    Dixit Wikipedia, XMP signifie :
    Extensible Metadata Platform ou XMP est un format de métadonnées basé sur XML utilisé dans les applications PDF, de photographie et de graphisme. Il a été lancé par Adobe Systems en avril 2001 en étant intégré à la version 5.0 d’Adobe Acrobat.
    Étant basé sur XML, il gère un ensemble de tags dynamiques pour l’utilisation dans le cadre du Web sémantique.

  • FFmpeg does not convert .ts files to .mp4

    2 février 2021, par oo92

    I am trying to run this code to convert a .ts file in my Google Colab to a .mp4 file :

    


    import subprocess

infile = '/content/result/00000.ts'
outfile = '/content/result/video.mp4'

subprocess.run(['ffmpeg', '-i', infile, outfile])


    


    However, I don't see anything in /content/result/ except the .ts files. This is the output cell :

    


    CompletedProcess(args=['ffmpeg', '-i', '/content/result/00000.ts', '/content/result/video.mp4'], returncode=1)


    


  • Saving mp4 files into csv for training the data

    4 février 2021, par KSp

    I am very new to the computer vision field and I am trying to train my model and as a start of the work, I used a label encoder to label my videos for events I am using. Here I have two events which are accident and no accident.

    


    Folder Structure for the images :

    


    Colab_Notebooks
- accident(all the .jpg frames are here)
- nonaccident(all the .jpg frames are here)


    


    So my data.csv file looks like this and code given below.

    


    data.csv 
image_path,target
/content/drive/MyDrive/Colab_Notebooks/accident/accident_0000638.jpg,0.0
/content/drive/MyDrive/Colab_Notebooks/nonaccident/nonaccident_0002143.jpg,1.0
/content/drive/MyDrive/Colab_Notebooks/accident/accident_0000372.jpg,0.0
/content/drive/MyDrive/Colab_Notebooks/accident/accident_0000419.jpg,0.0
/content/drive/MyDrive/Colab_Notebooks/nonaccident/nonaccident_0001675.jpg,1.0
/content/drive/MyDrive/Colab_Notebooks/accident/accident_0000307.jpg,0.0
/content/drive/MyDrive/Colab_Notebooks/accident/accident_00001099.jpg,0.0
/content/drive/MyDrive/Colab_Notebooks/accident/accident_0000940.jpg,0.0
/content/drive/MyDrive/Colab_Notebooks/accident/accident_0000892.jpg,0.0
/content/drive/MyDrive/Colab_Notebooks/accident/accident_0000805.jpg,0.0
/content/drive/MyDrive/Colab_Notebooks/accident/accident_0000232.jpg,0.0
/content/drive/MyDrive/Colab_Notebooks/accident/accident_0000255.jpg,0.0
/content/drive/MyDrive/Colab_Notebooks/accident/accident_0000840.jpg,0.0
/content/drive/MyDrive/Colab_Notebooks/accident/accident_0000974.jpg,0.0


    


    The code i used for generating data.csv is as shown below :

    


    all_paths = os.listdir('/content/drive/MyDrive/Colab_Notebooks/')

folder_paths = [x for x in all_paths if os.path.isdir('/content/drive/MyDrive/Colab_Notebooks/' + x )]

print(f"Folder paths : {folder_paths}")
print (f"Number of folders: {len(folder_paths)}")
create_labels = ['accident','nonaccident']

data = pd.DataFrame()

image_formats = ['jpg']
labels = []
counter = 0
for i, folder_path in tqdm(enumerate(folder_paths), total = len(folder_paths)):
    if folder_path not in create_labels:
        continue
    image_paths = os.listdir('/content/drive/MyDrive/Colab_Notebooks/' + folder_path)
    label = folder_path

    for image_path in image_paths:
        if image_path.split('.')[-1] in image_formats:
            data.loc[counter,'image_path'] =  f"/content/drive/MyDrive/Colab_Notebooks/{folder_path}/{image_path}"
            labels.append(label)
            counter += 1
labels = np.array(labels)
# one-hot encode the labels
lb = LabelBinarizer()
labels = lb.fit_transform(labels)

#print(labels)

# save as CSV file
data.to_csv('/content/drive/MyDrive/Colab_Notebooks/data.csv', index=False)

# pickle the binarized labels
print('Saving the binarized labels as pickled file')
joblib.dump(lb, '/content/drive/MyDrive/Colab_Notebooks/lb.pkl')

print(data.head(5))


    


    I was able to do this fine because the dataset you see on top is frames which are jpg images. But I would like to do the same for videos.

    


    Colab_Notebooks
- accident(all the .mp4 clips are here)
- nonaccident(all the .mp4 clips are here)

Expected output:
/content/drive/MyDrive/Colab_Notebooks/accident/accident_0000638.mp4,0.0
/content/drive/MyDrive/Colab_Notebooks/nonaccident/nonaccident_0002143.mp4,1.0
/content/drive/MyDrive/Colab_Notebooks/accident/accident_0000372.mp4,0.0
/content/drive/MyDrive/Colab_Notebooks/accident/accident_0000419.mp4,0.0
/content/drive/MyDrive/Colab_Notebooks/nonaccident/nonaccident_0001675.mp4,1.0
/content/drive/MyDrive/Colab_Notebooks/accident/accident_0000307.mp4,0.0


    


    Could someone tell me how do I modify the code to read the video clips instead of images ?

    


  • Anomalie #4623 : Styles des fieldset dans l’espace privé

    19 avril 2021, par nicod _

    Pour info j’ai travaillé sur le regroupement des radios et checkbox dans des fieldsets :
    https://git.spip.net/spip-contrib-extensions/saisies/pulls/105

    Pour l’instant, ça ne fait que mettre un fieldset à la place du div comme contenur, et un legend à la place de label, ça génère donc un simple fieldset.editer :
