video buffers when on loop and when seeking

[sanin564]

The Bug

we are using hls video format for playing videos, and videos are buffering when :

• seeking to a specific position.
• in case of looping is on, and when video completed and then starts to play from beginning.

Expected behavior

When on loop, the video should play seemlessly without buffering.

        fvp.registerWith(options: {
          'player': {
            'demux.buffer.ranges': '8',
          }
        });

thank you for the response. i've tried the solution you shared. it has reduces the buffering when on loop(can't say no buffering at all), but when seeking, its still buffering, also, also when video ended and starts playing from first, its giving a glitched effect, i've attached a video as well.
