<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 <replaceable>movie1.avi</replaceable> <replaceable>movie2.avi</replaceable> -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.

Don't forget to enable the repeat flag in <filename>.lircrc</filename> when

<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 usable remotely because they are
|
|
implemented at the demuxer level. It's sad for MF but TV stream would anyway
|
|
require an insane amount of bandwidth.

After having compiled <application>MPlayer</application> go to the

<application>make</application> to build the server binary.

You can then copy the <application>netstream</application> binary

<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 <replaceable>mpst://servername/vcd://2</replaceable>
|
|
</screen>
|
|
You can also access files on this server :
|
|
<screen>
|
|
mplayer -cache 5000 <replaceable>mpst://servername//usr/local/movies/lol.avi</replaceable>
|
|
</screen>
|
|
Note that paths which aren't starting with a / will be relative to
|
|
the directory where the server is running. The <option>-cache</option> 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 which are possible through this. Instead send
|
|
some (good) patch to make it better or start writing your own server.

<title>Edit Decision Lists (EDL)</title>

<para>
|
|
The edit decision list (EDL) system allows you to automatically skip
|
|
or mute sections of videos during playback, based on a movie specific
|
|
EDL configuration file.
|
|
</para>
|
|
|
|
<para>
|
|
This is useful for those who may want to watch a film in "family-friendly"
|
|
mode. You can cut out any violence, profanity, Jar-Jar Binks .. from a movie
|
|
according to your own personal preferences. Aside from this, there are other
|
|
uses, like automatically skipping over commercials in video files you watch.
|
|
</para>
|
|
|
|
<para>
|
|
The EDL file format is pretty bare-bones. Once the EDL system has reached a
|
|
certain level of maturity, an XML-based file format will probably be implemented
|
|
(keeping backwards compatibility with previous EDL formats).
|
|
</para>
|
|
|
|
<para>
|
|
The maximum number of EDL entries for the current incarnation of EDL is 1000.
|
|
If you happen to need more, change the <systemitem>#define MAX_EDL_ENTRIES</systemitem>
|
|
in the <filename>edl.h</filename> file.

<para>
|

Include the <option>-edl <filename></option> flag when you run
|
|
<application>MPlayer</application>, with the name of the EDL file you
|
|
want applied to the video.

<sect2 id="edl_making">

<title>Making an EDL file</title>
|
|
<para>
|
|
The current EDL file format is:
|
|
<programlisting>
|
|
[begin second] [end second] [action]
|
|
</programlisting>
|
|
Where the seconds are floating-point numbers and the action is either
|
|
<literal>0</literal> for skip or <literal>1</literal> for mute. Example:
|
|
<programlisting>
|
|
5.3 7.1 0
|
|
15 16.7 1
|
|
420 422 0
|
|
</programlisting>
|
|
This will skip from second 5.3 to second 7.1 of the video, then mute at
|
|
15 seconds, unmute at 16.7 seconds and skip from second 420 to second 422
|
|
of the video. These actions will be performed when the playback timer
|
|
reaches the times given in the file.
|
|
</para>
|
|
|
|
<para>
|
|
To create an EDL file to work from, use the <option>-edlout <filename></option>
|
|
flag. During playback, when you want to mark the previous two seconds to skip over,
|
|
hit <keycap>i</keycap>. A corresponding entry will be written to the file for
|
|
that time. You can then go back and fine-tune the generated EDL file.
