Ffmpeg-python: Passing flags to ffmpeg

Created on 2 Feb 2018 · 5Comments · Source: kkroening/ffmpeg-python

I would like to pass on the following flags to ffmpeg

.-nostdin 
 -loglevel error

Is it possible ?
The nostdin flag is required because ffmpeg swallows stdin. More info here.
The loglevel parameter would help a lot in reducing the verbosity of the ffmpeg output

For anybody that needs an example (like I did):

(
    ffmpeg
    .input(in_filename, ss=time)
    .output(out_filename, vframes=1)
    .global_args('-loglevel', 'error')
    .global_args('-y')
    .run()
)

I guess you just need do ffmpeg.intput('filename', nostdin=None)

@metaphox Dint know that one. Shouldn't that be likeffmpeg.input('filename', nostdin=true) ?
Also i guess passing -loglevel would be resolved when issue #30 is fixed

@kishaningithub That's correct

Done. See also #30.
