From b3b820fc9b2b9d41009b36448b75d974755d7cd2 Mon Sep 17 00:00:00 2001 From: fujunwei Date: Tue, 17 May 2016 09:18:27 +0800 Subject: [PATCH] [Android] Support third part media player on Crosswalk A requirement from an important customer who want to forward web resources with proxy on Crosswalk, but android system MediaPlayer can't set a proxy with a standard API. The ExoMediaPlayer is playing videos and music is a popular activity on Android devices, and it can be configured with proxy. https://developer.android.com/guide/topics/media/exoplayer.html BUG=XWALK-6770 --- .../src/org/chromium/media/ExMediaPlayer.java | 123 ++++++++++++++++++ .../org/chromium/media/MediaPlayerBridge.java | 71 +++++----- 2 files changed, 162 insertions(+), 32 deletions(-) create mode 100644 media/base/android/java/src/org/chromium/media/ExMediaPlayer.java diff --git a/media/base/android/java/src/org/chromium/media/ExMediaPlayer.java b/media/base/android/java/src/org/chromium/media/ExMediaPlayer.java new file mode 100644 index 0000000000000..cb01cf62d67f2 --- /dev/null +++ b/media/base/android/java/src/org/chromium/media/ExMediaPlayer.java @@ -0,0 +1,123 @@ +// Copyright 2013 The Chromium Authors.
