This isn't consistent with the actual ProcessInput() implementation, which refuses to accept more than one buffer.
I made some tests before, the tests show that for WMV decoder DMO, calling multiple ProcessInput is OK. Should I added these tests to Wine?
(Also, not sure why I was removed as reviewer?)
Sorry, I thought the front end stuff should reviewd by Rémi only. I will not removed you as reviewer anymore for anything related to winegstreamer.
