Bits from the Debian Multimedia Maintainers

6

This brief announcement was released yesterday to the debian-devel-announce mailing list.

 

Ciao!

The Debian Multimedia Maintainers have been quite active since the Wheezy release, and have some interesting news to share for the Jessie release. Here we give you a brief update on what work has been done and work that is still ongoing.

Let’s see what’s cooking for Jessie then.

 

Frameworks and libraries

Support for many new media formats and codecs.

The codec library libavcodec, which is used by popular media playback applications including vlc, mpv, totem (using gstreamer1.0-libav), xine, and many more, has been updated to the latest upstream release version 11 provided by Libav. This provides Debian users with HEVC playback, a native Opus decoder, Matroska 3D support, Apple ProRes, and much more. Please see libav’s changelog for a full list of functionality additions and updates.

libebur128

libebur128 is a free implementation of the European Broadcasting Union Loudness Recommendation (EBU R128), which is essentially an alternative to ReplayGain. The library can be used to analyze audio perceived loudness and subsequentially normalize the volume during playback.

libltc

libltc provides functionalities to encode and decode Linear (or Longitudinal) Timecode (LTC) from/to SMPTE data timecode.

libva

libva and the driver for Intel GPUs has been updated to the 1.4.0 release. Support for new GPUs has been added. libva now also supports Wayland.

Pure Data

A number of new additional libraries (externals) will appear in Jessie, including (among others) Eric Lyon’s fftease and lyonpotpourrie, Thomas Musil’s iemlib, the pdstring library for string manipulation and pd-lua that allows to write Pd-objects in the popular lua scripting language.

 

JACK and LADI

LASH Audio Session Handler was abandoned upstream a long time ago in favor of the new session management system, called ladish (LADI Session Handler). ladish allows users to run many JACK applications at once and save/restore their configuration with few mouse clicks.

The current status of the integration between the session handler and JACK may be summarized as follows:

  • ladish provides the backend;
  • laditools contains a number of useful graphical tools to tune the session management system’s whole configuration (including JACK);
  • gladish provides a easy-to-use graphical interface for the session handler.

Note that ladish uses the D-Bus interface to the jack daemon, therefore only Jessie’s jackd2 provides support for and also cooperates fine with it.

 

Plugins: LV2 and LADSPA

Debian Jessie will bring the newest 1.10.0 version of the LV2 technology. Most changes affect the packaging of new plugins and extensions, a brief list of packaging guidelines is now available.
A number of new plugins and development tools too have been made available during the Jessie development cycle:

LV2 Toolkit

LVTK provides libraries that wrap the LV2 C API and extensions into easy to use C++ classes. The original work for this was mostly done by Lars Luthman in lv2-c++-tools.

Vee One Suite

The whole suite by Rui Nuno Capela is now available in Jessie, and consists of three components:

  • drumkv1: old-school drum-kit sampler synthesizer
  • samplv1: polyphonic sampler
  • synthv1: analog-style 4-oscillator substractive synthesizer

All three are provided in both forms of LV2 plugins and stand-alone JACK client. JACK session, JACK MIDI, and ALSA MIDI are supported too.

x42-plugins and zam-plugins

LV2 bundles containing many audio plugins for high quality processing.

Fomp

Fomp is an LV2 port of the MCP, VCO, FIL, and WAH plugins by Fons Adriaensen.

Some other components have been upgraded to more recent upstream versions:

  • ab2gate: 1.1.7
  • calf: 0.0.19+git20140915+5de5da28
  • eq10q: 2.0~beta5.1
  • NASPRO: 0.5.1

We’ve packaged ste-plugins, Fons Adriaensen’s new stereo LADSPA plugins bundle.

A major upgrade of frei0r, namely the standard collection for the minimalistic plugin API for video effects, will be available in Jessie.

 

New multimedia applications

Advene

Advene (Annotate Digital Video, Exchange on the NEt) is a flexible video
annotation application.

Ardour3

The new generation of the popular digital audio workstation will make its very first appearance in Debian Jessie.

Cantata

Qt4 front-end for the MPD daemon.

Csound

Csound for jessie will feature the new major series 6, with the improved IDE CsoundQT. This new csound supports improved array data type handling, multi-core rendering and debugging features.

din

DIN Is Noise is a musical instrument and audio synthesizer that supports JACK audio output, MIDI, OSC, and IRC bot as input sources. It could be extended and customized with Tcl scripts too.

dvd-slideshow

dvd-slideshow consists of a suite of command line tools which come in handy to make slideshows from collections of pictures. Documentation is provided and available in `/usr/share/doc/dvd-slideshow/’.

dvdwizard

DVDwizard can fully automate the creation of DVD-Video filesystem. It supports graphical menus, chapters, multiple titlesets and multi-language streams. It supports both PAL and NTSC video modes too.

flowblade

Flowblade is a video editor – like the popular KDenlive based on the MLT engine, but more lightweight and with some difference in editing concepts.

forked-daapd

Forked-daapd switched to a new, active upstream again dropping Grand Central Dispatch in favor of libevent. The switch fixed several bugs and made forked-daapd available on all release architectures instead of shipping only on amd64 and i386. Now nothing prevents you from setting up a music streaming (DAAP/DACP) server on your favorite home server no matter if it is based on mips, arm or x86!

harvid

HTTP Ardour Video Daemon decodes still images from movie files and serves them via HTTP. It provides frame-accurate decoding and is main use-case is to act as backend and second level cache for rendering the
videotimeline in Ardour.

Groove Basin

Groove Basin is a music player server with a web-based user interface inspired by Amarok 1.4. It runs on a server optionally connected to speakers. Guests can control the music player by connecting with a laptop, tablet, or smart phone. Further, users can stream their music libraries remotely.
It comes with a fast, responsive web interface that supports keyboard shortcuts and drag drop. It also provides the ability to upload songs, download songs, and import songs by URL, including YouTube URLs. Groove Basin supports Dynamic Mode which automatically queues random songs, favoring songs that have not been queued recently.
It automatically performs ReplayGain scanning on every song using the EBU R128 loudness standard, and automatically switches between track and album mode. Groove Basin supports the MPD protocol, which means it is compatible with MPD clients. There is also a more powerful Groove Basin protocol which you can use if the MPD protocol does not meet your needs.

HandBrake

HandBrake, a versatile video transcoder, is now available for Jessie. It could convert video from nearly any format to a wide range of commonly supported codecs.

jack-midi-clock

New jackd midiclock utility made by Robin Gareus.

laborejo

Laborejo, Esperanto for “Workshop”, is used to craft music through notation. It is a LilyPond GUI frontend, a MIDI creator and a tool collection to inspire and help music composers.

mpv

mpv is a movie player based on MPlayer and mplayer2. It supports a wide variety of video file formats, audio and video codecs, and subtitle types. The project focuses mainly on modern systems and encourages developer activity. As such, large portions of outdated code originating from MPlayer have been removed, and many new features and improvements have been added. Note that, although there are still some similarities to its predecessors, mpv should be considered a completely different program (e.g. lacking compatibility with both mplayer and mplayer2 in terms of command-line arguments and configuration).

smtube

SMTube is a stand-alone graphical video browser and player, which makes YouTube’s videos browsing, playing, and download such a piece of cake.
It has so many features that, we are sure, will make YouTube lovers very, very happy.

sonic-visualiser

Sonic Visualiser Application for viewing and analysing the contents of music audio files.

SoundScapeRenderer

SoundScapeRenderer (aka SSR) is a (rather) easy to use render engine for spatial audio, that provides a number of different rendering algorithms, ranging from binaural (headphone) playback via wave field synthesis to higher-order ambisonics.

Videotrans

videotrans is a set of scripts that allow its user to reformat existing movies into the VOB format that is used on DVDs.

XBMC

XBMC has been partially rebranded as XBMC from Debian to make it clear that it is changed to conform to Debian’s Policy. The latest stable release, 13.2 Gotham will be part of Jessie making Debian a good choice for HTPC-s.

zita-bls1

Binaural stereo signals converter made by Fons Adriaensen

zita-mu1

Stereo monitoring organiser for jackd made by Fons Adriaensen

zita-njbridge

Jack clients to transmit multichannel audio over a local IP network made by Fons Adriaensen

radium-compressor

Radium Compressor is the system compressor of the Radium suite. It is provided in the form of stand-alone JACK application.

What’s not going to be in Jessie

With the aim to improve the overall quality of the multimedia software available in Debian, we have dropped a number of packages which were abandoned upstream:

  • beast
  • flumotion
  • jack-rack
  • jokosher
  • lv2fil (suggested replacement for users is eq10q or calf eq)
  • phat
  • plotmm
  • specimen (suggested replacement for users is petri-foo – fork of specimen)
  • zynjacku (suggested replacement for users is jalv)

We’ve also dropped mplayer, presently nobody seems interested in maintaining it.
The suggested replacements for users are mplayer2 or mpv. Whilst the former is mostly compatible with mplayer in terms of command-line arguments and configuration (and adds a few new features too), the latter adds a lot of new features and improvements, and it is actively maintained upstream.

Please note that although the mencoder package is no longer available anymore, avconv and mpv do provide encoding functionality. For more information see avconv’s manual page and documentation, and mpv’s encoding documentation.

 

Broken functionalities

rtkit under systemd is broken at the moment.

 

Activity statistics

More information about team’s activity are available.

 

Where to reach us

The Debian Multimedia Maintainers can be reached at pkg-multimedia-maintainers AT lists.alioth.debian.org for packaging related topics, or at debian-multimedia AT lists.debian.org for user and more general discussion.
We would like to invite everyone interested in multimedia to join us there. Some of the team members are also in the #debian-multimedia channel on OFTC.

Cheers!

Be right back soon

Some days ago I moved to Aberdeen, Scotland, and I’m still experiencing some issues with my Internet connection, so I’m not yet able to come back to work on packaging stuff as usual.

So please, have some patience, I’ll be right back soon :)

LADI Tools: first stable release is out!

0

During the last month I worked as upstream maintainer of LADI Tools and now I’m happy to introduce the first stable release! So, to answer the usual question “What’s new?”, here is a short description of the changes introduced (taken from the NEWS file included in the release tarball):

Laditools 1.0 «Lady “O”»

Apart from wladi and g15ladi, most of ladi* tools have been renamed:

  • ladicontrol -> ladi-control-center
  • ladilog -> ladi-system-log
  • laditray -> ladi-system-tray

Moreover, a new component has joined the LADI Tools suite: ladi-player. LADI Player is a convenient, graphical VLC-style application providing an all-in-one control interface to start, stop and monitor JACK as well as the session handler. It also provides basic controls for managing studios.

Goodbye PyGTK!

All the code was ported to GTK+ 3 and the new GObject Introspection mechanism.

Code refactoring and cleanup

The code has been reorganized in order to allow the use of Python objects by 3rd party applications.

To start writing code using the classes provided by laditools, simply do the following:

from laditools import *

Two-in-one solution for LADI System Tray

Formerly laditray was an implementation of GtkStatusIcon to put a nice right-clickable icon into the system tray to allow users access JACK controls easy way. It’s been mostly rewritten and now it shows an AppIndicator icon (if the library is available), or fall back to the Freedesktop.org’s old-fashioned System Tray Protocol Spec-compliant icon.

Project’s new homepage

The project’s homepage is now hosted by Launchpad.net, the code is hosted by repo.or.cz and it’s available here for browsing.
Please use the following links to contact the development team:

New up-to-date packages will hit both Debian and Ubuntu soon!

To tablet or not to tablet, to tablet or not to tablet, to tablet or…

Well, I’ve found the answer :)

Bits from the Debian Multimedia Maintainers

This brief announcement was published in the debian-devel-announce mailing list and I repeat it here for your information.

Hi!

Since there has been a lot happening in the Debian Multimedia world during the Squeeze release, so we figured we should give you an update on that.

Who are we?

In the dark old ages, there were two teams involved in multimedia: the Debian Multimedia and Debian Multimedia Packages teams. Please note that neither of them is related to debian-multimedia.org (which is maintained by Christian Marillat, and is known to break current ffmpeg-based applications like mplayer and vlc in Debian Squeeze.). During late 2008, both teams were merged into one, the Debian Multimedia Maintainers team, to avoid effort fragmentation. Since then, there has been a lot of work done:

Consumer Multimedia in Debian

Consumer Multimedia is about playing and, well, consuming multimedia.

Squeeze will feature:

  • FFmpeg 0.5.2, finally uncrippled thanks to zack! No mp3/h264 encoder, though. (still in NEW).
  • mplayer 1.0rc3, finally with mencoder enabled.
  • VLC 1.1.3
  • VDPAU hardware acceleration in ffmpeg/mplayer (but feedback is welcome!)
  • Guayadeque 0.2.5
  • gmusicbrowser 1.0.2

Squeeze will not feature:

  • FFmpeg 0.6 (But already available in experimental)
  • Hardware acceleration with VA-API (packages also in experimental, for support on Intel hardware).

Producer Multimedia in Debian

Producer multimedia is software for producing multimedia. Squeeze will
feature:

End user applications:

  • Ardour 2.8.11
  • Audacity 1.3.12
  • Composite 0.006
  • Csound 5.12. The QuteCsound frontend is also available.
  • FluidSynth 1.1.1
  • Hydrogen 0.9.4.1
  • Internet DJ Console 0.8.3
  • Jokosher 0.11.5
  • LiVES 1.3.4
  • mhWaveEdit 1.4.20
  • morituri 0.1.1
  • QTractor 0.4.6
  • Rosegarden 10.04.2
  • SooperLooper 1.6.14
  • Traverso 0.49.1
  • X Jack Video Monitor 0.4.13
  • Yoshimi 0.058.1

Platforms and technologies:

  • JACK versions 0.118 and 1.9.6 (aka, jackd1 and jackd2). You can choose to install any of them (but only one at a time).
  • LV2 plugins are supported. Ardour has support for them, and there are a bunch of them provided in Debian.
  • LADSPA plugins are still supported.
  • DSSI updated to 1.0.0, many plugins are available.
  • FireWire sound devices are supported with libffado, and is supported by JACK.

Squeeze will not feature:

  • JACK session support.
  • Ardour 3 (it’s not out yet, so it did not make it in time for squeeze).
  • SuperCollider. There is a package in the works, but did not make it to Squeeze.
  • Toonloop: This live stop-motion animation editor has been packaged only recently.
  • NASPRO: Convenient library to implement LV2 dynamic manifest plugins. It’s available in Sid.
  • Mixxx: 1.7 series had RC bugs, and 1.8 was too late for squeeze.

Debian Multimedia Blend

There is also an effort to start a Debian Multimedia Blend to give a better overview about what multimedia applications are available in Debian. There is a short list for a quick overview as well as a long package list separated in sections to give a more detailed overview (including translations, screenshots, popularity of package etc). You are invited to help improving the tasks either directly in SVN or by sending patches to Andreas Tille <tille@debian.org> or debian-multimedia@lists.debian.org (see below). Note that not all of the packages listed in the tasks pages are maintained by the Debian Multimedia team, since they are aimed at producing useful package sets instead of showing only our own packages.

For those who want to squash some bugs in multimedia packages there is also the bugs page generated by the Blends tools, or our team bug page.

Other activity

The team has seen a lot of growth since the merger. Of the current 52 members of the Alioth team, 20 were added during 2009 and 18 in 2010, many of whom are involved in upstream development as well as the debian packaging. The number of packages has also grown, with 112 of the current 205 git repositories in our team area having its first commit during 2010.

Where to reach us

The Debian Multimedia Maintainers can be reached at pkg-multimedia-maintainers@lists.alioth.debian.org, should you have any questions. We have also decided to repurpose the old debian-multimedia@lists.debian.org address for user and more general discussion. We would like to invite everyone interested in multimedia to join us there. Interested developers/packagers can also join us at the first address. Some of the team members are also in the #debian-multimedia channel on OFTC.

Regards,

Alessio Treglia on behalf of the Debian Multimedia Maintainers

Manage your font collection with Font Manager

13

Already available in both Maverick and Debian sid, it provides many interesting features.

I’m talkin’ about Font Manager, a small application written in C and Python by Jerry Casiano, which allows users to easily install, remove and compare font files on own system.

Here are few nice screenshots:

To install the application, as usual type:

sudo apt-get install font-manager

Let me know what you think! ;)

What a beautiful day

0

I have two nice news to tell you today!

  1. Nautilus Pastebin has been entered Debian’s unstable archive (PTS page).
  2. Yesterday morning I opened my mailbox and the first email began with the following:

    Hi,

    Congratulations! This e-mail confirms that Canonical would like to offer you sponsorship in the form of accommodation and travel to the Ubuntu Developers Summit in Dallas for the Ubuntu 10.04 Lucid Lynx release – http://wiki.ubuntu.com/UDS

I can’t describe what I feel, I just want to thank Canonical for giving me this opportunity.

Nautilus Pastebin, how to send your files to a “pastebin” with one mouse click

5

I am very fond of those websites that allow users to upload files for a public viewing (called pastebin), usually I upload logs, links and other text files with pastebinit, a simple command-line tool, already available in Debian’s and Ubuntu’s archives, and I thought:

“Why don’t find a not-CLI solution to make it in a more fast and comfortable way?”

So I decided to write nautilus-pastebin, an extension for the GNOME file manager, which allows users to send files just a right-click away.

How does it work?

Simply: right-click on a file, select «Pastebin» and, if the Internet connection is active, after few seconds you will see a bubble like that one in this screenshot:

The extension doesn’t only show that notification, it also retrieves the MIME type in order to try to adjust the syntax highlighting parameter according to the configuration of the selected pastebin and finally copies the paste URL to the clipboard, allowing you to paste it in a browser tab, IRC channel or wherever you want.

The global configuration file is located into /etc path, but if you want to select another pastebin to use you may do it by creating a file like the following one:

[generals]
pastebin = $GLOBAL_CONFIGFILE_SECTION

The file must be named as nautilus-pastebin.conf and saved under ~/.config/nautilus-pastebin/.

If problems occured during the past operation, you may see a message like the following:

Where can I download it? And how can install it?

You can find all the information that you need by opening the projects page, for the installation, after uncompressing the tarball, you can:

  1. Use the setup.py script.
  2. Copy:
    1. scripts/nautilus-pastebin.py to /usr/lib/nautilus/extensions-2.0/python/
    2. data/nautilus-pastebin.conf to /etc/ or in ~/.config/nautilus-pastebin/
    3. data/nautilus-pastebin.png to /usr/share/pixmaps/

After the installation, you may need to restart Nautilus:

killall nautilus

Some pastebins of the preconfigured ones don’t work well and I need some time to improve and extend the support for other websites.

If you wanted to contribute to the development by sending me patches, configurations or suggestions I would be very happy!

Ubuntu Customization Kit, welcome to the Universe!

2

As you could see, yesterday Ubuntu Customization Kit has been entered in to the Universe repository.

I want to give a special thanks! to Luca Falavigna for all the support (and for the upload too).

Installation Report Generator 0.2.0 is out!

0

In the last period I have no spare time to write something of interesting (:D), I just want to announce new release of Installation Report Generator 0.2 (available in Jaunty), which provides new plugin support.

For further informations, the ChangeLog is available here.
