Sorry, it's in French ...

Good luck, I believe we should use a callback on the window for the refresh...

just a quick word your doing something really bad in your code, not earth shattering but bad none the less;

Some of the API commands your using in libvlc are deprecated.
http://www.videolan.org/developers/vlc/ ... ylist.html

Don't know if that term is formilure to you at all, I've only noticed it myself around linux circles, basically deprecated means the functions are going to be gone soon, and there is no telling when they'll disappear, which is why I paid no effort in converting those for the Includes to LibVLC.

I couldn't figure out why you'd gone back to library() open calls, until I started making an example template to go with the (yet to be release new version of the includes), using your OpenLibrary() example as guide to get things done, and suddenly found missing commands, then I realized why they where deprecated.

It's not going to harm anything for now.. but it would be a good step to move away from them.

Using deprecated commands and then having to redo your whole code style to fit a new API it tiresome and time consuming.

Yeah i know Inner, i call it the 0.9 + and the 0.9 - way.

From 0.8.6 + new commands added, but using the new commands
i can't reload another file, so i can only load 1 file.

Code: Select all

    ;; 0.9+ way
    ;p\m = CallFunction(0, "libvlc_media_new", p\inst, p\file$, @p\ex) 
    ;p\mp = CallFunction(0, "libvlc_media_player_new_from_media", p\m, @p\ex)
    ;CallFunction(0, "libvlc_media_release", p\m, @p\ex) 
    ;p\drawable = GadgetID(3) 
    ;CallFunction(0, "libvlc_media_player_set_drawable", p\mp, p\drawable, @p\ex)
    ;CallFunction(0, "libvlc_media_player_play", p\mp, @p\ex) 
    ;p\reload=1
    
    ; 0.9- way
    p\item = CallFunction(0, "libvlc_playlist_add", p\inst, p\file$, #Null, @p\ex) 
    p\drawable = GadgetID(3)
    CallFunction(0, "libvlc_video_set_parent", p\inst, p\drawable, @p\ex)  
    CallFunction(0, "libvlc_playlist_play", p\inst, p\item, 0, #Null, @p\ex)

Thats why i use the old method in my sources, help me

Alright it's -all- in there I mean all the command even the deprecated.

Now.. I've not tested this at all, the example doesn't work at all really, and that's work in progress too, but it's better to have something out there that can be tested.

If it crashes check the argument types I've converted to PB are correct before blaming your own code, it's likely -very- likely my fault.

And feel free to slap me with what I did wrong so I can change it.

Wow nice work.. i needed to adjust some things to get it to
work on windows.

A few defs (17+/-) from ImportC like for example
libvlc_exception_init( *exception.l ) As "libvlc_exception_init"
only works like this:
libvlc_exception_init( *exception.l )

The drawable needed a compilerif because on windows
it uses a plain gadgetid().

The most strange things is, on windows you need to set
the defaultdirectory in compiler options in PB to the directory
where the libvlc.dll is. Otherwise a you get a error not finding
the dll.

Apart from this its multiOS already

I have bad luck getting PB to run on OSX BTW..

that's due to where windows looks for dlls; copy libvlc.dll into the source's directory (as this is where it would be in a finalised project, i.e. the exe's directory), or into the system32 dir (in system32 is not advisable if you ask me)

So it seems setcurrentdirectory() doesn't work with using ImportC on windows, it does work with using Openlibrary(). Strange..

For OSX i'm Going to try this:

I think ..

Uhmm there probably all like that you know, we're just using a small amount of the commands available so.. (ponders) I'll make a CompilerSelect on OS to select the right include of libvlc_linux.pb / libvlc_windows.pb / libvlc_macos.pb, where by you would just include as normal libvlc.pb and the compiler would choose the right one, appears the simplest way around this banana.

Philippe-felixer76-2 wrote: The most strange things is, on windows you need to set

You can redistribute the dlls/codecs for VLC it's open source as you likely know and GPL if I recall, just remember to include the verious legal bumbo jumbo, then it won't matter where it is as much.

The draw back of course is that you could have 2 conflicting versions of VLC on the same system, which could be problematic.

well, I'm sure someone out there using OSX even Fred might like to just look at that part of it, dunno you'd have to ask him, but right now if memory recalls his normal traditions at this time of year he has disappeared and rightly so, and if he hasn't he darn well should be off doing something other than working on PB or reading the forum.

not strange at all really... using openlibrary is like opening a file; it doesn't really matter where it is, but using Import/ImportC means that the exe is linked to the dll and cant function if windows cant find it.
From memory Windows looks in the exe dir, the current dir, then the system dir (perhaps not in that order though)
if on linux you moved libvlc from /usr/lib, you would get the equivalent error message

hehe i use OSX 10.4.8 in vmware (10.5.2 doesn't seem to like it)
OSX doesnt support my wireless card, i dont like to run an ethernet cable thru the house and my graphics card is too new, so running it w/o virtualisation is a hassle

And I don't really want to uhmm .. copy it .. although tempting I've wondered what that OS feels like to run.

Fixed: pbvlc_example.pb PBVLC_XDisplayFromWindowID() only required for linux

Changed: Split up the include files for each OS and made a central include to include only the include the source being compiled on.

Wow thats fast..

I forgot i little thing, apart from that it runs good here.

Linux:

Procedure PBVLC_MakeArgs(array Array.s(1), num, array newarr(1))
i = 0
Repeat
newarr(i) = AllocateMemory(StringByteLength(Array(i))+1)
PokeS(newarr(i), Array(i), -1, #PB_UTF8)
i+1
Until i>=num
EndProcedure

windows:

Procedure PBVLC_MakeArgs(Array.s(1), num, newarr(1))
i = 0
Repeat
newarr(i) = AllocateMemory(StringByteLength(Array(i))+1)
PokeS(newarr(i), Array(i), -1, #PB_UTF8)
i+1
Until i>=num
EndProcedure

Yeah but before i call ImportC is do a setcurrentdirectory() to
VLC. So the program directory should be good, and for OpenLibrary()
this works and is needed.

And can you run PB also?
