Bug report - [ffmpeg error while loading shared libraries: libx264.so.152: cannot enable executable stack as shared object requires: Permission denied]

[severnaside]

Describe the bug

I installed Ubuntu using UserLAnd on my Android phone. Then I installed get-iplayer from the get-iplayer PPA. After that, I checked if ffmpeg will run, but got the above error.

Steps to reproduce the behavior:

Type the following commands: sudo apt install -y software-properties-common sudo add-apt-repository ppa:jon-hedgerows/get-iplayer sudo apt update sudo apt install get-iplayer ffmpeg -h

Device Information

Device: [Moto G4 Plus].
Android Version: [7.0].
UserLAnd Version [2.6.5].
Device is not rooted.
Device is not running LineageOS

Please add any other context you think might help us resolve your issue. I fixed the problem by installing execstack and running queries. The stack execute bit is set for these files: /usr/lib/arm-linux-gnueabihf/libx264.so.152 /usr/lib/arm-linux-gnueabihf/x264-10bit/libx264.so.152 I cleared the executable stack flag with commands e.g.: sudo execstack -c /usr/lib/arm-linux-gnueabihf/libx264.so.* This enabled ffmpeg to work correctly. Do you need these flags set during installation of your application? If not, it would be safer if you removed the flags from these libraries.

I did a fresh install of Ubuntu. With no additional packages installed, the above file libx264.so. is not present. I then installed only the package ffmpeg. After that, the ffmpeg error appears when running ffmpeg, referring to libx264.so. The same error occurs using Debian on UserLAnd. Maybe this is not a UserLAnd problem, but hopefully you can shed some light.

How to Fix For Stremio?

I have Debian using userland, I made a project where I try to create moving stickers as fixed ones in a JavaScript script: First I tried to use wa-sticker-formatter but it requires sharp which is not available for armv7 platforms, so I wanted to use the old reliable ffmpeg, but it turns out that when installing I get:

userland@localhost: $ sudo apt install ffmpeg Reading package lists... Done Building dependency tree... Done Reading state information... Done ffmpeg is already the newest version (7:4.3.6-0+deb11u1). The following packages were automatically installed and are no longer required: javascript-common libc-ares2 libjs-highlight.js Use 'apt autoremove' to remove them. 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. 6 not fully installed or removed.

using termux it simply lets you install ffmpeg using the pkg command and it doesn't fail, but here you have to use the apt package manager, so any solution?
