PLDroidPlayer
PLDroidPlayer ist ein Android-Video-Player-SDK und ein anpassbares Media-Playback-Framework. Es bietet eine plattformübergreifende Media-Engine und einen hardwarebeschleunigten Videodecoder, der mehrere Hardwarearchitekturen unterstützt und einen automatischen Fallback auf Softwareverarbeitung beinhaltet.
Das Projekt fungiert als netzwerkoptimierter Streaming-Client mit benutzerdefinierter DNS-Auflösung und automatischer Latenzoptimierung, um die Verzögerung bei Live-Übertragungen zu reduzieren. Es enthält spezialisierte Funktionen für die sichere Wiedergabe verschlüsselter Videostreams unter Verwendung spezifischer Provider-Protokolle.
Das Framework deckt ein breites Spektrum an Wiedergabe- und Rendering-Funktionen ab, einschließlich der Extraktion roher dekodierter Daten, Hintergrund-Audiowiedergabe und Audio-Lautstärkeverstärkung. Es bietet zudem Tools für die Videobildmanipulation wie Spiegelung, Rotation, Rendering von Teilbereichen und Screenshot-Aufnahme, unterstützt durch lokales Video-Caching und Beschleunigung des Stream-Ladens.
Features
