the scale filter is kind of broken on master atm: [swscaler @ 0x7fdbd0003d80] Unsupported input (Operation not supported): fmt:yuv420p csp:bt709 prim:reserved trc:bt709 -> fmt:yuv420p csp:bt709 prim:reserved trc:bt709
<llyyr>
I'll bisect what broke it
<llyyr>
it was >avfilter/vf_scale: switch to new swscale API
<llyyr>
not very helpful
<llyyr>
haasn: ^
<Traneptora>
llyyr: can you provide a sample to reproduce?
<llyyr>
I can't share these files but I'll see if just 1 frame is enough to reproduce, give me a bit
<llyyr>
Traneptora: https://0x0.st/8Hr_.mp4 this should be enough: ffmpeg -i 8Hr_.mp4 -vf "scale=1920:1080" test.mp4
<llyyr>
works on 7.1, not on master
<Traneptora>
llyyr: I just reproduced it with: ffmpeg -color_trc bt709 -colorspace bt709 -color_primaries 3 -f lavfi -i testsrc2,format=yuv420p -vf scale=1920x1080 -frames 1 -f null -
<Traneptora>
problem appears to be the color_primaries=3
<llyyr>
I guess it doesn't like unknown primaries?
<llyyr>
assuming that's what reserved means
<llyyr>
yep it fails: return prim > AVCOL_PRI_RESERVED0 && prim < AVCOL_PRI_NB && prim != AVCOL_PRI_RESERVED;
<jamrial>
reserved is not "unknown", it's a value that should not be used
<jamrial>
why does your sample use it in the first place

<llyyr>
well all the samples that fail come from the same source, so probably a broken encoder
<Traneptora>
jamrial: llyyr: yea, but it shouldn't fail if there's no csp conversion to be done

22:15:48 <steven-netint> kierank: > "instead of 350MB of binary blobs" Is this a requirement for MA35D? I haven't got the chance to use one yet
<kierank>
Yes
