Hi, i ran this code in python and show me the output at real time from shell:
os.system('ffmpeg -i VIDEO.mp4 -n -f avi -r 24.00 -vcodec mpeg4 -vtag XVID -filter:v scale=w=480:h=360 -aspect 4:3 -b:v 520k -acodec libmp3lame -ar 44100 -b:a 128k -ac 2 VIDEO_OUTPUT.avi')
how do that in rust ?
You are looking for the
std::process::Command struct. By default it will forward
stderr to the parent's
stderr (i.e. yout terminal) while the program is running.
Check out the API docs for some examples:
Something big to point out is that the
Command struct doesn't let you pass a single command string that will be run by the shell. Instead, it tells the OS to start a program directly, so if you want to run a shell command you'll need to do that yourself (e.g.
Command::new("sh").arg("-c").arg("ffmpeg -i VIDEO.mp4 ...")).
