Unable to build

[oriolgual]

Hi,

I've successfully built FFmpeg but I'm unable to build with XCode.

The error is:

~/path/to/kxmovie/kxmovie/KxMovieDecoder.m:1393:25: warning: 'avpicture_deinterlace' is deprecated [-Wdeprecated-declarations]
                        avpicture_deinterlace((AVPicture*)_videoFrame,
                        ^
ffmpeg/libavcodec/avcodec.h:4626:5: note: 'avpicture_deinterlace' declared here
int avpicture_deinterlace(AVPicture *dst, const AVPicture *src,

The docs of avpicture_deinterlace say indeed that is deprecated and to use yadif (in libavfilter) instead.

Is this related to my FFmpeg version? Anyone know how to fix it? Also, I'm using Xcode 4.6.1

Hm, But it's not error, just warning.

I've updated FFMpeg to 1.2, and I still see the warning and another error:

[oriolgual]

Rebuilding now with the updated gas-preprocessor.

[oriolgual]

Thanks for the quick fix, I've succesfully built it now!

Just another quick question (I'm really new to this): how am I supposed to run the example app in the simulator? If I open the project at Xcode an click on run it just says Build Succeed but it does no open the simulator (using 6.1).

[oriolgual]

Can it be related to this? (red text)

Sorry to ask such basic questions.

[oriolgual]

I only have iOs 6.1 at /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs, how can I change the project to use 6.1 instead of 6.0?
