How to add a new video format to an existing encoded video

[MohamedAbdel-wahed]

I have a video that's encoded in two formats (Low format , high format)

I want to add a new format (medium format)

But when i added the new format It deleted the old m3u8 file and added a new one that's reading the new format

My question is How to add the medium format without overwriting the old formats 😪
