Both patches are required to fix out of memory scenario with this use case:
#!/usr/bin/env bash
which ffmpeg
if [ $# -lt 1 ] ; then
echo "Usage: ${0} INPUT"
echo "Example input can be generated with: "
echo " ffmpeg -v verbose -filter_complex
'testsrc2=r=25:s=640x480:d=470[out]' -map '[out]' -c:v libx264 -preset
superfast test_clip.mp4"
exit 1
fi
INPUT="${1}"
COPY_OUTPUT="${INPUT}_copy.mp4"
IMG2_OUTPUT="${INPUT}_img2.jpg"
echo "Input: ${INPUT}"
# if you get ooms, feel free to utilize ulimit
# (ulimit -v 5000000 && )
valgrind --tool=massif --massif-out-file="massif.out.$(date -Iseconds)" \
ffmpeg \
-y -ignore_unknown \
-v verbose \
-i "${INPUT}" \
-c copy -map 0 \
-t 470 \
"${COPY_OUTPUT}" \
-filter_complex
'[0:0]split=1[thumb_in];[thumb_in]trim=start=420:end=421,scale=720:-2:threads=1,setsar=1/1,hqdn3d,unsharp[thumb_out]'
