Hello.
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
http://git.ffmpeg.org/gitweb/ffmpeg.git/blob/HEAD:/libavcodec/qsvenc.c#l852
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:
https://lists.cinelerra-gg.org/pipermail/cin/2024-November/009123.html 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 https://www.mail-archive.com/cin@lists.cinelerra-gg.org/msg08314.html
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?

You may add deinterlace filter before encoder after apply this patch: https://patchwork.ffmpeg.org/project/ffmpeg/list/?series=13372
