MPGE-S Payback component for Mac shows video but no audio

I downloaded this software to be able to see and hear videos recorder with a Sony camera that uses MPEG-2. I can see the video now on my Mac but I cannot hear anything.

The QT MPEG-2 Playback Component is a video codec. QT does not natively support either "muxed" AC3 or PCM audio. You have numerous options here:
1) You can use MPEG Streamclip, VLC, or similar third-party media player which does support "muxed" AC3 audio.
2) You can use MPEG Streamclip to demux the "muxed" MPEG2/AC3 content to elementary MPEG-2 video paired with a separate resourced Linear PCM audio file.
3) You can use MPEG Streamclip to convert the "muxed" AC3 audio to "muxed" MP2 audio which is natively supported by the QT player using the QT MPEG-2 Playback Component.
4) You can use iMovie '08/'09/'11 to improt your MPEG-2 video which converts the MPEG-2 video to all I-frame MPEG-2 video with Linear PCM audio which is then compatible with any platforma having iMovie '08/'09/'11 installed.
5) Depending you your system and configuration, you can add AC3 audio support.
Of the available options, I would normally recommed installing MPEG Streamclip and using one of its available options to make the files playback compatible with your system since the MPEG-2 video is left unchanged and the demuxing/re-muxing audio options are relatively fast.

FLVPlayback - Video but no Audio

I'm building a flash projector who's main purpose is to play video.
Everything was working great, but occaisionally the video player showed video but no audio. It did this inconsistently - sometimes it would work, sometimes it didn't, and the volume always reported back as "1"
Here is some of the excerpted as3 I've written:
flv_player.height = 720;
flv_player.width = 1280;
flv_player.x = 0;
flv_player.y = 0;
flv_player.fullScreenTakeOver = false;
flv_player.source = my_source; // (variable string containing path to f4v file)
addChild(flv_player);
// ======= //
flv_player.play();
flv_player.seek(desired_s); // number
for now, I've fixed the problem by throwing in a half second wait using setInterval, after adding the child and starting the player (where // ===== // appears above
What bothers me about this fix is:
A) there's a half second of sitting on black and
B) I don't know why it's not working or why a wait fixes it.
I tried waiting to play until the fl.video.VideoEvent.READY event fired from the the FLVPlayback object, but no dice.
Any ideas out there?

I did come up with a solution, and it seems to work, though it's not as elegant as I'd like. I now add the FLVPlayback component (set to auto start playing), and set an interval to check if it's started playing every 33 ms (or roughly every frame). Once it/s 200ms in, I presume the video and audio are muxed and I can seek. Here's some excerpted code from my MovieClip class:
//adding flvplayback
                              flv_player.height = 720;
                              flv_player.width = 1280;
                              flv_player.x = 0;
                              flv_player.y = 0;
                              flv_player.fullScreenTakeOver = false;
                              flv_player.source = my_source;
                              flv_player.addEventListener(VideoEvent.COMPLETE, on_complete);
                              addChild(flv_player);
                              // right now, it's going to check to see if the video is playing.
                              my_interval = setInterval(start_playing,33);
private function start_playing():void
                              // if the video is 200ms in, we'll presume the audio is muxed and will start the show!
                              if (flv_player.playheadTime > 0.2) {
                                        clearInterval(my_interval);
                                        my_interval = new uint();
                                        flv_player.seek(my_in_point);

[svn:fx-trunk] 12025: Switching out the old video component for the new video component that uses OSMF .

Revision: 12025
Revision: 12025
Author:   [email protected]
Date:     2009-11-19 17:48:04 -0800 (Thu, 19 Nov 2009)
Log Message:
Switching out the old video component for the new video component that uses OSMF. Also fixing RSL issue with OSMF because a change in flex-config.xml accidentally got overwritten. Also fixing a bug caught during the last code review where you would set the volume on the VideoPlayer, but the volumeBar wouldn't be made aware of that change.
Switching out the video component results in many API changes. The changes are highlighted below:
Class name changes:
- spark.primitives.VideoElement is being renamed to spark.components.VideoDisplay
- spark.components.mediaClasses.StreamingVideoSource is renamed to park.components.mediaClasses.DynamicStreamingVideoSource
- spark.components.mediaClasses.StreamItem is renamed to park.components.mediaClasses.DynamicStreamingVideoItem
VideoDisplay/VideoPlayer event changes:
The new video component's events are:
- bytesLoadedChange : org.osmf.events.LoadEvent
- currentTimeChange : org.osmf.events.TimeEvent
- durationChange : org.osmf.events.TimeEvent
- mediaPlayerStateChange : org.osmf.events.MediaPlayerStateChangeEvent
The old video component's events were:
- close : spark.events.VideoEvent (removed)
- complete : spark.events.VideoEvent (replaced with mediaPlayerStateChange)
- metaDataReceived : spark.events.VideoEvent (replaced with mediaPlayerStateChange)
- playheadUpdate : spark.events.VideoEvent (replaced with currentTimeChange)
- progress : flash.events.ProgressEvent (replaced with bytesLoadedChange)
- ready : spark.events.VideoEvent (replaced with mediaPlayerStateChange)
VideoDisplay/VideoPlayer property changes:
Renames:
- maintainAspectRatio:Boolean has been renamed to scaleMode:String and rather than true/false, it now access 4 values: none, zoom, letterbox, and stretch. See the enum class org.osmf.display.ScaleMode.
- playheadTime:Number has been renamed to currentTime:Number
- playWhenHidden has been renamed to pauseWhenHidden, and it's "tense" has been reversed. So playWhenHidden = true correlates to pauseWhenHidden = false. Also, before we would only pause when the video component was explcitly set to visible=false, but now we detect if the video components or any of it's ancestors have been hidden.
- totalTime:Number has been renamed to duration:Number
New properties:
- bytesLoaded:Number This is a new property not available on the old video component
- bytesTotal:Number This is a new property not available on the old video component
- loop: Boolean this was a property added a while ago on the old video component but not in the original video player spec
- mediaPlayerState: this is a new property that details the state of the video component. See org.osmf.media.MediaPlayerState for all the possible values.
- seekToFirstFrame:Boolean (pending PARB approval) - This is a new property available on VideoDisplay/VideoPlayer. When autoPlay = false, if seekToFirstFrame is set to true, then we will connect to the server to start downloading the video, figure out the size of the video and resize appropriately, and show the first frame of the video. If seekToFirstFrame is false, then no connection to the server is made, there's no implicit size for this video, and the first frame will not be show automatically. By default the value of this property is true. In the old video component, when autoPlay = false, we always has the same behavior as seekToFirstFrame = true. Now it is controllable through this property. Eventually, (not for Flex 4.0), we will most-likely have support for a thumbnail source or a splash screen so the video's preview will show up without making an unneeded connection to the server. The property name may change depending on PARB.
Other changes:
- autoRewind: The default of autoRewind is now true instead of false
- enabled: before we paused the video when the video component was explicitly set to enabled = false. Now we pause the video when the video component or any of it's ancestors have been disabled.
VideoPlayer-only changes:
- videoObject:flash.media.Video property is now a new property on VideoPlayer. It was previously only on VideoDisplay.
- The skin states for the old VideoPlayer were: connectionError, disabled, disconnected, loading, playing, stopped, connectionErrorAndFullScreen, disabledAndFullScreen, disconnectedAndFullScreen, loadingAndFullScreen, playingAndFullScreen, stoppedAndFullScreen. The new skin states are: uninitialized, loading, ready, playing, paused, buffering, playbackError, disabled, uninitializedAndFullScreen, loadingAndFullScreen, readyAndFullScreen, playingAndFullScreen, pausedAndFullScreen, bufferingAndFullScreen, playbackErrorAndFullScreen, disabledAndFullScreen
DynamicStreamingVideoItem property changes:
- bitRate:Number renamed to bitrate:Number
DynamicStreamingVideoSource property changes:
- initialIndex has been added to DynamicSteramingVideoSource
- live:Boolean has changed to streamType:String which accepts values: live, recorded, any. See the enum class org.osmf.net.StreamType for more info.
- serverURI:String renamed to host:Object
- streamItems:Array has changed types to streamItems:Vector.
ScrubBar property changes (THESE CHANGES ARE NOT DONE YET, BUT SHOULD BE DONE SOON)
- bufferedStart will be removed
- bufferedEnd will be renamed to loadedRangeEnd. This property name still may change depending on PARB.
- bufferedArea skin part needs to be renamed. Probably will be renamed to loadedArea. PARB still deciding.

I've got that same problem: iPod Touch 2nd Gen, Apple Component Cables, and an HD TV.
The funny thing is, the cable works fine with an iPod Classic (160 GB) but not for the iPod Touch. Can anyone explain why that is?

Is there presenter v10 for Mac, is video Express the same features i.e. Powerpoint etc etc

is there presenter V10 for Mac, is video Express V10 the same features as windows version i.e. Powerpoint etc etc

The Presenter Video Express is a screen and web cam capture tool. The PPT integration and functionality is Widows only.
You may want to look at Captivate, which has both a Mac and Windows version, and can work with PPT content.

Many folks using Mavericks have bought the playback component from Apple so don't know why you are unable. You don't install it just follow the instructions on Squared5 site.

QuickTime MPEG-2 Playback Component for Mac OS X

Hello my friends
I would like to know if I can install my "QuickTime MPEG-2 Playback Component for Mac OS X" in Leopard ?
I bought this component when I was in Tiger and I wouldn't make any mistake in installing it within Leopard which is working like a charm.
Thanks

Hello Smokerz
I've checked within my Apple Store Acount and the download link is still pointing to the same version as the one I bought... Maybe I shall wait until a new version is available.
Thank you

Home sharing is working fine for musics and videos but not for apps. What is wrong?

Home sharing is working fine for musics and videos but not for apps. What is wrong?

i had the same issue as everyone here after upgrading to itunes 10.x. vista could see xp home share. ipod touch could see xp home share.
neither could see vista home share.
after several hours of authorizing de-authorizing, rebooting router etc, i knew it had to be a firewall thingy with vista as xp was working fine
i went to this article http://support.apple.com/kb/ht2553 and followed the instructions. itunes was already in my vista exception list. on a hunch i deleted the itunes exception and followed the steps to add it again and boom it worked!! i could now see my vista machine from my ipod touch immediately.
something must have screwed up the firewall exception on the upgrade to itunes 10.x
it worked for me, i hope this helps others

Have you ever had video, but no audio in FCP?

I had a friend digitize footage(as uncompressed 8bit) for me on his mac at work. When I import the clips into FCP there is video, but no audio. Audio does indeed exist because you can here it if the clips are opened in Quicktime. Any ideas on getting the audio to play?
Thank You Very Much!!!

Welcome to the forum!
What codec is the clip? If its a muxed MPEG clip, you'll need to demux/convert it to an editable format prior to importing into your FCP project.
To find out what codec was used to make the clip, open it in QT and hit Command j, then click on 'Video Track' to see the specs.

How can I cut some video but keep audio running?

Hello
I once knew how to do this but forgot, and can't find it in any discussions or help files.
I have some shaky, crummy video but the audio in it is good.
I am editing the video, but I want to keep a running audio track from the original DV import.
"Paste over at playhead" is not the answer (unless I got it wrong).
I doubt this is the best way to do it but I am presently copying a clip; extracting the audio; placing that audio back into the timeline under the video; hacking up the video...and hoping the length is close to perfect. (Surely not the way to do it).
Tips? Thanks

David
You know, somehow your explanation made more sense than the iMovie Help file explanation. (Though it has some additional info that touches on what remains a bit of a problem for me).
In any case, thanks. I am using this technique right now. The difficulty that remains for me is how to deal with a short segment of video (to paste) over a 2 or 3 times longer segment of audio. The help info and my own experimentation show that the remaining space gets filled with black. Not very pretty or smooth.
Which leads me to my response to the other person who replied to my post...
*Glo H*
Yes. I am copying the clip so I can have needed video to fill the space as the audio plays. But I'm pretty sure this is not the smart, most efficient way.
(See David's reply).
I am continuing experimentation but am very much open to any other suggestions.
Thanks again.
