Hi, Raja.
To create an HLS playlist from an MP4 video without re-encoding, you can use FFmpeg.
However, changing the format to HLS usually involves some form of re-encoding.
But, if you want to avoid altering the video's quality and characteristics, you can copy the existing codecs.
But this is little complex work and need some efforts.
I am interested in this work, but I need at least 400usd for this work.
Thank you.
Irfan.
