IOS 5 bug in double speed playback

There is a newly introduced bug in iOS 5 with regard to playing podcasts at double speed (using the little 2x symbol in the top right).
The playback works just fine and it is a great way to consume a lot of podcasts quickly, but if I make a phone call when the call ends the podcast continues, but at normal speed. The screen still shows 2x, but it is playing at 1x. I have to press the button a few times to cycle back to 2x again, where it then is back to doublespeed.
I could not see an easy way to report a bug, so I am posting it here in the hope of getting it to the person that needs to know and can fix it.

Ok correction: this problem has occurred only once. That I found nothing can be clicked in app store.app. But right after I quit and get back, everything looks fine. Dont know why it happened at first, even dont know wheter it will happen again.

Double Speed Playback - Is the Possible in LE

I have to scan a several hours of audio captures from Mini Cassette.
The audio is recorded on a dictation recorder, and some of the recording is at 1/2 speed, and other times it is at normal. I captured the tapes as is at 1/2 speed setting (which is what most of the recording is at) and just captured the tapes until the ends. Now I have to scan through all the captures to find the spots where the recorder was set to normal speed.
I would like to be able to review the audio similarly to how I can speed up a track in FCP. Even if I could speed up the track 2x, it would cut my scanning for pitch changes (from changes in tape speed) in half.
I know I can use Shift-period to fast forward, but that SKIPS over audio, which would result in my not hearing shorter sections of audio that I need to find.
Once I find all the faster section of audio (which would actually sound Slooooowww), I know how to adjust the pitch. I am just hoping there is any easy way of finding the faster audio.
Any help or suggestions would be greatly appreciated.
Thanks

Thanks Jorge.
I ended up bringing the aif caps into FCP. Took only about an hour to scan through 3 hours of audio, cut up the fast audio, apply 200% speed, export back to aif and burn the CDs with iTunes.
Seems like such a simple function to be able to perform. Even FCE has it. Seems unthinkable that LE would not have such a basic function.

Why do my quicktime movies playback at double speed? Please help

Hello all, this is my first post.
For some reason all of the sudden my quicktime movies that are 2 months old or older playback at double speed although the sound plays back as normal. Any movies that are less than 2 months old are ok. All these videos have been taken with my digital cam which records files in mov. Also any of these files which i convert to flash also play back 2 time faster when i select the converted swf file. Please help as i have hundreds of files which are affeceted. Any new clips i record playback fine.
Also I copied and pasted a problematic video on my wifes newer pc and the clip still has the same problem.
Thanks in adavance

I think I figured it out.. didn't see that you could choose what type when importing.

Double Speed (2X) on Nano 6G Slow

I have noticed that the double speed mode for podcast playback is only about 10% faster than normal speed. My iphone plays back podcasts at much faster rate. Something is wrong with the Nano's double speed mode. I've read other's complain about this problem.

Hi Jane,
Thanks for writing this as I have been encountering the same thing myself.
I wanted to make sure that I am understanding you properly. Isn’t 2x supposed to be 2:00 played for every 1:00 elapsed? I think I might be doing the math wrong.
Regardless, yes I have noticed that he 2x isn’t really 2 x however you define it. I have never really liked the iPod functionality and use a program that speeds up playpack permanently. I like transcribe, but I’m sure there are other programs.
Regards,
Geoff

Is it possible to play video double speed?

Hi All.
Is it possible to play video file or video stream double speed?
I've never seen the flash player. Please show me the way.
Thanks in advanced. and sorry for my poor english.

Is it possible to play back video at double speed, but keep the pitch normal? How about playing back at a fraction of double, say, 150% speed?
No, not that I'm aware. Yes; try Shift+L (for forward play) and Shift+J (for reverse play). Start playback with L, and then tap Shift+L; that should increase speed in 25% increments, and you get a number of steps before it tops out. You can do it from a paused state, as well, and get fractional slower-than-realtime playback--that's very helpful, as well.

[SOLVED] Chromium + pepper = Video @ double speed

I am using the latest stable chromium, with the pepper-stable package from the AUR recommended in the Chromium wiki.
I moved to Chromium as Flash is no longer being developed for Firefox....And Firefox 26 crashes a lot, and randomly, including with all plugins removed. So It's a problem right now.
As the subject mentions....I am getting weird video issues. Usually, the video plays back at double speed, with the associated spastic audio output. Here is an example: Ref: http://www.youtube.com/watch?v=smCQ2g9L7PU.
This used to play fine in Firefox with the old flashplugin.
In my porting process, here is what I did:
With no browser open:
a) "sudo pacman -Rs flashplugin"
a1) Verified that flash was no longer operating in Firefox.
b) "sudo pacman -S chromium"
c) "yaourt -S chromium-pepper-flash-stable"
d) In chromium: "chrome://plugins" to verify that flash wasn't showing up.
Arch x86_64 (current), NVidia GTX-660, using the nvidia drivers from Arch...extra. (rev 331.20) vdpau is installed in both the 64 and lib32 variants.
I have tried disabling hardware acceleration in the pepper-flash plugin, restarted the browser and retried. I have tried enabling hardware acceleration, restarted the browser and retried.
Playback seems unaffected in either scenario, and remains unusable.
Gnash has never performed properly for me in any scenario where I've tried it. So Gnash is not an option. Gnash has a long way to go until it is ready to be a good drop-in replacement for an official "flash plugin".
So for now, I have to use the smtube for smplayer to view YouTube/major news site videos properly.
I am requesting, please, some assistance in fixing my video playback issue in Chromium.
Sincerely and respectfully,
Dave
PS: I'm curious, why does the firefox community appear to be sitting on their hands when Adobe has made it clear for a long time that Adobe Flash for linux is being abandoned as of 01-JAN-2014? I would have expected some really heavy programming resources to be assigned to gnash to make it better, or write some sort of wrapper for the chromium pepper plugin....for official Adobe support.
Is there another reliable flash playback mechanism that I am missing all together?

I agree with ewaller (the new html5 player for youtube is good) but to answer your question I had a similar issue with pepperflash and if I recall correctly it was related to sound issues. I do not remember which package solved the issue but here is the alsa / pulseaudio packages I have installed:

Saving m4a or m4v as new file at double speed

Hi - I know I can listen to or watch an m4a or m4v file at double speed in QT7 using the A/V controls, but is there a way that I can save as or export the file at double speed? I want to be able to replay it at double speed on my ipod.
Thanks

A/V control settings are not saved with the file except for playback in QuickTime Player (and only that machine).
In order to "trick" the QuickTime Player app to play the fie at double (or any other speed) you need to make a new file. You do this by adding (scaled) your source file with a "dummy" file.
The dummy file represents the "time" you wish for the source file to display at your desired playback speed. I use audio only files to keep things simple.
Once you add (Scaled) to a shorter duration the video and audio tracks will playback at a different speed.
You "extract" via the Movie Properties window of QuickTime Player Pro.

Hit Play video plays about double speed

When I play the video I am working on in the timeline, the video starts normal (for about a second) but then starts racing at about double speed. If I turn the external video to off under the "view" pulldown menu, the playback is normal.

Please give your full system specifications, what computer, what drives, what camera or deck, how everything's connected, what settings are on the media, what settings you're using in Final Cut, and finally what version of the software, of the OS, and of QuickTime you are using.

1st movie uploaded to youtube plays @ double speed

Using a 4-year-old 13" MacBook with iMovie HD 6.0.3 I created a 36-second video which, when uploaded to youtube, has the video playing at double speed but the audio playing normally until the audio gets cut off since the video now has been reduced to 19 seconds in length.
On the youtube help forum I see others who have had a similar problem are being asked for info obtained from a freeware app called MediaInfo which gives all the particulars on codecs, I guess, but that software is not available for Mac.
Afraid I have not kept up to date on movies—am doing this for a friend and have no idea what to do. So far no one has responded to my query on the forum. Any direction would be appreciated.

There aren't any settings in iDVD that would increase or decrease the speed of a video, so you may want to take a look at the Quicktime movie properties to see if it was compressed by cutting the frames per second in half (eg, 15 frames/sec rather than the standard 30 fps).
If the original is 15 fps, you might try running a sample through MPEG Streamclip, iMovie, Quicktime Pro, Roxio Toast... to see if one of those can add frames back into the video so it's the standard 30 fps. I've not encountered this before, so don't fool around with your original and search the archives here and over in the forums associated with the software mentioned.

Why doesn't Quicktime play audio in double speed any longer?

Until recently, a person could click on the FF button to play a video/audio file in double speed and hear the audio. This was especially helpful when watching/listening to lectures. Now when you play in double speed there is no audio. What happened? Is there a glitch in the software? I hope the feature is returned to its former design.

Finally figured it out the solution! (This only applies to Mac users.)
Firefox 3.x ran in 32-bit mode and Quicktime 7.x runs in 32-bit mode, so the two programs worked just fine together. The new Firefox 4.x, however, runs in 64-bit mode, so the 32-bt Quicktime 7.x plug-in no longer works correctly.
Luckily the fix is simple: just switch Firefox 4.x from 64-bit mode down to 32-bit mode. Here's how:
[] Close Firefox 4.0
[] Highlight the Firefox icon in the Applications folder
[] Click COMMAND-i to open the Get Info window
[] Click on the box marked: OPEN IN 32-BIT MODE and close the window
[] Launch Firefox
You can now save Quicktime files as before, assuming you have Quicktime Pro.
[] After closing Firefox, you can un-check the OPEN IN 32-BIT MODE box so Firefox will once again run in 64-bit mode.

N95 Music playing at double speed

Double Speed Rendering in Final Cut

I am having an odd problem with Final Cut 6 that used to just happen when I would export to "current settings" but has now migrated into my preview renderings.
When I render, the video plays back at double speed, and audio renders fine. The result is half the video render is double speed and the rest is black. Very annoying and I cannot properly edit this way.
Any help will be greatly appreciated.

Yes, when I import my footage, the line is grey and not red and plays just fine. However, if I export and use "Current Settings" the rendered file will come out double speed. If I add an effect and it requires a rendering, the preview will render and double speed. If I can figure out and fix what is doing this, my life will be a whole lot less stressful.
BTW, the funny thing is, if I do NOT export using "current settings" but rather choose HDV 1080i60, it creates the new file just fine. :-/

Double Speed Audio on podcast and audiobook ios5

I'm getting double speed audio on podcast and audiobooks after upgrading to ios5. I restored my ipad but no luck! I have lectures and educational materials I listen to and it's driving me insane that I am unable to listen to it in a normal way. Any fix?

iPhone 3g you say? It might be having trouble playing an Audiobook at 2x. Mine seems to run at 2x.. How's your half speed? You should try give your phone a restart... it might free a bit of memory on the ram.
