We are using NAudio for MP4 to MP3 conversion. We are getting this error only for few MP4 files (not all MP4 files have this problem).
Unable to find an entry point named 'MFCreateMFByteStreamOnStreamEx' in DLL 'mfplat.dll'
The part of the code where this error is appearing:
_mfReader = new MediaFoundationReader(_mp4Bytes);
Where _mfReader is an instance of MediaFoundationReader class and _mp4Bytes is a byte arrray of the MP4 file. I googled and found another problem related to mfplat.dll but that is about DLL loading error and not the entry point problem. Please help me fix this error.
I was able to avoid this error by running my code on Windows 10. Looks like there is a codec that is not available in Windows 7 and previous versions of windows. Windows 8 and above have this codec.
