音频后期处理MFT [英] Audio post processing MFT

问题描述

我正在尝试访问  MFT在我的C＃metro应用程序中创建为WinRT组件DLL，用于音频后期处理效果。我遵循GrayscallTranform MSFT示例并能够创建WinRT组件DLL。 我使用MediaElement进行播放，使用
API addAudioEffect来加载音频MFT。 我的MFT支持8位和16位PCM音频格式，即使我设置了  MF_MT_MAJOR_TYPE为MFMediaType_Audio，MF_MT_SUBTYPE为MFAudioFormat_PCM，当我检查输入数据时，我总是得到BitsperSample
值为32位虽然我设置了它 作为MF_MT_AUDIO_BITS_PER_SAMPLE的16位。我想我的MFT是作为解码器加载还是用于音频后处理。

Hi , I am trying to access  MFT created as WinRT Component DLL in my C# metro app for audio post processing effect. I followed GrayscallTranform MSFT example and able to create WinRT component DLL .  I use MediaElement for the playback and its API addAudioEffect to load audio MFT.  for 8bit and 16bit PCM audio format is supported in my MFT and even though i set  MF_MT_MAJOR_TYPE as MFMediaType_Audio and MF_MT_SUBTYPE as MFAudioFormat_PCM when i check input data, i always get BitsperSample value as 32 bit though i set it  16bits as MF_MT_AUDIO_BITS_PER_SAMPLE. I wonder My MFT is loaded as decoder or for audio post processing.

如何配置我的MFT以仅处理8位，16位PCM数据当MediaElement用于wmv，mp3，mp4，wav，wma播放时。

How do i configure my MFT to process only 8bit, 16bit PCM data when MediaElement is used for wmv, mp3,mp4, wav,wma playback.

你好Niraj - 我们的媒体人现在正在度假，但我会看看这个并试着想出答案。

Hi Niraj - Our media guy is on vacation at the moment, but I will look at this and try to come up with an answer.
