obs studio fails

JinxsDad · 06-04-2023, 09:05 AM

I'm using (or rather, trying to use) OBS Studio from Alien Slackbuilds. Just one problem: it fails every time I try to run it, complaining about a missing shared library, libavcoded.so.59. If I try
the one from the OBS Studio site, it fails due to another shared library (forgot which, sorry). I
tried installing the latest ffmpeg (other conversations suggested that libavcodec should be in ffmpeg. No such luck.

So, hopefully this is a simple enough question: Where do I get this shared lib?

System info:

Btw, the hostname is supposed to be JinxsSlack, but somehow it turned into that one, and nothing seems to want to let me fix it. But that's another topic for a different post.

Thanks

Did you mean "libavcodec.so.59"? It appears you are running Slackware 15.0 based on the kernel version you posted.

Try replacing the base ffmpeg-4.4.1 with ffmpeg-5.1.2 from alien slackbuilds.

You could look for a needed file like so:

Code:

slackpkg file-search libavcodec.so.59


NOTICE: pkglist is older than 24h; you are encouraged to re-run 'slackpkg update'

Looking for libavcodec.so.59 in package list. Please wait... DONE

The list below shows the packages that contains "libavcodec\.so\.59" file.

[inst] restricted  : ffmpeg-5.1.2-x86_64-1alien
[mask] alienbob    : ffmpeg-5.1.2-x86_64-1alien
[mask] slackware64 : ffmpeg-5.1.2-x86_64-2

You can search specific packages using "slackpkg search package".

Any day you learn something new is an awesome day. Thanks for making this an awesome day for me. :-)

Edit: Now I can fix other things missing shared libs (like disk manager, with which I can format and hopefully be able to use an old 4 TB USB drive. Then I convert two old NTFS drives to ext-4.)

Ok, so I had to reload the page because of some token, and now my post is gone.

So here's the summary: uninstall for vokoscreenNG didn't just remove its directory (e.g. ...../..../.../vokoscreenNG ... oh no ... it removed /usr/bin.

So now, after some serious extra backups (I back up MY home directory, not the system), I'm hoping the live CD/DVD install disk has a repair option that
can at least rebuild the original /usr/bin/.

If not, and I'll check back here after doing my current backups including /etc and Firefox (after I find where its profile stuff is and back it up) and see
if there are any suggestions. Otherwise, as far as I know, it's going to be full reinstall time. :-{

Suggestions?

After finally getting an install image to boot and do a clean install of Slackware 15, some strange things happened. First, not being able to use cpio, I used tar for backups. But tar did some crazy stuff. It backed up a ~/calendar file that doesn't exist instead of mine, selectively ignored stuff, etc. So I'm rebuilding from old backups. Good thing, though: I no longer need to be logged in as root to mirror displays. Same DVD iso file, same full install, vastly different results (sharing displays is not the only thing working now that wasn't before). STRANGE...... Must be the full moon. :-)

Another thing that works in this second full install that didn't in the first; OBS Studio.
Now I'm just installing apps and trying to either find my old (was my version before) and make it use my profile from before, or find a way to force the much newer one to use it, including extensions. Any less is totally UNSAT.
