Creating farms of unique websites

Anomalie #4245 (Fermé) : Petit bug de sous_repertoire()
11 décembre 2018Découvert hier, un enchaînement tueur :
- <span class="CodeRay"><span class="local-variable">$demo</span> = sous_repertoire(_DIR_TMP, <span class="string"><span class="delimiter">'</span><span class="content">demo_</span><span class="delimiter">'</span></span>);
- <span class="comment">// $demo = 'tmp/demo_'</span>
- <span class="local-variable">$bug</span> = sous_repertoire(<span class="local-variable">$demo</span>, <span class="string"><span class="delimiter">'</span><span class="content">potiron</span><span class="delimiter">'</span></span>);
- </span>
Le système a rencontré une erreur lors de l’écriture du fichier tmp/demo/potiron/.plat.
En fait, lors de l’appel de
sous_repertoire($base, $subdir)
, la fonction vire les / et _ finaux de $base (mais pas le _ final éventuel de $subdir).
Il se retrouve ici à vouloir créer le répertoiretmp/demo/potiron
au lieu detmp/demo_/potiron
et n’y arrive pas, vu que le répertoire parent (demo) n’existe pas.Histoire¶
Après quelques fouilles archéologiques, il se trouve que le problème survient probablement avec r8196 qui refactore différemment le code de r6395 :
-6395 fil@rezo.n if (!preg_match(',[/_]$,', $base)) $base .= '/';
-8196 esj@rezo.n if (preg_match(',[/_]$,', $base)) $base = substr($base,0,-1);
-16035 fil@rezo.n $base = rtrim($base, '/_');
Le tout devait être, je suppose, pour prendre en compte les excentriques répertoires "plats" (dépendants maintenant de la présence de la constante _CREER_DIR_PLAT).
Corrections¶
Plusieurs corrections possibles :
- A) virer la constante _CREER_DIR_PLAT et ses actions, et le rtrim de ce souligné (on est en 2018…).
- B) simplement appliquer le rtrim du souligné si _CREER_DIR_PLAT est présent (ça corrige pas le bug que $subdir n’aurait alors pas ce rtrim non plus !)
- C) B + corriger le rtrim pour $subdir de la même manière.Je suis partisan de A) sur le trunk, et B) ou C) sur 3.2 et 3.1.
Des avis ?

FFmpeg fails to draw text
6 avril 2024, par Edoardo BalducciI've rarely used ffmpeg before, so, sorry If the question is too dumb.
I have a problem adding a text layer to a video frame using ffmpeg.


This is my current code :


import subprocess
from PyQt5.QtGui import QPixmap, QImage
from PyQt5.QtWidgets import QLabel

class VideoThumbnailLabel(QLabel):
 def __init__(self, file_path, *args, **kwargs):
 super().__init__(*args, **kwargs)
 self.video = video
 video_duration = self.get_video_duration(file_path)
 thumbnail_path = self.get_thumbnail(file_path, video_duration)
 if thumbnail_path:
 self.setPixmap(QPixmap(thumbnail_path).scaled(160, 90, Qt.KeepAspectRatio))
 self.setToolTip(f"{video.title}\n{video.description}")

 def get_video_duration(self, video_path):
 """Returns the duration of the video in seconds."""
 command = [
 'ffprobe', '-v', 'error', '-show_entries',
 'format=duration', '-of',
 'default=noprint_wrappers=1:nokey=1', video_path
 ]
 try:
 result = subprocess.run(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE, text=True)
 if result.returncode != 0:
 print(f"ffprobe error: {result.stderr}")
 return 0
 duration = float(result.stdout)
 return int(duration) # Returning duration as an integer for simplicity
 except Exception as e:
 print(f"Error getting video duration: {e}")
 return 0

 def get_thumbnail(self, video_path, duration):
 """Generates a thumbnail with the video duration overlaid."""
 output_path = "thumbnail.jpg" # Temporary thumbnail file
 duration_str = f"{duration // 3600:02d}:{(duration % 3600) // 60:02d}:{duration % 60:02d}"
 command = [
 'ffmpeg', '-i', video_path,
 '-ss', '00:00:01', # Time to take the screenshot
 '-frames:v', '1', # Number of frames to capture
 '-vf', f"drawtext=text='Duration: {duration_str}':x=10:y=10:fontsize=24:fontcolor=white",
 '-q:v', '2', # Output quality
 '-y', # Overwrite output files without asking
 output_path
 ]
 try:
 result = subprocess.run(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
 if result.returncode != 0:
 print(f"ffmpeg error: {result.stderr}")
 return None
 return output_path
 except Exception as e:
 print(f"Error generating thumbnail with duration: {e}")
 return None



and it is used like this :


for i, video in enumerate(self.videos):
 video_widget = VideoThumbnailLabel(video.file)
 video_widget.mousePressEvent = lambda event, v=video: self.onThumbnailClick(
 v
 )
 self.layout.addWidget(video_widget, i // 3, i % 3)



I'm facing a problem where I am not able to get the thumbnail if I try to add the duration (I've tested it without the draw filter and worked fine)


I get this error (from the
result.returncode
) that I'm not able to comprehend :
