* commit '48a5adab':
  lavfi: add avfilter_init_str() to replace avfilter_init_filter().

avfilter_graph_create_filter() opaque is still passed to avfilter_init_filter()
which continues to pass it to init_opaque as its still used in the buffer sinks
the sinks should be changed and the opaque passing removed

Using the first names of authors sounds somewhat unprofessional
and might be considered offensive which is not intended.
The new names use the initials of the authors due to simplicity
and the possibility to apply it consistently without the need
to find political correct names for each future case where
alternative codecs might exist. Also its shorter ...

If someone has a better idea, like maybe 2 random letters
and people prefer it then iam happy to switch to that ...
