Hey folks,
I'm trying to reencode a 10 Bit HEVC to 10 Bit AV1 while keeping the HDR
metadata intact.
Sadly, I don't see any HDR metadata with VLC at the reencoded AV1 clip.
The only thing I see are very cold looking colors, have a look at my
encode command:
/usr/bin/ffmpeg -i "/tmp/VODProcessing/Test (2022) - [2160p UHD].m4v"
-map 0:0 -c:v libsvtav1 -b:v 7864320 -maxrate:v 8257536 -bufsize
31457280 -vf zscale=width=3840:height=2160 -svtav1-params
"input-depth=10:fast-decode=1:color-primaries=9:transfer-characteristics=16:matrix-coefficients=9:mastering-display=G(0.265,0.69)B(0.15,0.06)R(0.68,0.32)WP(0.3127,0.329)L(4000.0,0.005):content-light=368,226:enable-hdr=1"
-pix_fmt yuv420p10le -color_trc smpte2084 -max_muxing_queue_size 1024

-hls_fmp4_init_filename "init-v-av01-2160p-av01.0.12H.10.m4s"
-hls_segment_type fmp4 -hls_playlist_type vod -movflags

Can somebody give me a hint why the SVT-AV1 encoder does not take the
information?
