ffmpeg error

Hi friends, today I found that I have a strange error when I was try to update openshot...after this update with sbopkg, when I start openshot-qt in terminal I see this errors:

Code:

  logger:ERROR Traceback (most recent call last):

      logger:ERROR ImportError
      logger:ERROR :
      logger:ERROR libx265.so.151: cannot open shared object file: No such file or directory

After ffmpeg:

Code:

ffmpeg: error while loading shared libraries: libx265.so.151: cannot open shared object file: No such file or directory

but I have libx265.so.160 in /usr/lib64 not 151 and I have all the .so files that I checked with yes when configure ffmpeg before few months and then everything was ok??
my OS is SLackware 14.2 64 bit current
Sorry for my english skills

I think this means your ffmpeg install needs to be rebuilt.

bodqhrohro · 07-08-2018, 11:21 AM

In case of a slight version mismatch, you may try just to symlink an old version to a newer one. I did it for some proprietary software that was built against the certain versions of libraries, and it worked well. However, there always is a chance of segfaults or more extraordinary bugs if signatures of some exported functions changed in the new version.

orbea · 07-08-2018, 11:30 AM

I would strongly suggest that no one follows the above solution. Its a poor hack that has a lot of potential to cause issues, especially later when the hack has been forgotten about.

In this case recompiling ffmpeg will probably work. In the event where recompiling the program is not possible such as a proprietary program and the old library is really needed, then supplying it in a package like aaa_elflibs would be better.

Ok guys, I recompiled ffmpeg and now after ffmpeg:

Code:

Use -h to get full help or, even better, run 'man ffmpeg'

But new version of libopenshot can't compile and give this error:

libopenshot:
Would you like to continue processing the rest of the
queue or would you like to abort?  If this failed
package is a dependency of another package in the queue
then it may not make sense to continue.

Seems like look for old version libx265.so but I don't have this .so file. I don't understand programming but I try find in make files in /tmp/Sbo/libopenshot something with "libx265.so.151" and hard replace with "libx265.so.160", but I can't find anything like this..

Code:

~# locate libx265.so
/usr/lib64/libx265.so.160
/usr/lib64/libx265.so

Thanks in advance

Code:

you have installed manually ffmpeg in /usr/local and the build is finding that instead of the one you packaged.

orbea · 07-08-2018, 12:09 PM

Your error message indicates you still have the old ffmpeg installed. Did you happen to use installpkg instead of upgradepkg? If so I would suggest using removepkg on all installed ffmpeg packages and then reinstalling the correct one.

Alternatively there is still another program on your system that needs to be recompiled. This script is somewhat slow, but should help point out what those programs are as it will ldd your entire system and report missing libraries.

Aaah yes yes...I forgot that in some moments of madness I just cp some files from /usr/lib64 to /usr/local/lib64 trying to fix everything without rebuild..now I just remove them and everything is ok..
Thanks to all
