Hi.
When I try to start start vlc (0.8.4a and nightly 20060218) from the commandline without the full Path, vlc does not start (WinXP and wine). (the VLC-Directory in in the Path and my cd is somewhere else)

WinXPsp2 does not Print any text on the commandline

wine:

Code: Select all

~/wine.cvs/dosdevices/c:$ wine vlc.exe
VLC media player 0.8.5-svn-20060218-0001 Janus
[00000026] main interface error: no interface module matched "hotkeys,none"
[00000026] main interface error: no suitable intf module
[00000001] main vlc error: interface "hotkeys,none" initialization failed
[00000027] main interface error: no interface module matched "any"
[00000027] main interface error: no suitable intf module
[00000001] main vlc error: interface "(null)" initialization failed

When I try to start vlc.exe with the full Path, vlc comes up on WinXP and wine. (Example: "c:\Programme\VideoLAN\VLC\vlc.exe")

when using "vlc.exe" on WinME, vlc start succesful.
argv[0] includes the full Path on WinME, but not on WinXP and wine.

Possible Solution may be GetModuleFileName(NULL....) instead of argv[0]

Any Ideas/comments?

The DOS box when entering DOS commands does NOT recognize long file names!

So the command would be: "c:\progra~1\videolan\vlc\vlc" and any options you want including a path to the media and file name.

try running with -vvv and looking at the very very verbose output

try running with -vvv and looking at the very very verbose output

I started with a clean "Application Data\vlc":

Code: Select all

detlef@p4:~/wine.cvs/dosdevices/c:$ wine vlc.exe -vvv

IMHO, "c:\plugins" and "C:\modules" are the problems. The same
is for the "locale", but there is no message from vlc about this.

when starting vlc.exe with the full path, "plugins" and "modules"
(and also "locale") have the correct path:

Code: Select all

detlef@p4:~/wine.cvs/drive_c$ wine Programme/VideoLAN/VLC/vlc.exe -vvv

[00000001] main vlc debug: recursively browsing `C:\Programme\VideoLAN\VLC\plugins'
[00000001] main vlc debug: module bank initialized, found 209 modules

WinXP does not help at all (vlc is silent):

Code: Select all

d:>vlc.exe -vvv

d:\>which vlc.exe
c:\Programme\VideoLAN\VLC\vlc.exe

d:>

Thanks for your Help

The DOS-Box recognize long names for me since win95...

So the command would be: "c:\progra~1\videolan\vlc\vlc" and any options you want including a path to the media and file name.

That's the BUG: I must include the full Path

Expected:
just a simple "vlc.exe" works

it's not a bug. No programs work without including the full path in the dos shell, unless you put it in one of the directories listed in the PATH environement variable.

Use

Code: Select all

echo %PATH%

to check that. If you want to add the VLC directory to the path, run

Code: Select all

set PATH=%PATH%;"C:\Program Files\VideoLAN\VLC\"

.

To change the default path: open "System Properties", go on the "Advanced" tab, click "Environement Variables" and change the PATH.

Quotes from my Messages:

(the VLC-Directory in in the Path and my cd is somewhere else)

d:\>which vlc.exe
c:\Programme\VideoLAN\VLC\vlc.exe

Once Again the Bug in vlc:
vlc must started with the full Path to work from the commandline (Windows XP and wine)
On win9x (95/98/ME), the OS supplied the full Path in argv[0], but that is not the case for Windows XP.

It would be nice, if someone with write-Access to the trac-system can open a ticket.

I searched the source and found the bug in misc/win32_specific.c (system_Init):

Code: Select all

#else
    if( ppsz_argv[0] )
    {
        GetFullPathName( ppsz_argv[0], MAX_PATH, psz_path, &psz_vlc );
    }
    else if( !GetModuleFileName( NULL, psz_path, MAX_PATH ) )
    {
        psz_path[0] = '\0';
    }
#endif

    if( (psz_vlc = strrchr( psz_path, '\\' )) ) *psz_vlc = '\0';

    p_this->p_libvlc->psz_vlcpath = strdup( psz_path );

From MSDN: http://msdn.microsoft.com/library/defau ... thname.asp

GetFullPathName merges the name of the current drive and directory with a specified file name

When my current Directory is "c:\", GetFullPathname() returns "c:\vlc.exe", and finaly
p_this->p_libvlc->psz_vlcpath is "c:\".

Because of this Bug, vlc searches "c:\locale" (silent) and
[00000001] main vlc debug: recursively browsing `C:\modules'
[00000001] main vlc debug: recursively browsing `C:\plugins'

Fix: Throw away the Part around "GetFullPathName()"

Code: Select all

#else
     if( !GetModuleFileName( NULL, psz_path, MAX_PATH ) )
    {
        psz_path[0] = '\0';
    }
#endif

It would be fine to see an fixed vlc soon.
Thanks.

Hi dionoea.

http://trac.videolan.org/vlc/changeset/14452

Works great. Thanks for the fast fix.

I actually reverted that commit as it seems that it broke the mozilla plugin... i'll have to test a little bit more.

Why not using the --plugins-path command-line option (or maybe --plugin-path, i never remember)?
