AppImage doesn't work

[baimafeima]

I downloaded the latest AppImage file but it doesn't run after I made it executable. Can someone else test whether it's because of the AppImage or my system?

[coslyk]

Hello @baimafeima , could you post the output in terminal?

[baimafeima]

How could I launch an AppImage from the terminal to check its output?

[coslyk]

@baimafeima Run ./xxx.AppImage just like other executable files

[baimafeima]

Then I get the error report: bash: Run: command not found...

[baimafeima]

Thanks, then I get this error message: ./MoonPlayer-x86_64.AppImage: error while loading shared libraries: libjack.so.0: cannot open shared object file: No such file or directory

[baimafeima]

Is it related to my operating system or the AppImage is not working on other systems too?

[coslyk]

Can you try installing libjack on your system?

[coslyk]

I have repacked it and uploaded to the release page. Try downloading Moon_Player-1.9.2.glibc2.17-x86_64.AppImage ?

[baimafeima]

The latest Moon_Player-1.9.2.glibc2.17-x86_64.AppImage unfortunately doesn't work either. Memory is suddenly up to 2.45 GiB when I usually only need around 700. Libjack is not in the repository of my operating system, so I have no way of installing it.

[coslyk]

Can you tell me which Linux distribution you are using?

[baimafeima]

I'm using Solus. Some time ago, I've actually tried to have Moonplayer included into their repositories. You can find the issue here.

[coslyk]

As I googled, the package jack-audio-connection-kit on Solus contains libjack. Try installing it? If this doesn't work, try installing mpv, then all dependencies should be sufficient.

[baimafeima]

I installed both jack-audio-connection-kit and mpv but now I get - after typing ./Moon_Player-1.9.2.glibc2.17-x86_64.AppImage this error:

/tmp/.mount_Moon_PBaGRYf/usr/bin/moonplayer: error while loading shared libraries: libkeyutils.so.1: cannot open shared object file: No such file or directory

[coslyk]

Please install all the missing libraries according to the terminal output until all the dependencies are sufficient. You can use Google to find out the name of packages which contain the libraries.

[baimafeima]

I cannot find these libraries in my operating system. Installing them separately could potentially break my system. I thought they should all be bundled in the AppImage itself?

[coslyk]

The AppImage is bundled automatically by linuxdeploy-qt, it seems that this tool that it can't bundle all the dependencies correctly. In this case you'd better to compile it by yourself.

[baimafeima]

@probonopd Would you have an idea how this can be solved? Does the AppImage bundled through linuxdeploy-qt work on your machine? Many thanks in advance.

[probonopd]

@probonopd Would you have an idea how this can be solved?

The AppImage needs to bundle any library that cannot be expected to be there on each target system by default.

Does the AppImage bundled through linuxdeploy-qt work on your machine?

You can watch the test log at https://github.com/AppImage/appimage.github.io/pull/870

[coslyk]

After reading the source code I found that some libraries are automatically excluded by the AppImage building tools, because most of the Linux distributions include them and they need to be compatible with your platform, e.g. driver files. Bundling them into AppImage may cause the program not work.

There is a list of them: https://github.com/AppImage/AppImages/blob/master/excludelist

So if these libraries are not installed in your system, you should install them yourself.

As I googled the package keyutils contain the libkeyutils on your system.

[probonopd]

So if these libraries are not installed in your system, you should install them yourself.

These libraries are on the list because they are assumed to be part of every system. On which kind of system are they missing?

[baimafeima]

@probonopd I'm on Solus.

[probonopd]

Maybe you can suggest in their bug tracker to install the libraries listed on https://github.com/AppImage/AppImages/blob/master/excludelist by default in order to maximize out-of-the-box compatibility with many AppImages. Thanks.

[coslyk]

I just repacked the AppImage to include libkeyutils.

[baimafeima]

@probonopd My account on their development tracker was suspended as they don't like my political position on anti-censorship and freedom. It's a pity that they don't get politics right but after all they are a technically fascinating Linux distribution. So unfortunately, I cannot help with that but it would be great if you could do that as you are the main developer. @coslyk Thanks for your continued efforts to help getting Moonplayer to work on Solus. Where can I download the latest AppImage to test it?

[coslyk]

I don't understand what you mean by saying "political position". I believe that no one will refuse your feedback just because of this.Maybe because they think that this software may lead to copyright problems. As a tool MoonPlayer can't inspect whether the video is copyright, users should inspect it themselves. You can explain to them that MoonPlayer is something just like youtube-dl.The repacked AppImage is available on the Download page.

[baimafeima]

@coslyk Yes, exactly. This is what I explained and in addition to that it allows users to not be tracked by nasty cookies. At least I hope so. Unfortunately, my comment was deleted and shortly thereafter my account frozen. Maybe they had a bad day. See: https://dev.getsol.us/T5565

[coslyk]

@baimafeima Flatpak released: https://flathub.org/apps/details/com.github.coslyk.MoonPlayer

[probonopd]

@coslyk is there a working AppImage now?

[coslyk]

@probonopd You can try this: https://github.com/coslyk/AppImageCollection/releases/download/init/MoonPlayer-2.7-x86_64.AppImage

But the libva is not backward compatible, the hardware decoding may not work, so I don't recommend to use the AppImage version here (T_T)

[probonopd]

Thank you. It does launch now.

[coslyk]

@probonopd Thank you for your test!

The packaged libva1 from Ubuntu xenial doesn't work on my host system, which use libva2 by default. It seems that they use different APIs. Do you have any idea to solve it?

[probonopd]

Are you running Wayland? (Just guessing here, I have no real clue about VO)

[coslyk]

@probonopd I'm using XWindow.

[probonopd]

Sorry I do not know then.

[coslyk]

Maybe this is a solution: https://voltaicforge.com/linux/steam-vaapi-fix-linux/#

We can make it prefer to use the host system's libva, if the host system doesn't have it then use the packaged one.

[probonopd]

Sounds good, worth trying.
