  • Mise à disposition des fichiers

    14 avril 2011, par

    Par défaut, lors de son initialisation, MediaSPIP ne permet pas aux visiteurs de télécharger les fichiers qu’ils soient originaux ou le résultat de leur transformation ou encodage. Il permet uniquement de les visualiser.
    Cependant, il est possible et facile d’autoriser les visiteurs à avoir accès à ces documents et ce sous différentes formes.
    Tout cela se passe dans la page de configuration du squelette. Il vous faut aller dans l’espace d’administration du canal, et choisir dans la navigation (...)

  • Subprocess doesn't return expected result

    8 avril 2023, par Gren Man

    Subprocess doesn't return expected result

    


    I have been trying getting info from video files using ffprobe

    


    But I stumbled upon unexpected results, here are some test I've done

    


    First test

    


    # ffprobe -v error -select_streams v:0 -show_entries stream=height,width -of csv=s=x:p=0 
proc = subprocess.Popen(['ffprobe', '-v', 'error', '-select_streams', 'v:0', '-show_entries', 
       'stream=height,width', '-of', 'csv=s=x:p=0 ', video_path],
       stdout=subprocess.PIPE, stdin=subprocess.PIPE)

# proc.stdout.read() Returns  b'widthXheightt\r\n'
v_resolution = proc.stdout.read().decode('utf-8').replace('\r', '').replace('\n', '')
# Result 'widthXheight'


    


    First test was successful.

    


    Second test

    


    # ffprobe -v error -select_streams v:0 -show_entries stream=display_aspect_ratio -of default=noprint_wrappers=1:nokey=1
proc = subprocess.Popen(['ffprobe', '-v', 'error', '-select_streams', 'v:0', '-show_entries',
       'stream=display_aspect_ratio','-of default=noprint_wrappers=1:nokey=1', video_path],
       stdout=subprocess.PIPE, stdin=subprocess.PIPE)

# proc.stdout.read() Returns b''
a_r = proc.stdout.read().decode('utf-8').replace('\r', '').replace('\n', '')
# Result ''


    


    Hmm, this doesn't sounds right I thought result should be e.g. 16:9

    


    I tried putting code to CMD which returned aforementioned result

    


    Third test

    


    # ffprobe -v error -select_streams v -of default=noprint_wrappers=1:nokey=1 -show_entries stream=r_frame_rate
proc = subprocess.Popen(['ffprobe', '-v', 'error', '-select_streams', 'v', '-of',
       'default=noprint_wrappers=1:nokey=1','-show_entries', 'stream=r_frame_rate',
       video_path], stdout=subprocess.PIPE, stdin=subprocess.PIPE)

# proc.stdout.read() Returns b'30/1'
fps = proc.stdout.read().decode('utf-8').replace('\r', '').replace('\n', '') + ' fps'
# Result 30/1 fps


    


    Just as expected this returned subarashi result

    


    But what happened in a second test ? Can somebody explain it to me ? I used stderr which returned :

    


    Failed to set value 'foo.mp4' for option 'of default=noprint_wrappers=1:nokey=1': Option not found


    


    Result of python code

    


    Result

    


  • Cannot find installation of real FFmpeg (which comes with ffprobe)

    29 mars 2023, par Asm Goni

    I was trying to fit a generator into a model and I got this error : 
AssertionError: Cannot find installation of real FFmpeg (which comes with ffprobe).

    



    I have looked over many of the solutions on GitHub and other questions on Stack Overflow but none of them worked for me.

    



    Here is one of the commands I ran :

    



    sudo add-apt-repository ppa:mc3man/trusty-media  
sudo apt-get update  
sudo apt-get install ffmpeg  
sudo apt-get install frei0r-plugins  


    



    pip list also indicates the presence of ffmpeg-1.4

    



    In addition, I tried force reinstalling and updating ffmpeg just in case any dependencies were not installed properly.

    



    I also set the skvideo's path for ffmpeg manually :

    



    skvideo.setFFmpegPath('/usr/local/lib/python3.6/dist-packages/ffmpeg/')


    



    This returns : /usr/local/lib/python3.6/dist-packages/skvideo/__init__.py:306: UserWarning: ffmpeg/ffprobe not found in path: /usr/local/lib/python3.6/dist-packages/ffmpeg/
  warnings.warn("ffmpeg/ffprobe not found in path: " + str(path), UserWarning)

    



    By the way, when I try installing, it also returns this error, I don't know what to do about this :

    



    Get:127 http://archive.ubuntu.com/ubuntu bionic/main amd64 vdpau-driver-all amd64 1.1.1-3ubuntu1 [4,674 B]
Fetched 60.4 MB in 7s (8,769 kB/s)
E: Failed to fetch http://security.ubuntu.com/ubuntu/pool/main/w/wavpack/libwavpack1_5.1.0-2ubuntu1.1_amd64.deb  404  Not Found [IP: 91.189.88.149 80]
E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?


    



    I ran apt-get update --fix-missing and that didn't make anything better.

    



    Is there a solution to this ?

    


  • Revision a8e674de4f : set_maps : Flush encoder. According to the current API spec we need to call vpx_

    16 août 2014, par Dmitry Kovalev

    Changed Paths :
     Modify /examples/set_maps.c



    set_maps : Flush encoder.

    According to the current API spec we need to call vpx_codec_encode() until
    vpx_codec_get_cx_data() returns NULL.
