Seeking doesn't work at all, with or without this tag.
The VOD stream reset its pts to zero for every few minutes.
But hls demuxer doen't handle #EXT-X-DISCONTINUITY at all.
HLSContext.seek_timestamp is absolute position for whole stream.
The seeking target may never reach, if it's greater than the reset
period (max pts),
I work around it in a hack way, to pretend to have continues pts.
I think my insane-frame-duration problem comes from the hack fix,
but not from code on master. so, AVFMT_TS_DISCONT tag may be
not necessary for master.
Anyhow, thanks a lot for your reply.

BTW: Is it necessary to store EXTINF duration as float, since some hls server
provide float duration?
