+
+1. android_frameworks_native:
+https://github.com/omxcodec/android_frameworks_native.git
+branch: cm_maguro-10.1
+
+2. android_frameworks_av:
+https://github.com/omxcodec/android_frameworks_av.git
+branch: cm_maguro-10.1
+
+3. android_external_ffmpeg
+git@github.com:omxcodec/android_external_ffmpeg
+branch: cm_maguro-10.1

+How to build
+================================================================================
+
+1. Get the Source
+ in your "android/external" folder, run:
+ stagefright-plugins(branch: master):
+ git clone git@github.com:omxcodec/stagefright-plugins.git stagefright-plugins
+ ffmpeg(branch: cm_maguro-10.1):
+ git clone git@github.com:omxcodec/android_external_ffmpeg.git ffmpeg -b cm_maguro-10.1
+
+ android_frameworks_native and android_frameworks_av:
+ you should merge my android_frameworks_native(branch: cm_maguro-10.1) and
+ android_frameworks_av(branch: cm_maguro-10.1) code. once you do, you should pay attention to
+ the "USES_NAM" flag, it is only in the "android/frameworks/native" and "android/frameworks/av"
+ directories.
+
+2. Compile
+ add USES_NAM flag to COMMON_GLOBAL_CFLAGS in your android build system(e.g. my device: maguro)
+ vi vendor/samsung/maguro/BoardConfigVendor.mk and add this line to it
+ COMMON_GLOBAL_CFLAGS += -DUSES_NAM
+ then compile your android source tree again!
+
+3. Install
+ adb root
+ adb remount
+ adb sync // sync your android build system to your phone or pad
+ reboot // reboot your phone or pad
+
+4. Run
+ get test media files:
+ wget http://movies.apple.com/media/us/ipad/2012/tv-spots/apple-ipad-this_good-us-20120307_848x480.mov
+ wget http://movies.apple.com/media/us/ipad/2012/80ba527a-1a34-4f70-aae8-14f87ab76eea/tours/apple-ipad-feature-us-20120307_848x480.mp4
+ wget http://ftp.kw.bbc.co.uk/hevc/hm-10.0-anchors/bitstreams/i_main/BQMall_832x480_60_qp22.bin
+
+ let us suppose your media files locate at "/sdcard/Movies/" folder.
+ one console window, you should run:
+ adb logcat -c //clears (flushes) the entire log and exits.
+ adb logcat
+ and other cosole window, you should run:
+ test FFmpegExtractor plugins:
+ adb shell am start -a android.intent.action.VIEW -d file:///mnt/sdcard/Movies/apple-ipad-this_good-us-20120307_848x480.mov -t video/*
+ adb shell am start -a android.intent.action.VIEW -d file:///mnt/sdcard/Movies/apple-ipad-feature-us-20120307_848x480.mp4 -t video/*
+ test SoftFFmpegVideo decoder plugin:
+ cd android/external/stagefright-plugins/tools folder, run:
+ adb root
+ ./install // install my scripts
+ adb root && adb shell set-vdec-sw1 // let omxcodec choose software decoder
+ adb shell am start -a android.intent.action.VIEW -d file:///mnt/sdcard/Movies/apple-ipad-this_good-us-20120307_848x480.mov -t video/*
+ adb shell am start -a android.intent.action.VIEW -d file:///mnt/sdcard/Movies/apple-ipad-feature-us-20120307_848x480.mp4 -t video/*
+
+ test HEVC(H.265) decoder:
+ cd android/external/stagefright-plugins/tools folder, run:
+ adb root
+ ./install // install my scripts
+ adb root && adb shell set-vdec-drop // disable drop video frames
+ adb shell am start -a android.intent.action.VIEW -d file:///mnt/sdcard/Movies/BQMall_832x480_60_qp22.bin -t video/*
