Variant playlist with alternate audio in HLS

How do you play a video with alternate audio tracks on Safari/Quicktime player?
I'm using the Set level manifest as mentioned here : http://tools.ietf.org/html/draft-pantos-http-live-streaming-07#section-8.7
However, only the default audio stream plays. How does not select another audio stream?
Thanks,
Apurva

I'm having the exact same problem... So confused... Why would it have that option if it doesnt do anything? I used Handbrake as well. The 2 audio tracks show up on Quicktime and iTunes, but I cant use em when theyre on my iPod. Please help

Can quicktime play an video track with multiple alternate audio tracks?

Hi,
If I have a video track with multiple alternate audio tracks (say different languages), can a user select the audio track of his choice and play in Quick time?
Thanks,

Does quick time/ safari have this capability?
QT (i.e., the QT structure embeded in current Mac OS/device IOS versions) has the ability to switch between alternative audio tracks assuming the file is properly encoded and the compression format is supported. QT 7, QT X, iTunes, and similar app player GUIs can switch between such tracks during playback but the QT plug-in cannot. In a similar manner, devices like TV can switch between such tracks but an iPhone cannot just as an iPhone can select "Chapters" but the QT browser plug-in cannot but an iPhone file programmed with both chapters and alternate audio tracks can be played back through a TV device and access both chapters and alternative audio tracks.
What I want to use is one video track with alternate audio tracks in a set level manifest and play this using HTTP Live streaming. I'm using the manifest mentioned here :
http://tools.ietf.org/html/draft-pantos-http-live-streaming-07#section-8.7
Since I do not use playlists, I am not familiar with the approach in your example. If I want alternate audio and/or video tracks, I create standalone video files with these features built in. Nor do I use RTSP if that is what you mean by "live streaming" of content. If I want to "stream" the content, I use "Fast Start" files programmed to open in the QT player app which supports these features or create reference or QT Media Link files that do the same thing.
As you mentioned, Safari on my iPhone is playing the default/first alternate audio track mentioned but not giving an option to switch tracks.
Neither Safari nor the Video app GUIs on your iPhone have a built in switching option. The only way to switch to alternate audio tracks is to do so with QT 7 Pro or possibly iTunes before loading or streaming the video file. (Am still speaking about a standalone file here and not a programmed playlist/RTSP switch.)
However Quick time on my Mac machine only plays the audio with the the video stream and not the alternate audio track.
The QT player app GUI only switches between tracks that are stored as part of the standalone file. Basically, QT files may contain up to 99 individual data tracks. In alternative audio videos, multiple audio tracks are added to the file by an editor like QT 7 Pro but only one track is designated as "active." All other tracks are designated as "inactive." The QT player GUI allows the viewer to select which audio track he or she wants to hear and then turns off the current audio track and turns on the selected audio track. Otherwise all active tracks would play simultaneously.
Is there a way to switch tracks on my iPhone on Safari?
As previously noted, the default track can be manually changed by QT 7 Pro or, I believe, iTunes (used to have this capability) before actually loading or streaming content.
Does quicktime have this capability?
As far as I know, only with regard to stand alone files programmed with multiple alternate tracks. I am not a HTML, HTML5, or Java programmer so I assume there may be web alternatives here but they would be beyond the scope of my expertise.
Do you know any free player that can do this?
Again, I don't use either playlists or RTSP so I've never had a need to look for/use alternative players that might meet your needs. I simply find it easier to build files that work correctly in current player app/device GUIs already having these capabilities.
Or the very last option, can I build a player to do this? If yes can you suggest where/how I start?
Once again, I assume this might be possible but not part of my experience since, for my part, easier work flows are available.

How to create a playlist *with* duplicate songs

I have a practice where I need to play a playlist with duplicate audio tracks. The audio tracks are not duplicated in the iTunes app and I don't want to duplicate them as audio tracks. I only want to create a playlist that will play the same audio track at different points in the playst. For example...
Announcement of beginning
Round 1
Announcement of task1
John Doe 1
John Doe 2
3 minute work window
Countdown of 10 minutes
Round 2
Announcement of task2
John Doe 3
John Doe 4
3 minute work window
Countdown of 10 minutes
Round 3
Announcement of task1
John Doe 5
John Doe 6
3 minute work window
Countdown of 10 minutes
Round 2
Announcement of task2
John Doe 7
John Doe 8
3 minute work window
Countdown of 10 minutes
As you can see... I need to be able to duplicate the playlist audio tracks at certain points in the playlist to create the event that I need for that day.
The problem is that iTunes sees that a duplicate track is put into the playlist and doesn't allow it. I end up with this as I can not readd an audio track that I have in the playlist already.

Is there no way to tell iTunes to allow duplicate audio tracks in a playlist?

Smart playlists and playlist folders won't hold duplicate entries, but it should be possible to put the same track more than once into a regular playlist. Go to Edit > Preferences > Advanced and click the button Reset Warnings... iTunes should now warn you when you try to add duplicate items to a playlist, but you should have the option to add the items anyway.

Playlists don't work with separate audio clips

I have a timeline with 8 different clips and chapter playlists set up to play each clip individually and to play them in pairs. This works fine.
But when I add audio to the timeline it goes wrong. I have 8 different audio clips that match up with the video clips. If I view the timeline itself, everything is OK. If I view the first clip's playlist (with the first audio clip) it also works OK. But if I view any of the other playlists, the DVD (and previewer) return me back to the menu as soon as the audio track starts (this is the end action). If I delete any of the audio tracks, the playlists for those videos work fine again.
I also see similar behaviour on another timeline where a second audio clip starts midway: the chapter immediately before the new audio track is skipped in a playlist and the DVD plays the subsequent chapter (there are many chapters on that timeline).
The only solution I've come up with is to burn a DVD with no audio, rip the video, line up the audio tracks I want to use with the video, export them all in one big file and then add that single clip into Encore. It's not really something I want to do, to be honest.
Is there any explanation for this strange behaviour, or is it another bug?
Thanks for any help or pointers towards sorting this out.

I'm with Neil on the 8 separate Timelines. There are pitfalls to grouping multiple Clips onto one Timeline, and even an Audio Unit's difference in Duration can cause issues.
If you do go with the discrete Timelines workflow, you'll just do Playlists, and not Chapter Playlists instead.
Good luck,

Trouble with ATV and Alternate Audio Tracks / Chapter Markers

So I decided to "treat myself" and I got an ATV earlier this week. I for a long time have kept my movies and TV shows organized inside iTunes, and ATV seemed like the logical extension of that so that I don't have to sit hunched in front of my computer to get easily accessed media.
That being said, I've been reencoding a lot of my content for a higher-quality stream for my TV. And I'm encountering a few problems.
I'm using the newest Snapshot Build of Handbrake (which is pretty great) to create my files. I'm ripping them using the ATV preset, slightly modified:
- H264
- .mv4
- 3000kbps
- 2-pass encoding (turbo 1st pass)
- Native anamorphic resolution
- AC3 Dolby Pro Logic II mixdown
- AC3 Passthru
- Chapter Markers
The encoded file is passed through MetaX to add complete metadata and label the chapters. Then the file is stored on an external hard drive attached to my laptop, and added into the iTunes library (while remaining on the external HD, not copied into the iTunes Music folder).
And I end up with a great quality file that looks fantastic on my TV. However, I'm having some problems. I have no options for alternate audio or chapter selection on the ATV. If I open the files up in Quicktime, it has the options right there, plain as day, but they're nowhere to be found on the ATV.
The only thing I can think of is that it's because I'm streaming the files, not storing them locally on the ATV, but I can't find any yay or nay on that and I'm not quite sure why that would make a difference.
Can anybody lend a hand on figuring this out?

I tried to follow what you are saying but not enough information here. I can only tell you that using HB on .m2t files or mpeg2 files user must uncheck Chapters in HB preferences to be able to use Chapters forward and back with the Apple remote and ATV.
I know this does not address your problem but may give you some insight to help. When ripping I do check box chapter markers. Maybe its MetaX doing the problem I don't use that software.

Export QuickTime file with new audio and maintain the file size and quality as the original.

I shot some footage for a client yesterday and ran into an issue. To make a long story short I have QuickTime mov files shot with my Panasonic GH4 that have a buzzing sound in the audio track. I have clean audio from a recorder that can be sync'd. Is there a way for me to do this for the client and deliver them as the same QuickTime file but with the clean audio and keep the file size close to the original and not have quality loss in the image?
If so I will probably put all of the spanned clips together from each interview and sync the audio before delivery. I am just not sure which codec will give the client the same quality footage compared to the originals and not have a massive difference in the overall file size. They did request that they be Quicktime MOV files though so that is a must.
I don't see this as an option in the codecs in the export settings in PP, but is there a way to export as ProRes or another MAC native codec that will save them from having to convert it on their end? I am on a PC with Adobe CS5.5 so I am not too familiar with MACs, but from what I understand they would need to convert the files if I sent them straight out of the camera.
I found some related search results for this but they pertained to "Best quality" for export. I am not sure how the varying options work but I don't want to create files that are considerably larger, just not less quality.
If anyone has experience with this it would be greatly appreciated.
Thanks,
Cole

Here's the workflow: I imported the video footage into iMovie '08 and did my edits. Then I exported it (share) to my desktop with compression set @ 740 X 480. Then I used QuickTime Pro to fix the audio track. The file plays perfectly with both audio tracks working. It's a QuickTime file (.mov).
I hope this jars any replies as to why the file when uploaded to my iWeb gallery drops the second audio track.
Hmm,
Jack

What's wrong with my audio configuration?

When I try to open iTunes, I get a message window that says, "iTunes has detected a problem with your audio configuration. Audio/Video playback may not operate properly." After pressing "Okay," iTunes will open but will not play any sound. I tried re-downloading Quicktime like suggested in other posts, but this did not help. Now I'm at a lost. Any suggestions?

I tried un-installing Quicktime and iTunes and then re-installing both and now everything works fine for me. Have you tried that? Even all of my songs are still in my playlist! *so happy*
Good luck!

2.2 Music Video Playlist problem-no audio (every other MusicVideo)

I updated to 2.2 over the weekend so that I could have MusicVideo Playlists (plus all the other enhancements). BUT, the audio on the musicvideos only plays on EVERY OTHER musicvideo. Each one works individually. The playlist works properly on the iMac that syncs to the AppleTV, but the audio only plays on every other one.
I've tried mucking with the Audio settings (the auto-level check item), but to no avail. If I start on the first one, only items 1, 3, 5, .... have audio (video is fine). If I start on item 2, then the even numbered videos have audio.....
Any idea what's going on here? Suggestions?

just my 2 cents...but i have about 550+ and I havent seen (heard) a problem w/ any of them yet. Encoded almost all of them with either iSquint or VisualHub on the mp4 setting...with or without h.264

Creating Alternate Audio Streams

Hi guys,
I've worked with DVD Studio Pro before and I'm currently working on this project where I'm supposed to make a DVD that will play the film in either standard or dolby 5.1 audio. I've been trying to figure out how to make it use alternate video streams without just making two sets of the film in its entirety and I just can't understand the manual at all with all the talk about stories and whatnot. Can anybody tell me in simpler terms how I can create a dvd menu that will allow the viewer to choose to play the film in either normal stereo audio or dolby 5.1 audio?

Create both audio streams. Drop them into tracks 1 and 2. Now you have 1 video track with 2 audio tracks the user will be able to choose from while the video is playing. When you create a menu button, the button Inspector allows you to not only set a buttons target but will also allow you to set which stream to play.

Audio Commentary aka alternate audio file for movie.. How?

Hi folks,
I love this discussion group btw... awesome...
So, I've got my feature film done, we did a 1 week run at the theatre now, we are almost ready for our DVD release but want to do one of those really cool Director Actor commentary / alternate audio files for the movie. Is this done in FCE or iDVD? and any tips?
Best Regards,
Mark

... I think there is a workaround with FCE + iDVD.
You could duplicate the original sequence in FCE, then add your alternate audio to the timeline of the new sequence. (Record your commentary and add as a 2d audio track (say, a3/a4)). Raise & drop the audio levels appropriately across the length of your regular and alternate audio tracks. Export the resulting video to QT Movie and import it into iDVD along with your original Movie.
You will now have 2 versions of your Movie & can put them both in a single iDVD project (of course, subject to the limitations of the total length you can put on a DVD (~2 hours for a single layer DVD, ~4 hours on a dual-layer DVD.) Or just put them on separate DVDs if your Movie is too long to fit both on a single disc.

Manuel slide timing with an audio track

My wife is a professor and she is wanting to post podcasts of her lectures. I am trying to figure out how to include her Keynote '08 slides in those podcasts. Is there any way in Keynote '08 to add an audio file and still have manuel timing of the slides? Obviously, the slides are going to need to be displayed for varying amounts of time depending on how long she talks about the subject of each slide in the audio file. I have figured out how to do the record function and record varying timing for slide transitions. But that also picks up noise from my computer microphone. I already have the audio as a file. So how can I record the slide transitions so that they sink with the audio file without getting unwanted noise recorded? Should this be accomplished in Keynote, or is there a way to change slides at the proper times in Garageband?

I believe you would have to break up the audio and place a clip on each slide. You can have one audio file for the whole keynote presentation, but if the timings change it would be better to use just the sound clip you need for each slide. You could do this in garage band and import them through the media pallet.
Hope that helps.

Error - itunes has detected a problem with your audio configuration...

Can anyone help me with this one?
"itunes has detected a problem with your audio configuration. Audio/video may not playback properly."
I can get into itunes - but nothing plays - not the radio - not my playlist.
Please help!

Then you may have a startup item (an item that starts up when your computer starts up) that is interfering with iTunes/Quicktime. Try following the advice here and seeing if there's anything starting up that doesn't need to be:
http://www.g4tv.com/screensavers/features/38454/ManageWindows_StartupItems.html
Be careful of what you remove.
Also, if you have any sort of USB or such audio hardware, try removing it and trying again.

Can I create playlist with only music currently on my macbook drive?

I have music on my macbook as well as on an external drive. I don't want to fill up my internal drive with all my music.
It's frustrating though when I open itunes while away from home and try to play music. Chances are I'll try to play something that is inevitably not on the computer. What I'd like to do is create something like a playlist or something that is directed to my internal music folder that I can reference when disconnected from the external drive so that everything listed is definitely available to play.
Is this possible? I've tried playing around with smart playlists etc but so far no luck.
Any ideas or help would be greatly appreciated.
Thanks!
