ABS HLS with GStreamer

[Samyak]

Makes sense. So currently I'm trying to have all the playlists in a
separate pipeline since that prevents me from writing a lot of duplicate
code. Is there any drawback to having each resolution on a separate
pipeline instead of using tee and doing everything in just one pipeline?

Thanks!
