System Information
Windows 7 64bits

Blender Version
Broken: Blender 2.69-r60958-win32-vc11 and 2.69-r60958-win64-vc11
Worked: Blender 2.69-8003f06-win32 and 2.69 stable

Short description of error
The experimental release of blender using VS 2012 doesn't load png images.

Exact steps for others to reproduce the error

Requirements:
1. Windows
2. Download the blender release http://builder.blender.org/download/blender-2.69-r60958-win64-vc11.zip
3. The demo.blend and the image 'blender.png' on the same directory. Yo can download the from: blender_bug_png.zip

Steps:
1. Move cursor to the 3D View and press the key 'P' or click on Game -> Start Game Engine.
2. If the image is loaded correctly the cube will turn green, if not it will turn red.

Extra steps:
1. Show the system console (Window -> Toogle system console).
2. If you look at the execution prints you will notice that when the texture doesn't load the LAST ERROR (print of bge.texture.getLastError()) is empty, why?

I will see if @JurgenHerrmann can take a look at this. We don't officially fully support vc11 yet (thus it's called experimental).

@Moguri / @kupoman are you building with vc11? can you confirm if this bug happens in master? (builtbot is way outdated for vc11)

I'm on Linux these days, so I'm using GCC. However, I'm guessing the ffmpeg library being used for the vc11 builds doesn't have PNG support.

This sounds familiar. I build with MSVC 2012, but I will need to wait until I get home to double check this.

I've compiled blender/blenderplayer from source (the 2.69 tag) with MSVC 2012 using lib/windows_vc11 and it's broken as the buildbot versions... Did anyone of you have different results?

vc 2012 is not supported officially yet, therefore marking as low priority.

Hi,

I'll look into this as soon as possible.
I took a brief look at this and found a problem with the FFmpeg libs. They seem to lack png support.
I'll rebuild the libs as soon as possible and upload them to SVN.

Hi there,

i recompiled the FFmpeg libs and assured that png, zlib and jpeg support was compiled in.
Unfortunately that doesn't seem to be the problem.

This needs some thorough debugging, unfortunately CMake is broken for VS2012 debug builds atm.
So i'll have to fix that first.

And then I'll need some help with python binding debugging and internal stuff I guess :D

It seems that this is something to do with the call to "avformat_find_stream_info". There is a helper method defined in a header file for API versions less than 54 (which thusly isn't defined for our usage in VS2013), but I'm not sure if we need that or not. Either way, it's at this function that the opening fails.

Does this work in VS2013 builds?

I just had the opportunity to test this with a clean debug build of blender made with VS2013.

As I will not continue the VS2012 port but, rather concentrate on supporting VS2013 i'll close this task.
Please use VS2013 in the future.

Another possibility to work around this is to replace the FFMpeg libs with the old FFMpeg libs of VS2008. That should work too.

I haven't been able to test it today, but the last time I did so, I was using the latest visual studio and it wasn't working. Tga files load fine. I'll report back when I've validated my claim.
