媒体基金会新手问题 [英] Media Foundation newbie question

问题描述

我是Media Foundation的新手，仍然在为我们的新项目进行评估.

Hi,I'm new to Media Foundation and still evaluating it for a new project of ours.

我目前正在尝试在示例C ++中操作Microsoft H264解码器转换，该转换为它提供了从文件读取的纯H264比特流(PES).

What I'm currently trying to do is to operate the Microsoft H264 Decoder transform in a sample C++ which supplies it a pure H264 bitstream (PES) read from a file.

程序非常简单，仅创建一个Decoder实例并将其提供样本.

The program is very simple, merely creates a Decoder instance and feeds it with samples.

我使用pDecoder-> ProcessInput()馈入解码器，然后立即调用pDecoder-> ProcessOutput()，尽管馈送了来自文件的整个比特流，但总返回MF_E_TRANSFORM_NEED_MORE_INPUT.

I feed the decoder using pDecoder->ProcessInput() and immediately afterwards invoke pDecoder->ProcessOutput() which always returns MF_E_TRANSFORM_NEED_MORE_INPUT despite feeding it with the entire bitstream from the file which amounts to 70MB.

任何想法都将受到欢迎，甚至最好是重定向到完成类似功能的代码示例.

Any ideas would be welcome or even better a redirection to a code sample that accomplishes something similiar would be most welcome.

谢谢！

推荐答案

您可能要先介绍一些论坛搜索主题，例如:

you may want to start with a few forum searches on topics such as:

MF_E_TRANSFORM_NEED_MORE_INPUT
IMFTransform :: ProcessOutput

MF_E_TRANSFORM_NEED_MORE_INPUT
IMFTransform::ProcessOutput
