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.
+3. NamExtractor is a extractor plugin, it would be loaded by Stagefright when

+4. libstagefright_soft_ffmpegvdec plugin is video decoder
+5. libstagefright_soft_ffmpegadec plugin is audio decoder

1. Get the Source
stagefright-plugins:
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
+ git clone git@github.com:omxcodec/android_external_ffmpeg.git ffmpeg -b omxcodec-1.0
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!
- // of course, you can merge my android_external_ffmpeg code instread of
