Always get suspended when run youtube-dl in background

[cxbig]

I found that I have no way to run youtube-dl in background.
I tried all possible options to make it running in silence. But I still get 'suspended' job:

% stty -tostop && youtube-dl -q -i --no-warnings -o '%(id)s.%(ext)s'  $video_url >/dev/null 2>&1 &
[1] 53435
%
[1]  + 53435 suspended (tty output)  youtube-dl -q -i --no-warnings -o '%(id)s.%(ext)s'  > /dev/null 2>&1

Local env

[debug] youtube-dl version 2016.08.10
[debug] Python version 2.7.12 - Darwin-15.6.0-x86_64-i386-64bit

How are you launching youtube-dl? From a shell or inside a shell script?

A workaround:

• Create ~/ffmpeg_wrapper.sh with the following contents:

#!/bin/bash
ffmpeg -d $*

• chmod +x ~/ffmpeg_wrapper.sh
• youtube-dl -o '%(id)s.%(ext)s' --ffmpeg-location ~/ffmpeg_wrapper.sh $video_url

See https://github.com/FFmpeg/FFmpeg/blob/ae1dd0c/ffmpeg.c#L384 for what's broken and why -d works.

UPDATE: Fix commands in the workaround.

@jdunn0 I tried both command line and script. Same behavior.

Oops, there's something wrong in my previous post. I've updated it. Could you try again?

@yan12125 Thanks, your solution is working well.

[yan12125]

Thanks for your feedback. I'll check whether including -d in youtube-dl is OK or not.

Thanks to @johnhawkinson (#10996), this will be fixed in the next version.
