qtdefaults allows users to read, write, reset and delete QuickTime user preferences from a command line shell. The commands are as follows: read LegacyAudioCodecsEnabled Prints whether legacy audio codecs are enabled for use in the export settings. read LegacyVideoCodecs <videocodec> Prints whether the specified legacy video codec is enabled for use in the export settings. It will print "enabled" if the codec is enabled, "disabled" if disabled, or "unrecognized" if the codec is unknown. read LegacyVideoCodecs Prints list of legacy audio codecs currently enabled for use in the export settings. read InstalledLegacyVideoCodecs Prints out a list of all legacy video codecs installed in the current system. This list includes both enabled and disabled video codecs. These codec identifiers are used with 'qtdefaults read LegacyVideoCodecs' and 'qtdefaults write LegacyVideoCodecs'. read TransportSettings Prints the transport settings being used by QuickTime for streaming media. read MimeSettings Prints the MIME types currently being handled by the QuickTime plugin. read MediaKeys <category> Prints the media keys being used by QuickTime to playback encrypted movies. The optional <category> parameter can be used to list only the media keys associated with the specified category. reset DownloadCache Empties the cache being used by QuickTime to store downloaded content. reset TransportSettings Resets QuickTime to automatically determine the best protocol and port for streaming media. reset MimeSettings Resets QuickTime plug-in to handle the default MIME types. reset LegacyVideoCodecs Disables all QuickTime legacy video codecs. write LegacyAudioCodecsEnabled <value> A <value> of "yes" will enable the legacy audio codecs for use in the export settings and a <value> of "no" will disable them. write LegacyVideoCodecs <videocodec> <value> A <value> of "enabled" will enable the specified legacy video codec for use in the export settings and a <value> of "disabled" will disable it. write MediaKeys <category> <key> Adds the media key specified by <category> and <key> values to the list of media keys used to playback encrypted movies. write TransportSettings [protocol [port]] Sets QuickTime streaming to use the transport settings as specified by <protocol> and <port>. Following are the recommended values for <protocol> and <port>: - To use HTTP, specify <protocol> = HTTP and <port> = 80 - To use UDP, specify <protocol> = UDP and either <port> = 554 or <port> = 7070 delete MediaKeys <category> <key> Deletes the media key specified by <category> and <key> if it exists.
