If the functionality of update_pipeline_state were moved to the validation stage of Set(Input/Output)Type, yes, that'd be possible. I'll do that.

I agree, even in the later patches where it does more, it just does the same thing twice for both the input and output type. It makes more sense to include it inline.+

/* audioconvert needs a valid channel-mask */
Well, that's not quite true, at least from my reading of the source, but it does need a valid channel mask for configurations other than mono or stereo.
The code below is confusing, though; I'm not sure why channel-mask would be present in the caps at all.
Note that a simpler way to set the channel mask is to use gst_audio_info_to_caps() in caps_from_mf_media_type().

This code is very strange. Isn't it easier just to validate "count == 1"? And is it really correct to return MF_E_INVALIDSTREAMNUMBER if more than one sample is passed?

Well, that's not quite true, at least from my reading of the source, but it does need a valid channel mask for configurations other than mono or stereo.
The code below is confusing, though; I'm not sure why channel-mask would be present in the caps at all.
Via MF_MT_AUDIO_CHANNEL_MASK.
Note that a simpler way to set the channel mask is to use gst_audio_info_to_caps() in caps_from_mf_media_type().
Mind if I just move this functionality to caps_from_mf_media_type? I remember having problems with gst_audio_info_to_caps.

I don't think that makes very much sense in general, no. What problems did you have with gst_audio_info_to_caps()?

I don't remember unfortunately. I'll give it another shot and report back, although I'm starting to have doubts about whether or not we want channel-mask to be set when MF_MT_CHANNEL_MASK isn't.

This is some confusing spacing. I expect either a blank line after all declarations or no blank line at all, but this makes me think "wait, where's input_types declared?"
Separately, I think it'd be better just to use MFT_REGISTER_TYPE_INFO directly in your "struct mft", and avoid allocation. It'd have to be non-const (or duplicate GUID definitions), but I think that's less awkward on the whole.
for (i = 0; i < cur->input_types_count; i++){input_types[i].guidMajorType = *(cur->major_type);input_types[i].guidSubtype = *(cur->input_types[i]);}for (i = 0; i < cur->output_types_count; i++){output_types[i].guidMajorType = *(cur->major_type);output_types[i].guidSubtype = *(cur->output_types[i]);}hr = MFTRegister(*(cur->clsid), *(cur->category), cur->name, cur->flags, cur->input_types_count,input_types, cur->output_types_count, output_types, cur->attributes);heap_free(input_types);heap_free(output_types);if (FAILED(hr)){FIXME("Failed to register MFT, hr %#x\n", hr);return hr;}- }

This registration could also be a separate patch.

Why S_OK?
Because the media session sends some messages to the transform such as MFT_MESSAGE_NOTIFY_BEGIN_STREAMING and fails to play if S_OK isn't returned. I take it you'd like me to actually implement this method instead.
Why not CLSID_CResamplerMediaObject? In fact, we already have one application that needs it (bug 47781).
The only reason I didn't expose it as CLSID_CResamplerMediaObject is that I didn't want to imply that I was basing the interface and types supported off of that specific object. For instance, that object, from what I can see on the MSDN, doesn't support PCM<->Float conversions, and vice versa. Is this not a big enough deal to keep it separate?

Not necessarily, but if nothing needs to be done, then presumably there shouldn't be a FIXME either, and it's not obvious to me what needs to be done. Sorry, I guess that comment should have been more specific.

Yes, from what I've seen the SAR usually only supports one or the other, at-least on wine. Exposing a PCM and Float type from the source doesn't solve this either, as the application doesn't have to specify ENUMERATE_SOURCE_TYPES when loading the topology, and in practice, rarely does, so the topology loader is forced to work with whatever the default type happens to be. It may be that on windows the decoders almost always expose both a PCM and floating point type, but currently, we are not using decoder MFTs in wine (and instead decoding in the media source). In practice, what this means is that without PCM<->Floating Point capabilities, Borderlands 3 doesn't work.

The SAR on wine, at-least on my system, only accepts one input type (the one derived from IAudioClient::GetMixFormat). So we need to be able to convert the one media type we are allowed to use from the source to the one media type the SAR supports. Naturally, you end up with cases where one is floating point and the other is PCM.

It would be nice to confirm whether this is the case.
At-least for the MFTs I've seen so far, it is the case. (both the AAC decoder and WMA decoder guarantee a floating point and PCM output type)
In practice, what this means is that without PCM<->Floating Point capabilities, Borderlands 3 doesn't work.

Performance isn't really the concern—it's more code, and you really should be handling allocation failure.
Another solution could be to just use a fixed-size stack buffer.

Okay, I guess I'll do that. There's no limit to how many types you can register for the MFT so I'll just make a max of 100 for both input and output (so ~3.2kb of stack space).

That varies on a per MFT registration basis, some MFTs require more registration structs than others, since they have more input/output types. Unless you're suggesting I use a VLA?

No, simply use the maximum array size that any individual transform needs.

Performance isn't really the concern—it's more code, and you really should be handling allocation failure.
Another solution could be to just use a fixed-size stack buffer.
Okay, I guess I'll do that. There's no limit to how many types you can register for the MFT so I'll just make a max of 100 for both input and output (so ~3.2kb of stack space).
I think there's no need for that; just allocate as much stack space as you actually need.
That varies on a per MFT registration basis, some MFTs require more registration structs than others, since they have more input/output types. Unless you're suggesting I use a VLA?
No, simply use the maximum array size that any individual transform needs.
Not looking forward to the bugs that show up from somebody adding more entries to the supported types list and not increasing the array size just so we can avoid two heap_allocs, but ok.
