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

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...
View 3 Replies View RelatedI'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"

View 9 Replies View RelatedI'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.
View 10 Replies View RelatedI 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.
When ever I extract a file from a .tar or whatever, it isn't detected. I notice this mainly when i'm using xampp. I copy zip up all my files on one computer, load ubuntu on another, extract the files to the web folder (htdocs) and then I get nothing. However, when I manually create the files directly on my computer as opposed to extracting them, they appear.
Is there something I need to do in order to have these files appear? Is there some sort of file system refresh? Or am I being a complete idiot?
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.

Im trying to extract the contents of a zip file but I want to extract it to my own directory. I'v tried -d from unzip but that just puts the contents of the zip into that directory.
But I want to extract the contents of the first (root) directory in the zip if there is only one directory in the root of the zip else just extract the files/folders in the root of the zip file (if there are more then one files).
e.g. test.zip contents the following dir structure:
test.zip

- folder-4

I just installed Ubuntu for the second time, first time was like 2 years ago and my pc was an oddball and some stuff was just not supported properly. Anyways.. I've got the latest build of Ubuntu installed, everything is working fine, just one problem.
I have many, many, many files that are archived in multiple .rar's. Like .r01, .r02, etc... I have them all copied over to the harddrive, but cannot extract what is in them. Also, I have some of these .rar's archived in a single .rar because of windows being stupid and not letting me copy them to my external drive as the names of them were too long for windows to handle. Those .rar's will extract a couple of the .r01, etc.. files, but not all of them.
I can't seem to extract it with any archiver, and when I used unrar from the console, I get this:shai@shai-desktop:~/Desktop$ unrar c1700-adventerprisek9-mz.124-15.T8.rarunrar 0.0.1 Copyright (C) 2004 Ben Asselstine, Jeroen DekkersExtracting from /home/shai/Desktop/c1700-adventerprisek9-mz.124-15.T8.rarExtracting c1700-adventerprisek9-mz.124-15.T8.image Failed 1 FailedYou can see that it can open the archive but it can't get the file inside.
View 2 Replies View RelatedI have installed unrar-free, and I am trying to extract a file from a .rar archive (actually the file is split into several archives).
When I choose one of the .rar files and open it with Archive Manager, there are no errors and the file to be extracted shows in the Archive Manager window. I then choose to extract it, and after that I click on "show files". But when the folder supposedly containing the extracted file opens, the file isn't there.
Maybe relevant info:
I am running latest stable version of Ubuntu, as the user that was created during the Ubuntu installation. The files are in my "Downloads" folder, and the Archive Manager window says that the .rar file is read-only.
