O.S. 3.0 scrubber bar in my app?

Hi all, I am working on an educational app (which currently resembles an eBook reader similar to Stanza) and would like to have some advanced audio playback controls.
1) I am curious if it's possible to set up a Scrubber bar similar to that in O.S. 3.0 so that it allows the user to control the rate of scrubbing by sliding their finger down the screen before they scrub.
Is this possible?
For those who don't know what I mean by Scrubber tool I mean the item that is circled in red:

2) Is it possible to have the app remember an audio file's playback position, so that if the user closes the app, the app will remember where they left off?
We will have multiple audio files so it may need to remember more than one audio file's playback position.
Thanks for your help!

I now have a scrub tool with the slider.. but I'm not able to get it to emulate the O.S. 3.0 scrub tool, which allows the user to control the rate of scrubbing by grabbing the Playhead and sliding their finger down the screen.
Anyone know if this is possible in the iPhone SDK?
Thanks.

Scrubber bar still not there

Hi, I've read the posts saying that if the scrubber bar (native iPod app) is gone you can get it back by tapping or double-tapping somewhere on the screen.
What if that doesn't work?

Hello again
Seemed to have answered my own question by looking into some helpful links provided by resdesign. I have another question if I may.
The layout the slider sits in has some other interactions and when I test the page on the ipad the other interactions/buttons do not activate, and the slider is controllable no matter where I touch on the screen. I really just want to contain the interaction of the slider to the related graphic. Can anyone help
kind regards
John

After capture, small grey lines in viewer scrubber bar

I have just captured about an hour of video to FCP 5 and when I open the clip in the viewer, there are 12 small grey lines in the lower half of the viewer scrubber bar, they seem to be equal distance apart. Anyone know what these are? At first I thought it was indicating dropped frames, but during capture FC did not report any dropped frames. Thanks.

For example, right where one of those markers is, the time code goes from 14:59;29 to 15:00;02 and skips 14 59 00 , 01 and 02.
Oh, my, you're new to this video thing, eh? Not a problem, we all were at one time or another, everyone starts somewhere. This is how the two types of timecode work, drop frame and nondrop frame. There's plenty to read on timecode in the FCP manuals. Confusing, we know, try not to let it bug you. Nothing is being lost and a 3 hour clip is the same length in either mode.
On another topic there's an audio delay in the second half this hour long clip, but I'm not going to get into that right here. Thanks.
No, thank YOU. Audio delay can be caused by lots of weird things and many of them are user-caused or don't really exist at all.
Try to get some thick skin, we spend tremendous effort kidding with our forum members. Not everyone can take the pressure.

How to see the scrubber bar in Imovie window

This might sound a little weird, but I don't see the scrubber bar in my Imovie library workscreen--and I don't see any dropdown menu options or icons that would make it visible. Any thoughts? Thanks in advance--C

Thanks again for getting back to me. What I'm looking for is a way to determine the exact time of a location in a clip, either in the clip view or the timeline view. This image seems to indicate that the clip view should have some kind of time bar:
And it seems the timeline view should also have some way of keeping track of time (I can move the vertical white line along the clip in the timeline view, but there doesn't seem to be any way to see at what point the line is; the readout indicates how long each clip is but the number of seconds doesn't change as I move the playhead):
So I'm looking for a way to determine via a clock/counter where exactly I am in a clip. I'm sure it's something simple, I don't know what I'm missing!

Scrubber Bar on iPad issue

When previewing my book on an iPad, I am not able to see the scrubber bar I have set for sound recordings. In the widget, I have show audio as scrubber bar selected. In iBooks Author and in the preview on my Mac, the scrubber bar appears. On my iPad, both when viewed as a preview and when fully exported and opened in iBooks, the scrubber bar only appears as a gray box with an arrow in it. When played, the arrow switches to a pause button. There is also the option to play via AirPlay, but no scrubber bar.
Any thoughts on why this is happening?

I figured out my problem. I had set the size too small. When I increased the width of the box just a bit, the scrubber bar appears.

What is the pink line in the scrubber bar of the viewer?

I'm currently editing a multi cam project and there's a pink line in the scrubber bar of the viewer? At the "in point" of the line there's a triangle on top, at the "end point" there's a triangle on the bottom. Does anyone have any information of what caused it and/or how to get rid of it.
Thanks

Not familiar with a pink line...
This is a split edit marked.
If that is what you are seeing hit option x to clear.

Scrubber bar now works for songs but no longer for podcasts

All of a sudden, my scrubber bar does not move from the start position when listening to podcasts. I if touch it, it will restart the podcast, also, the progress bar does not move, and the time on the podcast stays at 0:00 even if it is playing. Regular fast forward and rewind work fine, and the scrubber bar functions normally when playing songs.

This only happens with podcasts you downloaded directly to your phone and then synced on itunes, right?
Here's what I posted elsewhere...
This has been a problem for me for awhile, getting the --:-- on the scrubber bar, not being able to forward through the podcast. And not just on iphone 4. It happens on my Ipad and happened on my old iphone --so its not a IOS 4 problem exclusively.
Anyway, _I have figured out a rather convoluted solution to this problem_. Bear with me, it's going to seem silly and excessive.
So... when you sync your phone/ipad to your itunes, 1st thing to do is "transfer all your purchases" (if you dont know how to do this, control-mouse click on the iphone/ipad icon when it pops up in itunes)
This will transfer all the podcasts that you had downloaded directly to your phone back to itunes.
Then (and you only have to do this once) make sure "sync podcasts" is checked off under the PODCASTS tab -- the tab related to your phone, not the PODCAST tab for the stuff on your Itunes desktop/laptop.
Then comes the really silly part. You have to manually click on any of the podcasts you want to go back to your phone. The ones you directly had downloaded on your phone and the ones you downloaded through itunes.
They will sync back to your phone and work fine, scrubber bar works now, the time is correct, it lets you fast forward etc...
I have a bunch of podcasts but probably not as many as most so its not that annoying for me to have to manually click on the ones i want back on the phone the right way. I'm sure this solution probably is too silly for those who have tons of podcasts and dont want to have to reclick on every one just because they hooked up to itunes. But it is a solution of sorts.
I"m hoping Apple will fix this little glitch at some point but until then this is what I came up with. Interested to hear if anyone has a simpler solution or if this works for other people too. Thanks.

The same song continues to play what is the scrubber bar and racetrack icon

The same song contunues to play. What is the scrubber bar and racetrack icon?

Covered in chapter 4 of the Users Guide

The racetrack is the repeat function icon. Tap it until it turns white for no repeat.

Scrubber bar displays only fraction of total time

So, I recently decided to add some Ricky Gervais radio recordings to my iPhone's library as podcasts. I downloaded these around 4-5 years ago and at the time used my zune (I know, I know -.-) to play them. So I after I sync them to my iPhone and try to play them, I notice that the scrubbing bar on top is displaying a ridiculously short total time for the podcast. I sort of shrugged it off because I was at work and couldn't do much about it at the time. Now mind you, these recordings last anywhere from 40 minutes to an hour. The time displayed ranges from 2-4 minutes. This wouldn't really be an issue, but it does not allow me to pause or rewind after it reaches the shorter time displayed. The podcast will continue playing if left alone, but once you hit pause or try to fast forward or rewind it will revert back to the end of the 2-4 minutes. This gets to be a pain because then I have to fast forward through the use of the playback speed button in order to reach the place I was at. These files are all .mp3s. I did add them manually to my iTunes library and then change their media type to podcast. The podcasts display regular time when playing on my desktop's iTunes. I recently noticed that the correct time displays for a fraction of a second when I begin to play one, but then switches itself to the shorter time (using the scrubbing bar during the time that it flashes the correct time does nothing as it just starts playing at the end of the shorter time displayed). I'm pretty sure this problem is something I have done on my end, but I'm not sure what that might be. I'm willing to try anything out just to fix this issue.

Yep. That did it. I had iTunes create an apple lossless version of one podcast just to test it out and when I synced it the scrubber bar displayed the correct total time for the lossless version. I'll have to make a day of fixing up my old podcasts in batches. Thanks for the help though, this was driving me batty!

I have trouble getting the scrubber bar to show. How can I get it to show on my screen?

I have trouble getting the scrubber bar to show on my screen. Sometimes it's there and sometimes it's not. How can I get it to show on the screen whenever I want. Nothing in my manual answers that question.

The Users Guide says:
Additional audio controls
To display additional controls, tap the album artwork on the Now Playing screen. You can see elapsed time, remaining time, and the song number. The song’s lyrics also appear, if you’ve added them to the song in iTunes.

Scrubber Bar is Gone!

I went to repeat play a playlist on my iPhone Touch yesterday and realized my 'scrubber bar' doesn't appear on the Cover Art Now Playing Screen. This means I can't skip through a track, shuffle or repeat from where I'm playing. I tried wiping the iPod and re-syncing it, reset all it's data, etc etc - with no luck. The scrubber bar does not show when I switch from the Now Playing List screen to the Cover Art screen..
So I went to my iPhone - same problem!! Am I missing something here? Both devices are on 4.3.1
Thanks,
Ken Toy

Bless you, bless you all. I've been operating without this for months and missing it greatly. When I got a new iPod and it was still happening there, I finally decided to go looking.
Anyone know when this default behavior began and why? I swear there are a number of useful features in these devices which just aren't communicated in a clear fashion.

Scrubber bar gone from mini-player?

I used to like to keep just the minimized window on my desktop instead of the full window, but I'd still have access to the scrubber bar. It seems now that the mini-player doesn't have a scrubber bar anymore. Is there any setting to turn this back on?

Have you tried right-clicking inside the task bar field (in an empty space around the computer clock) - tools and enable iTunes?
Also If enabled:
Edit > Prefrences > Advanced > disable 'Minimize iTunes Window to system tray'

ITunes for Mac lacks a scrubber bar?

There is a scrubber bar in iTunes on my Touch. I thought there used to be one in iTunes on my Mac, but I can't find a setting that gives me one now. I'm using the latest versions of both iTunes and Snow Leopard. I want to be able to see how much time is left in a podcast I'm playing on my desktop and can't figure out a way to do that.

Thanks for explaining that. I never heard it called that.
As Dave says he has such a bar at the top of his iTunes as do I.
I had never tried to use it the way you do but after your suggestion I tried moving the slider on that bar and was able to move to other parts of podcasts.

A scrubber bar question

http://video-excel.com/cpso_flash.html
hi - i am cheating on a scrubber bar i made on the above SWF.
i basically made a movie clip, then added the frames to it to match
the length of the video clip. for example, the video on scene 2
[the scene with the gal signing to you] is about 28 seconds. and
the FLA is set at 30 fps. so i did 28 x 30 = ___ to get the number
of frames needed to be added to the movie clip.
it seems to have worked ok so far, but there's a lot of hit
and miss in trying to get the bar as close to the end of the video.
but i am wondering if there's an easier way to make the green
scrubber bar function precisely based on the playback of the video?
and FYI - i am absolutely horrible with actionscript, so if anyone
can send the script snippet, that would be wonderful.
thanks - deaf guy mike

Deaf Mike,

> match the length of the video clip.
Heh, not sure I would necessarily call that cheating -- it
clearly
works -- but I'm not surprised to read that you're having
trouble matching
up the framerates. The issue here stems from the fact that
you're treating
your video like a movie clip, which happens because you're
laying down your
video actually *in* a movie clip (at least, I think that's
what's going on).
If you externalize your video instead -- that is, use FLV
files --
you'll have access to the features of the NetStream class (as
opposed to the
MovieClip class), which ultimately gets you closer to what's
really going on
in terms of the video itself.
> FYI - i am absolutely horrible with actionscript, so if

> can send the script snippet, that would be wonderful.
For me, the breakthrough in understanding came when I
understood the
concept of classes. Classes define objects -- the things you
use everyday
in Flash, like movie clips, buttons, text fields, videos, and
so on -- like
recipes define a meal, or like blueprints define a structure.
As it is (again, I think so), you've imported a video into a
movie clip
symbol. That means your video's container -- your object --
is defined by
the MovieClip class. Classes generally describe
characteristics of the
object (properties), things the object can do (methods), and
things the
object can react to (events). In this case, I presume you're
relying on the
MovieClip._currentframe and MovieClip._totalframes properties
of the movie
clip (aka "video") in question. Accuracy is going to depend
on the
relationship of the imported video's framerate to the
framerate of your FLA,
which may or may not match up integer for integer.
If you use a different class -- NetStream -- as your video's
container,
you'll have access to a completely different set of
properties, methods, and
events. I realize that none of this may seem easy to follow,
but for what
it's worth, here's something I wrote for AS2 (if that's the
language you're
using) that might jar loose some of the concepts for you.
http://www.quip.net/blog/2007/flash/actionscript-20/how-to-build-flv-progress-bar-part1
Start small, and see if you get anywhere with it. I'm
certainly happy
to answer any questions. And of course, if it doesn't do
anything for you,
that's fine too. :)

Anyone else having issue with ipod scrubber bar?

Anyone else having issue with the ipod scrubber bar? Can rarely get the thing to appear, sometimes it works, sometimes it does not. Then, once it's open, good luck making it go away.
Anyone else notice any funky, non-responsive, inconsistent behavior?

So you're having trouble just tapping the album artwork when a song is playing and the scrubber doesn't toggle on and off?
I'm not getting this funky behavior with 2.1.
