• How to save variables at start of script for use later if script needs to be re-run due to errors or bad user input

  28 novembre 2023, par slyfox1186

  I have a script that uses GitHub's API to get the latest version number of the repositories that I am trying to download and then compile.

  


  Due to the fact that without using a specialized token from GitHub you are only allowed 50 API calls a day vs the 5000 a day with the API user token.

  


  I want to be able to parse all of the repositories and grab the version numbers that my script will then import into the code up front so in case someone who accidentally cancels the build in the middle of it (for who knows what reasons) wont have to eat up their 50 day API call allowance.

  


  Essentially, store each repo's version number, if the user then needs to rerun the script and version numbers that have been saved so far will be skipped (thus eliminating an API call) and any numbers that are still needing to be sourced will be called and then stored for used in the script.

  


  I am kinda of lost for a method on how to go about this.

  


  Maybe some sort of external file can be generated ?

  


  So what my script does is it builds FFmpeg from source code and all of the external libraries that you can link to it are also built from their latest source code.

  


  The code calls the function git_ver_fn and passes arguments to it which are parsed inside the function and directed to another functions git_1_fn or git_2_fn which passed those parsed arguments that have been passed on to the CURL command which changes the URL based on the arguments passed. It uses the jq command to capture the GitHub version number and download link for the tar.gz file.

  


  It is the version number I am and trying to figure out the best way to store in case the script fails and has to be rerun, which will eat up all of the 50 APT limit that GitHub imposes without a token. I can't post my token in the script because GitHub deactivates it and thus the users will be SOL if they need to run the script more than once.

• How to Convert 16:9 Video to 9:16 Ratio While Ensuring Speaker Presence in Frame ?

  28 avril 2024, par shreesha

  I am tried so many time to figure out the problem in detecting the face and also it's not so smooth enough to like other tools out there.

  


  So basically I am using python and Yolo in this project but I want the person who is talking and who the ROI (region of interest) is.

  


  Here is the code :

  


  from ultralytics import YOLO
from ultralytics.engine.results import Results
from moviepy.editor import VideoFileClip, concatenate_videoclips
from moviepy.video.fx.crop import crop

# Load the YOLOv8 model
model = YOLO("yolov8n.pt")

# Load the input video
clip = VideoFileClip("short_test.mp4")

tacked_clips = []

for frame_no, frame in enumerate(clip.iter_frames()):
    # Process the frame
    results: list[Results] = model(frame)

    # Get the bounding box of the main object
    if results[0].boxes:
        objects = results[0].boxes
        main_obj = max(
            objects, key=lambda x: x.conf
        )  # Assuming the first detected object is the main one

        x1, y1, x2, y2 = [int(val) for val in main_obj.xyxy[0].tolist()]

        # Calculate the crop region based on the object's position and the target aspect ratio
        w, h = clip.size
        new_w = int(h * 9 / 16)
        new_h = h

        x_center = x2 - x1
        y_center = y2 - y1

        # Adjust x_center and y_center if they would cause the crop region to exceed the bounds
        if x_center + (new_w / 2) > w:
            x_center -= x_center + (new_w / 2) - w
        elif x_center - (new_w / 2) < 0:
            x_center += abs(x_center - (new_w / 2))

        if y_center + (new_h / 2) > h:
            y_center -= y_center + (new_h / 2) - h
        elif y_center - (new_h / 2) < 0:
            y_center += abs(y_center - (new_h / 2))

        # Create a subclip for the current frame
        start_time = frame_no / clip.fps
        end_time = (frame_no + 1) / clip.fps
        subclip = clip.subclip(start_time, end_time)

        # Apply cropping using MoviePy
        cropped_clip = crop(
            subclip, x_center=x_center, y_center=y_center, width=new_w, height=new_h
        )

        tacked_clips.append(cropped_clip)

reframed_clip = concatenate_videoclips(tacked_clips, method="compose")
reframed_clip.write_videofile("output_video.mp4")


  


  So basically I want to fix the face detection with ROI detection where it can detect the face and make that face and the body on to the frame and making sure that the speaker who is speaking is brought to the frame
