If I spoke to Pedro it was a lot easier to explain since both of us speak Portuguese ;)

Since I'm running out of time I have done one thing... I've generated static libraries of ffmpeg and add them on my Visual C++ project... Then when I build I get a lot of linking problems... To solve that I've copied all the .a's present on the lib folder of CeGcc and add them too to my project... It now compiles and links... I was surfing CeGcc page and I find out that to start I need a WinMain(...) function... So I create a new "Win32 SmartDevice Application" instead of a MFC application... Now it starts to run but gives me some weird errors on runtime...

That's a function from ffmpeg... If I remove that line the application works... Well, I hope that you can understand my problem... Perhaps if we speak on some IM program it will be better... I know that linking with all the CeGcc lib's is not the best solution but I'm really stuck on this :( Thanks for support > On Tue, 2007-01-16 at 11:13 +0000, Cool_Zer0 wrote: > >> Hi there, >> >> I have build ffmpeg with success (I guess!)... >> Now it's time to test it on a device/emulator... >> >> First I've put only the 3 dll's of ffmpeg on the same folder and the >> emulator keeps saying that a file is missing... >> >> After that I've installed Dependency Walker and stated that each dll >> from ffmpeg need a cegcc.dll. >> When I put that cegcc.dll it takes longer to appear something but the >> message "App is not a valid Pocket PC application" appears... >> Dependency Walker says that he can't find COREDLL, IPHLPAPI and >> MMTIMER... >> >> But seems that I don't have any coredll.dll :( >> # locate coredll >> /usr/ppc/arm-wince-cegcc/lib/libcoredll.a >> /usr/ppc/arm-wince-mingw32ce/lib/libcoredll.a >> >> >> Anyone can help me? >> Thanks >> ------------------------------------------------------------------------- >> Take Surveys.
