Windows 10: Media Foundation AAC encoder raised minimum sample count for a valid conversion

Hi,We're using Media Foundation to convert WAV files to AAC/MP4 in our asset importer, and we observed that the smallest size of acceptable files increased in the later versions. Previously, we were able to convert files of at least 1025 samples, but now the new minimum appears to be 2049. We identified these minimum sample counts not because of errors returned by MF, but rather because the resulting files are empty. This was observed by comparing the 10.0.19041 to 10.0.22621. DLLs involved are likely `mf.dll`, `mfplat.dll` or `mfAACEnc.dll`, where the latter stands out as its size went from

AAC sample rates for N95

YES both 44.1 KHz and 48 KHz sample rates are supported for AAC.

You should use something "other" than Nokia Music Manager if you can. Like WINAMP or other audio encoder (SUPER) to convert files. Lot's of problems trying to use Nokia MM.

AAC sample rates for N95

Which AAC sample rates are supported by the N95 other than 44.1khz; is 48KHz supported for example?

If so is it possible to change the sample rate used within Nokia Music Manager?

Thanks,

Microsoft Media Foundation MPEG-2 audio encoder output playback is faster than the original

Hi,

Here's the link: https://docs.microsoft.com/en-us/windows/desktop/medfound/mpeg-2-audio-encoder

I just followed the instructions in setting-up the WMF encoder based on the link. 'Configuring the Encoder' part where I setup first the 'Output type', 'Input type', and I even setup the 'Codec Properties' (which can be optional)

I have successfully outputted a file based on the valid settings (sample rate, channels, and bitrate) however, the playback speed is always faster than the original speed.
