硬件加速SinkWriter示例 [英] Hardware accelerated SinkWriter Example
问题描述
有没有人知道，或者他们将分享他们自己的样本，这说明如何使用MF创建和使用SinkWriter来硬件编码NV12输入到h264？
我可以让我的代码在软件中工作，但我需要利用硬件编码资源来降低我的CPU使用率。 我正在使用戴尔Latitude E6450，配备AMD Radeon HD 8790M和Intel Core I7-4800MQ CPU。两者都应该支持
硬件编码，并且有MFT。
我非常感谢提示/建议/代码示例来解决这个问题。

我设法让AMD和英特尔快速同步工作，但请注意：
- 您无法使用MFTrace工具，因为这将始终发生： MFGetMFTMerit @ Merit验证
MFT @ 07AD3A00失败（hr = 80004005 E_FAIL）。提示：调试打印自己。
- 我只是设法让快速同步MFT与Win8.1一起使用，
不 Win7（不处理样本）
尝试使用IClassFactory做一些事情，在此主题中描述：

要更好地控制MFT创建。
// Carl
Does anyone know of, or have a sample of their own they will share, that illustrates how to use MF to create and use a SinkWriter to hardware encode NV12 input to h264?
I can get my code working in software, but I need to utilize hardware encoding resources to lower my cpu usage. I am working on a Dell Latitude E6450 with both an AMD Radeon HD 8790M, and an Intel Core I7-4800MQ CPU. Both are supposed to support hardware encoding, and have MFTs.
I would greatly appreciate tips/advice/code samples to correct this problem.

Hi,
I have managed to get both AMD and Intel Quick Sync to work, but be aware:
- You can't use the MFTrace tool because then this will always happen: MFGetMFTMerit @ Merit validation failed for MFT @07AD3A00 (hr=80004005 E_FAIL). Tip: Debug print by yourself instead.
- I have only managed to get the Quick sync MFT to work with Win8.1, not Win7 (does not process samples)
Try doing something with the IClassFactory, described in this thread:
https://social.msdn.microsoft.com/Forums/windowshardware/en-US/6da521e9-7bb3-4b79-a2b6-b31509224638/win7-h264-encoder-imfsinkwriter-cant-use-quality-vbr-encoding?forum=mediafoundationdevelopment
To get more control over the MFT creation.
