mplayer cannot be installed in current release
The current mplayer package (in 3.3) depends on:
Those versions are respectively provided by the packages:
which are both absent from 3.3, but present in 3.2.
The package should ideally be upgraded to depend on current versions of the dependencies.
As a side note, creating a symlink /usr/lib/libvpx.so.2 -> libvpx.so.3 is sufficient for the libvpx, but this workaround cannot be applied to the libx264.so.142 since this version of mplayer has `x264_encoder_open_142` in its dynamic symbol table (and that function is absent from the current version of the library).
The current workaround is as follow:
http://<mirror>.alpinelinux.org/alpine/v3.2/mainin your `/etc/apk/repositories file`.
- Install the mplayer package (with —allow-untrusted)
- Create a symlink /usr/lib/libvpx.so.2 ->libvpx.so.3
