General / Semaphore?

« on: October 07, 2010, 05:18:40 pm »

It’s not that I can’t, I’d rather not too... keep library count to a minimum for maintainability sake. when it’s says SFML supports threading I didn’t expect it was partially supported. No worries, I went for a duo SFML / SDL until I find something more elegant.

And the rabbit hole goes deeper... std::thread(C++0x) is not implemented in VC++ 2010 and I`m not a fan of boost:: … at all.

I was hoping not to look back at SDL again…

General / Semaphore?

Basically, I`m  trying to convert this tutorial:

http://dranger.com/ffmpeg/tutorial03.html

It’s been a nightmare so far… I`m astonish by the lack of support with this, for this tutorials being about 7 years old. I was hoping to make an SFML version. I think video playback would be a great plus for SFML. All it is missing is the equivalent of:

SDL_CondWait();
SDL_CondSignal();

would this be a valuable feature to implement?

With a little guidance setting the audio streaming, it shouldn’t take much to make this work. But I can’t make it happen by myself so far.

Still digging,

Oh i see, that is very unfortunate... thx for pointing that out… just the wait condition would do… any library you would recommend beside SDL?

Greetings,

Is there an equivalent as SDL_CondSignal (Restart a thread wait on a condition variable) within the SFML threads... Semaphore?

thx

Audio / How to manage audio with SFML?

« on: October 04, 2010, 10:26:28 pm »

Hi Laurent,

Actually my real problem is to output audio from FFmpeg... honestly, I don't know where to start. Did you plan on extending this tutorial?

Audio / How to manage audio with SFML?

« on: October 04, 2010, 09:39:48 pm »

Greetings,

I thought I would be able to play sounds that way :

sf::Music music;
music.OpenFromFile("../Data/Music/canary.wav");
music.Play();

If music is destroyed the sound will stop playing. What is a common technique for handling several sound entities and music playback in SFML? A separate thread for each sound and/or wrapping a sound class?

Hi there,

Is anyone managed to make the audio work as well using FFmpeg and SFML?

Greetings,

Both x32 and x64 versions compile just fine but I'm having unresolved external symbol with the x64 version when linking it to my project:

would be nice to simply turn on and off external libs.

General / SFML x64 cause QT to stall... window.lib compatibility issue

« on: August 14, 2010, 05:03:20 am »

Another example is that I'm linking my project library (including sfml-window-s.lib) to a Softimage 2010 C++ plug-in. When loading the plug-in, Softimage gets stall before any plug-in callbacks are being executed. I never had that problem before with SDL and I'm using a few other libs like FMOD and Nvidia Physx.

I m currently working on building an DLL + LIB... but I m having trouble with:

template __declspec(dllexport) std::vector<int>;

seems to be a well known issue but I cant get it to work yet... what a nitghmare that is!

Humm… can I link SFML to my project with Freetype enabled and turn it off without recompiling SFML?

« on: August 13, 2010, 02:33:58 am »

After recompiling every libraries with /MD I’m getting the exact same results… Oh well, at least I’m having all the latest libs now  

Quick question: when A.lib is compiled using lib.B… is it possible to link lib.A without lib.b?

General discussions / SVN repository?

Hi I m using TortoiseSVN and when I check out :

http://sfml.svn.sourceforge.net/viewvc/sfml/branches/sfml2/

I get:

Repository moved temporarily to '/viewvc/sfml/branches/sfml2/'; please relocate

I'm not used to SVN so I'm not sure if it is on my side or not.

Thx
