Comment (by Florian Grill):

 Should I make a patch pull request for this MAX_SLICES issue in the
 dxva2_h264 file or why isn't there already a pull request for it? It would
 fix at least the slices limitation for DXVA2 and D3D11VA. Should be a one
 liner fix, I have to check what's the standard procedure for making a pull
 request but should not be that difficult I guess?
