Please try this as an user; $ rpm -e ffmpeg-3 This is supposed to return nothing. But, if you this; $ rpm -e libavformat57-3.4.2-150200.11.34.2 many dependency error messages should appear like these; error: Failed dependencies: libavformat.so.57.76()(64bit) is needed by (installed) libQtAV1-1.13.0-21.128.x86_64 libavformat.so.57.76()(64bit) is needed by (installed) libyami-utils-1.3.2-17.8.x86_64 libavformat.so.57.76()(64bit) is needed by (installed) libavdevice57_13-3.4.2-150200.11.34.2.x86_64 [...] These things are saying that your system only needs the libraries. Also, there is no exclusion relationship between the ffmpeg-3 and ffmpeg-4 libraries, so they can coexist. So, if you run # zypper in ffmpeg-4, ffmpeg-3 will be uninstalled while leaving the libraries behind, and ffmpeg-4 and its libraries will be installed automatically. In Tumbleweed, ffmpeg-4's libraries and ffmpeg-7, as well as its libraries coexist, and I think the cause is in vlc. In short, when we build vlc with ffmpeg-5 or later, vlc cannot play certain x264 codec videos, and a black screen will appear. Because of this problem, I think that Tumbleweed has a coexistence relationship. However, since leap 15.6 is considered to be based on ffmpeg-4.4.4, it seems that there is no need to have a coexistence relationship with ffmpeg 3.4.2, so I wrote that it was strange. There must be some circumstances, but I think that $ rpm -e libavformat57-3.4.2-150200.11.34.2 will tell you about it.
