I'm making audio decoder MFT and using AudioRenderer as a sink.
I tried to dynamic chage MF_MT_AUDIO_SAMPLES_PER_SECOND. it didn't work.
I tried to chage 44.1khz to 48khz. GetOutputAvailableType() was called and I set 48000to MF_MT_AUDIO_SAMPLES_PER_SECOND. after that SetOutputType() was called but MF_MT_AUDIO_SAMPLES_PER_SECOND was still set to 44100.
I all so tried to dynamic chage MF_MT_AUDIO_NUM_CHANNELS 6 channels to 2 channedls and MF_MT_AUDIO_SAMPLES_PER_SECOND at same time.
Channels and MF_MT_AUDIO_SAMPLES_PER_SECOND changed succesufly.
How to dynamic chage MF_MT_AUDIO_SAMPLES_PER_SECOND with out chaging MF_MT_AUDIO_NUM_CHANNELS
Thanks.

MF_MT_AUDIO_SAMPLES_PER_SECOND can't dynamic chage

The MF audio renderer doesn't handle dynamic changes between sample rates.
But it should be pretty easy to do the dynamic format changes you want to do in audio: Put a resampler MFT in your topology just upstream of the output node for the audio renderer. Vista has an audio resampler availabler which you can get to through MFTEnum (category=MFT_CATEGORY_AUDIO_EFFECT). This MFT will handle a changing input type.
