Processing Codec MFT Input and Output
When you have configured the input type and output type for an MFT, you can begin processing data samples. You pass samples to the MFT for processing by using the IMFTransform::ProcessInput method, and then retrieve the processed sample by calling IMFTransform::ProcessOutput. You should set accurate time stamps and durations for all input samples passed. Time stamps are not strictly required but help maintain audio/video synchronization. If you do not have the time stamps for your samples it is better to leave them out than to use uncertain values.
