    The inportant row is USB Video Device : I/O error
    
I've tried also to add shell=True to the Popen but with the same result.

    


    Doing some tests I found that using pycharm debug mode or simply lunching the same code inside "Pycharm Python Console" no more I/O error and all seems to work. I think something changes in the environment created for the subrocess but I wasn't able to understand what PyCharm is doing under the hood.

    


    Here the output inside PyCharm Python Console

    In short the errors are :

    


    [NULL @ 00000000006645c0] Unable to find a suitable output format for 'rtmp://a.rtmp.youtube.com:1935/live2/the-stream-key
'
rtmp://a.rtmp.youtube.com:1935/live2/the-stream-key: Invalid argument
[dshow @ 0000000000607400] real-time buffer [screen-capture-recorder] [video input] too full or near too full (545% of size: 3041280


    


    I have tried with and without the :1935 port number, with ffmpeg_x64.exe but no difference. Is the stream key the invalid argument or something else ?
