setLogLevel abstract method
Sets the minimum severity of log messages mpv emits on
PlayerStream.log at runtime (mpv_request_log_messages).
The initial level comes from PlayerConfiguration.logLevel; raise it (e.g. to LogLevel.debug) to surface more diagnostics on demand, or lower it to cut log volume. Synchronous, and valid before the player has finished starting: the level then applies once it has.
Implementation
void setLogLevel(LogLevel level);
