The HLS specification states the following about EXT-X-TARGETDURATION
4.3.3.1. EXT-X-TARGETDURATION
The EXT-X-TARGETDURATION tag specifies the maximum Media Segment
duration. The EXTINF duration of each Media Segment in the Playlist
file, when rounded to the nearest integer, MUST be less than or equal
to the target duration; longer segments can trigger playback stalls
or other errors. It applies to the entire Playlist file. Its format
is:
#EXT-X-TARGETDURATION:<s>
where s is a decimal-integer indicating the target duration in
seconds. The EXT-X-TARGETDURATION tag is REQUIRED.
Currently the dashenc rounds the duration to the next integer,
rather than rounding the duration to the nearest integer.
