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.htmlAV1 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/[email protected]/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.

We can have a closer look at the av1_qsv output, possibly with loglevel verbose or debug on that WS, when I'm back again. I don't know what ffmpeg really does here, but as far it is accelerated (fps=561 for cfhd.mkv), viewable and playable, it will be good?
You may add deinterlace filter before encoder after apply this patch: https://patchwork.ffmpeg.org/project/ffmpeg/list/?series=13372 cmd: ffmpeg -hide_banner -qsv_device /dev/dri/renderD128 - hwaccel_output_format qsv -i input.mp4 -pix_fmt nv12 -vf vpp_qsv=deinterlace=advanced -c:v av1_qsv -f null - Thanks Fei_______________________________________________ ffmpeg-devel mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe"._______________________________________________ ffmpeg-devel mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
