Description

Is there a way to get cover image of mp4 file? It doesnt show up in any of the metadata fields, like it does in jcodec library.

Contributor guide

Research direction
Investigate how FFmpeg extracts cover art from MP4 files (e.g., via attached pic streams) and whether javacv's FFmpegFrameGrabber can expose it. Consider adding a method to retrieve the cover image as a BufferedImage or Frame.
