Hi everyone.
recently I update my Tx2 jetpack to R32, when I use omxh264dec to decode 1920*1080 h264 video, there will be wrong information at the bottom of the video. A gray line appears at the bottom of some videos. I did not have this problem in the environemnt of the R28 I used in the past.

I found that if the resoultion is not divisible by 16, the bottom of the video decoded with omxh264dec has proble. But it can be played normally with vlc or ffmpeng.
I have tried using nvv4l2decoder insteaded of omxh264dec and this problem will not occur. But for some reason I can only use omxh264dec. So I want to know the cause of this problem and how to solve it.
