The VideoLAN Forums

Hi,

I'm trying to build VLC 0.8.6c using MS-VS2005 for my Windows CE 5.0 / MIPS (Au1200) device.
The most of codec library are ported except ffmpeg(libavcodec, well somehow I managed to build with VS2005, but still has problems).

During the test, I use libmpeg2 to display MPEG video. It works fine with video output WINGDI module.
But, when I try with vout_directx, It doesn't display at all. Just black window screen.
(Yes, the device has DDraw.dll and it works fine with other applications. No problem at DDraw.dll side, I guess)

Here are debug message at vlc-log.txt. It clearly say 'DirectX is inizialized' but nothing happen.

Noone works on WinCE anymore, so this might be difficult to help you.

However, We are very interested in any version you can provide and any howto you can give.

You may want to ask damienf (mail and IRC) about DirectX problems.

About ffmpeg, it uses things that Microsoft Compiler does not understand. Maybe we should just crosscompile ffmpeg and do th rest under windows.

First of all, thanks for your attention.
I'll try to contact damienf via e-mail.

Regarding ffmpeg building issue, I would like to ask you few more questions.
1. I build libavcodec.lib, libavutil.lib, libavformat.lib, libpostproc for WinCE environment.
I have to deal with tons of compiling errors with VS2005. But somehow it was taken cared.
So, I'm wonder...even though, it still has run-time imcompatible with VS2005? Or just matter of compile issue?

2. As far as I know, in order to cross compile to WinCE device, I have to use arm-gcc-ce. It seems doesn't support MIPS core, but only ARMS core.
Is it possible to make a MIPS binary with arm-gcc-ce? If it is possible, I'd love and willingly to use that.

Thanks in advance.

1. I think it is only compiling problems. But you have to check since alignment is buggy in MSVC implementation.
2. Yes, or check the cegcc project.

Hi there!
Could you please show a tutorial/howto on how to use libavcodec/libavformat and ffmpeg on WinCE devices?
I'm also very interested on developing WinCE apps that use libavcodec/libavformat...

Thanks a lot in advance!

Can any body show me that where I could download the source code of vlc media player for windows CE 5.0 on MIPS processor (Au1200 board)? I look for a long time,thank you very much.
