Panic on basic encode of rgb48, 12 bpc images within ffmpeg #3435
Description
Describe the bug
ffmpeg nightly build is panicking while trying to encode rgb48/12 bpp image series.
To Reproduce
- Make test directory:
mkdir -p test && cd test - Generate random-ish samples:
for n in {0..2}; do convert -size 4946x3280 -depth 12 plasma:red-blue -gravity Center -pointsize 50 -fill green output_${n}.jxl & done; wait - Try to generate video:
RUST_BACKTRACE=full ~/opt/ffmpeg-master-static_noauto/bin/ffmpeg -y -hide_banner -start_number 1 -r 25 -i ./output_%d.jxl -pix_fmt yuv444p12le -c:v librav1e test.mp4
Expected behavior
We get some playable video.
