Ubuntu Multimedia :: Extract And Joing Multiple Audio Tracks With Video
Dec 2, 2010
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'm trying to get Totem to play VCD's. There are many complaints about this not working, but since they're all really old and dealing with different problems, it's hard to tell if this is an issue with me, or with the totem package. When I put a VCD in the computer, I expect it to pop up, (as it does) and prompt me to open the CD with Totem (which it does). When Totem tries to play it, though, it throws this error:
Code: An error occurred. Could not open location; you might not have permission to open the file.
Interestingly this is the same error I get when I try to play DVDs on a separate computer with the same ubuntu software. The CD plays, however. If I click ok, and go to:
Movie > Play Disk '<disk name>'
The problem is:
1) I want it to be automatic, without errors,
2) These VCD's have several tracks and after the first 30 second track, it stops. It won't play any other tracks.
I tried a few other pieces of software just to see if other things worked (as I'm looking for user friendly-ness, I doubt the others will be a final option):
VLC: (No apparent activity. Disk spins)
gxine: Autoplay input plugin 'VCD' failed: Check engine output for further details.
Mplayer: Error!: Failed to open vcd://2.
K3b seems to have no problem, but it's not really a media player...

I am trying to rip my "Queen's Greatest Hits I" CD to my hard drive as FLAC files. For the most part, it's going well. But let's say I want to rip Track 16 (We Will Rock You) and Track 17 (We Are The Champions) as one track. (Because really, who ever listens to those tracks separately???)
What is the best CD ripper software to use to accomplish this? So far I've tried Asunder & Audex, but I don't want to download every ripper before I find one that will let me do this easily.
I was able to do what I wanted in cdparanoia at the shell:
Code:
cdparanoia 16-17 Queen_We_Will_Rock_You_We_Are_The_Champions.wav
But then I lose all the convenience of automatic tagging, etc.

My question would be this: is it possible to open different audio file tracks into the same piano roll, or even open multiple piano roll instances at the same time? If the answer is "no", then does anyone know a good LADSPA sampler plugin? Basically, I need to be able to load multiple samples into the same instrument and have them set to a range on the keyboard, similar to what the advanced sampler in Reason does.
Having multiple samples in the beat editor is not the same, as I need to control the note off (without re-loading the sample and just changing the end time, that is too cumbersome). If any of this seems weird I should specify that I am making breakcore music where drum beat samples are highly manipulated and a piano roll for each sample is just going to be too annoying to program.

I've been googling this problem a lot these last couple of days, with no luck.The thing is, I need to record audio from an old Tascam four track cassette recorder. I have three tracks on the tape and I want to record them to three seperate tracks on the computer. I don't have and cannot afford a decent multi-track soundcard (one of the reasons I'm using the cassette recorder, another being really cool drum sound). This means I cannot record the tracks seperately and sync them afterwards, because the speed of each playback isn't 100% reliable.
I have a USB guitar link from Behringer, which I could use and has one mono plug. Pulse Audio picks that up as a seperate input and with Jokosher I can assign line-in left and right to two seperate tracks and the USB link to a third one. The problem is however that Jokosher constantly freezes up and I've never been able to make it work properly. So my question is: is there any other way/software I could use to record from two seperate audio sources?

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 have been messing around with Cinelerra after doing a Final cut pro course some time ago but as it needs to be told what to do more i am finding it hard going. When I have track 1 that has audio and video and also track two has the same then i mute the audio in one and block out the video in then other. Then add effects. It is then moving audio or video around and nothing is in sync anymore. Not where i put things. I undo the effect to see if it will go back but no go. I try to undo to the point where maybe i missed something but nope that is not it. Inevitably i have to redo everything again but then i end up with the whole thing out of sync again. I had a previous install of Ubuntu and Cinelerra and i don't remember striking this problem. Am i not loading the tracks properly. I don't have a good work flow with this and i know i should try something more simple but i am impatient to edit videos i have had for years and years and years. I never did learn editing in windows so i am happy to be getting somewhere in Linux.

I would like to know how to demux the audio from a flash video file (copied from /tmp while browsing a video site). I would prefer to avoid re encoding if possible.

I use abcde to rip and encode all my music. It works great especially the option of ripping an entire cd to one flac or mp3 file, this was great for Sleep's Jerusalem. Anyway I have a cd by the Melvins (the Maggot) which they famously split each track into two tracks midway through the song. I would like to know if there is a way to rip them into "whole" tracks?

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

I have a video file in which the audio runs faster than the video, so they quickly go out of sync. The way to fix it would be to separate the audio and video streams, speed up the video (the audio is FINE, it's the video that's wrong), and then recombining them. What is the easiest way for doing that?

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.

I've been using lxdvdrip to rip a couple of DVDs that I own to my hard drive; and I usually am able to use just one command and let it do its thing, instead of waiting for all the prompts ("Select audio tracks?", "Specify burn location?", etc), using something such as 'lxdvdrip -u=a -a=2 -fv=~/film-dvd -lang=en -bp=0'. The problem is that this will only work for movies that have English audio tracks, and I have quite a few movies in other languages. There's no way to simply predict what audio tracks a movie will have, short of playing it and cycling through them all.
There doesn't seem to be an lxdvdrip option to specify a language other than German, English or French; you have to choose it manually. Is there a way -- using lxdvdrip or something else on the command line -- to list the particular properties of a DVD, specifically what audio tracks it has? Something kind of like the "exiftool" command for listing EXIF data.

I've run into something very interesting over the past several months with audio CDs and KDE 4.3.1. Background: I've got two computers running Slackware 13 --stable with Vincent Batts's KDE 4.3.1 packages. One of them is a desktop running Slackware64 and the other is a laptop running 32-bit Slackware. The two computers are running almost the same software too. I like to listen to audio books that I get from the library on my MP3 player. The vast majority of them are CD audio (as opposed to MP3 books), so the disks simply have a whole bunch of .cda tracks on them when I view them in Windows.
HOWEVER, when I view them in Dolphin or Konqueror, I get several folders offering the files in different formats. For instance, there's a folder for the individual tracks as .wav and another for .ogg files. The folder that I really like is one called something like "Full CD," which offers the whole disk in one file in four different formats. That's the one I like. I can get the whole disk in one OGG file so that an entire book is just 12 files on my Sanza. The only thing that seemed strange was that it took for freaking ever to "copy" from the CD to my hard drive.
I think I figure out what's going on! I think that Dolphin is actually calling K3B when I click on the audio CD and when I "copy" from the CD to the hard drive, it is actually encoding the .CDA files. The Problem(s)Until recently, the burn (if that's what it is) was slow on the 64-bit machine, but it worked. However, in the last week or so, it seems that the last few bytes of data to burn are taking forever (like an hour or more) to do so. I hear a strange clicking from my drive, so maybe that's the whole problem. I'm going to get a new drive and see what happens. The burn works well on my 32-bit laptop, but it doesn't recognize audio CDs when I insert them like the 64-bit desktop does. I need to open Dolphin and type 'audiocd:' in the toolbar for it to recognize the disk. Then everything works well. So: Am I understanding what's actually going on with audio CDs? Why does my desktop computer recognize audio CDs when they're inserted, but the laptop doesn't?

So I work off and on doing live sound work and I am interested in starting to record some of the shows I work on. Naturally I only run Linux based operating systems on my computers so I was wondering if anyone could recommend a good piece of hardware for recording 8-16 tracks that fully supports Linux. I have firewire and USB interfaces on my studio laptop.

I've searched high and low, and can't seem to find a solution to this. I'm running a Dell Inspiron with an HDMI output with 10.10 through the tv. I want to get HDMI sound output for VLC, but I also want S/PDIF output (to the stereo) for Musicplayer. I can test and use the HDMI in the sound preferences sound/preferences/sound, but when I try to do the same for the internal card and click 'test speakers' the sound program closes itself. When the machine was a windows machine, it had PowerDVD outputting to the TV and Mediaplayer outputting to the stereo. I'm aiming for a similar set up in Ubuntu.

I am using Ubuntu 10.04 LTS - the Lucid Lynx. I am using the laptop to play video files and view it on TV using HDMI output. No problems. Requirement: to play simultaneously a different media file and be able to listen through say headphone / laptop speakers. While a movie audio is only heard on TV, other audio is heard only on laptop speaker.

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/

i'm using optical s/pdif output, called "hda intel, ad198x digital (iec958 (s/pdif) digital audio output)" in phonon preferences. sounds works just fine -- except i can't use multiple audio sources simultaneously: for example amarok+videos is a no-no. only the first audio source plays, so i have to close amarok in order to listen to any flash videos. i had this problem already with opensuse 11.2, but couldn't figure it out (using 11.3 now).
i just recently got a hunch that it might have something to do with mixing and the s/pdif, and i tried using analog output ("hda intel (ad198x analog)"). lo and behold, it works! amarok+flash that isash still doesn't still consider this a major leap forward.however, i'd like to keep using my optical output.
