hi
I have a problem:
I use Microsoft Dolby Digital Plus Decoder MFT to decode dolby eac-3 format audio file
I use MFAudioFormat_Float_SpatialObject for output type , create IMFSample to recive audio data.
when call IMFTransform->ProcessOutput , app crashed
I guess IMFSample is not correct.
Is there a decoder sampe for doblby audio for MFAudioFormat_Float_SpatialObject subtype
thanks.

Output Types
Subtype
MFAudioFormat_Dolby_AC3_SPDIF
KSDATAFORMAT_SUBTYPE_IEC61937_DOLBY_DIGITAL_PLUS
MFAudioFormat_Float
MFAudioFormat_PCMIt seems that the Dolby audio decoder don't support the MFAudioFormat_Float_SpatialObjects subtype.
Could you please tell us what is the return value of IMFTransform::ProcessOutput? And please show a minimal, reproducible sample without private information.
