 When attempting to use the h264_qsv encoder on an Intel i7-4790K I run
 [h264_qsv @ 00000000070df020] Initialized an internal MFX session using
 software implementation
 [h264_qsv @ 00000000070df020] Using the constant quantization parameter
 (CQP) ratecontrol method
 [h264_qsv @ 00000000070df020] Error retrieving encoding parameters.

 This issue was introduced with 4d8f536b535487063a08609636e712ad86d2ad54

 Reproducing command was:
 ffmpeg -v verbose -i in.mp4 -c:v h264_qsv -b:v 2M -an -y out.mp4

 MFXVideoENCODE_GetVideoParam() in libavcodec/qsvenc.c is returning -3
 (MFX_ERR_UNSUPPORTED) and is triggering ff_qsv_error(ret).
