IMFTransform::SetInputType() 'MF_E_TRANSFORM_TYPE_NOT_SET'

[英]IMFTransform::SetInputType() 'MF_E_TRANSFORM_TYPE_NOT_SET '

問題描述

我正在嘗試設置編碼器 IMFTransform。 在這種情況下，它恰好是 NVENC H264 編碼器。 但是， IMFTransform::SetInputType()不適用於ConfigureEncoder() ，並且正在返回MF_E_TRANSFORM_TYPE_NOT_SET 。 盡管代碼幾乎相同，但在ConfigureColorConversion() function 中不會出現此行為。 我幾乎嘗試了所有方法，但根本沒有幫助。

MF_E_TRANSFORM_TYPE_NOT_SET在設置輸入類型之前必須設置 output 類型。

這是設計行為。 您通常會沿着數據流構建管道，但在編碼器的情況下，由於我在這里省略的原因，它通常是反向的。 如文檔所述，錯誤代碼會提示您首先需要SetOutputType ，然后才能執行SetInputType 。

盡管 Video Processor MFT 也是一個 MFT，但它的類型設置更加寬松。
