[Windows] Binaural output doesn't apply HRTF

[ThreeDeeJay]

I tried converting test_000086.iamf into binaural using default.tf:
iamfplayer.exe -sb -o2 "test_000086.iamf"
Output: binaural_test_000086.wav.zip

IN ARGS:
Output binaural
Output mode 2
Input file : C:\Programs\AOM Immersive Audio Model and Formats (IAMF) Player\test_000086.iamf
Binaural has 2 channels
===================== Get 3748 frames
===================== Get 240000 samples

But the file I get is just non-binaural stereo (HRTF doesn't seem to be applied).
If I set it to output 7.1 and virtualize it with something like HeSuVi, then I can hear externalization and positioning, so I'm not sure if I'm missing something or there's a bug with the binaural output mode or the HRTF file🤔

I put together a quick test here: iamfplayer binaural test.zip
Just gotta download default.tf manually since it's too big to attach here, then drag and drop the test_000086.iamf into Binaural.bat

Can you see if you have the problem with test_000096.iamf?

[ThreeDeeJay]

Yup, same result:
iamfplayer -sb -o2 "test_000096.iamf"

IN ARGS:
Output binaural
Output mode 2
Input file : C:\Programs\AOM Immersive Audio Model and Formats (IAMF) Player\test_000096.iamf
Binaural has 2 channels
===================== Get 236 frames
===================== Get 240000 samples

@ThreeDeeJay
Because libiamf will require bear and resonance libraries, which also require many third libraries. I did not provide them(I only provided linux libararies) in our git
So default, the Visual Studio solution dose not open this feature with preprocessor definition "DISABLE_BINAURALIZER"

If you want to use binarual feature, I can provide guide:
1, refer to https://github.com/AOMediaCodec/libiamf/blob/main/code/dep_external/README.md
Prepare all libraries(boost_filesystem.dll, boost_thread.dll, efl.dll, iamf2bear.lib iamf2bear.dll, iamf2resonance.lib, objectmodel.dll, panning.dll, pml.dll, rbbl.dll, rcl.dll, rrl.dll, visr.dll ) and place *dll in your working directory, please *lib in your building directory.
2, add preprocessor definition "DISABLE_BINAURALIZER=0" in iamf project of Visual studio solution.

Later I will think more how to enable binaural feature in Visual Studio solution.

Ah, that explains it. I'd appreciate an update to the VS solution to get more value out of #71, but I'll see if I can manage to do it with the manual method 👌
