Ubuntu Multimedia :: Ffmpeg Audio Merge With Video Merge
Feb 22, 2011
I am using ffmpeg for merge wav files to a mov video. My doing is below
1. First extract audio (wav file) from video
2. Create wav file from mp3 track 1
3. Create wav file from mp3 track 2
4 Merge extract audio from video with track 1 and track2.
Now finally create a new video with original video's video stream and merged audio stream.
Process is working. However final video is 3-4 times greater than original one. I want that final video should be near about size of original video. As I understand, all three wav files (created from ) make video larger.
Example commands i using is as below:

how can i merge two files with ffmpeg?
one is : /home/pt/t/pa1.flv
the other is : /home/pt/t/pa2.flv
1 o merge with ffmpeg
ffmpeg -i /home/pt/t/pa1.flv -i /home/pt/t/pa2.flv -vcodec copy -acodec copy /home/pt/t/dd.flv
the problem is: the merged file ( /home/pt/t/dd.flv ) just contain one file--the first one
/home/pt/t/pa1.flv,there is no the second file--/home/pt/t/pa2.flv in the /home/pt/t/dd.flv

I am attempting to rip a dvd with dvd::rip. All goes well till it finishes ripping. It fails to merge the audio and video into one file. I am getting an audio ogm file and a video ogm file for the movie. I am currently running 10.04 kubuntu. Here is the log for the rip: (I apologize for the length but I did not know what is useful and what is not.)

I have a video which I've edited to my satisfaction but when I click play it seems to only play the first clip of video. How can I merge all my clips so it will continue to play through the whole thing?

I'm using Handbrake 0.9.5 for encoding and I'd like to add a "hard-subtitle" to a video : the subtitle has to be a part of the video. I've seen on makeuseof.com that we could hard-sub a video thanks to the "Forced only" option. On Ubuntu 10.04 amd64, I don't have any checkbox for this option while importing SRT file. I've got the checkbox for "subtitles" I add by clicking on the "+ Subtitle" button, but it seems to be useless (I had a video_name.srt next to my video_name.m4v video file to re-encode). Is Handbrake now supporting only soft subbing ?

How can I join the two parts of a stereoscopic movie to get a side-by-side one?
I can expand the left file, that way all I'll need is to paste the second one on top of it, with something like this:
mencoder left-file.mkv -o side-by-side.avi -oac copy -ovc lavc -of avi -vf scale=1280:720,expand=-1280:0:0:0 -sws 3 -lavcopts vbitrate=16000
Any idea which tool should I use on a Linux system?

I'm trying to write a bash script for gpodder to automatically convert video podcasts to play on my media player. I'm using ffmpeg for the conversions (compiled myself with all codecs enabled). I'd like to avoid resampling the video or audio whenever it's unnecessary but ffmpeg seems to want to resample my video even if I only give it audio parameters to change.For example I have a test video with the following parameters:
Code:
Stream #0.0(eng): Video: h264, yuv420p, 640x480, 1394 kb/s, 29.97 fps, 29.97 tbr, 2997 tbn, 5994 tbc
Stream #0.1(eng): Audio: aac, 44100 Hz, stereo, s16, 159 kb/s

i am using Ubuntu 11.04 on my computer system. I urgently need a good video converter for converting videos.I have already installed FFmpeg and men-coder,Winff etc. The problem is each has its own drawback.For instance ffmpeg cannot convert a .avi to .3gp with audio working. My preferences are the converter should be user friendly, should support all popular video formats.

Iam aware of the way on how almost every file can be converted to .pdf within Ubuntu 10.04 using "Print to File" function. But is there a way to merge multiple files to create one .pdf? OR Is there a way to merge multiple .pdf files to create a single .pdf?

So I found PDftk which seems promising Im also looking at the commands which are also very powerful..but I think its kinda of laborious to type all my 50+ pdf files in the command prompt I have the front end of pdftk I was wondering is there a program (I have Pdf sam and Pdf Shuffler) that will allow me to import unlim. number of files and then just jam it into one big PDF file?

I've got a 500gb hard drive.
-sda1 is 400gb (ubuntu 9.10/32bit/ext3)
-sda2 is 50gb (ubuntu 10.04/64bit/ext4)
I would like to expand my lucid partition now and eventually get rid of my 9.10 partition. I've got an 80GB virtualbox file sitting on sda1 that I need and want to expand sda2 now so I can first copy the VB file over, then expand sda2 completely. I just finished creating sda3 ext4, but cant figure out how to merge it with sda2 (well really sda6). Please see image. [URL]

Is there any bash script to merge pdf files in a directory and sub-directory and rename it as the directory/sub-directory name?Like for example using GhostScript/PDFTK/PyPDF etc?I'm kinda new where it comes to bash scripting.I found this script on a blog that seems to do what I want, however, the bookmark functionality is not of importance to me (and requires jPDFBookmark - which I can't manage to install)
Code:
#!/bin/bash

I'm sure I'm not the first to have encountered a problem with synaptic when I tried to load it up to install a new bit of software (in this instance help screens for OO).However when I did I got the following error message E: Encountered a section with no Package: headerE: Problem withMergeListvar/lib/apt/lists/mirror.ox.ac.uk_sites_archive.ubuntu.com_ubuntu_di sts_jaunty_restricted_binary-i386_PackagesE: The package lists or status file could not be parsed or opened.E: _cache->open() failed, please report.
When I opened the file that had the apparent prolem < var/lib/apt/lists/mirror.ox.ac.uk_sites_archive.ubuntu.com_ubuntu_dists_jaunty_restricted_binary-i386_Packages > it transpired it actually contained the html page for the router ?? which seemed wierd to me.However I have recently I changed to a new ISPSo after a bit of a search, nothing explicity had my problem, and I was a bit stumped. Then I suddenly had a thought, after reading someone else how did something similar.... I then did the following....
Code:
sudo mv /var/lib/apt/lists/mirror.ox.ac.uk_sites_archive.ubuntu.com_ubuntu_dists_jaunty_restricted

In ubuntu 10.04 and 10.10 there is now xorg file. Is there some way to merge the default graphic settings with my own xorg file? I'm currently needing to use and xorg file for my via graphics cards, which works fine. However, some functionality is missing. the icons have lost transparency and the unity menu doesn't allow click and drag scrolling anywhere (like a tablet). If I delete the xorg file and run the default, I get all the crisp clear cut of unity but of course I get performance problems everywhere else... i.e I cant plug a multiple screen in and video playback is crap.

Is there any way to Merge hard drive partitions? I didn't really know what I was doing during install and wound up leaving myself with over 100GB of unallocated hard drive space. if I create a new partition out of this, could I possibly merge it with another? and if I do, should I merge it with root or home? I am using 10.10, by the way.

I'm trying to encode a wmv file to flv with ffmpeg. The video codec is WMV3 and the audio codec is wmap (Windows Media Audio Professional). The command I use is:
Code:
/usr/bin/ffmpeg -i <input file>.wmv -s 640x350 -b 1024k -r 25 -ar 44100 -ac 2 -y <output file>.flv
Output:
Code:
FFmpeg version 0.5-svn17737+3:0.svn20090303-1ubuntu6, Copyright (c) 2000-2009 Fabrice Bellard, et al.

Stream mapping:

Stream #0.1 -> #0.1
[wmv3 @ 0xb32c00]Extra data: 8 bits left, value: 0
Unsupported codec (id=86056) for input stream #0.1
As you can probably see the audio codec is not supported. Is there a way to encode WMV3+wmap with ffmpeg or any other tool in Linux? Windows Media Encoder in Windows is able to encode such files to a supported codec. For example: WMV3+WMA2/WMV2+WMA2, I could then encode it in Linux. I'm trying to find a way to directly encode WMV3+wmap in Linux.

I have a movie split into 3 iso image files, say, movie-1.iso,movie-2.iso, and movie-3.iso I did the following:
[ewn]# cd /mnt
[mnt]# mkdir disk1 disk2 disk3
[mnt]# mount -t iso9660 -o ro,loop=/dev/loop0 /media/Hitachi_SATA_2TB/iso_files/Movies/movie-1.iso /mnt/disk1
[mnt]# mount -t iso9660 -o ro,loop=/dev/loop1 /media/Hitachi_SATA_2TB/iso_files/Movies/movie-2.iso /mnt/disk2
[Code]....
the files for disk2, disk3 are exactly the same except disk2 has 2 .vob files instead of 3. Can I make this work by changing the names of some of these files before merging them into one directory and then running the mkisofs command to create a new single iso image? If so, what names do I give so that the movie plays correctly? If not, just how do you do this?
