Creating HLS variants with FFMPEG

[madkap]

I am starting with a high res video file and I would like to create 3 variants, low quality, mid quality, and high quality for mobile streaming. I want these mid/low/high variants to be segmented into ts pieces that one singular m3u8 file will be pointing that. Is there a way to do this in one line in ffmpeg?

I have successfully generated an m3u8 file and ts segments with ffmpeg, do I need to do this 3x and set specs for low/mid/high? If so, how do I get the singular m3u8 file to point to all variants as opposed to one for each variant?


This is the command I used to generate the m3u8 file along with the ts segments.
ffmpeg -i C:\Users\george\Desktop\video\hos.mp4 -strict -2 -acodec aac -vcodec libx264 -crf 25 C:\Users\user\Desktop\video\hos_Phone.m3u8

Well, better approach (optimal from data efficiency) will be to use SVC...
