Ubuntu :: Extract The Audio From The PDF ?
Jan 20, 2011
For about three months I've been going up and down the internet looking for a solution to this problem... Basically I take this distance learning course. Every lesson is sent to me via email in PDF format and it includes many audio examples which are embedded in the file. The problem is none of the Ubuntu readers seem to recognize it, and the Adobe reader says I need a plug-in which does not exist for my system. I quote: "We're sorry, but the third-party media player required to play the selected media file in your Adobe PDF document isn't available for your system". I've been taking this course for two years and I still have two more to go. I contacted the company that sells this course and they were as puzzled as I am... Is there a way to extract the audio from the PDF? Or alternatively open it with another application? I would hate to have to go back to windows for this one issue...

I'm trying to extract audio and then convert to mp4 format a bunch of flv files downloaded from internet. There are three files I intend to use ffmpeg in the following options:
ffmpeg -i input.flv -acodec copy output.mp3
and
ffmpeg -i "input.flv" -f mp4 -vcodec libxvid -s 640x360 -b 768kb -r 25 -aspect 16:9 -acodec libfaac -ab 96kb -ar 44100 -ac 2 "output.mp4"
So I started writing a script like this:
#!/bin/bash -x
cd /home/koli/exp
[Code]....

If I convert an audio file to a different format (such as mp3) using a pipe I lose the tags.
Code:
ffmpeg -i <filename> -f wav - | lame - output.mp3
If I knew the tags of the input file I could put them back using a program such as id3v2
[code]....

I have two video files (Xvid) and would like to combine the video from one of these with the audio track of the other, in order to create a new video file.
This is somewhat complicated by the fact that I would like the resulting audio to be a mixture of the two original audio tracks, for instance, during some time segments, I would like to switch from one to the other, but the video should always be the same.
Another issue that complicates the things is that the two audio tracks have different bit rates, and when I briefly managed to merge the two, one of the audio tracks was playing much faster than the other. To clarify, the audio tracks should not overlap but just be played at the different time during the video playback.
I am trying to do this by using Audacity. The problem is that I am fairly new to Audacity and I have not been able to find any info in their user guides regarding this specific issue.

I've decided to start backing up my dvd collection. I want to extract all of the audio, video, and subtitle streams individually (from the main movie title only). Then for convenience and usability I want to put them all in a .mkv container. How can I do this and with which programs? ffmpeg, vlc, mplayer? If I can do this all at once, that's fine. But I don't want to get the streams out of sync.

I want to listen to this audio file: [URL] but my real player 11.0.0.4028 gold desn play it, it says that there is a codec 28_8 missing, I go to relaplayer page, download the last release available for linux systems, but the message is the same : audio codec missing and doesn't play the audio.
I havev tried to play the audio with smplayer (not luck), vlc can play the audio but the pause button doesn't work so I have to listen the entire audio all the time I stop it playing. Is there any audio player capable od reproducing in the proper way this audio in ubuntu? No one of my video players totem, smplayer, realplayer or vlc are capable of playing this video: [URL]

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 have behringer UCA202 usb card, after plug to usb, it just works , I have only small problem with alsamixer, which still shows by default my integrated HDA Intel, I could switch it by F6 or by alsamixer -c 1no problem, but I expect that default card is now plugged "USB audio", so why alsamixer recognize default audio device as HDA intel and not a USB Audio ?anyone who has two or more sound cards with the same issue ?

I'm thinking of installing openSUSE-11.1 Gnome on a Fujitsu-Siemens Amilo 7400M laptop because the wireless in Gnome is much more user friendly than KDE3/KDE4 in openSUSE-11.1. The idea is to give this laptop to my 84-year old mother and things need to 'just work' for her (she currently has a desktop running openSUSE-11.1 KDE3 that uses a WIRED interface to the web).
I refuse to update this laptop to openSUSE-11.2 nor 11.3 (nor other recent distributions) because every kernel update after the 2.6.27 kernel has broken the Intel i855GM graphics drivers for that laptop. There are many bug reports and none have fixed the problem for this Fujitsu-Siemens implementation of the i855GM graphics.
Hence I am looking at Gnome.
I booted the laptop to a Gnome openSUSE-11.1 liveCD and wireless is easy and works great. But audio is very very VERY bad. It is incredibly user unfriendly and it does NOT work well. I assume that is because pulse audio in openSUSE-11.1 was very immature.
I note these updated packages in the openSUSE-11.1 update repository:
Code:
So my question is, did the updates to pulse audio (in the openSUSE-11.1 update repository) fix the pulse audio situation? Are there ANY helpful views on this?
Currently my wife is using this laptop with KDE-4.4.4 (and openSUSE-11.1) so I can't just install Gnome and play with it without taking the laptop away from her for a while (note the hard drive is too small for a dual boot of KDE/Gnome).

I have been using windows operating system for a long time now, but I am not well familiar with linux. Whenever I used to install Windows, I used to install the corresponding audio drivers(in order to listen to the music). The problem I am facing is that I do not know how to install the audio drivers(if they really exist in linux Mint 10 operating system). As a result I am not able to listen to any audio file due to lack of corresponding audio driver programs. make proper configurations settings so that I can listen to audio files in Linux Mint version 10.

I am having trouble getting the pulse audio server to find the hw0 with the common m-audio 24/96 audiophile. This card worked with previous versions of all forms of pulse but seems to bork on the HW0 function for audio out...which is a stereo analogue simple output. Audacity sees the HW functions but pulse does not! Here is a screen shot of the pulse crap. And another screen shot of what the real card at "alsamixer -c 0" sees. There is no dac or adc detected or configured with pulse. This does not make any sense as alsa and alsamixer has all the correct device controls available to any other software that uses the ice1712 driver.
I am using Fedora 12 amd 64 as a live usb on a 16 gig stick and want to be able to record and mix audio on to HD with my reliable high end m-audio pci sound card without having to mess with the pulse crap or having to install a full HD option. BTW in the pulse sound configuration gui dropdown list there is no indication of HW0 and the only devices that are available in pulse are digital outs.....go figure, so essentially I can see all the correct connections and use programs that access alsa directly eg: audacity but have no sound through the crappy and ever borked pulse audio server! Any suggestions as to how to remove all the pulse stuff that comes with most distros that use gnome? I have done this deed before with Ubuntu but do no know how to do the deed with an rpm based system. If I install a non pulse version of xmms and let it use jackd then I should have reliable sound for cd audio etc and should be able to configure VLC, Ardour and Nted well without pulse getting in on the action and screwing up my sound.

to start off, i'll post the specs of the machine:
dell inspiron e1505
3.2 gb ram
1.86 ghz intel core duo
ati x1400 gfx
opensuse 11.4 kde 32 bit.
okay, here are the details: can't play any audio with amarok when desktop effects are enabled because the minute a window is moved, it will distort the audio. even when disabling desktop effects, some applications still cause this. can't play videos videos even with desktop effects disabled because of the same reason.
i just switched from ubuntu and when i ran version 11.04, i had to disable kms to do anything. i tried on opensuse 11.4 and the audio was flawless but the gfx went all to hell.

I am having some issues with getting Ubuntu Studio 10.04 to work correctly on my system. Everything works fine except sound. I have a M-Audio Delta 66 audio interface and my onboard sound is disabled. When I run the command alsaconf I can see the ICE1712 card without issue. However when I run alsamixer the only option it is giving me is my HD sound from my ATI video card. For some reason it seems the ATI card has locked the audio to it with no way to remove it. I have reinstalled the alsa drivers for my card and can only see it through alsaconf. When I tell alsaconf to configure the ICE1712 card it says it configured it properly.When I run the command envy24control it says no ICE1712 cards were found.

Is there an application that anyone knows about that I can use to convert either an .flv or .ogg file that contains both audio and video to just an audio .ogg file (preferably vorbis+theora) without audacity? I'm fairly certain audacity could accomplish this but it seems like overkill for what I'm trying to do and the computer I'm trying to use does not run it so well.
::EDIT:: I should also mention that I've tried looking on google. I did find downloadhelper extension for firefox which uses ffmpeg to convert the files but I don't see any obvious way to strip the video.

on my PC I have 2 sound drivers, one from the mainboard (AC97) and one PCI card (ES1969). Because the mainboard sound path did not recording, I installed the PCI sound card and with 11.1, I managed it to play and record all audio data. With 11.2 the PCI sound path plays the system sounds (suse start-up or shut-down sounds) but not the streaming audio data (skype, flash player). But these are played by the mainboard audio instead. The audio-tests from yast->hardware->sound work for both paths. How should I configure the system to redirect the audio streams to the desired (PCI) audio path? The PCI audio is set as primary sound card and is not muted.

Say I have 2 speakers connected to 2 different sound cards. Under Windows, is it possible to have some sort of virtual device that would forward an audio stream to both sound cards? If this can't be easily done under Windows, a solution for Linux is also fine. lternatively, if the 2 speakers are connected to different channels of a sound card, is there any vendor-independent way to duplicate audio to both channels?

The workstation is running FC14.
I have the audio out of the media machine passed into the line in on my workstation. It's just handly to have the audio pass in this way so that i can manage the volume or headphones or whatever from one machine.
This worked, and worked well, for a very long time. I recently reinstalled the workstion, FC14 still. After the reinstall, my passthrough doesn't work.
If i start up some media on the media machine, and then open up the volume control on the workstation, i can see the volume meter moving along with the audio, but nothing plays out of my speakers.

i have opensuse 11.3 (64-bit) installed. kde version. my sound card is a creative labs sound blaster x-fi xtreme audio, pcie interface. i am able to listen to cd music without any problems but i am unable to get streaming audio when i visit any internet radio site, videos, yahoo!tv, etc. etc. for instance, when i visit videos, the video part is ok but i cannot hear anything through the speakers. something similar happens when for instance i go to [url] and select any of the music channels. a new window pops up but the music never even starts to stream.
i know for a fact that both sound card and speakers work fine because i've tested them with windows xp. so there must be some setting in opensuse that i've missed. the weird part is that i can listen to music cds without any problems...

I've been trying to download DJL for a while now and I keep getting error messages. I've been looking at instructions on how to do it and I do what they say. I download it and then I extract it. I think I'm getting confused on where I need to extract it to. I'm very new to this and I'm trying to learn. I've been extracting it to my desktop... then I enter into the terminal sh djl.sh and it gives me sh: Can't open djl.sh. I have the newest version of Ubuntu.
