Replace libffmpeg.so of opera version 54.0.2952.71 by the bundled file from opera version 68.0.3618.173
#! /bin/bash
rm -fr opera-get-ffmpeg-from-68.sh.tmp
TAB=" "
cat <<EOF
This script safely replaces the file libffmpeg.so from opera version
${TAB}54.0.2952.71
by the updated file from version
${TAB}68.0.3618.173
The old file is renamed to libffmpeg.so-..., with ... being the md5sum of
it's content, so in case something goes wrong you can easily revert.
This script tries to replaces the file in these directories:
EOF
# Configure all directories to search for libffmpeg.so:
opera_dirs=(
"/usr/lib64/opera"
)
# Configure all md5sums of old libffmpeg.so files we're going to replace
md5sums=(
"19915d948247726293aa1cf8a0bc4a2d" # 54.0.2952.71
)
# Leave this empty, it will be populated by the following loop
