I want to change the playback speed of asf file, i query the IAMExtendedSeeking interface, and then use its put_PlaybackSpeed(double Speed) method, but if the parameter Speed is not 1.0f, it will aways return E_INVALIDARG(0x80070057), in other words, this method can't change playback speed, what should i do
