When using sample_decode to render 640x360 h264 stream which encoded by sample_encode, there will be green edge. But when using x264, or using sample_encode with a different resolution, it will be ok.
step to reproduce:
x264 --profile main --preset superfast --tune zerolatency --keyint 25 --vbv-maxrate 1500 --vbv-bufsize 1500 --input-res 640x360 -o x264.h264 camera_move_yuv420p_640_360_25fps.yuv -v
sample_encode.exe h264 -nv12 -i camera_move_nv12_640_360_25fps.yuv -o intel.h264 -w 640 -h 360 -r 1 -g 25
sample_decode.exe h264 -f 25 -i intel.h264 -r -w 640 -h 360(Green Edge)
sample_decode.exe h264 -f 25 -i x264.h264 -r -w 640 -h 360(OK)

x264 --profile main --preset superfast --tune zerolatency --keyint 25 --vbv-maxrate 1500 --vbv-bufsize 1500 --input-res 1280x720 -o x264.h264 camera_move_yuv420p_1280_720_25fps.yuv -v
sample_encode.exe h264 -nv12 -i camera_move_nv12_1280_720_25fps.yuv -o intel.h264 -w 1280 -h 720 -r 1 -g 25
sample_decode.exe h264 -f 25 -i intel.h264 -r -w 1280 -h 720(OK)
sample_decode.exe h264 -f 25 -i x264.h264 -r -w 1280 -h 720(OK)
