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 :
