FFmpeg Map Metadata Not Working: A Guide for Tech Support

To convert videos using FFmpeg 7.1 and copy cover art from the MJPEG video stream, follow these steps:

1. First, ensure that you have FFmpeg installed on your system. If not, download it from the official FFmpeg website (https://www.ffmpeg.org/download.html) and install it.

2. Open your terminal or command prompt and navigate to the directory containing the video file you want to convert.

3. Run the following command to convert the main video stream and copy the cover art from the MJPEG video stream:

ffmpeg -i input.ext -c copy -map 0 -c:a copy -c:v mjpeg -metadata:s:v:0 cover_art=input.jpg output.ext

Replace input.ext with the name of your video file, and output.ext with the desired output file name. If your video file has a different format, replace ext with the appropriate extension (e.g., .mp4, .mkv, etc.).

4. In the command above, replace input.jpg with the name of the cover art file if it's different from the original video file. If you don't have a cover art file, you can remove it from the command.

5. Press Enter to execute the command, and FFmpeg will start converting the video while copying the cover art from the MJPEG video stream.

Summary:

• Install FFmpeg if not already installed.
• Navigate to the directory containing the video file.
• Run the FFmpeg command to convert the video and copy the cover art.
• Replace input.ext, output.ext, and input.jpg with your file names.
• Press Enter to execute the command and start the conversion.
