running command line programs in background using python os or subprocess module

I am trying to run a command using os or subproccess module in python. the command prompt window briefly flickers before terminating. Is there a way of eliminating that popping up of command prompt window..?

For example:

os.system("ffmpeg -i output.wav output.flac")

Is there a way I can run this in the background so that user may not notice this..?

I am running windows 7 with python 2.7.

def asyncRun(command): os.system(command)

t = Thread(target=asyncRun, args=('ping 127.0.0.1 -s 271',)) t.start()

works on windows 10 + EMET + 2.7

The easiest thing would be to try to take advantage of the subproccess modules partial support for the STARTUPINFO structure. Something like this:

info = subprocess.STARTUP_INFO()
info.dwFlags = subprocess.STARTF_USESTDHANDLES | subprocess.STARTF_USESHOWWINDOW
info.wShowWindow = subprocess.SW_HIDE

process = subprocess.Popen("ffmpeg -i output.wav output.flac", startupinfo=info)
process.wait()

of coarse ... you even tagged it with the module you would use ...

subproccess.Popen("ffmpeg -i output.wav output.flac".split(),shell=True).communicate()

should do it ...
