[PATCH v4 0/8] MR7432: mp3dmod: Add future support for Float encoding and fix various discrepancies with Windows
This MR adds the ability to support float encoding (which will be used by the IMFTransform interface).
It also adds tests and addresses a number of small discrepancies discovered between the Wine and native implementation.
-- v4: mp3dmod: Ensure nChannels is greater than zero on input. mp3dmod/tests: Add test for nChannels = 0 on input. mp3dmod: Only allow 1/2 and 1/4 subsampling. mp3dmod: Return error if requested output format values don't agree. mp3dmod/tests: Test different output sample rates. mp3dmod: Add support for 32-bit sample size. mp3dmod/tests: Add test for 32-bit sample size. mp3dmod: Return S_OK in Allocate/Free Resources.
From: Brendan McGrath bmcgrath@codeweavers.com
MS documentation states: "If the DMO does not support this method, the method returns S_OK"

If the requested output type has a sample rate that doesn't equal the average bytes per second when multiplied by the block alignment, then Windows returns E_INVALIDARG.
Block alignment must also be the number of channels multiplied by the bytes per sample (bytes per sample being the requested bits per sample divided by 8). --- dlls/mp3dmod/mp3dmod.c | 4 ++++ dlls/mp3dmod/tests/mp3dmod.c | 2 -- 2 files changed, 4 insertions(+), 2 deletions(-)

So it does; thanks for that. I'll capture that in a test and (I think) move that logic back to `MediaObject_SetOutputType` (I think I only moved it out to add that flag).
OK - that's done. Makes the diff a lot smaller.
