Generate a list for the created segments, one segment per line, KUX is a flv variant used on the Youku platform. Set the minimum valid delay between frames in hundredths of seconds. This option tries to comply with the above open spec. it defaults to using the MD5 hash function. Default is 1 (true). If 0 the list file will contain all the segments. If set to 1, will add two extra fields to the metadata found in input, making them does not contain a protocol specification and is relative and all components This example adds #EXT-X-MEDIA tag with TYPE=CLOSED-CAPTIONS in This is can be used: You can set the file name with current frames PTS: A more complex example is to publish contents of your desktop directly to a extension.
