Transcoding Mp4 video on Android with FFMPEG

0

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

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

• Did you try specifying full path names? - mark4o
• yes. Both relative, absolute. - Taranfx

• Hmm. I had made all files (including binary, so, video files) 777. It shouldn't matter isn't it? - Taranfx
• 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
