Is there an application available to generate videos of waves of an audio file? I've seen this kind of things in player's plugins but they are normally just viewers and won't generate a video from it.
View 2 RepliesMy apt gets noise from outside. I would like to generate a white noise audio file and play it to block outside noise. I would prefer something like the low frequency hum of a big fan. How can I generate this file in using linux tools?

I do not have the same problems on the alternate boot. There are other performance comparisons where the windows boot runs smoother and faster. Is there any work I can do in order to optimise my fedora boot in this capacity?

So when I play the flv the audio is added and the video quality is not changed.I tried:ffmpeg -i 20.flv -i 20.wav -vcodec copy -acodec libmp3lame new_file.flvbut I an error "Could not write header for output file #0 (incorrect codec parameters ?)". I'm guessing because it is a vp6 flv codec.Is there a way to just add an audio file to the flv? There is no audio in the current flv. I cannot lose any quality in the video.
View 1 Replies View RelatedI'm trying to extract the audio from an mp4 video file and convert it to mp3 using ffmpeg. The problem is that the resulting audio file is only 3m2s long, whereas the video file is 8m15s long. Anyone know why the audio file is being truncated? Am I doing something wrong? Apart from being truncated the mp3 file plays perfectly. Here's what ffmpeg has to say about the video file:
Code:
Seems stream 1 codec frame rate differs from container frame rate: 59.83 (59834/1000) -> 29.92 (359/12)
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'Part1.mp4':
Duration: 00:08:15.60, start: 0.000000, bitrate: 541 kb/s
Stream #0.0(und): Audio: aac, 44100 Hz, stereo, s16
Stream #0.1(und): Video: h264, yuv420p, 1152x720, 29.92 tbr, 29.92 tbn, 59.83 tbc
And here's the command I'm using to extract and convert the audio:
Code:
ffmpeg -i Part1.mp4 -ab 128k Part1.mp3

View 4 Replies View RelatedI've been giving the task to go to a Linux console as root. and generate a ssh rsa 4096bit key, and copy the private key to a USB drive.
1) What command should I use here? ssh-keygen -t rsa -b 4096 ?
2) Do I need to append the new private key to the authorized_users file? Which file exactly must be appended there? Would this be sufficient?
mkdir -p /home/myuser/.ssh
cat id_rsa_LOCAL.pub >> /home/myuser/.ssh/authorized_keys
Should any special permissions be applied to this file?
3) Which file must be sent to my usb drive so that I can take it home to connect with?

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?
View 7 Replies View RelatedIs 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.

A. Is there a preferred Linux distribution that will make this easier?
B. What is the best format for audio and video files that will be viewed variously on Linux, Mac, and Microsoft operating systems? Files will need to be played on older versions of operating systems and may need a free or very low cost software to play (e.g. play on Win2k)
C. What software is best for recording the audio or audio-video files? Some additional funding might be justified for this software, particularly if it can also support live streaming.
D. What software is best for live streaming both on the file creation and the listening-viewing sides of the process?
Ideally we would like to have a single software suite to live stream, and make downloadable audio or audio-video files for later download, and not require those listening and viewing to have to install additional software. Keeping file sizes small is also desirable because some of our users will probably only have dial-up internet.

The problem is that none of the video players doesn't play video, they show only black window and play audio.

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 recently installed Fedora 13 in my laptop, installed the audio codecs(mp3..and etc) and worked just like a dream. But every time I try to play a mpeg, avi, mov file in a player (vlc, xine, mplayer) I get no video, just a black screen. But I get the audio from the video.
View 9 Replies View Relatedim a little familiar with opensuse..but when i formatted my pc after the installation of opensuse i realized i missed all the audio and video codecs...now i cant even listen to mp3s let alone watching videos.i remember there was a forum post explaining how to install all the audio and video -well mostly- codecs..could you explain how i can install audio and video codecs?
View 3 Replies View Relatedafter installing opensuse 11.3 i am finding that i cannot recieve any audio with video with any application.
i can hear certain types of audio, it seems any audio that is not attached to video. i can hear the welcome chime through my speakers after i log in to opensuse and i can also listen to .mp3 files played with amarok. i can watch videos with multiple players, videos videos etc., but there is no audio happening with the video.
i am thinking now this may actually be a hardware problem, since it seems to persist with different software, and only with audio attached to video. i'm thinking maybe there is a problem with my graphics card and its driver (or a lackthereof), although i'm unsure of why i can still watch video. i don't receive any error messages or anything, nor have i attempted to manually install any drivers for my existing hardware. i tried cranking every volume control i could find, including the system volume, but still no volume with video (its weird, its like i can hear it a tiny bit when i crank it, perhaps this is just the internal system beep speaker trying to fill in for the gfx card?).
the card i'm currently using is an nvidia card and although its not exactly old, i have read about some problems with nvidia being reluctant to produce drivers for linux in the past. after some brief googling of nvidia and linux, i was surprised to see that nvidia has an entire portion of their site devoted to unix/linux and open source drivers (perhaps they're doing better now).
is there any way that i can troubleshoot this problem, or do you think the solution is simply purchasing another graphics card from a vendor that has a good reputation for linux support?
I installed ubuntu there is another problem iam getting is that i cant play any audio file or video file when i clicked on the file it is saying search for suitable codec when i click on search it is.
View 3 Replies View Relatedwhen i had windows xp i used to convert almost any videos video into audio (the whole video into audio) by going to [url], downloading vdownloader and just inserting the url in the box provided; waiting for a couple of minutes and having an mp3 format file at the location that i want it to be in the desktop. when i searched for something similar for linux, because vdownloader was an .exe file and obviously wasn't going to work on ubuntu.
i found that i could get a video downloaded from videos but not an audio - i wait for the video to finish buffering; click on places; computer; file system; tmp; then rename the video folder and copy/relocate it to where ever on the desktop. ending with this video format "flash video (video/x-flv)". my question is: is there a linux program where i get to convert the entire video format to an audio format, possibly mp3?
