1. Enhance the Android multimedia framework providing additional Plugins for
user interaction
2. FFmpeg provides demuxers and av codecs;
-3. SDL provides basic library: thread, mutex, and timer, but all of sdl should
- be removed;
-4. NamExtractor is a extractor plugin, it would be loaded by Stagefright when
- Stagefright started.
-5. NamExtractor will load FFmpegExtractor, MplayerExtractor and VLCExtractor.
- but only FFmpegExtractor is implemented now.
-6. FFmpegExtractor is the reference to "ffmpeg/ffplay" to achieve.
-7. libstagefright_soft_ffmpegvdec plugin is video decoder
-8. libstagefright_soft_ffmpegadec plugin is audio decoder[TODO]
+3. FFmpegExtractor is a extractor plugin.
+4. libstagefright_soft_ffmpegvdec plugin is video decoder
+5. libstagefright_soft_ffmpegadec plugin is audio decoder

Why is named nam[NamExtractor]?
Requirements
================================================================================
-CyanogenMod 9.x (Ice Cream Sandwich)
-http://wiki.cyanogenmod.com/wiki/Galaxy_Nexus_(GSM):_Compile_CyanogenMod_(Linux)
+1. android_frameworks_native:
+https://github.com/omxcodec/android_frameworks_native.git
+branch: cm_maguro-10.1
-FFMPEG-0.11.1
-git://android.git.linaro.org/platform/external/ffmpeg.git
+2. android_frameworks_av:
+https://github.com/omxcodec/android_frameworks_av.git
+branch: cm_maguro-10.1
-SDL-1.3.0
-git@github.com:omxcodec/android_external_sdl.git
+3. android_external_ffmpeg

+branch: cm_maguro-10.1

- How to build
+How to build
================================================================================
1. Get the Source
- clone cm-9.1.0 source from CyanogenMod git:
- repo init -u git://github.com/CyanogenMod/android.git -b cm-9.1.0
- plz ref: http://wiki.cyanogenmod.com/wiki/Galaxy_Nexus_(GSM):_Compile_CyanogenMod_(Linux)
-
- clone my sources from the omxcodec{github} git!
in your "android/external" folder, run:
- stagefright-plugins:
+ stagefright-plugins(branch: master):
git clone git@github.com:omxcodec/stagefright-plugins.git stagefright-plugins
- ffmpeg:
- git clone git@github.com:omxcodec/android_external_ffmpeg.git ffmpeg -b linaro-0.11.1
- sdl:
- git clone git@github.com:omxcodec/android_external_sdl.git sdl
-
- in your "android/external" folder, run:
- cp stagefright-plugins/repo/local_manifest.xml ../.repo
- cd .. // go to android folder
- repo sync // sync "frameworks_base" code again!
-
- "repo sync" sync "frameworks_base" code again! of course, you can merge my
- android_external_ffmpeg code instread of "repo sync" frameworks_base. once you do,
- so you should pay attention to the "USES_NAM" flag, it is only in the
- "android/frameworks/base" directory
+ 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 android build system
- vi vendor/samsung/maguro/BoardConfigVendor.mk and add these lines to it
- USES_NAM := true
- ifdef USES_NAM
- COMMON_GLOBAL_CFLAGS += -DUSES_NAM
- endif
-
- ffmpeg:
- cd android/external/ffmpeg
- mm ffmpeg // NOT "mm", plz FIXME!
-
- cd android/external/sdl
- mm
-
- cd android/external/stagefright-plugins
- mm
+ 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
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 NamExtractor and FFmpegExtractor plugins:
+ 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 omxcode choose software decoder
+ 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/*
+
run it and enjoy!
