 sense to not generate all the HLS segments by default for my use case (not
 a live stream, but a fixed-size video with different resolutions served
 through HLS to allow the in-browser player to auto-select the appropriate
 one for the client's bandwidth).

 no problem, you can use hls_list_size to set it :)
 Does this mean, we will always lose the first segment during live
 streaming? If yes, then this still sounds like a bug.
