 BinaryWriter b    =    new Binary_Writer(t);
 b.write(videoData);
 t.close();

解码b64，试试这个库：https://github.com/l4u/NSData-Base64

像这样使用它：

NSString *videoPath = '...'; //output path for the video.mp4 
NSString *encodedString = '...'; //the encoded "data"
NSData *decodedData = [NSData dataFromBase64String:encodedString];
[decodedData writeToFile:videoPath atomically:NO];
