    If you want to resume playback at a later time, it is sufficient to call =strm= without arguments.
+   Use the =--tidy= flag to not resume playback.
 
    Resuming playback of a file over multiple machines is only possible if all machines are configured with the same =media_directory= path for the file.
    This is due to the fact that mpv stores the playback positions based on the filename hash, which in the case of remote files is the entire file path.
