  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Returned non-zero exit status 1 / error code 1 : b''

    26 août 2015, par pufAmuf

    I’m trying to extract the video height via ffprobe into python, however I am having issues (with some videos).

    Here is my ffprobe command : ffprobe -v quiet -print_format compact=print_section=0:nokey=1:escape=csv -show_entries stream=height "some video here(bla)_25.mp4"

    It returns something like this

    720
    
(empty-line)
    
N/A

    Here is the code I used to extract the output for later processing :

    executecommand = 'ffprobe -v quiet -print_format compact=print_section=0:nokey=1:escape=csv -show_entries stream=height "' + CurrentVideoToBeProcessed + '"'
    

    
VideoHeight = subprocess.check_output(executecommand)

    This is the error that came about :

    subprocess.CalledProcessError : Command ’...’ returned non-zero exit
    status 1

    So when I modified the code to this :

    try:
    
    VideoHeight = subprocess.check_output(executecommand,shell=True,stderr=subprocess.STDOUT)
    
except subprocess.CalledProcessError as e:
    
    raise RuntimeError("command '{}' return with error (code {}): {}".format(e.cmd, e.returncode, e.output))

    This is the error I get :

    RuntimeError : command ’...’ return with error (code 1) : b’’

    I assumed at first the issue was with the file names, but certain videos work and certain don’t, irregardless of the file name.
    This is the output I get in python for videos that work :

    b’360\r\n\r\n’

    Any idea what’s going on ? Thanks !

    Edit
    It turns out the problem is in the file names after all. From what I gather so far at least, numbers in file-names seem to be causing the error.
    Edit2
    I re-ran the code after I closed several cmd instances and I am not getting the error anymore. I don’t know why. I am sure, however that if I were to convert hundreds of videos again I’ll get the error eventually as it has always happened eventually.
