<application>MPlayer</application> utilizes a complex playtree. It consists
|
|
of global options written as first, for example
|
|
|
|
<screen>mplayer -vfm 5</screen>
|
|
|
|
and options written after filenames, that apply only to the given
|
|
filename/URL/whatever, for example:
|
|
|
|
<screen>mplayer -vfm 5 movie1.avi movie2.avi -vfm 4</screen>
|
|
</para>
|
|
|
|
<para>
|
|
You can group filenames/URLs together using <literal>{</literal> and
|
|
<literal>}</literal>. It's useful with option <option>-loop</option>:
|
|
|
|
<screen>mplayer { 1.avi -loop 2 2.avi } -loop 3</screen>
|
|
|
|
The above command will play files in this order: 1, 1, 2, 1, 1, 2, 1, 1, 2.

<para>

Remote streams allow you to access most <application>MPlayer</application>
|
|
stream type from a remote host. The main purpose of this feature is to make
|
|
it possible to directly use the CD or DVD drive of another computer on the
|
|
network (provided you have the required bandwidth). On the downside some
|
|
stream type (currently TV and MF) are not useable remotely because they are
|
|
implemented at the demuxer level. It's sad for MF but TV stream would anyway
|
|
require an insane amount of bandwith.

<title>Using remote streams</title>
|
|
<para>
|
|
First you have to start the server on the computer you intend to remotely
|
|
access. Currently the server is very basic and doesn't have any commands
|
|
line arguments so just enter <filename>netstream</filename>. Now you can
|
|
for example play the second track of a VCD on the server with :
|
|
<screen>
|
|
mplayer -cache 5000 mpst://servername/vcd://2
|
|
</screen>
|
|
You can also access files on this server :
|
|
<screen>
|
|
mplayer -cache 5000 mpst://servername//usr/local/movies/lol.avi
|
|
</screen>
|
|
Note that paths wich aren't starting with a / will be relative to
|
|
the directory where the server is running. The cache option is not
|
|
needed but highly recommended.
|
|
</para>
|
|
|
|
<para>
|
|
Be aware that currently the server is not secure at all. So don't complain
|
|
about the numerous exploits wich are possible through this. Instead send
|
|
some (good) patch to make it better or start writing your own server.
