带有K5和K5000的vGPU与HTML5 Blast模糊不清，在Horizon 7中使用PCoIP很好

你能看看我的h.264博客流https://virtuallyvisual.wordpress.com/tag/h-264/吗？
任何看起来都很熟悉的......人工制品很有特色......

Can you check my h.264 blog stream https://virtuallyvisual.wordpress.com/tag/h-264/ ? Anything look familiar..... Artefacts quite distinctive...

一些进一步的测试继续缩小问题，我现在认为这是Windows的Horizo​​n 4.0.1客户端的一个问题。
我能够借用Mac并进行一些额外的测试，最终结果是Mac上的Horizo​​n客户端无论使用何种协议都能正常工作。
我需要做一些额外的客户端测试，看看我是否可以进一步隔离问题，但此时，它似乎与Windows客户端BLAST绑定。
我将不得不尝试禁用h.264以查看它是否可能与客户端解码相关的内容在平台之间以不同方式处理。
关于与编码有关的h.264工件问题，似乎有可能，但在这种情况下，我很惊讶VMware甚至会发布这样一个明显的用户体验问题。



以下为原文

Some further testing has continued to narrow the problem and I now believe it to be an issue with the Horizon 4.0.1 client for Windows.  I was able to borrow a Mac and do some additional testing and the end result was that the Horizon client on the Mac worked properly regardless of the protocol being used.  I need to do some additional client side testing to see if I can further isolate the issue, but at this time, it seems to be tied to BLAST with the windows client.  I'll have to try disabling h.264 to see if it might be something related to client side decoding being handled differently between platforms.  

Regarding the mention of h.264 artifact issues pertaining to the encoding, it seems possible but in such a case, I'm surprised VMware would even release it with such a glaring user experience issue present.

您描述了导致4：2：0 H.264编码工件的“投影”问题（演示图像附在博客中）。
如果您的问题看起来不同，您应该附上一些图片。



以下为原文

You described "drop shadow" problem that leads to 4:2:0 H.264 encoding artifact (demonstration image is attached in blog). If your problems looks different you should attach some image.

在这种情况下，Mac客户端也可能没有使用H.264。
您必须检查Blast日志以确定。
请注意，H.264固有地产生显示伪像，因为它使用YUV 4：2：0颜色空间转换，丢弃来自像素的75％的色度信息。
（参见：http：//connect.teradici.com/blog/the-importance-of-lossless-support）。
这就是为什么现代远程显示协议使用多个编解码器来编码计算机显示器并仅在适当的地方使用H.264而不是所有内容（参见：http：//connect.teradici.com/blog/why-you-need-
多编解码器换远程显示协议）。



以下为原文

It is also possible that the Mac client is not using H.264 in this scenario. You will have to check the Blast logs to be sure. Note that H.264 inherently creates display artifacts due to its use of a YUV 4:2:0 color space conversion that discards 75% of the chroma information from the pixels. (see: http://connect.teradici.com/blog/the-importance-of-lossless-support). This is why modern remote display protocols use multiple codecs to encode computer displays and use H.264 only where it is appropriate rather than for all content (see: http://connect.teradici.com/blog/why-you-need-multiple-codecs-for-remote-display-protocols).
