Question

output.videoSettings = [NSDictionary dictionaryWithObject:
    [NSNumber numberWithInt:kCVPixelFormatType_32BGRA]
    forKey:(id)kCVPixelBufferPixelFormatTypeKey];

この特定の行でこのエラーが発生します

このエラーの理由はありますか?

Answer 1

これを試して：

videoOutput.videoSettings = [NSDictionary dictionaryWithObjectsAndKeys:[NSNumber numberWithUnsignedInt:kCVPixelFormatType_32BGRA], (id)kCVPixelBufferPixelFormatTypeKey,
                             nil];
