Why do videos have to buffer when you rewind on media players(eg YouTube)

312 viewsOtherTechnology

If I watch to 1:20 in then click back to 1:00 the video will load, but if I’ve already watched that part wouldn’t it be “stored” on my side of the browser?

videos are cached into ram. Ram is small, videos are big and people are already complaining about browser ram usage.

So when you are done watching a cached part of video, the browser chucks it and uses the space to cache the next section of video.

Seeking backwards is generally not expected, so it generally doesnt cause a problem, therefore it is considered fine
