要在WPF中完美的支持YUV数据的显示，通常的解决方式是使用先把YUV数据转换成WPF可以支持的RGB数据，然后利用类似于WriteableBitmap的控件，把他展现在WPF上。这么做的主要问题是在做RGB转换的时候，需要消耗大量的CPU， 效率比较低。一种优化方式是使用FFMPEG里的SwScale或者Intel的IPP库，这些库经过了一定的优化，可以有限度的使用硬件加速。这里2为一个使用WritableBitmap的例子。(To perfect support in WPF YUV data show, the usual solution is to use the first WPF YUV data into RGB data can be supported, and then use controls similar to WriteableBitmap, and put his show on the WPF. The main problem is that in doing so make RGB conversion, consumes a lot of CPU, the efficiency is relatively low. An optimization approach is to use FFMPEG Lane SwScale or Intel' s IPP libraries that after a certain amount of optimization, can limited use hardware acceleration. 2 Here is an example of a use WritableBitmap.)
