Ubuntu :: Extract Audio And Then Convert To Mp4 Format?
Feb 7, 2010
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
I see lots of threads on converting your CDs to MP3s, but I want to do the opposite. I want to burn MP3s into CDs that will play on older CD players that dont have MP3 support.
So how do I do it? I have Mint on this particular computer, which is like having Medibuntu already I think.
just wondering is there a simple script to convert datetime to UTC format. I have been searching different forums but most answers are for converting UTC to datetime. For example what is a simple command/script to convert todays datetime to UTC format i.e. '2009-10-09 11:47:59'.
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 have some .mp4 files. While open this file using vlc-player the resolution is fine. Then I convert this .mp4 format to .avi format using "ffmpeg". While open the .avi file using vlc-player the resolution is not fine.

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 guess many guys got lots of eBooks in PDF and other formats, but some e-readers like Sony Reader, Barnes & Noble Nook, Hanlin eReader and phones/devices using Android only support specific formats with their default reader apps, especially newly-released and hot iPad. What's the best way to convert those PDFs to ePub (ePub is the only ebook format iTunes accepts)?
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 have a PDF File here with upright ("portrait" format) pages, and I want to convert it so that each page gets "split" in the middle and becomes two wide ("landscape" format) pages.
Something like "print multiple pages on one page", only reversed
Is there any way to do such a thing with CUPS or something?
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 just wanted to know what people think is the best video encoding program. I want to be able to convert any video files to any format, mostly x264, avi that sort of stuff. I used AVS encoder in windows.
I emailed myself a video. I took with my ipod touch, and its in .mov format which ubuntu doesn't support. I have an app called arista transcoder (a little slow, but very handy), which, for some reason, isn't able to convert the video. its strange because I was able to convert a few other videos from my ipod (same format) into .avi files last week. Arista says something about an unrecognized media type.
What is the best way using Linux to convert a DVD from NTSC to PAL format? I have a DVD made from an HD recording using a video camera. Made a standard DVD by copying from the Camera to the DVD recorder [ergo NTSC].
Is there any way to convert *.flv and *.mp4 videos to *.swf format please? I have some videos downloaded with .....-dl that are in the above format. I would like to make them all into SWF files, so anyone can watch them in their browser, without having to find a suitable multimedia player.
