Recently I teached cinelerra-gg to use qsv encoders in ffmpeg
(libavcodec)
and some test were working but some not.
We nailed it down to top-field first material, like HDV files. bff
files
like consumer version of DV and progressive worked fine.
I looked at source and ... I thought condition at
<a class="moz-txt-link-freetext" href="http://git.ffmpeg.org/gitweb/ffmpeg.git/blob/HEAD:/libavcodec/qsvenc.c#l852">http://git.ffmpeg.org/gitweb/ffmpeg.git/blob/HEAD:/libavcodec/qsvenc.c#l852</a>
must contain case for bff, but I tried this and it was reportedly not
helping?
We currently set flags = ildct+ilme on interlaced streams, I hope to
avoid
special-casing qsv encoders, but may be we have no other choice?
I asked user (Terje) to add +ildct flag to his normal system ffmpeg
line
and it started to fail too:

AV1 doesn't support interlaced frame.
We can dual check to transcode hdv to av1_qsv again, as I did with ffmpeg in this post

My issue now currently on Kaby Lake is that I have no hdv.m2t file stored and could not find a download link with example hdv. Suggestion?
