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:

AV1 doesn't support interlaced frame.

Tried also the cmd as suggested from Fei Wang:

I wonder if AV1 generic doesn't support interlaced input video, then neither AV1 software encoders like av1_svt should be able to do it. Or may this mean interlaced output?

*i think* specification allow it, just current hw implementation via qsv does not exist (yet?).

You better ask some intel engineers about that.

But unhappily, the HDV --> av1_qsv transcoding I previous did on i17-12700/DG2 WS

.........................snip

By the way, neither this attempt claims about unsupported or wrong image structure format !?

may be it not even come to this line and abort earlier? (in compiled languages functions can be executed out of order they appear in file)

HDV --> av1_qsv transcoded as referenced above on the newer i17-12700/DG2

??

you mean why default ffmpeg does not trip over this line?

it silently ignores interlace and makes something flagged as interlaced but actually not?

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?

welll ..may be?

Also FHD --> av1_qsv with p010le works

If it works good enough for those goals may be you can just set cingg's format to progressive even if autodetect says interlaced, and try to render.

I'll try that also.

I can't notice differences at playback with VLC and FFplay (other than 16:9 vs 4:3 format as usual). And both visually with good qualities in my eyes.

Cingg Set Format Interlace Mode: Not interlaced
did the trick and both hdv and hd could be rendered
FFprobe reported it is pgogressiv, while native FFmpeg transcoding still say interlaced.
