In addition, we replay the output .mp4 file, the rendering situation is also incorrect, especially for chroma vectors.

Comment 1 haihao 2014-03-24 05:26:43 UTC

You should use --fourcc to specify the format, for most YUV files, the format is IYUV (the alias of I420)

Comment 2 zhenxiang.li 2014-03-26 02:54:42 UTC

After add prama fourcc, I got the following result:
720p5994_parkrun_ter.yuv 0.932995 0.953949 0.911788 0.920043 0.927842 0.934705 604 604 0

Comment 3 zhenxiang.li 2014-03-27 02:01:34 UTC

Since the ssim is about 0.93, so reopen it.

Comment 4 haihao 2014-03-27 02:51:02 UTC

Don't define the criteria for this case.
