[p***@labocom.com]

Hello Vadim,

function wxMediaCtrl::Load(filename)
since i upgrade wxWidgets to version 2.8.12
Before, i was on version 2.6 and my app don't crah : playing wav et mp3
file ...
The compiler used is Borland Builder 5.
The OS used is Windows7
Then, i wanted to compile mediaplayer sample to verify ...
The sample compile et execute until i open a file from the menu.

Hello Igor,

3.0.0 is out.
Can you try with the latest release?

I don't speak about a 3.0.0 version ... ?

Also it would be nice to have a backtrace of the crash...

I am confused ... it is not a crash.
but the function 'Load' of wxMediaCtrl class, used to load a media file,
return false.
By step to step in debug mode, i recompose the function's call :

bool wxMediaCtrl::Load(const wxString& fileName)
bool wxAMMediaBackend::Load(const wxString& fileName)
bool wxAMMediaBackend::DoLoad(const wxString& location)

here a call is execute :
HRESULT hr = GetP()->Open( wxBasicString(location).Get() );
and a DirectShow Error is send because :
if(FAILED(hr))

Regards and thank you,
Pierre

Igor,
No, i would like my app work with 2.8 ...
What are the benefits of 3.0 version ?

Problem is nobody will look at 2.8 since 3.0 is out and the cycle is
actually very close to 3.0.1.
So if you program, or even the sample, will not work with 3.0, someone
might look at it and fix it.
It's been a long time since 2.8 was out...

Also it will help to narrow down the problem. If it didn't work with 2.8,
but started working with 3.0
then you can upgrade without any major issues. All you will need to do is
to fix some compilation
problems and retest.

BTW, what is you operating system? And did you try to compile the media
sample?

I think you said you were using Borland compiler, right? Which means you
are on Windows.
Did the OS got any updates? Did you install anything that might interfere
with the normal processing
of that file? Can you open a player (WIndows Media Player, Real Player or
any other) and play
this file successfully?

You can find the sample in the samples/directory...

Unfortunately not everybody here speaks French. ;-)
Now this error is better be forwarded to wx-dev.

Or better yet, report this error to the libtiff developers....

Coming back to you problem: can you compile the library with libtiff turned
off?

Unfortunately, I don't have Borland compiler, so please check with the
wxWidgets build instructions....

Or post on wx-dev for further instructions and about this error.

Thank you

I'm afraid nobody bothered to check compilation of wxWidgets 3.0
pre-releases with this compiler and so it doesn't work (here the problem
seems to be that it doesn't support "LL" suffix on TIFF_UINT32_MAX constant
defined just above, but this is probably not the last problem you're going
to have).

If you can fix compilation with it, it would be nice and would help other
users of this compiler.

Hi Vadim,
I'am Ok with you when you say this compiler is out of date.
We start programing our app (Mivisu) nearly 1995 with borland c++ 5.02
compiler et we continue to use it because it's working very well in mode
console.
For IHM, we start with Borland C++ Builder 3 ... to 5 ... in VCL ... then
wxWidgets 2.6
Include headers of our libraries is completely Borland structure.
One day, i try to compile with VisualC++ ... I abandoned, the structures
are different, too much work...
I go and look of the highly-rated of Mingw ...
