Comment (by malakudi):

 With my little understanding of the ffmpeg code, I think that mpegts
 encoder does not suffer from the issue of nvenc interlaced encoding
 because it uses the flags from payload and not packet
 (ts_st->payload_flags).
 I couldn't understand why matroska encoder also doesn't suffer from the
 issue.

 I will try to modify hls encoder (hlsenc.c) to also use the flags from
 payload.
