From 89e1e7fcbcbe93d8096afe0f7c240fe706cc9069 Mon Sep 17 00:00:00 2001 From: Gareth Stockwell Date: Wed, 2 Dec 2009 16:20:00 +0000 Subject: Implemented support for playlist handling in Phonon MMF backend The main changes are: 1. MediaObject emits prefinishMark at the appropriate instant 2. MediaObject emits aboutToFinish at the appropriate instant 3. MediaObject switches to next source when playback completes Task-number: QTBUG-6214 Reviewed-by: Frans Englich --- src/3rdparty/phonon/mmf/abstractmediaplayer.cpp | 84 ++++++++++++++----------- src/3rdparty/phonon/mmf/abstractmediaplayer.h | 17 ++--- src/3rdparty/phonon/mmf/abstractplayer.cpp | 22 +++---- src/3rdparty/phonon/mmf/abstractplayer.h | 13 ++-- src/3rdparty/phonon/mmf/audioplayer.cpp | 41 +++--------- src/3rdparty/phonon/mmf/audioplayer.h | 5 +- src/3rdparty/phonon/mmf/dummyplayer.cpp | 19 +----- src/3rdparty/phonon/mmf/dummyplayer.h | 8 +-- src/3rdparty/phonon/mmf/mediaobject.cpp | 54 +++++++++------- src/3rdparty/phonon/mmf/mediaobject.h | 11 +++- src/3rdparty/phonon/mmf/mmf_videoplayer.cpp | 22 ++----- src/3rdparty/phonon/mmf/mmf_videoplayer.h | 3 +- 12 files changed, 129 insertions(+), 170 deletions(-) diff --git a/src/3rdparty/phonon/mmf/abstractmediaplayer.cpp b/src/3rdparty/phonon/mmf/abstractmediaplayer.cpp index 83c534a..18f96cc 100644 --- a/src/3rdparty/phonon/mmf/abstractmediaplayer.cpp +++ b/src/3rdparty/phonon/mmf/abstractmediaplayer.cpp @@ -20,6 +20,7 @@ along with this library.
