Media player plugin available for girder 4

[birty]

this is my first attempt to use DUI so it might not be perfect
http://www.birtles.org.uk/girder/CTMediaSetup2.8.exe
the setup also contains a DUI unit ported to delphi so if you are trying to develop a delphi plugin it might help

[Ron]

Congratulations, you are the first 3rd party plugin!

[birty]

wohooo, do i get a prize? :wink:

[Ron]

:-)

[birty]

now that i have the dui working, how do i make my settings screen part of the dui (im sure i read somewhere it was possible)
edit: i assume its pretty much the same as with command except you look for duOnHookConfig in gir_dynamic_ui, but how do you get the settings back into the plugin from the dui?

[curtiswren]

Did you figure out how to do this? I need to do the same thing. I've got the screen showing up in the settings dialog, but I'm not sure how to prefill it or get the settings when the apply button is pressed.

On a related note, how do we do similar things for a learn event dialog?

[birty]

you need to create an xml file using the dui designer but more than that i dont know

[Ron]

For the settings window basically you specify registry number or registry value. Look at plugins\UI\UIR.xml for an example. So set the registry to whatever default you plugin needs if there is nothing in there. When the user presses apply on that dialog you get a 'duOnApply' callback into the gir_dynamic_ui.

Sadly we don't have the DUI in place for the events. To prevent G4 from moving futher out into the future we decided not to implement that for the current release.

[birty]

new version released with lots of changes:

http://www.birtles.org.uk/girder/CTMediaSetup2.9.exe

settings are saved when you close the setup screen rather than when girder is closed
volume can be changed by a variable amount
fast forward/rewind can be done by a variable number of seconds
option to realod the current track
fastforward and rewind works properly now
fixed error when clicking on menu title
menu can be navigated with numbers
menu size configurable
lua scripting (see CTMedia Lua.html in the manual directory for details) functions for editing the media library my be coming soon

[birty]

a small suggestion a standard format for documentation for plugins that add lua functions could be useful so that all the documentation looks the same

[Promixis]

We have a tech writer doing that :D

[Mark F]

Can we lowly developers ;) get a template to use so our documents can have an opportunity to look somewhat like Promixis documents? I wouldn't think you want your tech writer doing our documents, too. Or do you?

[Promixis]

We will have our writter do whatever you want :D Okay, within reason :lol:

We are greatful for any contribution to G and NR.

[birty]

[Ron]

> Girder OSD now used for main OSD

Does that mean the lua osd?

[birty]

yes it does

[Ron]

GREAT :-)

[birty]

We will have our writter do whatever you want :D Okay, within reason :lol:

We are greatful for any contribution to G and NR.
does this offer still stand? if so could i have the attached help file translated into the standard format (no rush)

[Promixis]

Sure, remind me once we get the G4 manual done and I will see if John still has enough cycles left to add this.

[birty]

is the documentation written in latex? if so it may be easier to supply a latex template so developers can make their own documentation

[Ron]

OpenOffice.

[birty]

i just assumed latex as you managed to easily produce both html and pdf versions

[Ron]

Yeah, it does seem like latex in that way.

[Ron]

Nostalgia, I haven't used latex since my thesis. Aah the good ol' days of 2 dimensional flow patterns in plasma. *shudders*.

[Rob H]

Tut, tut - canonically the orthography is LaTeX !!!

Another former LaTeX user

[birty]

http://www.birtles.org.uk/girder/CTMediaSetup2.14.exe

[quixote]

Birty, could I persuade you to implement one more feature please?
Maybe I've failed to find it, but I could not find any commands to play just one .wav or .MP3. I'd like to be able to play a sound over the output device of my choice, but not need a playlist file for it. Is this possible? Something like the win.playsound LUA command, but with your plugin. Then you could have the search for play list directories at startup optional or not search if nil.

Thanks for considering it.

[birty]

i finish work on friday so i may have a look at the weekend

[quixote]

Thanks. I really appreciate it. My multizone audio system is in place outside my front door, and I'm setting up a "front door answering machine" for when I'm sleeping or not around. :D

[quixote]

Looking at the LUA functions again while I try to organize my alarm system, I noticed that there's no LUA function for balance either. :oops: I know I'm asking for a lot, but it really would be useful.

[birty]

how do i implement a callback in delphi/c ? i want to be able to pass a lua function to a function in my plugin and when the function is complete call the callback (ie start playing a file and call the callback when the file ends)

[birty]

version 2.15 released
changes:
-Added lua function to play a file
-Added lua functions to set the output pan

http://www.birtles.org.uk/girder/CTMediaSetup2.15.exe

[quixote]

Thanks Birty!

Update: I just tried using this line and it doesn't work. I could not find an updated documment with the new syntax.



CTMedia:PlayFile ("D:\\Audio\\Sounds\\lockdown.wav")

Could you please let me know how I should be doing this? Thank you.

[birty]

i did update the document, but the problem there is you used a colon instead of a dot it should be

CTMedia.PlayFile ("D:\\Audio\\Sounds\\lockdown.wav")

[quixote]

:oops:

Thank you, sir.

Update: I still can't get it to work. Is there anything else I need to do before it will work?

[birty]

is anything displayed in the lua console? or in c:\mediaplayer.log

[quixote]

nothing is displayed in the LUA console, but my .log file gives me this:

is the ctosd file present in the luascript directory? also are you using beta 8

[quixote]

affirmative. (to both questions)

[birty]

try this one it should put the error code in the log file when it loads the file

[birty]

weird, that seems to indicate it cant find the script file, try this one:

[quixote]

YES! IT WORKS! :D

Thanks!

[birty]

do the osd work though? it probably only works because i changed it so that if the osd failed to load then the lua functions still work

[quixote]

Oh. :(

I tried:

CTOSD.Toggle()

and it doesn't work. The global CTOSD is nil.

[birty]

the full path to the script should now be shown in the log, is it correct?

[birty]

and "D:\Program Files\Promixis\Girder\luascript\CTOSD.lua" definately exists? i think i will need help from Ron on this one, this is the code i'm using if it helps

top:=lua_gettop(Ls);
LuaL_OpenLib(ls,'CTMedia',@(CTLua_Funcs[0]),0);
osdscript:=main.support.CoreVars.ExePath+'luascrip t\CTOSD.lua';
res:=lua_dofile(ls,pchar(osdscript));
if res<>0 then begin
if lua_isstring&#40;ls,-1&#41; then err&#58;=lua_tostring&#40;ls,-1&#41;
else err&#58;='';
addeventfmt&#40;'Could not load %s&#58; %d, %s',&#91;osdscript,res,err&#93;&#41;;
end;
Lua_SetTop&#40;ls,top&#41;;

[quixote]

Yes, it's there.

[Ron]

The scripts in the luascript directory are loaded automatically, you should not load them manually. What seems to be the problem?

[birty]

dunno, it works for me but quixote seems to be having problems, i dont put the scripts in the startup directory so that they are only loaded when the plugin is loaded. on quixote's installation lua_dofile is returning LUA_ERRRUN which as far as i can gather means that lua simply couldn't load the specified file

[Ron]

Ignore my last comment, I was thinking of the treescript directory.

Don check if you are starting Girder in the correct directory. So check if on the properties page for the shortcut of Girder the "start in" box is set to the correct directory.

[quixote]

I recreated my shortcut and made sure that it starts in "D:\Program Files\Promixis\Girder", where it's default install is. Unfortunately, it still does not work.

Birty, does it matter that I have not specified a library directory? I get the message everytime I start up, but I not being a user of MediaPlayer usually, I don't know which directory it is.

[birty]

it shouldn't do, you could try creating a small library using my database editor

[quixote]

OK, I'll try it out later. Is there no one else here that has been having a similar problem as I am? Please speak up if so. I'm really perplexed now. All of my other startup scripts seem to run fine.

[birty]

i dont know that very many people are using the plugin

[quixote]

That's a shame. It seems like it would be really great, if I could only get it working on my system.

[Ron]

How about this.
Let's get rid of the dofile, and try this code. It splits the load up in two steps and gives you an error feedback.



BOOL RunScript&#40;lua_State *L, char * filename &#41;
&#123;
int n;
const char *e, *r;

n = 0;
if &#40; luaL_loadfile&#40;L, filename&#41; != 0 &#41;
&#123;
e = lua_tostring&#40;L,-1&#41;;
luaprint&#40;L, e, "TreeScript &#40;RunScript 1&#41;&#58; "&#41;;
lua_pop&#40;L,1&#41;;
return FALSE;
&#125;
else
&#123;

lua_pushstring&#40;L,"_TRACEBACK"&#41;;
lua_gettable&#40;L, LUA_GLOBALSINDEX&#41;;
lua_insert&#40;L, -n-2&#41;;

if &#40; lua_pcall&#40;L,n,0,-n-2&#41; != 0 &#41;
&#123;
e = lua_tostring&#40;L,-1&#41;;
luaprint&#40;L, e, "TreeScript &#40;RunScript 2&#41;&#58; "&#41;;
lua_pop&#40;L,2&#41;; // error + traceback.
return FALSE;
&#125;


lua_pop&#40;L,1&#41;; // traceback.
&#125;

return TRUE;
&#125;

[birty]

try this one

[Ron]

In case you need luaprint.


void luaprint&#40;lua_State*L, const char * str, const char * from&#41;
&#123;
lua_pushstring&#40;L, "print"&#41;;
lua_gettable&#40;L, LUA_GLOBALSINDEX&#41;;
if &#40; from != NULL &#41;
&#123;
lua_pushstring&#40;L, PCHAR&#40;from&#41;&#41;;
lua_pushstring&#40;L, PCHAR&#40;str&#41;&#41;;
lua_call&#40;L, 2,0&#41;;
&#125;

lua_pushstring&#40;L, PCHAR&#40;str&#41;&#41;;

&#125;
&#125;

[quixote]

I'll try that file as soon as I get home from work. Thanks.

[birty]

have you removed osd.lua from the startup direcotry? (or has it moved ron?)

[Ron]

osd has moved into the /luascript directory. We are trying to keep the startup directory only for stuff that actually needs this.

[birty]

in that case quixote change the firt line in ctosd to
[code]require("osd.lua");[code]
and it should work

[Rob H]

Strictly speaking, the .lua is unnecessary there

[quixote]

in that case quixote change the firt line in ctosd to
[code]require("osd.lua");[code]
and it should work

No dice.

looks to me like the osd file is loaded.

[quixote]

Alas, when I try the code
CTOSD.Toggle&#40;&#41;, it does nothing but give me errors in the console telling me that I'm trying to index a nil table; CTOSD.

[birty]

that should be CTOSD:Toggle

[quixote]

I'm afraid that I tried that already.

[birty]

is the variable in the variable inspector (you do realise its in the ctmedia table dont you?), alos you can toggle the osd from the action tree, there is a ct media action in the girder group

[quixote]

Ah, ok, I see that the CTOSD is now loaded. before I could only see the main functions listed in the variable display. Also, the command works from the action tree, but not LUA.

[birty]

the full command should be:

CTMedia.CTOSD&#58;Toggle&#40;&#41;

[quixote]

arrrgggh

CTMedia.CTOSD:Toggle ()

just figured it out seconds before I saw your post. :)

Thanks!

[quixote]

I think the command:

CTMedia.PlayFile &#40;"D&#58;\\Audio\\Sounds\\lockdown.wav"&#41;
confused me a little about the table structure. I thought that CTOSD was another table. I should have looked at the variable inspector sooner, plus I just noticed at the top of the HTML help file it says
All of the following functions can be found in the "CTMedia" table, they are only available when the "Creative Media Player" plugin is loaded.
, but I think that maybe you should put it in a larger font like the blue commands because it is very easy to miss. All I saw when quickly scanning for the command was

CTOSD:Toggle()
Hides the OSD if it is showing, otherwise the OSD is shown.
and I assumed that the table was CTOSD. I'm awfully sorry for the inconvenience that I caused. :oops:

Can you please direct me to the updated help file? I can't seem to find it and it would not show on installation. I need to figure out how to change output devices, and I can't see the function in the variable inspector.

[birty]

it should have been installed in the manual directory, its called CTMedia Lua.html

[quixote]

just found it. Thanks!

This is much more clear than the other help file that I had.
I had to rename the last one to an .html file to view it. Probably something else that I missed. :-?

version 2.15.1 released
changes:
-Changed path to osd.lua in ctosd.lua

http://www.birtles.org.uk/girder/CTMediaSetup2.15.1.exe

[birty]

how do i implement a callback in delphi/c ? i want to be able to pass a lua function to a function in my plugin and when the function is complete call the callback (ie start playing a file and call the callback when the file ends)
any ideas?

[Ron]

int cb;

// function is at top of stack.
if &#40; lua_isfunction&#40;L,4&#41; &#41;
&#123;
cb = luaL_ref&#40;L, LUA_REGISTRYINDEX&#41;;
&#125;
else
cb = LUA_NOREF;


unreffing:



if &#40; cb != LUA_NOREF&#41;
lua_unref&#40;L,cb&#41;;


running:



lua_rawgeti&#40;L, LUA_REGISTRYINDEX, cb&#41;;
lua_pcall&#40;L, 0,0,0&#41;

[birty]

version 2.15.2 released
changes:
-Play File callback enabled
-Changed to using Girder logging for errors

Hi Birty. Thanks for the update.
I just can't figure out how to change the balance yet. I read this in the manual:



Set the output pan:
[CurrentPan] = CTMedia.SetPan([Pan])

Pan: Number 0..255. Value to set the pan to
CurrentPan: Number 0..255. The pan after applying the change
A pan of 0 is all the way to the left, 128 is in the middle and 255 is all the way to the right


but can you please give me a code example of panning all the way right, then panning all the way to the left, and then back to center? I'm sure it's a minor detail that I'm missing.

[birty]

--pan to the left
CTMedia.SetPan&#40;0&#41;
--pan to the right
CTMedia.SetPan&#40;255&#41;
--return to the centre
CTMedia.SetPan&#40;128&#41;

[quixote]

ah ha. Ok, thanks. I was wondering why there was an equation there

&#91;CurrentPan&#93; = CTMedia.SetPan&#40;&#91;Pan&#93;&#41;
It looked to me like I need to have to numbers in there from 0 to 255.

[birty]

the funciton returns the current value of pan, eg if you say setpan(256) it will return 255 as the actual value the pan was set to

[quixote]

It doesn't seem to work for me. I ran a test on the speakers that I'm using with my second sound device and the speakers turn out to be "back left" and "back right" for some reason, but I guess that's a hardware problem rather than the plugin.

[birty]

i might not be using the library correctly

[quixote]

Well, I need a new sound card because I'm using a really old one, so don't get too worried.
I'll do some more tests.

[quixote]

I don't think it's working, beacuse I was able to get sound from the front left and right, the center and the rear left and right using winamp and a WAV file that fearthedentist directed me to, but was unable to pan to either side using the plugin.
Sorry it took me so long to find this.

[birty]

you mean you are using a 4 channel wave file? im not sure that is supported in fmod

[quixote]

I'm only using it to test my speakers. I can't pan just to the left or right with any other WAV, either. Ok, let me just be sure that the wavs that I'm using are in fact stereo and I will get back to you.

[quixote]

Bad news. The panning does not work. Can anyone else confirm?

[birty]

you notice no difference at all? are any errors displayed?

[quixote]

There is no difference at all. There aren't any error messages either, but it does show "Media Player Balance 0%" and "Media Player Balance 100%" on the OSD when I try panning left and right.

[birty]

anyone using my mediaplayer plugin with the latest beta should remove the line require("osd")
from ctosd.lua as it is no longer nescesarry and will cause the plugin osds to stop working, Ron it would be nice if these sort of changes were in the list of changes in a new release, took me a while to figure out why all my osds had suddenly stopped working

[quixote]

Birty, did you ever have the time to look into the panning feature? I have an external/internal speaker all setup as left and right channels so that I can use it for certain sounds that don't require stereo, but need to be played in eitehr outside or inside. It would be really cool if I could have this tool to work with over my Christmas vacation. Sorry to trouble you.

[birty]

theres very little i can do about it, all i can suggest is that you try updating the sound card drivers, i could try some different options in fmod and see if that helps

[quixote]

Whatever you can do would be much appreciated. The sound device I am using for the "multizone audio" is built onto the motherboard of my computer. Not sure if that would involve flashing my BIOS, but I'd prefer not to if I don't have to.

[birty]

i sort of forgot about this one sorry, better late than never!
added some new lua functions,
1. CTMedia.SetDriver
takes one parameter which is the output driver to use
0=No Sound
1=windows multi media (default)
2=direct sound
3=a3d (only works on a few sound cards)
7=asio

2. CTMedia.SetHW
turn on or off hardware acceleration (only takes effect next time you load a file), is off by default. takes one parameter, true to turn on hw acceleration false to turn it off
