GPUImageMovie removeTarget crash

[hoangdado]

Hi all,

I got this error "*\ Collection <__NSArrayM: 0x13987aca0> was mutated while being enumerated." when I trying to call removeTarget method on GPUImageMovie object. It crashed in method - (void)processMovieFrame:(CVPixelBufferRef)movieFrame withSampleTime:(CMTime)currentSampleTime at following code snippet:

for (id<GPUImageInput> currentTarget in targets)
            {
                NSInteger indexOfObject = [targets indexOfObject:currentTarget];
                NSInteger targetTextureIndex = [[targetTextureIndices objectAtIndex:indexOfObject] integerValue];
                [currentTarget setInputSize:CGSizeMake(bufferWidth, bufferHeight) atIndex:targetTextureIndex];
                [currentTarget setInputFramebuffer:outputFramebuffer atIndex:targetTextureIndex];
            }

How can I fix this problem?
