Transcoding Mp4 video on Android with FFMPEG

Question

I've compiled FFMPEG binary from Bambuser project (refer question) and have pushed binary and .so files to application directory.

But when I try running FFMPEG with input file, it always complains file not found.

1|root@android:/data/data/com.bambuser.broadcaster # ls                        
cache           libavcodec.so   libavfilter.so  libswscale.so
ffmpeg          libavcore.so    libavformat.so  tutorial.mp4
lib             libavdevice.so  libavutil.so
1|root@android:/data/data/com.bambuser.broadcaster # ./ffmpeg -i tutorial.mp4 out.mp4

I've tried placing file in /sdcard and other locations, I always get same output

Hmm. I had made all files (including binary, so, video files) 777. It shouldn't matter isn't it? — Taranfx, May 14 '12 at 16:18
Try strace'ing it to see what it's really passing to open() or try instrumenting the code that prints that error and make sure it really means file not found, vs. being sloppy about applying that to other sorts of errors. — Chris Stratton, May 14 '12 at 16:48

i downloaded the code 'Archive for client versions 1.3.7 to 1.6.0.'. I found that in the build.sh file there's the line FLAGS="$FLAGS --disable-everything" that disable all the protocols for loading a file (file, http, etc.). commenting this line or enable the protocols that you need allow you to load correctly the file.
