Quality selection?

Conform https://flowplayer.org/docs/plugins.html#quality-selector I created the .m3u file and added the link to HLS video field.
We have 3 types of mp4 files combined to one m3u. Where I have to add this link to m3u to play with quality selection plugin?

The add the m3u URL to the “HLS Video” field in the advanced section and define the default and other video qualities in the “Configuration” tab.
