[FFmpeg-devel] [PATCH v3 1/3] lavu/opt: Rename AV_OPT_FLAG_RUNTIME_PARAM to ...POST_INIT_SETTABLE_PARAM

[Andrew Sayers]

The old name could be misread as the opposite of "AV_OPT_FLAG_READONLY" -
some things can be set at runtime, others are read-only.  Clarify that
this refers to options that can be set after the struct is initialized.
