Многообразный поля схвати неудар в лунку to ffmpeg not found

гm using Ubuntu 14.04 and have compiled ffmpeg 2.8.4 from source with these options:

./configure --enable-gpl --enable-libass --enable-libfaac --enable-libfdk-aac --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-librtmp --enable-libtheora --enable-libvorbis --enable-libvpx --enable-x11grab --enable-libx264 --enable-nonfree --enable-version3 --enable-shared

I have в set of поля number consecutively from 0. n and have tried to использовал the "%03d" туз part of my неудар в лунку like so:

ffmpeg -y -pix_fmt yuv420p -s qvga -start_number 0 -i picture%03d.yuv -f mp4 -vcodec libx264 -s qvga -an -threads 0 output.mp4

With and without the start_number it fails to find the поля and yields this ошибка message on the конечный:
