Ffmpeg

Hi

I have about 100 RA files (RealAudio) that i want to concatenate together into one big mp3 file in the correct order. I've heard ffmpeg can do this, but I' not sure how. Can anyone help me with this?

Thanks

Hello everybody

I am running Linux Mint 17.1 Rebecca with the Cinnamon Desktop.

I have experiences with the ubuntu derivatives and ffmpeg and avconv are always avavilable the repos, this time both aren't available

Here are the commands I typed:

apt-get update ; apt-get upgrade

After the packages were upgraded. I ran these commands. Below are there outputs.

Quote:
apt-get install ffmpeg
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package ffmpeg is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'ffmpeg' has no installation candidate

apt-get install avconv
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package avconv
This nevered happened to me before with linux mint in prior versions.

Any ideas?

Hi

I have some video files where audio dialogue is low but action scenes are loud. I was searching the web on how I can fix this and I found this link http://lifehacker.com/5920290/how-to...en-really-loud

It is an excellent tutorial from lifehacker.

I was wondering if ffmpeg, mplayer/mencoder, handbrake or other commandline program can do the same of increasing the low audio dialogue while keeping the loud action scenes the same audio level? Thanks

I'm sorry to ask such a simple question but every time I think I figure something out or think I'm going somewhere get stopped dead in my tracks. My friend installed linux on my computer and then moved away immediately so I have no one to help me!

I downloaded the webcam program Cheese. I found through some tutorials that I have to copy the folder to the /opt/ folder and the only way to do that is through the terminal. I found this tutorial and still can't manage to copy the folder. These are the problems I run into:

1. I don't know where to open the terminal. I've tried opening it from the extracted Cheese folder in my downloads folder and from the /opt/ folder itself. It opens up but:
2. when I type the command sudo cp -r cheese /opt/ it will ask for modernnewspeak's password. When I try to type this in nothing happens, even though it JUST let me type in the command. I pressed "enter" thinking maybe it was hiding my password and I get the message "cannot stat 'cheese'. No such file or directory"

please tell me what I'm doing wrong! I tried to follow that tutorial and look through the FAQ here but I cannot figure this out. Thank you in advance!

Hello,

I am working on a board (sbc6000x with at91sam9261 micro, linux 2.6.24 to be precise) and having some fun making script i wanted to make real application.
The board is coming with a cross compilation toolchain. When trying to make a simple "hello world" executable to print on the terminal there is no problem.
I open my terminal, give the path of the compiler, cd into the folder where my .c file is and then i type :
Code:

arm-linux-gcc -o hello hello.c

Which create my executable "hello" and this one is working. But like i said, this program only played with the terminal.

The board is starting with a script calling another executable which use the lcd display, i have the source of this executable. My idea was to look at what was in the source of this application (lots of folders and files) in order to understand how it was working. I wanted to test the toolchain on the source (with the makefile) to see if i was able to generate an executable from a application with folderS/fileS but when i try to "make" it i have this error.

In my understanding this is an object file but aside from that i don't see why it would not works.

Thank you for your future answers !

I'm just getting into Bash scripting, and would appreciate some help with this question. My music collection is split into a smaller, "active" set, kept on my laptop, and a much larger collection on an external hard drive. I've just converted some of the larger filetypes on my "active" set to *.mp3, and now want to move all the original files (*.flac) to the external hard drive. I need some help putting together a command or script that will recursively search my active music set for *.flac and then move them, but keeping the source directory structure. Some or all of these subdirectories may not exist on the destination.

eg. On the active music set, I may have:

/Music/artist1/album1/(a mix of *.mp3 and *.flac files)
/Music/artist2/album1/(a mix of *.mp3 and *.flac files)

and on the hard drive

/Music 2/artist1/album2/(the contents of the album)

So when copying, it'll need to create "/album1/" in "artist1" on the destination, and also "/artist2/album1/"

Thanks in advance!

In the (x)ubuntu updates, I keep getting chromium-codecs-ffmpeg-extra, which is part of the Chromium browser update. However, I don't have Chromium installed.

I do have Google Chrome. Is that the reason? But if so, how would they know I have Chrome?

Hi

I am trying to fade in audio at 39 seconds into the video with existing audio.

It did work, the mp3 file fades in at 39 seconds, however the original audio from the video is silence or removed.

Here is the code I've use.

Code:

ffmpeg -i audio.mp3 -i test.mp4 -c:v copy -strict experimental -shortest -af 'afade=t=in:st=39' test.mp4

How can I fix this? Thanks

In an attempt to solve another problem (transfer .avi files from a camera to a computer) I uninstalled Tumbler in the terminal via this command:

sudo apt-get remove tumbler

I was unable to transfer the .avi files so I re-installed tumbler in the terminal via this command:

sudo apt-get install tumbler

Joe here helped me find a solution to my transferring the .avi problem so that is no longer an issue, but when I turned my computer on this morning I got a window that said Tumbler had crashed. (see screenshots)

I know Tumbler has to do with thumbnails but I don't know the full scope of how. My thumbnails seem to be working fine as far as I can tell. So am I concerned about the crash, do I do anything about it or just let it go? Thanks.

I searched the forums for my title and I am not finding exactly what I am looking for. I am not using a program to send mail, such as Thunderbird or whatever. I simply want to be able to send mail from my Ubuntu 14.04 DESKTOP version for logging. I use a program called Logwatch (used alot in RHEL or CentOS) to monitor the server itself. The program sends mail to the root user account on the machine, which I can check and see, and within the program conf file, I can add an external email address, but it never sends.

I'm familiar with the SMTP concept of sending mail, outgoing mail server authentication, etc. I don't care to run this box as an SMTP server, but I understand that I need some sort of SMTP or MTA program to send mail into the real world. I tried Postfix but couldn't get that to work, and the Logwatch program wants to use sendmail, so I installed that but I am having the same issue. I am sure it is a step I am missing.

I also can't figure out how to get the 'mail' cmd from Terminal to work. I use this command:
Code:

mail -s "test" | /usr/sbin/mail myemail@domain.com

it follows through the subject, CC, body, but when I try to hit either . or CTRL-D, it never sends the email, in fact is does nothing.

I also tried sendmail with this command:
Code:

sendmail -v my@email.com < /dev/null

I was just trying to send a test email. It logs into my SMTP mail server, which I already configured, and it tells me to type out the mail, then end with a "." by itself on a single line. I try this and it just sits there.

I am missing SOMETHING when trying to actually send the mail. I can get it written with subject and body, connected, but it never sends and I am probably missing a / or something.

I did find and follow these instructions, but it still isn't working with sendmail. If I need to go back to Postfix, I can do that, I don't honestly care what I use, I just want some programs such as Logwatch to be able to email me.
