I need to decode h264 file to YUV on Android 2.3+. As I understand I need to communicate with Stagefright, as it`s the only way now, after closing access with OpenMAX IL implementations. I have used FFmpeg 0.10 (and tried 0.9/0.9.1..) for this issue, compiled it with NDK7 (and also tried NDK6b with the same result):

So, entering next command give me error with 480p: ffmpeg -i /sdcard/Video/480p.mp4
Stopped (signal) ffmpeg -i /sdcard/Video/480p.mp4

Android-developers, does anybody know what this error means and how to deal with it? I tried to make DSP window bigger, but with no luck. Commands like "stagefright /sdcard/Video/480p.mp4" works fine.
P.S. Additionally I found that on some bigger files (720p) Android answers next:
[libstagefright_h264 @ 0xd479b0] Decode failed: 80000000
