It seems slightly risky to me to call exit_player for an init function.
It tends to rely on some state that might not be set up correctly at
that point for example.
Also it will not exit if the AO is fine, but e.g. we cannot actually
connect to it since it doesn't support any format we can convert to
for example.
It might work better adding the code to reinit_audio_chain, in the
init_error label?
For video, the equivalent would be reinit_video_chain, and it behaves
quite similar.
