Features

• Batch Processing: All posts are divided into groups based on the number of posts specified in the configuration GroupForProcessing (config/app.go). This allows for efficient batch processing of posts.
• Worker Distribution: The posts are distributed among workers, with the number of workers also specified in the configuration WorkerCount. This ensures that the workload is balanced and processed in parallel, improving the overall efficiency of the application.
• Video Concatenation: The application selects a main video file from the media directory and randomly selects an overlay video from the overlay directory using the SIGNS_VIDEO_PATH environment variable. The selected overlay video is concatenated to the end of the main video.
• Resolution Adjustment: The resolution of the videos is adjusted to 720x1280 pixels (vertical video) to ensure consistency.
• Output: The resulting concatenated video is saved in the media directory with the name processed.mp4.

All processed videos are saved in the database, and this data can be used for posting to other social networks.

Directory Structure

The directory structure for the Video Overlayer application should be as follows:

posts_dir/{post_id}/media

• posts_dir: The root directory containing all posts.
• {post_id}: A unique identifier for each post.
• media: A subdirectory within each post directory where the main video file (.mp4) is stored.

The application processes the videos as follows:

• It selects a main video file from the media directory.
• It randomly selects a video from the overlay directory uses SIGN_VIDEO_PATH env variable.
• The selected overlay video is concatenated to the end of the main video.
• The resolution of the videos is adjusted to 720x1280 pixels (vertical video) to ensure consistency.
