but this .mkv vc-1 plays Hardware decoded perfectly fine with the Stock RockChip Player and MX Player

Oh yeah. There could still be bugs in there, and, as I said, the next version should solve the one for VC-1 and others

as here for H.264 you get the response from the Decoder with it's registered OMX component name
which is somehow not the case in the above VC-1 fail which just sends it failed to open the profile but not it's component name i find this somehow strange

Well, the message says it couldn't find a component to play the file. It can hardly give you the name of a component, then
