Ubuntu :: Avidemux Running Audio Too Fast After Encoding?
Jul 18, 2011
I'm using using ubuntu 11.04, and im using Avidemux (GTK+) whatever date that is, got it a couple days ago from the software center.
I attached some .a/s/s subtitles to the video, and the preview looked great. Encoded the video, and the audio plays like two times faster than the actual video, so by about halfway through the video, the audio is done and im left in silence with the video still going.
I set the video to MPEG-4 AVC, attach .a/s/s subs, leave audio alone, and encode using default option (Single pass-quality quantisizer)

under avidemux-qt, the videos play and encode w/out any audio output, and audiodevice is set to "dummy" and cannot be changed. but avidemux-gtk has no problem w/ audio playback.Is this an application specific problem, and if not how do i configure phonon to fix this issue?

First and foremost is Avidemux. Somewhere between Fedora 11, 12 and 13 Avidemux lost the capability to encode audio streams in AAC format. I've installed all pertinent packages for it and for AAC, and even though AAC is available to other programs (Banshee, SoundJuicer, etc), alas it is not in Avidemux. I read somewhere that since the newer version of Avidemux now uses a plug-in architecture, support for a lot of formats might be missing as they get ported.
I use Avidemux as usually I rip my DVDs into .mp4 files which I serve up from a Linux box at home and stream them to my PS3, or simply to load a bunch onto my laptop to watch on the move or when I'm on call at the hospital (like I am right now)...
Kind of related to this that I remember not too long ago, I was able to convert a DVD into PSP's mp4 format from DVD::Rip, IIRC directly from the application, but last time I used it, it only seems to have support for AVI, OGM and MPEG container formats. Maybe somthing changed along the way that I'm not aware of.
It looks to boil down to the fact that the package avidemux-plugins from RPMFusion is missing the necessary plugin... I'll go check why is that.

I have been using Avidemux to encode edited video using x264 and the mp4 container for most of my videos. My PCs are not new, using single-core AMD Athlon processors.
In 9.04 and 9.10 (Linux Mint), encoding speeds ranged from 7 to 10 frames per second. In 10.04 these dropped down to less than 2 frames per second.
I booted back into Linux Mint 8 (9.10) and the same video encoded at the previous 7 to 10 fps.
I tried with other videos in different formats (mpeg2 and VOB). The results were the same - 10.04 was extremely slow encoding x264 but Mint 8 was "normal" at 7 to 10 fps.
With a dual-core notebook, however, the encoding speeds ran at 8 to 14 fps in 10.04.
Was 10.04 optimized for dual and multi-core at the expense of single-core? If so, is there a way to restore "single-core optimization"?

I Updated from Fedora 9 to Fedora 13 several months ago and noticed that AAC audio encoder was no more available in Avidemux (I use version 2.5.3.3 for fedora 13 from rpmfusion repo)Unfortunately AAC is mandatory on the IPod (and probably other Apple devices) to have the sound working.I had faad2-libs (decoder) and faac (encoder) packages installed, but avidemux was not using them.After some search on the web, I found that faac support was removed because of legal issues.Some people recommend to rebuild Avidemux from source but this was a little bit complicated, and I found an easier solution.
In fact the only thing needed to add AAC support to Avidemux is to add the required libADM_ae_faac.so library in /usr/lib/ADM_plugins/audioEncoders, as it is no more supplied in the package avidemux-plugins. Searching for libADM_ae_faac.so on the Web, I found some packages containing this file, such as the ones from other distros, and the package for the same Avidemux version than the one I use but for Fedora 11 : avidemux-plugins-2.5.3-3.fc11.i586.rpm.

I'm trying to encode a wmv file to flv with ffmpeg. The video codec is WMV3 and the audio codec is wmap (Windows Media Audio Professional). The command I use is:
Code:
/usr/bin/ffmpeg -i <input file>.wmv -s 640x350 -b 1024k -r 25 -ar 44100 -ac 2 -y <output file>.flv
Output:
Code:
FFmpeg version 0.5-svn17737+3:0.svn20090303-1ubuntu6, Copyright (c) 2000-2009 Fabrice Bellard, et al.
configuration: --enable-gpl --enable-postproc --enable-swscale --enable-x11grab --extra-version=svn17737+3:0.svn20090303-1ubuntu6 --prefix=/usr --enable-avfilter --enable-avfilter-lavf --enable-libgsm --enable-libschroedinger --enable-libspeex --enable-libtheora --enable-libvorbis --enable-pthreads --disable-stripping --disable-vhook --enable-libdc1394 --enable-shared --disable-static .....
Stream mapping:
Stream #0.0 -> #0.0
Stream #0.1 -> #0.1
[wmv3 @ 0xb32c00]Extra data: 8 bits left, value: 0
Unsupported codec (id=86056) for input stream #0.1
As you can probably see the audio codec is not supported. Is there a way to encode WMV3+wmap with ffmpeg or any other tool in Linux? Windows Media Encoder in Windows is able to encode such files to a supported codec. For example: WMV3+WMA2/WMV2+WMA2, I could then encode it in Linux. I'm trying to find a way to directly encode WMV3+wmap in Linux.

My install of 10.10 went fine with the exception of Audio. If I attempt to use audio with the Rythmbox application or through Adobe Flash (in firefox), it sounds like an old fashioned 33 1/3 rpm phonograph record playing at 45 rpms. This problem has been around for a while and I had hoped that it would be cleaned up by now.
I'm running an AMD 64 processor (in 32 bit mode) and my audio card is a "Sound Blaster Live Value" (EMU10k1X). My on-board sound card is turned off in the bios. It works beautifully under Ubuntu 10.04 and FC13 with Pulse Audio.
Originally I thought that it might be a problem with Rythmbox which is now at v 0.13.1, a later version then I have been using in 10.04. However, with the Rhythmbox application off, I still get the same effect when trying to use audio in firefox. I also noticed that my cpu utilization climbs to about 80% when Rhythmbox is on.

I've installed Ubuntu 10.04 and it works like a charm, pretty much all over. However I seem to have problems using my M-Audio Fast Track Pro with all four channels - primarily when using Mixxx. I hate to switch between Win7 and Ubuntu just for the use of my VCI-100. Is there a way to have Fast Track Pro work? I tried almost any of the solutions found around here - but i simply cannot get it to work.

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'm in trouble with playbacks (video and audio, desktop apps and live streams on Firefox). They are all running at least at double speed.
[URL]
Running Fedora 13 - 64 bits - cpu AMD Phenom II X2 955 (dual core) flat, no overclocking, no hacking of any kind. I've tried a re-install of all media codecs and plugins. The problem persists since fresh install of Fedora.

Just did a fresh install of Karmic, got all necessary decoders installed for video and audio playback...I think.
Problem is I can't forward/search in audio files I am playing. I mean I can only Play, Pause, Stop or "Next-track" a music file. Video files are fine.
I've tried Exaile, Rythmbox and even Totem. It is like the audio files are "half read-only".
If I drag a horizontal scroller in the music player and let it go, it will only jump back to the position where it is actually playing.
Has anyone experienced, this? I am a missing something in gstreamer or something like it?

I have a Dell OptiPlex GX1 (CPU: Pentium II, 500Mhz). It's very old, and a while ago I installed an old version of Ubuntu on it. While it is switched on and booted up, everything is fine, however the trouble is when it is switched off, or just in BIOS.
The BIOS clock appears to be running at about 60x speed (eg minutes like seconds, hours like minutes). This happens both when switched off and when observing the clock from the BIOS menu. I really don't know what to do about this, and it's causing alot of problems, I've even had it get to the point where the system clock reset itself and would not recognise the OS as valid.

I am using AT91SAM9260 and running Linux 2.6.27 on it. Once i sync the Kernel clock and cmos clock with the reference clock and leave it for 1 day, i see a drift of nearly 8-10 sec. The kernel clock is running faster. How can i correct this?

Before the other day, I'd copied a live CD to ramdisk and run it from there before, but the disk was INX (INX is not X), a live CD based on Ubuntu that runs entirely in the text mode, no GUI. INX is a terrific product: colorful, educational, light, agile, fun to use, and and often damned useful, but when an OS only uses text, you may not notice how much running from the RAM speeds up an OS. Previously, I'd assumed that the best reason to run a Live CD from the RAM was to free up the CD ROM drive. When I started running a full KDE 3.5.10 Desktop from the RAM, it didn't take me long to notice the awesome boost in speed and performance.
The computer has the fastest access to the data that's in the RAM. (The "A" in "RAM" stands for "access", right?) So the machine is faster. As the RAM gets larger, I'm sure more and more live CDs are going to offer the RAMdisk option. Right now both INX and SLAX share the characteristic of being exceptionally small CDs, and that makes them well suited for this kind of application. The "minimal" version of Slax, the basic CD without any modules added, is less than 200 mbs, which fits very nicely on my 1024MB RAM. I now use the minimal SLAX cd to initiate the system, and I keep a collection of the modules on my hard drive to copy to the RAM and activate at will.
Here's a couple of screenshots: [URL] I'm using Wine here to run my one and only favorite Windows program, a text to speech program called READ PLEASE. Note that I am also running KTorrent, which is uploading from and downloading to my external MyBook hard drive. [URL]. Here's a shot of yakuake, which is sort of like Konsole with superpowers. I just upgraded my hard drive KDE system to 4.2.3, and they still haven't fixed Yakuake yet. I know it's been reported, so I'm sure it'll be taken care of.

I'm running Kubuntu 9.10, and I like it (yay!) But I've been having issues with sound. Especially under system load I've been having an error where it says that the device analog 9xxx has failed falling back to digital, then it says almost immediately device digital 9xxx has failed falling back to analog. At this point any programs playing sound seem to retain that ability as long as I don't close them, but any programs I open have no sound. This applies to webpages and flash, as well as internal programs. I have also been having issues with video, no errors, but the video skips and freezes. Flash video occasionally crashes and any flash games that submit data (e.g. high scores) to a remote system crash my browser.
I end up having to pause the video and move it back several frames, then wait as if it had to load from ..... for a while, and it will run again for some time. My hardware is a dell inspiron e1505 on which the only things I have done are to replace a broken monitor and upgrade the ram (that is, after I broke windows too many times and converted to Linux. I don't have more error data for you, I simply haven't had the foresight to stick it into a text file yet. The error is displayed in the Notifications and Jobs button in the system tray, which is not well suited to copying and pasting, and I'm admittedly unsure as to how to find the error. I learned BASH on Sun unix at my local college and I still haven't quite learned all of how to speak ubuntu's terminal.

I have Songbird running on another display on the same machine as my Mythtv frontend but while the frontend is running, audio seems to be disabled for it and other applications. I assume that this is because Mythtv suspends Pulse audio.
Is it possible to make this work without enabling pulse audio?

I've had this problem in the past, but it's more frequent for me now. Running Ubuntu Karmic (9.10), and if my browser is open long enough the audio in flash dies until I restart my browser. I'm running Chromium (non-google branded). I'm fairly certain this is happening in Firefox too.

I'll try to make this short, esp because I don't know if this is the right place to discuss a 3rd party program like "Avidemux" I'm running the latest version "2.5.4" or so. It started giving me this problem where no matter what settings I give it, the resulting files are so small it results in an error after almost a day of encoding. ( "XYZ" was NOT saved correctly , for example.) One day I noticed the quantisizer was at max, peaking at 48-50...which made the files tiny. So, I can avoid this sort of, by limiting the maximum and minimum quantisizer in the configurations. Problem is, I have no control over target size or bitrate this way..and sometimes the results are still unplayable.
Naturally I've uninstalled and re-installed several times, and recompiled the x264 codecs using this guide: [URL]... So, I downloaded the Tar.gz of the previous version i was using (Avidemux 2.5.3), the last known thing I know that worked for me...but I have no idea how to install it. I've tried running "Make" / "Cmake" In which I was told that an "in-tree-build" was detected. And trying to run the included "bootStrap.sh" results in : "Permission denied" or file/command not found. I don't think their old releases come in the default Ubuntu/Unix package "deb" right?
All these could be small errors on my end, but It urks me. In between reading up, and everything else that needs to be done in a day, I could have been done by now... Does anyone know where i could be going wrong?

Installing 11.2 from KDE LiveCD on an IBM ThinkCenter with 3.2Gb CPU and 1Gb RAM. Ubuntu 9.04 on first two partitions. I go through the configuration, click to 'install': Install display bars remain blank. After 2-3 minutes, black screen with scroll of attempted installation pieces and the error message: "Respawning too fast. Disabled for 5 min." Freeze.
Other posts mention problem with init. But this is happening with the install so not able to address that. No apparent md5chksum for LiveCDs. No mention of this problem in installation help guide. Does anyone know how to deal with this? If you need more info, I will provide. Though it seems this is not an unusual problem when booting an installed system, there's no mention of it happening during installation.

Since upgrading from 10.04 to 10.10 (through the update manager) my previously well working avidemux now will not even start. here is the output from the terminal.
Code:
*************************
Avidemux v2.5.2
*************************
http://www.avidemux.org
Code : Mean, JSC, Gruntster
GFX : Nestor Di , nestordi@augcyl.org
[Code].....
I have unistalled and reinstalled avidemux with the same results. I have also uninstalled the ffmpeg, mencoder, and medibuntu codecs and reinstalled, however, I am getting the same terminal output and the same results.

I eventually did buy a Terra HD from Zareason that I love, but I cannot get it to do my video editing of Flip Mino home videos. I know the machine is capable. It plays bigger AVI files without any problem. For sound it uses the Realtek chipset. Samples of the .avi Flip Mino videos are here. A nice short one for experimenting with is 2.3 MB, here. According to Avidemux, the Flip Mino videos have the following video properties...
Codec 4CC: XVID
Image Size: 640 x 480
Aspect Ratio: 1:1 (1:1)
Frame Rate: 30.000 fps
and the following audio properties...
Codec: MSADPCM
Channels: Mono
Bitrate: 22179 Bps / 177 kbps
Variable Bitrate: No
Frequency: 44100 Hz
My goal is simply to trim the beginning and end to get the best segment in each home movie. Avidemux worked great on my old machine as long as I changed the output audio format to MP3(LAME). But Avidemux is not working and wants to know all sorts of things about devices of which I am ignorant. The default settings must be wrong since the audio playback is choppy and usually the video saves to a one-frame broken file.
I also tried Openshot and it has no device preference issues. However, I am ignorant of how to make it save the videos properly. It wants to "export" the video using all sorts of options, none of which are simply "use the setting for the only track". Based on the 640x480 size I tried some Square NTSC tests but the exported file was always much too big -- usually larger than the untrimmed original!
Also, Openshot appears to lack a keyboard shortcut or button for "move the beginning or end of the clip back or forwards one frame". Is it really expecting me to use the mouse to position the clip's borders precisely? I have no vested interest in which software is used. Nor do I care about the resulting file format as long as it is neither wastefully large nor senselessly abandoning quality. I just want to share my home movies with friends and family.

I installed avidemux so I can split a video file. However avidemux doesn't show up on the menu. It should appear in Applications->Sound and Video but it's not showing up under any of the menu items. When I go to Ubuntu Software Centre it shows that avidemux is installed. How do I find it so I can run it? I'm running Karmic.
