I'm trying to use FFmpeg to package three MPEGTS streams that are the same
source at different resolutions, bitrates and overall quality profile into
an ABR HLS feed.
I can make it work using an ffmpeg process per MPEGTS input / HLS output
and then manually creating a playlist but I'm trying to figure out if
there's an elegant way to do it with a single process or if there are other
advantages in doing so.
