Ubuntu Oneiric Audio Video Conversion
Audio / Video conversion
Mencoder is part of the MPlayer set of libraries (that also uses several of the FFMPEG libraries) for audio/visual conversion, including from DVD (.vob) format to other video formats. Some examples of usage are here.
FFMPEG video / audio conversion
FFMPEG is the swiss-army knife of video and audio format conversion. It succeeds when no other program can. It is free and open source. If it not yet installed on your system as part of another package (it is used by many video/audio editors), then install it:
sudo apt-get install ffmpeg
For examples and further information, see this section.
- FFMpeg requires that multiple restricted extra codecs be installed. This can be done in a single easy step from the command-line Terminal:
sudo apt-get install ubuntu-restricted-extras
WinFF is a free, GPL-licensed open source GUI frontend for FFMPEG. Install:
sudo apt-get install winff xterm
- Menu -> Applications -> Sound & Video -> WinFF
Join video segments
Individual video segments (MPEG-2, for example) can easily be joined:
cat samplevideo1.mpg samplevideo2.mpg samplevideo3.mpg > samplevideo123.mpg
- You can then write the resulting MPEG-2 file to a DVD and play it in most DVD players.
Split a file into segments
Any file can be split into segments using the Linux command:
split -b 1440k my_big_file
which will split my_big_file into equal segments of size 1440 kb.
Save any streaming Flash video
An easy way is to install the Video Download Helper plug-in for Firefox.
Otherwise, most Flash videos download to the /tmp directory while you watch the video, creating a randomly-named video file there (such as Flashuh4G6s). When you close the webpage, this file in the /tmp directory will be erased. After the entire video has downloaded, but before you close the webpage, copy that file (such as Flashuh4G6s) to your home directory (where it will not be erased). Of course, for this to work, you must change your Flash (or Gnash) settings to allow an unlimited buffer. While watching your Flash video, right click to bring up the Flash -> Settings window. Set the Buffer to "Unlimited."
Once you have copied the file, rename it appropriately with the .flv added to the filename. You can then watch it using VLC or Mplayer.
Here is another method that involves making a symbolic link.
Save rtmp / flv streams
flvstreamer is a command-line application to dump rtmp streams. Install:
sudo apt-get install flvstreamer
Example of usage:
flvstreamer -r "rtmp://host/dir/file.flv" -o filename.flv
If you see the following the "WARNING: Download may be incomplete, try --resume!" message, try to use the --resume option:
flvstreamer -r "rtmp://host/dir/file.flv" -o filename.flv --resume
Convert Flash video audio to mp3
Once you have downloaded flash video content (.flv) from the Internet (using the Video Download Helper plug-in for Firefox, for example), the audio component can be converted to an .mp3 file. (This will work for any type of video file, not just Flash.) For details, see this section.
2ManDVD is a GUI utility for creating DVD videos. It is the successor of ManDVD. Choose the version for your architecture and install it from the 2ManDVD website. Click on the download link and select to open it with the GDebi Package Installer (default). (If you have previously installed ManDVD you must uninstall it first.) For a usage tutorial, read this 2ManDVD guide.
- Menu -> Applications -> Sound & Video -> 2ManDVD
DeVeDe is a program to create video DVDs and CDs suitable for home players (i.e. VCD, sVCD or CVD) from any source video file that is supported by MPlayer. Choose the version for your architecture and install it from the DeVeDe website. Click on the download link and select to open it with the GDebi Package Installer (default). For a usage tutorial, read this DeVeDe guide.
- Menu -> Applications -> Sound & Video -> DeVeDe
ManDVD is a QT-based DVD authoring tool which accepts several different file types as input. Install:
sudo apt-get install mandvd xine-ui
DVD author allows you to create menus and format your MPEG-2 videos onto a DVD disc so that you can play it in a commercial DVD player. DVD Author is a command line tool, but several GUI's exist. Install:
sudo apt-get install dvdauthor
QDVDAuthor is a Qt-based GUI for DVD Author. A package for Oneiric does not exist, but the Maverick package can be used.
- Enable the Maverick multiverse repository temporarily by adding it to the Synaptic Package Manager Origin of Packages ("Other" software):
- Menu -> System -> Synaptic -> Settings -> Edit Origins -> Software Sources: Other Software -> Add...
deb http://us.archive.ubuntu.com/ubuntu maverick multiverse
- From the Get and Remove Software menu (of Synaptic), install the qdvdauthor package (and the qdvdauthor-common package if it is not automatically installed as a dependency).
- Once the download/installation is complete, disable the Maverick multiverse repository (to prevent conflict with other Oneiric packages).
- Download and install the addons:
cd /tmp wget http://qdvdauthor.sourceforge.net/data/masks.tar.bz2 -O masks.tar.bz2 wget http://qdvdauthor.sourceforge.net/data/buttons.tar.bz2 -O buttons.tar.bz2 wget http://qdvdauthor.sourceforge.net/data/alpha_trans.tar.bz2 -O alpha_trans.tar.bz2 cd /usr/share/qdvdauthor/ sudo tar -xjf /tmp/masks.tar.bz2 sudo tar -xjf /tmp/buttons.tar.bz2 sudo tar -xjf /tmp/alpha_trans.tar.bz2
- Menu -> Multimedia -> QDVDAuthor
Follow instructions in the Quick-Start Guide:
- QDVDAuthor -> Help -> Quick-Start Guide
For a tutorial on authoring DVDs, see this guide.
ToVid is a collection of tools to create a DVD from a number of different video formats. A GUI is available. Install:
sudo apt-get install tovidgui tovid
Other DVD authoring programs
There are several other DVD authoring programs. For additional information see the Ubuntu Community pages. Packages include:
- Bombono, a GTK-based, GUI DVD authoring program. Install (requires multiverse repositories to be enabled):
sudo apt-get install bombono-dvd
- KMediaFactory is a KDE-based DVD authoring frontend for dvdauthor. (The DVD folders can then be burned to disc using K3b.) Install (requires multiverse repositories to be enabled):
sudo apt-get install kmediafactory
Ripper X CD Ripper/Encoder
Ripper X is a GTK-based (i.e. Gnome) open source utility to rip CD audio tracks to OGG, MP3, or FLAC formats. It supports CDDB lookups.
sudo apt-get install ripperx
Asunder CD Ripper/Encoder
Audex CD Ripper/Encoder
Audex is a port to KDE4 of the KAudioCreator package used in KDE 3. It can create output for LAME (MP3-compliant), OGG Vorbis (oggenc), FLAC and RIFF WAVE. Install:
sudo apt-get install audex
Gnac (GNome Audio Converter)
SOX (encodes/decodes audio)
sudo apt-get install sox
Install MP3 support for SoX
- Install the MP3 libraries (if not already installed):
sudo apt-get install libmp3lame0
- For simple conversions, I have found FFMPEG to be easier, and FFMPEG already has mp3 support. Example:
ffmpeg -i audiofile.m4a -ab 128k -ac 2 -ar 44100 audiofile.mp3
- where -ab specifies the bit rate, -ac specifies the number of channels (in this example 2-channel stereo), and -ar specifies the sampling frequency.
CDs and DVDs
Brasero (CD/DVD burner)
Brasero is a CD/DVD burning application that is now part of the Gnome desktop (but can be used with any Ubuntu derivative). If not already installed:
sudo apt-get install brasero
Gnomebaker (CD/DVD burner)
Gnomebaker has been the default CD/DVD burning application for the Gnome desktop. If not installed:
sudo apt-get install gnomebaker
K3b (CD/DVD burner)
k3b (KDE Burn Baby Burn) is the default KDE CD and DVD burning utility included in Kubuntu, but can run well in Gnome. (Due to licensing requirements, mp3 capabilities must be installed separately as the libk3b6-extracodecs package). Install:
sudo apt-get install k3b libk3b6-extracodecs
Normalize audio levels
Volume normalization for an audio CD requires a separate external plugin. Install:
sudo apt-get install normalize-audio
Then select normalization:
- K3b -> Project -> Properties -> Advanced -> Settings:Normalize volume levels (ticked)
- Recent versions of k3b have a bug that doesn't properly recognise normalize-audio. See these tips (or these tips) for a workaround.
Cdrecord error 254
Note: The solution here has not been verified, and the problem may lie in a different module than cdrkit, such as libdvdread. This section is under construction.
The problem usually occurs when a large amount of data (around 3.5 GB or larger) is being written to a DVD-R. The wodim 1.11 (there seem to be no problems with older versions of wodim such as v1.9) and genisoimage packages from the cdrkit (or one of their dependencies) used by Debian-based distributions (including (K)Ubuntu) may be dysfunctional and may generate a message similar to "cdrecord error 254" error while burning using K3B. Alternately, any file(s) written above the 3.5 GB limit may be improperly written to DVD.
- This effectively limits DVD-R burning to less than 3.5 GB. One suggested solution entails installing a current copy of cdrtools manually. One location for obtaining cdrtools .deb packages is this Launchpad PPA repository. Download and install the cdrecord .deb package for your OS type (i386 or amd64). mkisofs and cdda2wav should be installed as well, as indicated here.
- Solution: Do not use the cdrecord (which includes wodim) for writing DVD disks that contain more than 3.5 Gb data. Instead, use growisofs:
- k3b -> Burn -> Writing app: growisofs -> Writing mode: DAO
- this has successfully allowed me to burn DVDs with more than 3.5 Gb data.
- Alternatively, obtain and use the older version of k3b/cdrecord/wodim (v1.9), such as used in the Lucid Lynx. This is not an easy solution to implement other than by installing a standalone Lucid Lynx OS in its own small partition.
Cdrecord has no permission to open the device error
If you receive the "cdrecord has no permission to open the device" error while burning using K3B, open a terminal and type:
sudo chmod 777 /dev/scd0
- Note: replace /dev/scd0 with your own device, e.g. /dev/sr0.
- Note: chmod 777 is the universal option for granting full permission to a folder. The 777 mask indicates that read, write, and execute permission is given to all users.
DVD Playback Capability
To play encrypted DVDs, the libdvdcss2 package is essential. libdvdcss2 is a simple library designed for accessing DVDs like a block device without having to bother about the decryption. More information about this package can be found at VideoLAN.
- You can install libdvdcss2 as a 64-bit .deb package without installing the Medibuntu repositories:
wget -c http://packages.medibuntu.org/pool/free/libd/libdvdcss/libdvdcss2_1.2.10-0.3medibuntu1_amd64.deb sudo dpkg -i libdvdcss2_1.2.10-0.3medibuntu1_amd64.deb
- or a 32-bit .deb package:
wget -c http://packages.medibuntu.org/pool/free/libd/libdvdcss/libdvdcss2_1.2.10-0.3medibuntu1_i386.deb sudo dpkg -i libdvdcss2_1.2.10-0.3medibuntu1_i386.deb
- You can also use guidelines provided at Medibuntu. This will install the Medibuntu repositories on your system and then install the libdvdcss2 package:
sudo wget --output-document=/etc/apt/sources.list.d/medibuntu.list http://www.medibuntu.org/sources.list.d/$(lsb_release -cs).list sudo apt-get update sudo apt-get --yes --allow-unauthenticated install medibuntu-keyring sudo apt-get update sudo apt-get install libdvdcss2
- You can also install 32 bit or 64 bit Windows multimedia codecs (if you haven't already done so using ubuntu-restricted-extras):
sudo apt-get install w32codecs
sudo apt-get install w64codecs
- Instead of downloading directly from Medibuntu, you could also use the script included with the libdvdread4 package to download and install libdvdcss2:
sudo apt-get install libdvdread4 sudo /usr/share/doc/libdvdread4/install-css.sh
Many newer DVDs use the UDF filesystem. To play them properly, also install libudf:
sudo apt-get install libudf0
Other tools are useful:
sudo apt-get install udftools libudf-dev
K9copy (DVD Ripper)
K9copy is the free open source DVD backup, copying, compression, and authoring utility that requires libdvdcss. For other info, see this or this guide. You can easily create MPEG-2. MPEG-4, or DVD videos with this utility.
sudo apt-get install k9copy
- See this section for tips on using k9copy with mencoder and NTFS DVDs.
- Tips: At times you may not be able to copy your DVD directly from DVD to DVD. This may because you have a small imperfection in the DVD, or because the DVD was initially created with a non-standard burning method. There are two methods that can help solve this problem:
- Copy the VIDEO_TS and AUDIO_TS folders from your original DVD directly to your hard drive. Then use k9copy to burn a DVD directly from these hard drive folders.
- Use k3b (or Gnomebaker) to copy an .iso image from the original DVD to your hard drive. Then use k9copy to extract from the hard drive .iso image and then burn a DVD directly from it.
Handbrake is a GPL-licensed open source tool for converting DVD to MPEG-4 (iPod format) that is an alternative to k9copy. (It can handle many DVDs that k9copy cannot.) Note that Handbrake supports X264/H.264 and MP4 encoding but no longer supports the XVID video codec. It uses the .MP4/.M4V or .MKV containers, but no longer supports the .AVI container. However, it uses a streaming algorithm that (while slower than other methods) is compatible with a large variety of encryption techniques. (Following "ripping" from a DVD, the resulting .MP4 or .MKV file can be converted to other formats, such as .AVI with XVID, using these suggestions.) Installation is from the developmental PPA archive.
sudo add-apt-repository ppa:stebbins/handbrake-releases sudo apt-get update sudo apt-get install handbrake-gtk handbrake-cli
If you do not intend to use the command-line interface, you can skip handbrake-cli.
- Alternatively, to your package manager you can add the custom repository:
deb http://ppa.launchpad.net/stebbins/handbrake-releases/ubuntu oneiric main
then install the package handbrake-gtk (and handbrake-cli if desired).
dvd::rip is a DVD backup/copy program, written in GTK-based perl, that uses the transcode and ffmpeg video/audio processing and conversion tools. See the website for installation and official documentation. For other info, see this dvd::rip tutorial. Install:
sudo apt-get install dvdrip rar
Acidrip is a DVD backup/copy program, written in GTK-based perl, that uses the Mplayer and Mencoder video/audio processing and conversion tools (and therefore yields the best quality DVD rips to an .AVI file with XVID video, for example). See the website for installation and official documentation. Install:
sudo apt-get install acidrip
DVD Fab (DVD Ripper)
DVD Fab is the favoured DVD backup tool for today's DVD encryption methods. It must be run in Wine (since it is a Windows application). It comes as a fully featured 30-day trial, but see these instructions for fine-tuning the trial period.
