[FFmpeg-user] Need help why this type video have orange colored block noise when played with OS X

[桃源老師]

Hello video experts...

This might not be related with ffmpeg.  But I appreciate that if you teach me something...

I have some videos which have orange colored block noise when played with OS X QuickTime player.  ffprobe (sorry a bit old) reports as follows:

With ffplay, Windows Media Player, or MPC-HC, these video playbacks fine, i.e. playback without orange colored block noise.
Also, If I re-encode those videos with the following ffmpeg command, the block noise have gone on OS X QuickTime Player.

$ ffmpeg -i /Volumes/SA25-TR1-U3SV-4/Downloads/029_3xplanet_CWP-131.mp4 -c:v libx264 -profile:v High -preset slow -crf 18 -c:a copy -metadata creation_time="2015-08-25 04:52:17" -y test.mp4


In addition, one of those videos can playback without noise on OS X.  But I can't find out the difference between noised one and non-noised one.

I already have workaround.  Do not playback those video with QuickTime Player.  But If I can, I'd like to know why only QuickTime Player playbacks block noised video...
