Red Hat / Fedora :: Audio Stuttering In Flash Video Stream
Feb 17, 2011
i've been experiencing an issue with audio playback for certain flash videos that stream from the web. most play smoothly, like the videos at videos. others have this strange background noise that is only present when there is audio (usually on news websites that host their own videos). when there is sound, there is a strange stuttering noise that disappears during the silent pauses.
here's a perfect example:
epidemic of tsa criminality: more agents caught stealing cash from luggage, another arrested for assault. the videos video at the top plays just fine. if you scroll down and watch the other video in the small box, you'll hear the stuttering. i have fedora 14 kde, adobe flash player 64 bit preview release 3 and rpm fusion codecs installed. the problem is also present in fedora 14 with gnome, same setup. the problematic videos play without the stuttering in ubuntu.

Since updating to 10.10, randomly sometimes the CPU usage will just up (although it's generally only 1 of the cores), it seems that it might be the Xorg process using it.
Audio and Video will start to stutter and the screen will stop updating so things like the terminal will appear frozen unless the mouse is moved.
When moving the mouse the screen keeps updating and the cpu usage lowers (although video still skips).
After a few minutes the problem just seems to go away until it happens again later.

I've been having a problem with intermittent stuttering in video and audio playback since upgrading to Maverick (it also happened when I briefly installed Lucid). It started out as the odd skip every 20 minutes or so but now it can happen 5 or 6 times in 10 minutes when watching a film. I've tried:
reformatting and clean installing using a half-dozen players installing every codec I could think of (only after the normal ones wouldn't help) diangosing my 3 hard drives (the problem occurs on them all and they're not in a RAID setup) changing then changing back my video drivers disabling pulseaudio and ubuntuone-sync (these were not installed in my previous, working setup) looking at every relevant log file (mplayer, smplayer, demsg...) I know of running ubuntu's testing utilities I'm out of ideas. Going back to Jaunty is the only solution I'm pretty sure will work but it's not exactly ideal. It will be a few months a least before I'm able to install a completely new distro.

I just installed firefox's flash plugin successfully and I can see it in the About:Plugins and it is enabled. But if I go to ..... to stream a video, I just get a black screen instead of the chosen video.

I recently installed Fedora 12 on a new gigabyte mb and for unknown reasons to me videos from ..... and others run very fast (5X) or more, and I'm also unable to get audio to work. All this only happens if I'm using KDE, all work ok in GNOME.

I am looking at ripping the audio from a very old episode of 'In Our Time'. The episode is so old that it predates the podcast (which of course, would solve all my problems). I would like to use something like icecream or VLC to rip the audio from the 'Listen Now' link on this page. Unfortunately I am having a hard time finding the actual URL. The player itself is a Flash widget, so it is something more complicated than looking for OGG, mp3 or RAM file extensions in the page source. If there are some nifty command flags I should add when invoking icecream on the command line, I am all ears.

We have a Jetway JBC600C99-52W-B (Mini-top) with Xubuntu 10.10 and Logitech Z-205 USB Speakers but I have no sound. EDIT: fixed after installing gnome-volume-control and selecting my output device. Now i have a other problem, when i stream a video it plays sound for 1 second and when i click the play button it works fine for a while but after a few minutes the audio stops again. the video plays fine.

Does this meet the required 4 ports mentioned for alike cameras in the forum posting. If not, I have one of these.. Is this what they are talking about. I have just started thinking about this again and am not sure if I'm asking the right question. I don't want to go buying a bunch of hardware I can not use. So I'm hoping to look to someone here who has some experience in live streaming audio / video to one of the distribution sites.

I've just made the move to openSUSE* and after the installer seemed to bork my xorg.conf because of my Wacom tablet things have been going quite smoothly. My only problem at the moment is that MP3 playback through Exaile, Banshee or Totem stutters and pauses several times per track or more. The only commonality I can see is GStreamer, but nothing is giving me errors to the console.
Code:
rpm --query --queryformat '%{NAME}-%{VERSION}-%{RELEASE}-%{ARCH} -> %{VENDOR}
' gstreamer-0_10-ffmpeg gstreamer-0_10-fluendo-mp3 gstreamer-0_10-fluendo-mpegdemux gstreamer-0_10-fluendo-mpegmux gstreamer-0_10-plugins-bad gstreamer-0_10-plugins-base gstreamer-0_10-plugins-good gstreamer-0_10-plugins-good-extra gstreamer-0_10-plugins-ugly

* I ditched Fedora to get better Monodevelop support after using Redhat 7.3 and 9 followed by FC 3 and 6 then Fedora 7, 8, 9 and 10. The Ubuntu forums seemed to keep giving me occasional answers to questions, but the Suse build service gave me the RPMs, when the requirements matched.

I'm not sure what's causing it, but when I play or pause a flash video in Firefox or Chromium, there's about a second of audio delay.

I watch alot of news videos and within 1 - 2 minutes the video and audio become out of sync. The video is lagging the audio. I'm using 10.10 32 bit with Shock Flash 10.1 r102 on Firefox. Will the 10.2 beta flash fix this problem?

I am using Firefox 5.0 with Ubuntu Lucid x64 and I have no audio with Flash video. Audio works just fine on other applications so I'm guessing this might be a permission's issue or setting of some sort? I also have: flashplugin-installer 11.0.1.60~110713-ppa0~lucid & flashplugin-nonfree 11.0.1.60~110713-ppa0~lucid installed with ALSA v1.0.24.2.

Watching the BBC iPlayer bigscreen (URL>..) in Firefox 3.5 with full screen plays smoothly. But any other combination for example...iPlayer on Opera 10 or Channel 4 Ondemand (4oD) in Firefox then the flash video playback is very stuttering, horizontal tears, just one still image per second, etc.I want to investigate the reasons for the poor playback but where do I start ? cant be hardware because FF is ok at least for iPlayer.
Maybe 4oD has some different encoding of video compared with BBC but how can I tell what the encoding is? How come Opera using the same flash shared object has difficulty but not FF? (I've raised a bug with Opera a few months ago but no joy so far)

I switched from XP to Ubuntu a few days ago and I'm having a hard time getting flash to work properly in firefox. I can play videos and music in a non-flash format just fine, but flash videos play without sound and really choppily.

This happens nearly anytime I watch any relatively lengthy flash video on ..... or other online flash players. I watch the video, and the audio is fine for a few seconds, but then the audio cuts off as the video continues to play. Sometimes, when I move the scrollbar of the screen/pause and replay the movie, it starts back up again for a few seconds then shuts off or plays the audio I just heard.

VLC says: "main input error: ES_OUT_SET_(GROUP_)PCR is called too late" when I am playing back most Bluray discs I have tried.
See this bug post for what I am talking about: [URL].... It has to do with playing back h264 video with ALSA.
Possible fixes:
1. Obtain VLC 2.2.2 - see below
2. Fix by Modax here: https://trac.videolan.org/vlc/ticket/10422 - not currently using dmix and not sure how this will relate to HDMI sound
3. Use Pulseaudio - this does not work for me to get HDMI sound and I do not use Pulseaudio as a rule
I have just tried to compile VLC 2.2.2 and the configure script finished properly but early in the build it fails.
With make the error is:
Code: Select alljason@MEDIA:~/vlc-2.2.2$ make -j4
make all-recursive
make[1]: Entering directory '/home/jason/vlc-2.2.2'
Making all in compat
make[2]: Entering directory '/home/jason/vlc-2.2.2/compat'
GEN dummy.c
make all-am
[Code] ....
And with compile the error is:
Code: Select allMAKE : compat
MAKE : doc
MAKE : po
MAKE : share

I have tried installing 3 different versions of libua-dev, 5.1, 5.2 and 5.3. What could be the problem?
With the bugged audio drivers I'm going to replace the computer but it would still be nice to be able to know the solution to compiling VLC 2.2.2.

n an up-to-date kubuntu karmic I experience the following:watching a flash video with adobeflash in firefox in fullscreen mode, randomly the picture freezes while the audio continues. The video unfreezes when I move the mouse, the video then fastforwards to the actual replay position. Video card is nvidia geforce fx5200 on proprietary driver, I have the desktop effects enabled. Any idea what this is about? I discovered the effects causing wine windows to break (no window contents, no foreground, no reaction on mouse) when changing the desktops or minimizing them. Seems like there are some bugs in the window manager / decorator...

I'm seeing regular stuttering in PAL video when running at the default 1920x1080 50Hz but not apparent when I use nvidia-settings to switch output to 60Hz. It's most noticeable when the video pans and you can see the video stutter ever half second or so.

Nvidia driver 195.36.24-0ubuntu1~10.04

I am fed up of listening to my (Windows XP) gaming computer through headphones so I want to get it hooked to the stereo.
Rather than use a heck of a lot of wire, I can sit my Ubuntu 9.10 netbook on top of the stereo and stream the audio across WiFi.
So, ideally what I am after is something to capture the outgoing audio on the Windows computer, stream it across the wifi to the Ubuntu netbook and finally play it through the speakers.

I am working in Fedora FC11 with: Mozilla/5.0 (X11; U; Linux i686; nl; rv:1.9.1.5) Gecko/20091105 Fedora/3.5.5-1.fc11 Firefox/3.5.5
In the following site I cannot see the video stream:[URL]...Choosing "TW1 Livestream" should gives a video stream, but it gives a black screen. Clicking on that black windows gives a text: Waiting for video.
A German text shows that the actual Version from Windows Media Players should be installed.In the past I could see video there, but after an upgrade it does not work any more.Looking in aboutlugins I see following Windows Media Player plugins:

I'm trying to diagnose a weird problem ... maybe someone has an idea where to start. I'm having a problem with flash videos. The video part displays as if the fast-forward button is being held down; audio sounds correct.
I'm thinking "synchronization error" (duh!) but I'm not sure how to start to diagnose the issue. I'm running OpenSUSE 11.4 x64, and the problem shows up in both chrome and opera.

I just came home from a long trip, with a lot of videos shot during the holiday. I wish to share them with the rest of the family and friends, but the files are huge (full HD). I intend to upload them to the family server, so ..... and the likes are not something I want.

To get multimedia working, or explain what I'm doing wrong.
The problem is that none of the video players doesn't play video, they show only black window and play audio.
I have Fedora 11 Leonidas, fully up-to-date.
I have installed rpmfusion and livna repository.
I have installed following packages:
When I try to play video with totem, it doesn't output any error, but just doesn't play video.
with mplayer:
xine and kaffeine just say:
vlc:
I tried several different files, which works perfectly in windows and ubuntu.
I installed windows binary codecs for mplayer to /usr/lib/codec/

We have remote offices and we'd like all announcements in one office to stream to the other offices, to play on the speakers connected to VLC machines there. We can stream audio with VLC when working with a file, but how would we stream all audio produced by a single machine?
Ideally this would stream anything coming in from AUX/Line-In jack, as well as any other sound that the computer would make. I'd prefer to use cvlc (CLI version) rather than the GUI VLC, but whatever I can get would be good.We can run either Debian 5.0.x Lenny with 0.8.6.h-4+lenny2, or Debian 6.0.x Squeeze with 1.1.3-1squeeze2

This plays fine in VLC, and there's a "Record" button there but I'm never prompted to save the recording anywhere. I wandered through preferences but didn't see any default capture directory fields.Where/how do I capture the stream for playback later? The docs that I've stumbled across so far are pretty outdated (but I'm still googling).
