Thema: FFmpeg-Projekt vermeldet Fortschritte

[SiLæncer]

Das FFmpeg-Projekt hat sein Multimedia-Framework in der Version 2.0 veröffentlicht. FFmpeg ermöglicht es Anwendern, nahezu alle Multimediaformate zu enkodieren, dekodieren oder transkodieren, zu streamen, durch Filter und Multiplexer zu schicken und abzuspielen.

FFmpeg enthält die Multimedia-Bibliotheken libavcodec, libavutil, libavformat, libavfilter, libavdevice, libswscale und libswresample, die Entwickler in eigenen Anwendungen nutzen können sowie die für Endbenutzer gedachten Programme ffmpeg, ffserver, ffplay und ffprobe. FFmpeg 2.0 unterstützt OpenCL und den verlustfreien Audio-Kompressor Monkey's Audio. Das Framework wurde um eine große Anzahl neuer Filter erweitert. Dazu zählen beispielsweise Filter um Kurven zu zeichnen, Rauschen zu mindern, Farben zu beeinflussen, Filme optisch abzutasten oder Ebenen zu kombinieren. Die Syntax für Filteroptionen wurde für alle Filter vereinheitlicht. Die Zeitachse eines Videos oder einer Audiodatei lässt sich nun mit Filtern bearbeiten.

Die Multimedia-Bibliothek FFmpeg unterstützt nun auch den Video-Kompressionsstandard H.265 alias HEVC. Damit stehen mehrere freie Implementierungen des Standards bereit.

Seit einigen Wochen ist in den Git-Quellen des VLC-Players ein De- und Encoder für den Video-Kompressionsstandard H.265 alias High Efficiency Video Coding (HEVC) verfügbar. Auch die freie Multimedia-Bibliothek FFmpeg unterstützt jetzt den neuen Videostandard, wie aus einer Nachricht auf Launchpad hervorgeht.
