[bug?] playback issues with QT browser plugin, any workarounds?

I've noticed a playback issue with media files using the quicktime plugin (currently v7.1.3) with Firefox 1.5.0.x and now Firefox 2.0 on Windows XP (SP2):
Description:
When I open a media file in a separate tab or window, audio playback cuts out when I switch focus away from the tab or window (i.e. when it runs in the background). When I put the tab/window in the foreground again, playing resumes.
Reproducible: Always
Steps to Reproduce:
1. Open an mp3 file with quicktime plugin in a new tab
2. Switch focus to some other tab or firefox window
Expected Results:
Audio playback should continue in the background.
Actual Results:
Audio playback cuts out and resumes once you click on the tab containing the plugin or if you hover over it with the cursor. The cutting and resuming out doesn't happen right away but after a short delay, suggesting that it might have something to do with thread prioritization.
The file is completely buffered by quicktime, this is not about connection speed or bandwidth issues.
Opening the link to the same file with right-click->Open Link in External Application works well.
Someone else has filed a bug report against Firefox about this issue here:
https://bugzilla.mozilla.org/show_bug.cgi?id=339449
I wouldn't be surprised if this turns out not to be an issue with Gecko but with QuickTime.
Can other users confirm this on XP? Is this a known QuickTime bug? Are there fixes or workarounds?
Windows XP

Yeah I had that thought as well but no joy. It works for the player but it doesn't solve my plugin problem. It really seems to be something about prioritizing, the way the audio cuts in and out - notice how it takes a few fractions of a second before a process loses its CPU cycles when you click away from it? You can observe this with System Monitor on the Mac or Linux or process explorer on XP. That's how the audio is cutting out and back in. I still think it's probably a bug/'feature' either with Gecko, the Firefox browser engine, or with the QT plugin..

  • Zen - AAC: Playback issue with long songs (± 15 min.)

    Hi,
    I made some tests with AAC Itunes plus files, and I've experiencing playback issue with long songs (when it's about 5 minutes or longer, like the second movement of Beethoven's third).
    During?playback, there is random artifacts added, never at the same place.
    I cleaned up my Zen 6 Gb and even formated it, and the problem still occurs. The latest firmware is installed.
    Is this issue has already been reported?
    Thanks.

    The Zen does in fact support AAC playback, but it's tricky--I've been dealing with this issue for a while, and I think it's finally solved. First of all, when you say "skipping," do you mean that the track skips ahead further into the same track, or does it skip to the next song with an error message like "There was an error with the audio file"? My problem was with the latter. There are a few possible solutions:
    . Delete the erroneous track from your Zen, then re-transfer; in my experience, this corrects the problem, although sometimes it takes a couple of tries.
    2. Make sure your AAC file is in iTunes Plus format (you can choose it in the ripping options in iTunes).
    3. If you haven't already done so, upgrade to Windows 7. This means upgrading to WMP2, which recognizes AAC files and can transfer them to your Zen. It also means you can download a version of Creative Centrale (from the Creative Support site) specifically for the Zen, which replaces the Zen Media Explorer and Creative Mediasource, and which seems to handle AAC transfers much better (so far, I haven't noticed any of the playback errors, but you never know!). By the way, WMP2 and Creative Centrale will also transfer album art easily to the Zen.
    Hope this is helpful.

  • Bluetooth headphones playback issues with iOS 6

    Has anyone been experiencing some playback issues with the latest iOS 6 and Bluetooth headphones?
    A few weeks ago, I bought a pair of Sony's MDR-1RBT Bluetooth headphones and ever since I updated my iOS devices (4S & iPad 2), playback of tracks has been lagging for the first few seconds. Whenever I choose a song on my iPhone or iPad's player, I just can't hear its first 3~10 seconds. I've contacted Sony about this issue and they bluntly replied that it's Apple's issue, but when I contacted Apple, they referred me to their Bluetooth connectivity site. In other words, my problem still hasn't been solved.
    Could anyone help me solve this frustrating issue?
    Thanks.

  • Hi, my email is saying that there is issue with I cloud. Any ideas?

    Hi, my email is saying that there is issue with I cloud. Any ideas?

    There is a server issue with iCloud email right now effecting some users (see http://www.apple.com/support/systemstatus/).  You'll just have to wait until they get things fixed again.
    Hotmail doesn't use iCloud's mail servers so it wouldn't be effected by this.

  • I upgraded to Firefox 6 random websites are using illegible fonts from my computer instead of the default. No issues with Firefox 5 or any other browser I use. Each time I open Firefox or reinstall it a different illegible font appears. Please help.

    Firefox 6 using incorrect fonts.

    When I delete the font that keeps showing up as the default, a new illegible font appears. The fonts are not 'garbled' they are just decorative typefaces that are being grabbed from my computer. I have never had an issue with my fonts on old Firefox versions or other browsers like chrome, safari, etc., so I don't think the issue is my fonts. I also don't want to have to delete all the fonts off of my computer. I uploaded another photo of when I deleted the font that was appearing before. Please help if anyone has found a solution to this problem with Firefox 6+ :/

  • Anyone having vimeo playback issues with Safari 5.1.10 running OS 10.6.8?

    Since upgrading to Safari 5.1.10 for snow leopard I've notice play back issues with some of my video's posted on vimeo. Video pops up or down in brighteness and contrast and in one case goes all pixelated for one shot and back to normal after that.
    http://www.marcosdurian.com/Five_Hours_South.html
    @ aprox: 02:07-02:11 (brightness/contrast pop) & 03:38-03:41 (sever pixelation)
    http://www.marcosdurian.com/Narrative.html     (Northbay - the first clip)
    @ aprox 00:28-00:50 (brightness/contrast pops)
    The video files playback normal in FireFox, Safari 6.0.5 on 13" Macbook pro. Also plays normal on iPhone 5 w/ ios 6. The files also playback normal on the vimeo website when viewed as flash player but when switched to HTML5 Player the issue is back.
    Please advise.
    thx

    I looked at the first one - I see the same behaviour  here on 5.1.10
    When viewed in Safari, the vimeo iframe code is defaulting to 'HD'  from the several HTML5 versions of video available - the oddness around 3.38 (screenshot below) is visible on that version in any browser, or even if downloaded & played in quicktime. Firefox defaults to Flash, here anyway. Switching 'HD' off in the player, loads a different file, without the problems.
    I haven't looked in Safari 6 - but it's presumably using a different file.
    Vimeo's conversion seems to have slipped up.

  • Weird 4k playback issue with Open CL

    So I am in premiere CC 2014 and just installed an AMD r9 280 3 gb card. When I hit play on my 4k timline 1/4 res my CPU goes to 100% with terrible playback like 3 fps. The GPU at this point is idle doing nothing at all. Then If I let it play for about 5- 10 seconds suddenly the gpu kicks out of idle to about 50 percent usage and my cpu usage drops to around 50 percent usage. When that happens I get perfect playback. So it looks to me that at the begging of play back the GPU is not helping but then kicking in later. I should also note that if I turn off open CL and just use the CPU I can playback 1/4 res perfectly smooth. Also the footage is on a raid so I am not trying to run this off a single drive. Any ideas what is going on? I was on a 550 ti earlier and did not have this issue with cuda. I just found this 280 open box for 179 so I figured I would give open CL a go and upgrade my gpu.
    System specs
    AMD FX 8350 4.0 ghz
    32 Gb Ram
    R9 280 3gb
    win 7 64 bit
    Premiere CC 2014
    8.0.0
    Edit: I also would like to add I am gonna test it in premier CC now to see if the issue is a 2014 bug.
    Edit: Only happens in 2014. Interestingly enough CPU usage still goes to 100 percent in CC and the GPU does some work but playback is flawless.

    Hi Jim,
    Thnaks for your feedback.
    Here is a link to download some footage : WeTransfer
    But you know, I done some test this morning. If I put my footage on my SSD system or on my NAS with RAID 5, no trouble with playback.
    But if I let my footage on my  Raid 1 Media volume  (mirroring), the problem still be here... I think it could be the disk speed... What do u think about that ?

  • Playback Issues with multiple framerates and Blackmagic Decklink 4K Extreme

    I recently swapped by AJA Kona Card for a Blackmagic Decklink 4K Extreme in order to get external monitoring in DaVinci Resolve.
    I'm working in a 1080p 23.976 project that includes some 29.97 SD and HD footage. When loading this 29.97fps footage into my source footage, I periodically encounter frozen playback (The play triangle in my toolbar becomes a square symbol and remains that way). From there I am unable to playback any footage in any timeline, and requires a full system shutdown to return to normal! The problem is seemingly intermitent, with successful playback happening sometimes.
    The 29.97 footage was DVCPRO, I attempted to transcode to Prores to troubleshoot. No dice. I believe it to be an issue related to the Decklink's inability to handle multiple framerates on-the-fly but wanted to submit here, too. I've also experienced intermittent sync delays on my broadcast monitor.
    Decklink Driver 10.0
    Premiere CC 7.2.1
    Mac OSX 10.9.2 (same problem pre-mavericks)

    Hi Andy,
    You should not have any issues with Blackmagic handling multiple formats on the fly. However, I believe the frozen playback issues your describing is related to the Desktop Video 10 driver. I suggest rolling back to 9.3.3 for the time being. Blackmagic is looking into this issue now.

  • JSPWiki - Attachments - issue with IE browser

    Hello,
    We are having issues with uploading and downloading attachments using JSPWiki using IE browser.
    It works perfectly with Netscape/Mozilla/Flock browsers.
    jspwiki.properties -> we set the following attributes:
    jspwiki.baseURL = http://localhost:8888/JSPWiki
    jspwiki.referenceStyle=relative
    jspwiki.attachmentProvider =BasicAttachmentProvider
    jspwiki.basicAttachmentProvider.storageDir =C:\\Data\\jspwiki\\NewJSPWiki
    With the above settings, when using IE browser, it still uses absolute path when file is uploaded and shows href'd attachment name with target as:
    http://chq006103:8888/JSPWiki/attach/JSPWiki%20Welcome/C%3A%5Cinnovatorlille93.jpg
    Whereas in Mozill and other browsers - it correctly shows href'd relative url:
    http://localhost:8888/JSPWiki/attach/JSPWiki%20Welcome/innovatorlille93.jpg
    When we upload a file, it is uploaded under the full name (the full absolute path of the file (from C:\.....<filename>)) - only when we use IE browser.
    This does not happen with the other 2 browsers.
    Thus, we are unable to download the file.
    Any immediate help is highly appreciated!
    Thanks!

    Perhaps ask the people at JSPWiki? And stop crossposting

  • Video Playback Issues With Apple TV3 Running OS8

    I have two Apple TV3s (Both Pre 2013)
    One updated today to the latest OS8, the other still running the previous OS7.1.2
    Now when trying to play virtually any of my own MP4 videos the OS8 firmware version Apple TV3 refuses to play the file.
    Apple TV simply displays "An error occurred loading this content" (retrying simply displays the same error again)
    If I then use the second Apple TV3 (running the older firmware OS7.1.2) and try to play exactly the same files from the same iTunes library the file will play back correctly.
    So far the OS8 Apple TV3 is unable to play over 95% of the video files it could previously play prior to the firmware update.
    The odd file will play but these files are of differing resolutions so don't appear to share anything in common. It is always the same files that will or wont play.
    All video files are Profile 4.0 or lower and contain the required audio tracks.
    I am running iTunes 11.4.0.18 (Windows 8.1)
    Prior to the update every video file played correctly (on both Apple TVs) and the second Apple TV3 (using the earlier OS7.1.2 firmware) still plays the exact same files correctly.
    Music files are unaffected and playback correctly on both Apple TV3s.
    The latest firmware update appears to have corrupted the video playback of the Apple TV3 in some way.
    I have even tried a complete USB restore of the OS8 Apple TV3 but this has made no difference.
    Has anyone else experienced MP4 playback issues since updating their Apple TV3 to OS8?
    Thank you in advance.

    After further tests it would appear that Apple TV 7.0 (OS8) firmware is unable to play any video file with NO CHAPTER markers.
    If I use MetaX to simply tag an unplayable MP4 file with a single chapter, that file will now play correctly using an Apple TV3 running Apple TV 7.0 (OS8). If the single chapter is then deleted the same file reverts to being unplayable.
    In previous versions of Apple TV firmware any video file with NO CHAPTER markers could be played correctly and the Apple TV would automatically generate chapter markers at equally distributed time gaps.
    For some reason Apple TV 7.0 (OS8) firmware appears to have removed this auto chapter marker feature so if a file has no chapter markers the Apple TV will now consider the file as invalid.
    With MetaX it is possible to manually generate additional chapter markers so you can still skip through the file rather than only scan.
    iFlick for Mac should I suspect be able to do the same thing.

  • Horrible playback issues with iTunes 8 and Airport Express over Wifi

    Hello folks,
    I just upgraded to iTunes 8, and since then, I've been unable to get good playback from my Airport Express with iTunes on my Macbook Pro.
    I get between 5-30 seconds of continuous playback, then a hiccup, ad nauseum, ad inifintum. A five minute track usually ends up taking six-seven minutes to complete, and it's like listening to a CD skip.
    Both the Macbook Pro and the Airport Express are communicating over 802.11n, and worked well before the upgrade to iTunes 8. On my older, slower, crappier Powerbook which only has 802.11g but runs iTunes 7 (in the same room, about two feet from the other laptop), playback is rock solid.
    I've noticed when I monitor the WLAN interface on my MBP with 'netstat -in', I'm seeing a lot of Ierrs, but there's nothing in any of the system logs to indicate a hardware problem (yet, anyway).
    Has anyone else had this issue since upgrading? Should I be looking to get my WLAN NIC fixed, or is it an issue with iTunes 8? Are there diagnostic applications I can use to perform hardware confidence tests on the WLAN NIC?
    cheers,
    Klaus

    My AirPort Express optical out has this problem as well, stutter and very bad sound. But only the new 802.11n modell. A older 802.11g model works without a problem.
    It worked well until I upgraded to iTunes 8, I bought in in May.
    I just had my AirPort Express 802.11n replaced under warranty by Apple but the new unit has the same problem.
    Everyone who is using the optical out and have the stutter problem needs to write to Apple about it so they realize it's a problem and fix it.

  • Quicktime 7.2 has a playback issue with Athlon XP processors

    Using a 640X480 h.264 quicktime video (aac audio) I have tried to do playback on 4 different Windows XP SP2 systems. They each have an Athlon XP 2800+ (2.1Ghz) processor in them. Each system had various sound cards and video cards (nVidia and ATI). They each had around 1 Gigbyte of memory. These systems would stutter badly while trying to playback these videos and uses 100% of the cpu.
    The same videos played on a 2.4Ghz P4 system use about 75% of the processor and playback smoothly. On a Athlon 64 2.21 X2 (using only 1 core) the videos playback using an average of about 25% of the cpu.
    The AthlonXPs are all barton or Thoroughbred cores, so they have mmx, sse, and 3dnow. All video/audio drivers have been updated to the newest.
    I have messed with all of the video acceleration settings and audio settings (wave only) with the same effect.
    Is the h.264 codec just not optomized for this cpu? Are these cpus missing some sort of SIMD set that quicktime needs? Like SSE2?

    Odd. I've been tracking reports of the performance problems or system crashes involving playing a video, and hadn't noticed a specific spike hitting folks with AMDs/Athlons. (If anything, it's been most closely related to Intel.)
    Just doublechecking something. In the course of your checking on the Video settings, had you looked at disabling your Direct3D acceleration?
    (Usually, an issue with that manifests as a green screen when playing the videos, or seeing blotches of pretty colors rather than normal video, or "washed out" pale video rather than the sort of performance issues you're getting, though.)
    Is there a Conexant AC chip on any of the systems? Sometimes the power management settings on one of those can cause odd playback symptoms in similar ways to what you're describing (although it's kind of rare by comparison with the nVidia SATA controller issues or the Intel Matrix Storage Manager RAID controller issues).

  • DVD Playback Issues with Dual Layer media

    I have been using DVDSP for years now, and have rarely had any issues with burning my final projects to DVD. Any playback issues have usually been issues with players and +or-R media.
    I have recently upgraded to a MacPro, and have been really stoked about being able to burn to Dual Layer media. My previous G5 didn't have a DL burner.
    I have a large project that fills most the disk, and everything seems great in the software, and when playing the media files on the computer. But when I burn to disk, I have huge issues with playback on different DVD players, computers, etc. I have stuttering with menu's, freezing, and stuttering with playback of video.
    I read that the issue could be because of the speed I'm burning at in DVDSP, so I saved as a disk image, and used disk utility to burn at a 4x speed. This seemed to help, but when I got to the end of the movie I had huge issues with stuttering/playback quality. So I burned another copy from the same disk image, and it wouldn't even play in my DVD player.
    When I open the Video_TS folder from the DVDSP Build, and play right off my hard drive in the DVD software player, I don't have any of these issues.
    So I'm guessing my problem is either my DVD media I'm using, or the burners on this new computer. I've burned DVD's on both burners (yes I have 2) and I still have the same problems.
    I am using Memorex DVD+R DL and they are 8x.
    Can anyone offer me some advice here. I really wish I could just hit burn and have a disk work. DL media isn't all that cheap and I don't know how many coasters I can make and keep my sanity.

    I used compressor and I used the DVD: Best Quality 90 Minutes setting. The bit rate is avg 6.2 and maximum 7.7. And yes I used ac3 audio.
    When you say lowest speeds possible... shouldn't a burner that says it burns at a speed work at that speed? I'm cool with burning at a lower speed to get this thing to work, but why have a burner that burns DVD DL at 8x speed, when it doesn't work? Shouldn't it work? Why is it that it won't work?
    If I get Verbatim DVD+R DL, can I burn at 8x speed with those?
    When I burn in disk utility I used the "varify burned data" and everything checks out ok. So why do I have this issue. Just curious.

  • Video playback issue with 3rd gen iPod Touch

    Hi all,
    I just recently discovered an issue with my iPod touch 3rd generation video playback. The issue just reared its head today and I have no idea what I could've done to cause it. It's a small issue but frustrating enough to cause a problem.
    If I watch a video normally (by opening up the Videos section and picking it), it'll play through to the end, then start over again, then stop. This only happens if I choose videos randomly, and doesn't happen if I play videos in a playlist.
    What could be the issue?

    I'll second that. I've been having the same problem since the last software update
