intel libva utils ( h264decode ) produced decoded output with green blocks all over

[sivarub]

produces corrupted decoded output. This is easily reproducible with given stream

h264decode /uhome/media/big.h264 /tmp/b5.yuv
You need retry few times. first attempt may not produce the issue.

input stream is extracted h264 stream from Big_Buck_Bunny_1080_10s_1MB.mp4

You will see green blocks on produced decoded output when you play using ffplay
ffplay -f rawhide -pixel_foramt nv12 -video_size 1920x1080 -I b4.yuv

I can share input stream and produced decoded ouput (yuv)
