FFmpeg deletes segments based on its own transcoding progress,
but we need to delete segments based on client download progress.
Since disk and GPU speeds vary, using hlsenc's built-in deletion
will result in premature deletion of some segments. As a consequence,
the server has to constantly respin new ffmpeg instances, resulting
in choppy video playback.
