Parser.add_argument('-i', '-input', help='File Name', required=True) Parser = argparse.ArgumentParser(description='View ffprobe output') Return FFProbeResult(return_code=result.returncode,Įxample usage, echoing the resulting json string: if _name_ = '_main_': Result = n(command_array, stdout=subprocess.PIPE, stderr=subprocess.PIPE, universal_newlines=True) The json output from ffprobe is simple enough to parse in python having to install a third-party library. Unsupported codec with id 114 for input stream 0 P = subprocess.Popen(cmnd, stdout=subprocess.PIPE, stderr=subprocess.PIPE)Īnd I see the correct output: =output=įfprobe version 0.7.3-4:0.7.3-0ubuntu0.11.10.1, Copyright (c) 2007-2011 the Libav developersĬonfiguration: -extra-version='4:0.7.3-0ubuntu0.11.10.1' -arch=amd64 -prefix=/usr -enable-vdpau -enable-bzlib -enable-libgsm -enable-libschroedinger -enable-libspeex -enable-libtheora -enable-libvorbis -enable-pthreads -enable-zlib -enable-libvpx -enable-runtime-cpudetect -enable-vaapi -enable-gpl -enable-postproc -enable-swscale -enable-x11grab -enable-libdc1394 -enable-shared -disable-static So after these changes here is a sample script: #!/usr/bin/pythonĬmnd = you need to pass -loglevel and option of loglevel quiet as separate arguments i.e.

My ffprobe (ffprobe 0.7.3-4:0.7.3-0ubuntu0.11.10.1) doesn't seems to accept -i flag, input file is just passed as last argument.

Other than that it seems to be working, are you not seeing output after fixing #1 ?Įdit: Looks like you are having problem with ffprobe commandline, so I installed it and changes you require are:

shell=True is usually not needed and is unnecessary burden.

args list to Popen has last argument as -i filename which is a syntax error use '-i '+filename instead.
