Comment (by atorp):

 Hi lizhong1008,

 Regarding the Linux / Windows difference, please note this part of code in
 "libavcodec/qsvenc.h"


 {{{
 #if defined(_WIN32) || defined(__CYGWIN__)
 #define QSV_HAVE_AVBR   QSV_VERSION_ATLEAST(1, 3)
 #define QSV_HAVE_ICQ    QSV_VERSION_ATLEAST(1, 8)
 #define QSV_HAVE_VCM    QSV_VERSION_ATLEAST(1, 8)
 #define QSV_HAVE_QVBR   QSV_VERSION_ATLEAST(1, 11)
 #define QSV_HAVE_MF     0
 #else
 #define QSV_HAVE_AVBR   0
 #define QSV_HAVE_ICQ    QSV_VERSION_ATLEAST(1, 28)
 #define QSV_HAVE_VCM    0
 #define QSV_HAVE_QVBR   QSV_VERSION_ATLEAST(1, 28)
 #define QSV_HAVE_MF     QSV_VERSION_ATLEAST(1, 25)
 #endif
 }}}

 The problem can definitely appear only in Windows because the compilation
 is different.

 Please test in Windows before anything else!
