videoMinFrameDuration is Deprecated

gpuimage, ios7, objective-c, xcode

Solution

For one thing, you're using an outdated version of GPUImage, as this is has been fixed in the framework code for almost a year now. Update your local framework version.

The way I address this in GPUImage, since I still need to use this method for old iOS versions, is to disable deprecation checks around the relevant code:

    if ([_inputCamera respondsToSelector:@selector(setActiveVideoMinFrameDuration:)] &&
        [_inputCamera respondsToSelector:@selector(setActiveVideoMaxFrameDuration:)]) {

        NSError *error;
        [_inputCamera lockForConfiguration:&error];
        if (error == nil) {
#if defined(__IPHONE_7_0)
            [_inputCamera setActiveVideoMinFrameDuration:CMTimeMake(1, _frameRate)];
            [_inputCamera setActiveVideoMaxFrameDuration:CMTimeMake(1, _frameRate)];
#endif
        }
        [_inputCamera unlockForConfiguration];

    } else {

        for (AVCaptureConnection *connection in videoOutput.connections)
        {
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wdeprecated-declarations"
            if ([connection respondsToSelector:@selector(setVideoMinFrameDuration:)])
                connection.videoMinFrameDuration = CMTimeMake(1, _frameRate);

            if ([connection respondsToSelector:@selector(setVideoMaxFrameDuration:)])
                connection.videoMaxFrameDuration = CMTimeMake(1, _frameRate);
#pragma clang diagnostic pop
        }
    }

If the new property (`activeVideoMinFrameDuration`) is available, we use that. If not, it falls back to the now-deprecated method. Since we know it's deprecated, there's no need to have the compiler warn us about this.
