----------------------------------------
ds_get_regfilters (*string category_guid) -> propList | list
----------------------------------------
When called without without argument, a proplist ["<guid>": filtername, ...] of all registered
DirectShow filters is is returned. Notice: properties are not unique, some filters like e.g. ACM
and VCM codecs don't have a unique GUID, for all of them the same GUID of the corresponding
DirectShow Wrapper Filter will be returned as property.
When called with category_guid, a list [filtername, ...] of registered DirectShow filters that
belong to this category is returned.
Arguments:
- *category_guid
Returns: propList | list
----------------------------------------
ds_register_filter (*string filterfile) -> HRESULT
----------------------------------------
Registers the specified filter (or COM Components/DLL Servers/ActiveX Control).
Same functionality as regsvr32.exe <filterfile>.
If no filterfile is specified, the function registers the 3 special filters
of the Xtra file (DirectShow.x32) in the system (see also paragraph "3.) Special Filters").
Requires the projector to be run with admin privileges!
In Windows Vista and later (Win 7/8/10) you can alternatively use Shell Xtra (v1.11+) and
code like this to trigger a "Run as Adminstrator"/UAC prompt from within Director:
if filterfile contains SPACE then filterfile = QUOTE&filterfile"E
props = [:]
props["operation"] = "runas"
props["wait"] = 1
props["parameters"] = "/s" && filterfile
exitCode = shellXtraInstance.shell_execex("regsvr32.exe", props)
success = (exitCode=0)
Arguments:
- *filterfile -- path to filter to be registered
Returns: HRESULT
----------------------------------------
ds_unregister_filter (*string filterfile) -> HRESULT
----------------------------------------
Unregisters the specified filter (or COM Components/DLL Servers/ActiveX Control).
Same functionality as regsvr32.exe /u <filterfile>.
If no filterfile is specified, the function unregisters the 3 special filters
of the Xtra file (DirectShow.x32) in the system (see also paragraph "3.) Special Filters").
Requires the projector to be run with admin privileges!
In Windows Vista and later (Win 7/8/10) you can alternatively use Shell Xtra (v1.11+) and
code like this to trigger a "Run as Adminstrator"/UAC prompt from within Director:

props = [:]
props["operation"] = "runas"
props["wait"] = 1
props["parameters"] = "/s /u" && filterfile
exitCode = shellXtraInstance.shell_execex("regsvr32.exe", props)
success = (exitCode=0)
Arguments:
- *filterfile -- path to filter to be unregistered
Returns: HRESULT
----------------------------------------
ds_error_info (integer errornumber) -> list
----------------------------------------
Arguments:
- errornumber -- HRESULT returned by some function
Returns: list -- [string error_name, string error_description]
----------------------------------------
ds_setcurrentdir (string dir) -> VOID
----------------------------------------
Sets current directory. This can be useful for (un)registering certain filters that depend on
external DLLs (like e.g. MainConcept's mcaacenc.ax). Those filters can only be registered if
both the filter and the DLL are in the current directory (or somewhere in the system path)
Arguments:
- dir -- path to directory
Returns: VOID
--**************************************
-- SPECIAL FILTER FUNCTIONS

ds_dump_set_callback (ymbol callbackHandler, *callbackTarget
ds_dump_start (*bufferSize
ds_dump_stop ()
ds_audiosource_start (*bufferSize)

--**************************************
-- SUBTITLES (based on DirectVobSub/VSFilter)
--**************************************
----------------------------------------
ds_subtitles_load object me, string subtitleFile -> HRESULT
----------------------------------------
Loads a subtitle file (e.g. SRT) into the current filter graph. This only works if the filtergraph
either contains a VSFilter or VSFilter_autoload filter.
Returns: HRESULT
----------------------------------------
ds_subtitles_get_filename object me -> string | VOID
----------------------------------------
Returns the full path to the subtitle file that the xtra instance currently uses. If the current
filter graph contains a VSFilter/VSFilter_autoload filter, but no subtitle file is loaded, it
returns an empty string. If the graph doesn't contain any VSFilter/VSFilter_autoload filter, VOID is
returned.
Returns: string | VOID
----------------------------------------
ds_subtitles_hide object me, integer hideFlag -> HRESULT
----------------------------------------
Changes the visibility of subtitles: if hideFlag is TRUE, subtitles are hidden, otherwise shown.
This only works if the filter graph either contains a VSFilter or VSFilter_autoload filter.
Returns: HRESULT
----------------------------------------
ds_subtitles_set_position object me, integer overrideFlag, integer x, integer y -> HRESULT
----------------------------------------
Changes the position of subtitles in the video. 'overrideFlag' is a boolean and should usually be
set to TRUE (I'm not sure what setting it to FALSE actually means - it's an existing argument in the
VSFilter/DirectVobSub interface). x and y are percentage values, i.e. in the range 0-100. They
indicate the ratio of the bottom center of the subtitles relative to the width and height of the
video rect.
The function only works if the current filter graph either contains a VSFilter or VSFilter_autoload
filter. Changes are only applied after loading a new SRT file.
Returns: HRESULT
----------------------------------------
ds_subtitles_set_style object me, string fontface, object color, integer shadowFlag, integer outlineFlag, integer height, integer width, integer weight -> HRESULT
----------------------------------------
Changes the visual style of subtitles. For details on the parameters height, width and weight, see
https://msdn.microsoft.com/en-us/library/dd145037(v=vs.85).aspx
This only works if the current filter graph either contains a VSFilter or VSFilter_autoload filter.
Changes are only applied after loading a new SRT file.
Returns: HRESULT
----------------------------------------
ds_adjustImageGetRange object me, integer flag -> propList or HRESULT
----------------------------------------
This function only works if the VMR-9 video renderer is used in the current graph, otherwise it will
return E_FAIL.
If successful, it returns details about the supported range of the image property specified by flag,
it returns a property list with the 4 properties "MinValue", "MaxValue", "DefaultValue" and
"StepSize", all corresponding values are floats.
Note: the ranges can be hardware/GPU specific, but for a specific hardware it's fixed, so there is
no need to call the function multiple times.
Parameter 'flag' has the following meaning:
1 means Brightness
2 means Contrast
4 means Hue
8 means Saturation
Example:
-- get supported range for 'Brightness'
put gDX.ds_adjustImageGetRange(1)
["MinValue": -100.0000, "MaxValue": 100.0000, "DefaultValue": 0.0000, "StepSize": 0.1000]
Returns: either property list, or error code as negative integer (HRESULT)
----------------------------------------
ds_adjustImageGetValue object me, integer flag -> float or HRESULT
----------------------------------------
This function only works if the VMR-9 video renderer is used in the current graph, otherwise it will
return E_FAIL.
If successful, it returns the current value (as float) of the image property specified by flag, see
ds_adjustImageGetRange() for the meaning of this flag.
Example:
-- get current 'Contrast' value
res = gDX.ds_adjustImageGetValue(2)
if floatP(res) then
put "Contrast:", res
else
put "Error:", gDX.ds_error_info(res)
end if
Returns: either float, or error code as negative integer (HRESULT)
----------------------------------------
ds_adjustImageSetValue object me, integer flag, float val -> HRESULT
----------------------------------------
This function only works if the VMR-9 video renderer is used in the current graph, otherwise it will
return E_FAIL.
The function tries to change the current value (float) of the image property specified by flag, see
ds_adjustImageGetRange() for the meaning of this flag. If successful, it returns 0, otherwise an
error code as negative integer (HRESULT).
Example:
-- change current 'Saturation' value
hr = gDX.ds_adjustImageSetValue(8, 10.0)
Returns: HRESULT (0 = no error)
3.) Special Filters
===================
----------------------------------------
-- SPECIAL FILTERS
----------------------------------------
This version of DirectShow Xtra provides 3 special DirectShow filters.
These filters allow to use Director as source and target for audio and video in
DirectShow filter graphs.
The filters can be registered/unregistered in the system either with
a) running
regsvr32.exe DirectShow.x32
regsvr32.exe /u DirectShow.x32
in a DOS box, or by
b) calling
-- without argument!
DSXtraInstance.ds_register_filter()
DSXtraInstance.ds_unregister_filter()
via lingo.
Note:
Registering/unregistering needs admin privileges, so if not admin/under UAC you
have to run the *.bat files (or the Projector, if using ds_register_filter...)
as admin by selecting "Run as Administartor" fom the Explorer's context menu.
The 3special filters are:
- DS Xtra Dump Filter
- DS Xtra AudioSource Filter
- DS Xtra VideoSource Filter
Corresponding GUIDs are:
- CLSID_DSXtraDumpFilter = "36a5f770-fe4c-11ce-a8ed-00aa002feab5"
- CLSID_DSXtraAudioSourceFilter = "BFBC37B0-20B1-43CE-B7AB-6DCD080D1E46"
- CLSID_DSXtraVideoSourceFilter = "9A80E195-3BBA-4821-B18B-21BB496F80F8"
Details:
a) DS Xtra Dump Filter
A general purpose sink filter that accepts arbitrary data types and passes that
data (as bytearray) to a lingo callback handler. Demo "dump.dir" ("dump.exe")
shows how you can use it to receive input from an arbitrary audio source (e.g. a
microphone, a TV/Radio tuner or an audio or video file) and either record it to
memory or to an external WAV file, or directly play it using director's (new)
sound engine.
b) DS Xtra AudioSource Filter
Allows to use Director as audio source in filter graphs. Audio data is passed as
bytearray to function ds_audiosource_set_sound(). Demo "audiosource.dir"
("audiosource.exe") shows how this can be done automatically by using the
Director's registerByteArrayCallback function to automatically pass the output
of a currently playing Sound object.
c) DS Xtra VideoSource Filter
Allows to use Director as video source in filter graphs. Video data is passed
frame-wise as lingo images to ds_videosource_set_image(). All images are
(obviously) required to have the same dimensions, and currently ONLY 32-bit
images are supported. Width, height and the output video's framerate have to be
passed to function ds_videosource_start().
