@yuling Thanks for adding this to the forum! I would also love to see this functionality in Obsidian.
I like to have my video resources embedded, only once, at the top of my notes file for that video. (I use iframes for this, currently.) I would love it if I could write notes below the video area with timestamps, without creating more embedded links. Clicking a timestamp “link” should just fast-forward / rewind the main video player to that part of the video.
At least that’s how I would envision it, which I think is what you’re already suggesting. Consider this comment another vote for this plugin to get made!!
