Hi,

It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated.

The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful. See the TestBot job for the details:

The full results can be found at: https://testbot.winehq.org/JobDetails.pl?Key=146742

This doesn't look right and we could return a hardcoded value just as well for now.

I'm not sure where this information comes from but if it really matters maybe we need a way to get it from the actual encoder?

The same question goes for `MF_MT_MPEG_SEQUENCE_HEADER`, is it possible to get it from GStreamer? Or does it simply not matter?

}

Fwiw we don't *have* to use these helpers for every check, I think they are useful to set common check patterns, but in this case it seems specific to this transform and something like that would be simpler and save the need for a new helper:

``` hr = MFCreateMediaType(&media_type); ok(hr == S_OK, "MFCreateMediaType returned %#lx.\n", hr);

/* Input type attributes should match output type attributes. */ for (i = 0; i < ARRAY_SIZE(to_set_attributes); ++i) { winetest_push_context("attr %lu", i); init_media_type(media_type, input_type_desc, -1); hr = IMFMediaType_SetItem(media_type, to_set_attributes[i].key, &to_set_attributes[i].item); ok(hr == S_OK, "got %#lx.\n", hr); hr = IMFTransform_SetInputType(transform, 0, media_type, MFT_SET_TYPE_TEST_ONLY); ok(hr == MF_E_INVALIDMEDIATYPE, "got %#lx.\n", hr); winetest_pop_context(); }

IMFMediaType_Release(media_type); ```

I would even consider dropping the loop and making individual checks, to avoid having to look for the actual values that are checked, up to you.

Similar comment here, and it may also be good to test only one attribute change at a time, to see which one have an effect on the output size.

This doesn't look right and we could return a hardcoded value just as well for now.

I'm not sure where this information comes from but if it really matters maybe we need a way to get it from the actual encoder?

The cbSize of output info is usually used for determining the output buffer size. So I think using a size that is large enough to hold the encoded sample will make things work. So I just use a uncompressed size here, which must bigger than the encoded h264 size.

...

The same question goes for `MF_MT_MPEG_SEQUENCE_HEADER`, is it possible to get it from GStreamer? Or does it simply not matter?

I'm not pretty sure for that. I'm planning to put it aside for now, and doing researh after we are starting to implement the actuall encoding code.
