MPEG software on the DVD drive.) Are you using the original built-in drive? VLC doesn't care about the license but states that it is up to the user to insure proper licensing. Look in About This Mac to see what information it has about the DVD drive. Perhaps it is somehow sending the wrong information.
Can you view MPEG movies on the Apple site. For example the movie trailers.

Starting in the middle of an animation won't play the audio

I was creating a frame-by-frame animation in Flash Pro CC that went with an audio file I added to the project, however when I start from the middle, or anywhere besides the start, the audio won't play, but the animation will. I chatted with a customer support guy and he directed me here. Is there any way to fix this?
I'm running Windows 8 64-bit.

if that's an html5 project, no.
otherwise, assign your sound's sync property (in the properties panel) to stream, not event.

Premiere Pro and Soundbooth won't play video/audio for more than a second.

Ok, so my issue is that Soundbooth won't play audio for more than a second. It plays a quick bit then stops. Premiere Pro also does the same with video, it plays a quick bit then stops. I don't know if it is connected or not but when I try to change the audio output in Soundbooth to System Default I get this error:
I set the permissions to premiere and soundbooth to full but it didn't work. I've tried UnInstalling and ReInstalling but that didn't fix the issues either. All of the other programs seem to work. Any help would be much appreciated!!

Here is the fix.
1. Open Finder and navigate to /YOUR_HD/Library/Preferences
2. Rename or move to the Trash the file: com.apple.audio.AggregateDevices.plist
3. Relaunch The Program

Windows media won't play mp4, audio no video

I upgraded from a desktop to the HP TouchSmart 15 TS Notebook PC so that I would have all the functionality
of a new operating system that would work. Guess I was mistaken?!?!?! I have the same problem I had with my old crappy desk-top, MP4 videos still don't play on Windows 8.1???? I get audio but no video????? just a black screen?????

According to Microsoft support website, Windows Media Player still won't support MP4 files. Though we can make WMP play MP4 video by install some codec, sometime we still encounter can't play MP4 in Windows Media Player issue. MP4 is a container format which may contain multiple video and audio streams. And the video and audio stream can be encoded any of several ways. If the MP4 video or audio codec is not WMP installed codec supported one, Windows Media Player won't play MP4 video of this kind. In order to solve "Windows Media Player won't play MP4 files even when the appropriate codec is installed" and to successfully play any MP4 video in Windows Media Player, we had better convert MP4 to Windows Media Player more supported video format like WMV, AVI.
