Package: webp
Version: 1.2.2-2
The `webp` package is missing several binaries which are built, but
which the upstream maintainers have classified as "examples". They are
anim_dump and anim_diff.
The binaries in "examples" in some cases conflict with the normally
installed binaries (e.g. cwebp, dwebp). These are the only two exceptions:
fred@mapache:~/Downloads/libwebp-1.2.4$ LIBWEBP_SET=$(find
examples/.libs -executable -type f | grep -Po '/[a-z0-9_]*?$' | cut -c
2- | sort -h); DPKG_SET=$(dpkg -L webp | grep /usr/bin/ | grep -Po
'/[a-z0-9_]*?$' | cut -c 2- | sort -h); diff <(cat <<< $DPKG_SET) <(cat
<<< $LIBWEBP_SET)
0a1,2
> anim_diff
> anim_dump
These binaries are highly useful because `webpmux`, one of the installed
binaries, cannot render an animation as it is, and doesn't handle frame
disposal or offsetting properly.
With these binaries, I can make a pipeline to convert WebP animation to
MP4 easily:
#!/bin/bash
anim_dump -folder /tmp/webp -tiff input.webp && \
ffmpeg -f tiff -f lavfi -i "color=white" -i /tmp/webp/dump_%04d.tiff
-c:v h264_nvenc -r 30 -qp 0 \
-pix_fmt yuv420p -filter_complex
"scale2ref,overlay=shortest=1,setsar=1,scale=max(320\,iw):-1" -y \
/tmp/webp.mp4
Without them, I can't. Please consider fixing this oversight — thank you!
