Reproduce Steps:
--------------------------
rm -rf /root/.cache
rm -rf /root/.gstreamer-1.0/*
setting gstreamer folder path and export them
export PATH LD_LIBRARY_PATH PKG_CONFIG_PATH GST_PLUGIN_PATH
Dump yuv raw data based on SA00048.vc1, we got reference decoder dumped ref.yuv and gstreamer-vaapi dumped dump.yuv.
Compute the ssim value between ref.yuv and dump.yuv and got the following detail, these value should not lower than 0.99 expectedly.

ssim results:
--------------------------
Y_MIN_SSIM =     0.988264
Y_AVERAGE_SSIM = 0.991931
U_MIN_SSIM =     0.997890
U_AVERAGE_SSIM = 0.998083
V_MIN_SSIM =     0.997721
V_AVERAGE_SSIM = 0.998019
