Further discussion on the mailing list explored this topic, and
|
|
|
|
|
revealed that ELF symbol versioning is lacklusterly implemented in
|
|
|
|
|
ffmpeg, which can cause inadvertent mixing of library versions on
|
|
|
|
|
openSUSE, and precompiled Linux distributions in general. It is
|
|
|
|
|
unclear when upstream will have implemented a solution. Until then,
|
|
|
|
|
we will need to tighten the requirements between packages, to which
|
|
|
|
|
end we stretch the SOVERSION to include MINOR.

Programs linking to libavcodec get the right DT_NEEDED field with value
|
|
|
|
|
libavcodec.so.58.91, and so they do not request libavcodec.so.58 (which could
|
|
|
|
|
potentially lead to libavcodec.so.58.54).
|
|
|
|
|
Programs dlopening libavcodec.so.58 will get something random, that's
|
|
|
|
|
what dlopening programs have to deal with.
