4. libstagefright_soft_ffmpegvdec plugin is video decoder
5. libstagefright_soft_ffmpegadec plugin is audio decoder
================================================================================
Why is named nam[NamExtractor]?
================================================================================
Namtso, or Lake Nam, is one of the three holy lakes in Tibet Autonomous Region
and should not be missed by any traveler to Tibet. In Tibetan, Namtso means
"Heavenly Lake." It is famous for its high altitude and imposing scenery.
I used to travel there in 2011 Sep.
================================================================================
Requirements
================================================================================
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
[email protected]: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 [email protected]:omxcodec/stagefright-plugins.git stagefright-plugins
ffmpeg(branch: cm_maguro-10.1):
git clone [email protected]: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/*
run it and enjoy!
