The information on this tab is intended for advanced users
who are supposed to know the basic principles of how DirectShow
works.
Here you can configure the procedure of building the DirectShow
graph. It can be used when the standard procedure is unable
to build the graph correctly for a particular type of files
or when you need to use additional filters (for instance,
various DSP filters, etc.) that are not used by default
for some reasons.
For you to be able to configure the procedure of building
the graph Tray Player has the so-called graph building
rules that allow you to change the procedure for a certain
type of files.
Each rule consists of two sets of DirectShow filters (for
the Normal and Fail-safe modes) the player will try to
use while building the graph.
The following categories of filters can be specified in
each set:
|
Category
|
Purpose
|
|
Source filter
|
Here you can specify the filter that will be responsible
for reading data from a file (stream). For example,
the Windows Media source filter or the WinAmp Source
filter that allows you to use WinAmp input plug-ins.
|
|
General filters
|
The list of filters added to the graph after the
source filter is successfully added. For instance,
it can be some nonstandard parser.
|
|
Audio filters
|
The list of filters added to the graph in case the
file contains audio data. For instance, it can be
some nonstandard decoder or a DSP filter.
|
|
Audio renderer
|
Allows you to specify the Audio renderer filter.
|
|
Video filters
|
The list of filters added to the graph in case the
file contains video data. For instance, it can be
some nonstandard decoder or a filter for post-processing
video.
|
|
Video renderer
|
Allows you to specify the Video renderer filter.
|
If the sets of filters are different for the Normal and
Fail-safe modes and the player fails to build the graph
in the Normal mode it tries to do it for the second time
in the Fail-safe mode.
Tray Player contains a set of built-in rules that allow
you to solve typical problems occurring in the process
of working with files of widespread types. Such rules are
quite easy to activate. It is also possible to create your
own rules, but we will not dwell on this possibility. We
think that if the user has a deliberate J wish
to create his own rule, he will easily cope with the interface.
Built-in rules are quite enough for most users.
As an example, let us take a built-in rule:
This rule works for files of any type. The set of filters
is empty in the Normal mode and it means that the standard
procedure is used for building the graph. WinAmp Source
is specified as the Source filter in the Fail-safe mode.
It means that if the standard way of building the graph
fails, the player will try to use the WinAmp Source filter.
Another example:
This rule works for MP3 files. WinAmp Source is specified
as the Source filter in the Normal mode. It means that
the player will first try to use the WinAmp Source filter
for MP3 files and only in case of a failure the standard
procedure will be applied.
Along with rules, it is also possible to specify Common
filters added to the graph for all file types in Tray Player.
You can specify the following categories described above
in the set of Common filters: General filters, Audio filters,
Audio renderer, Video filters and Video renderer. It is
convenient to use Common filters for adding various additional
filters to the graph (e.g. DSP filters, etc.) and for specifying
the Audio renderer (thus you can select the sound card
you want if there are several sound cards on your computer).
You can see the rule (with Common filters taken into account)
used for building the graph for a particular file on the Graph
building tab of its File properties dialog
box.
