Advanced section

This section contains various options that affect advanced command line parameters passed to MPlayer, as well as interaction with KDE I/O Slaves.

Executable path: This option tells KPlayer where to find the MPlayer executable. It is either an absolute path or a name to look for in the current environment path.
Additional command line arguments: This option gives additional options that will be passed to MPlayer on the command line. See the MPlayer manpage for a complete list of possible options. You can also set this option for an individual file or URL in the File Properties.
Preferred demuxer: This option lists the available demultiplexers and lets you choose the one to be used for decoding files and streams. Auto is the recommended choice, it lets MPlayer decide which demuxer to use automatically. If you need to tell MPlayer to use a particular demuxer for a particular file or stream, set this option in the File Properties.
Frame drop: If your system is too slow to play a file, MPlayer can drop some frames so playback does not slow down. The none option disables frame dropping, soft drops less frames, and hard drops more frames and may sometimes break decoding. You can also set this option for an individual file or URL in the File Properties.
Cache: This option lets you choose whether to use cache and set its size. The auto option lets MPlayer choose an optimal cache size automatically, none tells MPlayer to use no cache, and set size lets you set a specific size. You can also set this option for an individual file or URL in the File Properties.
Build new index: This option lets you choose whether to build a new index for seeking. The yes option builds an index if the file does not have it, no tells MPlayer not to build an index, and force tells it to always build an index. You can also choose this option for an individual file or URL in the File Properties.
Use temporary file for playing from KIOSlave: This option lets you choose whether to use a temporary file for playing from KDE I/O Slaves. This option has no effect for URLs passed directly to MPlayer. You can also choose it for individual file or URL in File Properties.
Use KIOSlave for HTTP: This option lets you choose whether to use a KDE I/O Slave to play HTTP URLs. You can also choose this option for individual file or stream in File Properties.
Use KIOSlave for FTP: This option lets you choose whether to use a KDE I/O Slave to play FTP URLs. You can also choose this option for individual file or stream in File Properties.
Use KIOSlave for SMB: This option lets you choose whether to use a KDE I/O Slave to play Samba URLs. You can also choose this option for individual file or stream in File Properties.
