I am running into following error while passing arguments. Can anyone help me identify this problem? I'm passing instructions to my function in terminal like this:
python makeQuicktime.py -i /Volumes/P003A/TM_Cloud/Nagrania/Karta_04/XDROOT/Clip/D004C010_141026MM.MXF -f 25 -c prores
This is the main function - as you see I'v tried to pass argument --codec as string:
if __name__ == "__main__":
args = docopt(__doc__, version='makeQuicktime 0.0.1')
print args
cmd_args = ""
codec=str(args['--codec'])
makeQuicktime( args['--input'], fps=args['--fps'], codec=str(args['--codec']) )
os._exit(0)
The part of other function that this code is running (makeProRes, line 110 is the output variable):
subprocess.call([FFMPEG_PATH, 'i', input,
'-start_number', start_frame, '-r', fps,
'-c:v', 'prores',
'-profile:v', '2',
'-c:a', 'copy',
'-threads', cpus,
output
])
Error:

One of start_frame
, fps
, or cpus
is a number rather than a string. When you find out which, enclose it in str()
to convert it.
