Der freie Mediaplayer VLC media player ist nach längerer Entwicklungszeit, die auch durch die Umstellung der Lizenz von GPLv2+ auf LGPLv2.1+ bedingt war, endlich in der Version 2.0 "Twoflower" erschienen, mit der nicht nur eine Vielzahl an Bugs behoben, sondern auch jede Menge Änderungen am Code vorgenommen und neue Features implementiert wurden. Zu den wichtigsten Neuerungen gehört die Unterstützung von ungeschützten Blu-ray-Discs (noch experimentell), skalierbare Untertitel sowie eine neue Oberfläche unter Mac OS X. Darüber hinaus bietet die neue Version eine ganze Reihe von Optionen, mit denen sich das Verhalten sowie die Größe des Caches konfigurieren lassen. Zu guter Letzt soll es künftig eine 64-Bit-Version des Mediaplayers geben.
Das Programm unterstützt bereits von Haus aus unzählige Audio- und Video-Codecs und wird für eine Vielzahl unterschiedlicher Betriebssysteme bereitgestellt. Eine Übersicht der bereits integrierten Codecs und der unterstützten Plattformen zeigt die Feature-Übersicht. Der VLC media player wird als Freie Software unter der GNU Lesser General Public License, Version 2.1 angeboten. Der Player hebt sich von vielen anderen Programmen unter anderem dadurch hervor, dass er auch unvollständige oder gar noch im Download befindliche Videodateien abspielen kann.
Zu den neuen Funktionen seit Version 1.1.0 zählte u.a. die Unterstützung für GPU Decoding unter Windows Vista bzw. Windows 7 sowie unter Linux. Allerdings bedauerte man anfangs, dass man unter Windows die Verwendung von NVIDIA GPUs empfehlen musste, da die Treiber für ATI GPUs einen Fehler beinhalten sollen und man leider keine passende Hardware zur Verfügung hat, um Decoding auf Intel GPUs zu unterstützen.
Kurz nach dem Erscheinen kündigte man dann aber an, dass auch die ATI GPUs ab der ATI Radeon 4000 Serie nach einem Treiberupdate auf den mittlerweile erschienenen ATI Catalyst 10.7 ab Version 1.1.1 des VLC media player in den Genuss der GPU-Beschleunigung kommen. Dazu arbeitete man mit den Treiberentwicklern bei AMD eng zusammen.
Seit der Version 1.1.5 kommen endlich auch die Besitzer einer Intel IGP in den Genuss von Hardwarebeschleunigung der Videodekodierung unter Windows.
Windows wird ab Windows XP SP2 und Mac OS X wird ab der Version 10.5 unterstützt.
Was ist neu?
Changes between 1.1.13 and 2.0.0:
Important notes:
The licenses of libVLC and libVLCcore have changed from GPLv2+ to LGPLv2.1+
Start/end titles/chapters are now specified with # rather than @ to fix conflicts with some URLs and file names. For instance, this plays a DVD from the 2nd chapter of the 1st title up to the 4th chapter of the 3rd title: vlc dvd://#1:2-3:4
The 40+ --*-caching options were simplified and dumbed down to 4 options: - --file-caching specifies caching for local files, - --network-caching specifies caching for network resources, - --live-caching specifies caching for capture devices and - --disc-caching specifies caching for local optical media. All values are expressed in milliseconds as in previous versions.
HTTP server IP address, port, and TLS configuration is now centralized: - The --http-host option sets the address, e.g. "--http-host=[2001:db8::1]". By default, both :: and 0.0.0.0 are used. - The --http-port and --https-port options set the port numbers. By default, 8080 is used for HTTP, and 8443 for HTTPS. - The TLS credentials are configured with --http-cert (public certificate), --http-key (private key), --http-ca (optional CA) and --http-crl (optional CRL).
RTSP server IP address and port are updated similarly. Use --rtsp-host and --rtsp-port respectively.
The --miface-addr option does not exist anymore. To select the multicast output interface, use --miface instead, e.g. --miface=eth0.
The Windows version will only work with Windows XP SP2 or later. Windows 2000 SP4, Windows XP < SP2, Windows 2003 SP0 are now unsupported.
The Mac OS version will require Quartz Extreme compatible machines.
Important changes for packagers:
The default builds now assume that the operating system uses UTF-8 for its file systems and files content (except the Windows port). If this is not acceptable, pass --enable-non-utf8 to the configure script. Non-UTF-8 file systems support will be removed in future versions.
The VLC plugins path can be overridden with the VLC_PLUGIN_PATH environment variable. The --plugin-path command line option was removed.
The default tarballs are now compressed with XZ/LZMA: .tar.xz
OSS support is not compiled on Linux by default, pass --enable-oss to the configure script if you use OSSv4 or really want to use OSS emulation.
The webplugins have moved to: git://git.videolan.org/npapi-vlc.git
