Question

I am trying to batch convert few files in a folder using ffmpeg2theora.

for filename in $(pwd)/*
    do
    ffmpeg2theora -v 6 -a 5 $filename && mv $filename finished/
    done;

But now the code waits for one video to finish before converting another one. How do i convert all videos at the same time in the background ? Its giving me verbose output also which i dont want.

Answer 1

Add a single ampersand to the end of the command to start it in the background. To redirect output into nirvana, you can use > /dev/null

ffmpeg2theora -v 6 -a 5 $filename > /dev/null 2>&1  && mv $filename finished/ > /dev/null 2>&1 &
