From: "Chen,Wenbin" <[email protected]> Fix #9095. Qsv decoder assume that after calling seek funcion, the first frame should be key frame. However this is not true for some videos. If the frame is not key frame after seek(), there will be error. Conditional statements are added to skip these frame until reading a key frame.
