Ah, I can indeed reproduce the problem with: BR2_aarch64=y BR2_TOOLCHAIN_EXTERNAL=y BR2_TOOLCHAIN_EXTERNAL_BOOTLIN=y BR2_TOOLCHAIN_EXTERNAL_BOOTLIN_AARCH64_GLIBC_STABLE=y BR2_PACKAGE_OPENCV4=y BR2_PACKAGE_OPENCV4_WITH_WEBP=y but in this case, webp is already added as a dependency of opencv4. So your patch is not actually correct. What I guess happens is that we build webp without demux/mux support, so we're missing features. So I believe the correct fix is probably: diff --git a/package/opencv4/Config.in b/package/opencv4/Config.in index 47c1cf3f4a..e4a15f742b 100644 --- a/package/opencv4/Config.in +++ b/package/opencv4/Config.in @@ -369,6 +369,8 @@ config BR2_PACKAGE_OPENCV4_WITH_V4L config BR2_PACKAGE_OPENCV4_WITH_WEBP bool "webp support" select BR2_PACKAGE_WEBP + select BR2_PACKAGE_WEBP_DEMUX + select BR2_PACKAGE_WEBP_MUX help Enable WebP support. Remains to figure out since when this problem occurs. The 4.12.0 -> 4.13.0 bump of opencv4 in commit 33178c538541be224e49b5f548bd5404de3912fa ? But this one has been around for quite a while.
