AV1 encode & decode build issue

[waiwaiwai]

Thanks for your help! I am able to generate the aom executable files now 

However, when i run with my test video sequence with the CLI line below, the encode process will stuck at the second pass. 

CLI:
aomenc  --end-usage=vbr  --target-bitrate=1000  --kf-max-dist=60  --width=720  --height=480  -o output.yuv  test_420_10bit_720x480.yuv

Output:
Pass 1/2 frame 1800/1801  331384B    1472b/f   44184b/s   32672 ms (55.09 fps)                                       
Pass 2/2 frame   19/0          0B   32701 ms 34.86 fpm [ETA  unknown]             

Do you have any idea on this? and my input yuv is 900 frames, I wonder why the 1/2 pass will have frame=1800/1801.
