Generate Posters

A powerful feature of this library is the ability to generate posters for your video files automatically. This ensures that users do not encounter any blinking or white screens between videos, as the poster is pre-generated from the first frame of each video.

If you'd like to generate posters, you can use a separate repository called generate_poster, which provides a simple Bash script to automatically extract the first frame from each video and save it as a poster image.

Steps to Generate Posters:

1. Clone the generate_poster Repository

   First, clone the generate_poster repository:

   git clone https://github.com/fix2015/generate_poster.git
   

2. Navigate to the Project Folder

   After cloning, navigate to the generate_poster project folder:

   cd generate_poster
   

3. Run the Script to Generate Posters

   The repository contains a Bash script (generate_poster.sh) that will automatically extract the first frame from each .mp4 video in the directory and save it as a .jpg image. Run the script with:

   bash generate_poster.sh
   

The generate_poster.sh Script:

Here is the content of the generate_poster.sh script, which you can use to generate posters for your video files:

#!/bin/bash

# Find all .mp4 files in the current folder and extract the first frame as posters
for video in *.mp4; do
    # Check if the file exists (in case there are no .mp4 files)
    if [[ -f "$video" ]]; then
        echo "Processing $video..."
        # Extract the first frame
        ffmpeg -i "$video" -vf "select=eq(n\,0)" -vsync vfr -q:v 2 "${video%.mp4}_poster.jpg"
        echo "First frame extracted for $video."
    else
        echo "No .mp4 files found in the current folder."
    fi
done

How it Works:

• The script uses ffmpeg to extract the first frame of each .mp4 video.
• The first frame is saved as a .jpg image in the same folder as the video, with the _poster suffix added to the filename.
• This process allows you to generate high-quality posters to be used in your interactive video player.

Example:

If you have the following video files in your directory: video1.mp4 video2.mp4 video3.mp4

After running the script, you will have the following poster images generated:

These posters can then be used in your video player configuration to enhance the user experience by preventing flickering or a white screen between video transitions.
