Subject: [PATCH] Fix chapter detection in video probing

Added -show_chapters flag to ffprobe command to retrieve chapter
information. Parse chapters from JSON output and set HasChapters
field when chapters are present.

Files with chapters will now correctly show 'Chapters: Yes' in
the file information display.
