It might be an \u00e2\u20ac\u0153old\u00e2\u20ac\u009d version of Intel Media SDK runtime but still it is expected that software is running fine in older environments as well.<\/p>\n

MFXVideoVPP_Reset<\/code><\/a> API is available since SDK API 1.0, there is nothing new with it. In certain scenario I use the API to change resolution of the processed video and
\nI respectively update mfxVideoParam<\/code> structure then MFXVideoVPP_Reset<\/code>, MFXVideoVPP_Query<\/code>, MFXVideoVPP_QueryIOSurf<\/code> all succeed – nice.<\/p>\n

The system is an i7-3571U laptop, that is equipped with Intel 3rd Gen CPU. MFX version reported is 1.11.<\/p>\n

When the reset sequence succeeds as expected, however further MFXVideoVPP_GetVideoParam<\/code> reports unchanged properties\u00e2\u20ac\u00a6 Hey, come on!<\/p>\n

I quote below feedback from Intel<\/a> I just found on a seemingly similar matter, enjoy:<\/p>\n

for some algorithm, MFXVideoVPP_Reset<\/code> is not supported, and it will return MFX_ERR_NONE<\/code> but no effect.
\nyou can try replace MFXVideoVPP_Reset<\/code> with MFXVideoVPP_Close<\/code> & MFXVideoVPP_Init<\/code> to make it work.<\/p><\/blockquote>\n

Just for the record the runtime there is producing weird D3D11 errors with a pretty straightforward texture scaling operation:<\/p>\n

1920×1080 and 1280×720 are mine, it is okay. Where the heck 352×288 comes from? With a frame rate built out of values from uninitialized memory… It is not only debug output, it is also a _com_error<\/code> E_INVALIDARG<\/code> exception in d3d11.dll, but MFX runtime plays this game internally and produces no failure on its application requested activity though.<\/p>\n
