[FFmpeg-user] struggling for using stagefright of ffmpeg on Android

[hsu tom]

Dear Carl

This log.txt is produced from android ndk-bulid.

Thanks a lot.

By the way , this is my way about buildind files ".a" from ffmpeg

1. fix ffmpeg/configure  --

ori : enabled libstagefright_h264  && require_cpp libstagefright_h264
"binder/ProcessState.h media/stagefright/MetaData.h

fixed : enabled libstagefright  && require_cpp libstagefright_h264
"binder/ProcessState.h media/stagefright/MetaData.h

This is in order to avoid the error

ERROR: libstagefright_h264 not found

2. use ffmpeg/tools/bulid_stagefright

creat 5 file

libavcodec.a, libavformat.a, libavutil.a, libpostproc.a, libswscale.a

3. use

use android.mk and command "ndk-bulid" to bulid .so file

4. error occured

Sincerely,

Tom Hsu
