Hi all! I would like to install a tool that doesn’t has an rpm version, so I downloaded the .deb version, converted with alien and tried to install.
The installer says that libavcodec.so.53()(64bit) is missing. I don’t think that’s true because I installed ffmpeg, and so many codecs… is it possible that there are problems with libavcodec location being the package originally a .deb?
Hi
Likely the codec version, what is the output from;
zypper se libavcodec
You may need a symlink to the version that is installed. Install mlocate, run
sudo updatedb
locate libavcodec.so
If there is one with a higher version number behind the so, create a symlink to the .so with the name libavcodec.so.53, it should not complain anymore.
But, are you sure there’s no rpm?
Agree that maybe an RPM build exists for your tool…
I wrote the following Wiki describing several ways I recommend for finding files and apps… Although I didn’t mention converting a DEB, I do mention as one of the last options finding the source and compiling it.

Thank you all guys, but i have another problem now: i can’t boot Opensuse because grub doesn’t show it. I’ve opened another thread, when i will solve this problem i will try your solutions

That’s the output 
/usr/lib64/libavcodec.so.56
/usr/lib64/libavcodec.so.56.60.100
/usr/lib64/libavcodec.so.57
/usr/lib64/libavcodec.so.57.107.100
/usr/lib64/libavcodec.so.58
/usr/lib64/libavcodec.so.58.18.100
That is the output for the “locate” command… how can i create a symlink? Thanks!
The tool is https://salmanarif.bitbucket.io/visual/downloads.html. I’ve tried to find it in many differents ways, but i didn’t find rpm packages nor source code :’(
EDIT:
In the /usr/lib64/ directory i used these two commands
sudo ln -s libavcodec.so.58 libavcodec.so.53
sudo ln -s libavcodec.so.58 libavcodec.so.53\(\)\(64bit\)
…but nothing, i continue to have the same error…
Hi
All pretty straight forward…
This is all in my $HOME directory on Leap 15.1 and all as my user;
cd
mkdir -p Visual
mv visual_1.27-1_amd64.deb Visual/
cd Visual
ar -x visual_1.27-1_amd64.deb
ls
control.tar.gz data.tar.xz debian-binary visual_1.27-1_amd64.deb
tar xf data.tar.xz
ls
control.tar.gz data.tar.xz debian-binary usr visual_1.27-1_amd64.deb
usr/local/bin/visual/VisUAL.sh
Oct 27, 2019 6:12:28 PM java.util.prefs.FileSystemPreferences$1 run
INFO: Created user preferences directory.

Linux
Result…
Note: Only default oss/non-oss and update repos added and libavcodec57 installed only.
Perrrrfect, i followed your commands and all wark without any problems… the only problem is that i’m obviously stupid because it was simple (i suppouse) lol!
Can you explain what i did? I simply “unpackaged” the .deb package?
Hi
Not sure, but you used alien to convert the deb file 
I think it doesn’t have the logic sometimes…
There are some folders the application is looking for, perhaps the never made it to the correct place…
Sometimes easier to install/run as your user, probably with some additional foo a spec file could be created to install as an rpm, but alien would not be able to do this.
If you copy the usr/share/applications/VisUAL.desktop to ~/.local/share/applications directory and then manually edit the paths to point at the script and icon it will appear in your desktop menu system;
Exec=/home/<yourusername>/Visual/usr/local/bin/visual/VisUAL.sh
Icon=/home/<yourusername>/Visual/usr/local/bin/visual/icon.png
\It does need to be the full path…
I should read your message first this morning… i spend much time to create a working menu link with icon… i just used “~/”, and after many tries i knew that it wants full path lol!
Have a nice day!
