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.
